Self-propelled agricultural three-wheel pressing machine
Technical field
The utility model relates to a kind of self-propelled agricultural three-wheel pressing machine, belongs to farm machinery technical field.
Background technology
In recent years, along with agricultural crop straw is gone back field in a large number, generally adopt rotary tillage soil-working mode in addition, cause topsoil soils fluffy, the ventilative loss of moisture is fast, and between wheat paddock, emergence rate significantly reduces; Meanwhile, because soil porosity is excessive, it is very general that 〝 hangs root 〞 phenomenon, wheat root depauperation, and Seedling Quality is poor, and winter, spring frost evil seedling death phenomenon are serious.Base this, Nationwide Agricultural Technology Promotion Service Center classifies 〝 wheatland suppression 〞 as one of the technology of promoting mainly greatly for 2013 five as.There are two large defects in the towed pressing machine of at present widespread use, and the one, trailer-type machine tire impression is excessively dark, the spreading place wheat difficulty of emerging, the 2nd, operating efficiency is low and transfer tasks is inconvenient, has restricted applying of pressing machine.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of self-propelled agricultural three-wheel pressing machine, improves rolling effect and operating efficiency.
To achieve these goals, the technical solution adopted in the utility model is: a kind of self-propelled agricultural three-wheel pressing machine, comprise frame, front-wheel support, front land wheel and rear land wheel, front-wheel support is arranged on the front of frame, front land wheel is arranged on front-wheel support, also comprise diesel engine belt pulley, change speed gear box, clutch pulley, cone belt, operator's saddle, diesel engine, shifter bar, bearing circle and rear extension rim, bearing circle is installed on front-wheel support, and operator's saddle is arranged on the top of frame; Diesel engine is arranged on the middle part of frame, and diesel engine belt pulley is positioned on diesel engine, and diesel engine belt pulley is connected with the clutch pulley on change speed gear box by cone belt; Shifter bar connects and controls change speed gear box, and described rear land wheel and rear extension rim are respectively two, and rear land wheel is connected in both sides, frame rear by rear land axle, and rear extension rim is fixedly connected with rear land wheel outside.
Described shifter bar is positioned at operator's saddle front.
Described rear extension rim is connected with rear land wheel by connecting pin.
The wheel wide of described rear extension rim is 40-100 centimetres.
The beneficial effects of the utility model are: the self-powered and running gear of the utility model, and simple in structure, easy to use and reliable, can be sitting in the enterprising line operate of machine by personnel, in the time suppressing operation, due to the effect of rear extension rim, can strengthen suppression fabric width, improve operating efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2: the utility model comprises frame 2, front-wheel support 10, front land wheel 11 and rear land wheel 14, front-wheel support 10 is arranged on the front of frame 2, front land wheel 11 is arranged on front-wheel support 10, also comprise diesel engine belt pulley 1, change speed gear box 3, clutch pulley 4, cone belt 5, operator's saddle 6, diesel engine 7, shifter bar 8, bearing circle 9 and rear extension rim 12, bearing circle 9 is installed on front-wheel support 10, and operator's saddle 6 is arranged on the top of frame 2; Diesel engine 7 is arranged on the middle part of frame 2, and diesel engine belt pulley 1 is positioned on diesel engine 7, and diesel engine belt pulley 1 is connected with the clutch pulley 4 on change speed gear box 3 by cone belt 5; Shifter bar 8 connects and controls change speed gear box 3, and described rear land wheel 14 and rear extension rim 12 are respectively two, and rear land wheel 14 is connected in frame 2 both sides, rear by rear land axle 15, and rear extension rim 12 is fixedly connected with rear land wheel 14 outsides.
In order to facilitate navigating mate operation, described shifter bar 8 is positioned at operator's saddle 6 fronts.
In order to make rear extension rim 12 be convenient to dismounting, described rear extension rim 12 is connected with rear land wheel 14 by connecting pin 13, in the time not needing to suppress operation, rear extension rim 12 is taken off, and is convenient to movement and the walking of pressing machine; When operation need to be suppressed, install rear extension rim 12.
In order to play better suppression effect, the wheel wide of described rear extension rim 12 is 40-100 centimetres.
The utility model in use, be sitting in the enterprising line operate of operator's saddle 6 by navigating mate, first start diesel engine 7, then shifter bar 8 is allocated to walking position, diesel engine belt pulley 1 drives clutch pulley 4 to rotate by cone belt 5, after driving change speed gear box 3 to drive, land axle 15 and rear land wheel 14 rotate, thereby drive whole machine walking, by front land wheel 11, rear land wheel 14 and rear extension rim 12 are suppressed farmland, by soil packing, complete suppression operation, in the time suppressing operation, due to the effect of rear extension rim 12, can strengthen suppression fabric width, improve operating efficiency.
