Abstract

A pregnant sow limited feeding device belongs to livestock feeding devices. A feeding groove is arranged inside a supporting frame, two lateral wall supporting plates are arranged on two lateral portions at the upper end of the supporting frame symmetrically, a material-leaking conical drum is assembled on the two lateral wall supporting plates, a measuring drum and a material containing conical drum are arranged on the material-leaking conical drum sequentially, a lower material retaining drawing plate and an upper material retaining drawing plate are assembled between the material-leaking conical drum and the measuring drum and between the measuring drum and the material containing conical drum, a U-shaped limit support is arranged on two lateral wall supporting plates, a connecting rod is inserted onto the U-shaped limit support, a material-limiting retaining block is installed on the upper lateral portion of the connecting rod in matching mode through inner threads and outer threads, and an arch ring is assembled at the lower end of the connecting rod. The pregnant sow limited feeding device is simple in structure, reliable in working, capable of effectively limiting daily food-intake of pregnant sows and favorable for breeding of pregnant sows, saves labor and feed, and achieves scientific feeding.

Description

Pregnant sow restricted feeding device

Technical field

The invention belongs to livestock rearing equipment, relates generally to a kind of pregnant sow restricted feeding device.

Background technology

In recent years; Aquaculture development is rapid; The feeding device of scientific and reasonable control pregnant sow scale of feeding and easy saving never is well solved; Existing feeding device can not dosing on the market, and what have that every pregnant sow can not be balanced has an equivalent feed, influences the normal breeding of pregnant sow.

Summary of the invention

The purpose of the invention is exactly the problem that exists to above-mentioned prior art; Actual needs in conjunction with the livestock breeding breed; Design provides a kind of pregnant sow restricted feeding device, this kind pregnant sow restricted feeding device can realize that the dependence pig encircles and make the automatic limited whereabouts of feed, and not putty, flash not; The science of reaching is fed, and practices thrift feed, helps the purpose that pregnant sow breeds.

1, the purpose of the invention is achieved in that on the bracing frame inside portion crib is installed; Two sidewall support plate symmetries are installed on the position, both sides, bracing frame upper end; On two sidewall support plates, be positioned at the equipped material awl tube that leaks in position above the crib; Leaking equipped quantitation tube and the charge awl tube that material awl tube upper end is interconnected from bottom to up successively; But following backgauge pumping board and last backgauge pumping board pull respectively are fitted in Lou between material awl tube and quantitation tube and quantitation tube and charge bore tin movably; U type position-limited rack is installed on two sidewall support plates, and connecting rod can be inserted on the U type position-limited rack up or down, on the connecting rod upper lateral part, be positioned at and leak material awl tube tube and cooperate through internal and external screw thread and limit is installed expects block; Described limit material block outside wall surface cooperates with leakage material awl tube internal face contact matching or disengaging, and arch ring is fitted on the connecting rod bottom.

The feed pigs device of feed of constant volume is adopted in the invention; Satisfy dosing in the process of feeding; Rely on pig self consciousness and action to realize the purpose of blanking, have simple in structure, operation reliable, save manpower, sanitation and hygiene, prolongation feeding time, restriction pregnant sow food-intake every day, practice thrift feed, reduce the advantage of feeding cost.

Fig. 3 is the 3-D view of pregnant sow restricted feeding device.

Piece number explanation among the figure: 1, bracing frame 2, limit are expected block 3, sidewall support plate 4, following backgauge pumping board 5, upward backgauge pumping board 6, charge awl tube 7, quantitation tube 8, leakage expect to bore tube 9, U type position-limited rack 10, connecting rod 11, arch ring 12, crib

Embodiment

2, below in conjunction with accompanying drawing the invention embodiment is described in detail.A kind of pregnant sow restricted feeding device; Crib 12 is installed on bracing frame 1 inside portion; Two sidewall support plate 3 symmetries are installed on the position, both sides, bracing frame 1 upper end; On two sidewall support plates 3, be positioned at the equipped material awl tube 8 that leaks in position above the crib 12; Leaking the equipped quantitation tube 7 and charge awl tube 6 that material awl tube 8 upper ends are interconnected from bottom to up successively, but following backgauge pumping board 4 and last backgauge pumping board 5 respectively pull be fitted in material awl tube 8 and quantitation tube 7 and quantitation tube 7 and charge movably with Louing and bore between tins 6, U type position-limited rack 9 is installed on two sidewall support plates 3; Connecting rod 10 can be inserted on the U type position-limited rack 9 up or down; On connecting rod 10 upper lateral parts, be positioned at and leak 8 in material awl tube and cooperate through internal and external screw thread limit material block 2 is installed, described limit material block 2 outside wall surface with leak material awl tube 8 internal face contact matching or disengaging and cooperate, arch ring 11 is fitted on connecting rod 10 bottoms.Leak material awl tube 8 whole cone angle≤90 °.

Operation process is following: in feeds utilized adding charge awl tube 6, under the situation that backgauge pumping board 4 is closed down, will go up backgauge pumping board 5 and extract out; Material falls in the quantitation tube 7, will go up backgauge pumping board 5 and push back, and will descend backgauge pumping board 4 to extract out; Material will descend backgauge pumping board 4 to push back after falling into and Lou expecting in the awl tube 8; Pig relies on the habit of self; With the nose arch ring 11 that arches upward; The limit material block 2 that is connected on the connecting rod 10 is temporarily held up; A spot of feed falls in the crib 12, and limit material block 2, connecting rod 10 and arch ring 11 rely on self gravitation decline return, U type position-limited rack 9 restriction arch rings 11 raising heights; Control blanking amount; After material is eaten up, pig can be once more with the nose arch ring 11 that arches upward, the material in quantitation tube 7 is all eaten up.Through threaded engagement, regulate the high and low position of limit material block 2 on connecting rod 10, can adjust at every turn from leaking the forage volume that material awl tube 8 falls in the crib 12.
