Description

The fertile seed broadcaster of centrifugal seed

Technical field

The utility model relates to proportion of crop planting machinery, is specifically related to a kind of centrifugal seed, fertile seed broadcaster.

Background technology

The realization of agricultural modernization be unable to do without agricultural mechanization.Be used for the crop planting aspect, agricultural activity drilling machine, planter etc. are arranged, these machineries have been brought into play positive effect for establishing in large scale wheat, corn, Soybean and Other Crops.But also having some rural areas because soil property hardens, use the drilling machine planting effect just relatively poor, and drilling machine can not apply particle fertilizer again simultaneously.Thereby this a slice immensely the peasant in territory adopt artificial broadcast's seed and particle fertilizer, and then use the rotovator farming, seed is fully contacted to be more conducive to plant growth with the native location of shallow table with fertilizer.Artificial broadcast's seed and fertilizer workload are big, and speed is slow, and the uniformity coefficient of sowing also depends on muscle power and the operating technology of sowing the people.

Summary of the invention

The utility model proposes the fertile seed broadcaster of a kind of centrifugal seed, purpose is that it is applied to the crop that need broadcast sowing and the farmland of the plantation that can only take to broadcast sowing, and reaching seed, fertilizer broadcasts sowing simultaneously and must ask, to increase work efficiency, alleviate peasant's labour intensity, the uniformity that seed fertilizer is broadcasted sowing is better.

Technical solution of the present utility model:

The utility model comprise four-wheel tractor and the belt pulley that is connected with the four-wheel tractor power take-off thereof, horizontal rotating shaft, bevel gear to, vertical rotation axis and the centrifugal wind wheel that is connected with vertical rotation axis and the hopper that is arranged on the centrifugal wind wheel form.Centrifugal wind wheel mainly is made of last disk, lower disc and the polylith dividing plate that is vertically set between the upper and lower disk, and dividing plate is arranged evenly along orientation such as the dish circumference are.Described hopper is provided with the blowing quantity regulating device.

The beneficial effects of the utility model:

(1) the utility model both can broadcast sowing seed or fertilizer separately, also can broadcast sowing seed and fertilizer simultaneously, had reduced peasant's workload, had saved the time that is used to plant, and had improved operating efficiency.

(2) the utility model amount of sowing, amplitude of broadcasting sowing of broadcasting sowing can be regulated by demand, broadcasts sowing job specification, broadcasts sowing good evenness.

(3) the utility model and four-wheel tractor use, and install simply, and easy to operate, safety is good.

Accompanying drawing 1 is the utility model overall structure schematic diagram;

Accompanying drawing 2 is the structural representation of the utility model component parts one centrifugal wind wheel;

Accompanying drawing 3 is the structural representation of the utility model component parts one blowing quantity regulating device.

Embodiment

As shown in Figure 1, the utility model mainly by belt pulley 1, horizontal rotating shaft 2, bevel gear to 3, vertical rotation axis 4, centrifugal wind wheel 5, hopper, hopper bracing frame 9 form.Centrifugal wind wheel 5 is connected the vertical rotation axis upper end.Hopper is made up of hopper 6, elevating hopper 8, is provided with blowing quantity regulating device 7 up and down between the hopper.

And for example shown in Figure 2, centrifugal wind wheel 5 of the present utility model mainly is made up of last disk 51, lower disc 53, dividing plate 53, divider upright is arranged between the lower disc, along disk circumference to etc. the orientation arrange, the transverse width of dividing plate (promptly with disk intersecting lens length) is less than 1/2nd of disc radius, greater than 1/3rd of disc radius, dividing plate is provided with six.

And for example shown in Figure 1, the bottom of elevating hopper 8 has two small openings 81; The hopper mouth of pipe of hopper 6 stretches in the centrifugal wind wheel 5, and mouth of pipe bottom is closed, and has discharge door 61 in the side direction of the hopper mouth of pipe, and the sealing surface of the mouth of pipe is by discharge door bottom acclivity face.

As Fig. 1, shown in Figure 3, the blowing quantity regulating device 7 that is provided with between the up and down hopper of the present utility model is mainly by adjustable plate 71, and extension spring and fixed head 72 thereof, are regulated 76 compositions drag-line and arm-tie 73, backstay 74, turning set 75.Wherein, adjustable plate 71 is provided with two charging holes 79, and an end of adjustable plate 71 connects extension spring and extension spring fixed head, and the extension spring fixed head is connected on the hopper bracing frame 9; The other end of adjustable plate 71 is connected with drag-line and arm-tie 73, and the other end vertical fixing of arm-tie is connected the top of turning set 75, turning set 75 is enclosed within outside the backstay 74, the backstay bottom is vertically fixed on the underframe of hopper bracing frame 9, regulate the bottom that 76 vertical fixing is connected turning set, and arm-tie is vertical mutually with the upright projection of regulating handle.In addition: the below of adjustable plate 71 also is provided with regulates platelet 77, also is provided with chute 78 on the plate body of adjusting platelet, regulates platelet and is connected with the bolt that is located in the chute with adjustable plate.

Below in conjunction with accompanying drawing, sketch the course of work of the present utility model:

Belt pulley 1 of the present utility model connects with the power take-off of four-wheel tractor, and horizontal rotating shaft, vertical rotation axis work drive the centrifugal wind wheel rotation, and seed, fertilizer in the elevating hopper will leak down from elevating hopper small opening 81.But when the charging hole 79 of the adjustable plate 71 of blowing quantity regulating device does not communicate with elevating hopper small opening 81 (as shown in Figure 1), seed fertilizer can not enter centrifugal wind wheel 5; As will regulate 76 rotate counterclockwise (regulate and the other end is connected braking stop---figure in expression), then turning set 75 drives arm-ties 73 with the adjustable plate layback, small opening 81 communicates with charging hole 79 contrapositions, then seed fertilizer drops to hopper 6, and the mouth of pipe side direction discharge door 61 from hopper enters centrifugal wind wheel 5 again.When centrifugal wind wheel rotates, just seed fertilizer is flown to spill from the dividing plate space and spread to the field, and owing to discharge door 61 is out in mouth of pipe side direction, so only spread the place ahead of advancing to seed broadcaster.In addition, also can adopt the adjusting platelet to regulate the size of discharge opening 79 and regulate load; By regulating pulley speed, regulate the centrifugal wind wheel rotating speed and realize that the amplitude of broadcasting sowing is adjustable.

To sum up, the utility model can reach the goal of the invention of expection.
