Description

Technical Field

[0001] The present invention belongs to the technical field of breeding equipment, and particularly relates to a feeding device for sheep houses used for breeding sheep. Background Art

[0002] When breeding Shaanbei white cashmere goats, the breeding method of penning in sheep houses is mostly adopted. By feeding the sheep with forage and feed, the sheep can evenly absorb the required nutrients, which can reduce the breeding cost and shorten the slaughter cycle of the sheep. When feeding, the forage and feed are generally put into the feeding trough, and the feeding trough is generally installed on the outside of the sheep house fence. The head of the sheep passes through the gap of the fence and then eats from the feeding trough. Compared with other types of sheep, goats are more lively and active. This is not only reflected in the large amount of exercise of goats, but also when eating from the feeding trough, goats will use their mouths, heads and even four hooves to fiddle with the forage and select their favorite parts to eat, especially tender grass, grass roots, etc. It is easy to cause the forage to fall to the ground and be trampled and polluted, resulting in waste of forage.

[0003] Currently, in the prior art, a baffle or an automatic feeding mechanism is mostly used on the feeding trough to solve this problem. Among them, the baffle can block the forage from falling out of the mouth of the feeding trough when the goats fiddle with the forage, and the automatic feeding mechanism can add forage multiple times to reduce the amount of forage in the feeding trough, thereby reducing the amount of forage falling out of the feeding trough. However, the baffle can only be set on the side of the feeding trough far from the fence. Otherwise, if the height of the edge of the mouth of the feeding trough is too high, the sheep will not be able to eat the forage in the feeding trough. When the automatic feeding mechanism adds forage to the feeding trough, the forage is likely to fall on the head of the sheep, and the sheep will also be startled and swing its head, which will cause the forage to fall outside the feeding trough and cause waste. Summary of the Invention

[0004] In view of this, the present invention provides a feeding device for sheep houses used for breeding sheep to solve the deficiencies in the prior art. The present invention can reduce the forage that the sheep can fiddle with, thereby reducing the situation where the forage is fiddled by the sheep to the outside of the feeding trough.

[0005] The technical solution of the present invention is: a feeding device for sheep houses used for breeding sheep, including a feeding trough, which is horizontally arranged on the outside of the sheep house fence, and the feeding trough is connected to the sheep house fence. A supporting plate is horizontally arranged in the feeding trough and is located below the feeding trough. The supporting plate abuts against the inner wall of the feeding trough, and the supporting plate is slidably connected to the feeding trough in the vertical direction. After the forage is put into the feeding trough, the forage is located on the supporting plate. The head of the sheep passes through the sheep house fence and extends into the feeding trough to eat the forage on the supporting plate. A driving mechanism is arranged on the feeding trough, and the output end of the driving mechanism is connected to the supporting plate for driving the supporting plate to move up and down. A height detection mechanism is arranged on the feeding trough for detecting the distance value between the top of the forage on the supporting plate and the mouth of the feeding trough. When the distance value is greater than the set range, the sheep cannot eat the forage on the supporting plate, and the driving mechanism drives the supporting plate to move upward.

[0006] Preferably, the driving mechanism includes an X-shaped connecting frame, a bidirectional lead screw, and a first rotary power unit. The X-shaped connecting frame is vertically arranged directly below the pallet. The ends of the upper two arms of the X-shaped connecting frame are slidably connected to it along the length direction of the feeding trough. The bidirectional lead screw horizontally passes through the two lower arms of the X-shaped connecting frame and is in threaded fit connection with the X-shaped connecting frame. The output shaft of the first rotary power unit is connected to the bidirectional lead screw.

[0007] Preferably, two pairs of first sliding rails are horizontally arranged on the upper and lower sides of the X-shaped connecting frame. The first sliding rails are parallel to the bidirectional lead screw. Two of the first sliding rails are fixed to the bottom of the pallet, and the other two first sliding rails are fixed to the ground. First sliders are respectively arranged on the first sliding rails and are slidably connected to them. The ends of the upper and lower arms of the X-shaped connecting frame are respectively hinged to the first sliders.

[0008] Preferably, the height detection mechanism includes a cross bar and a pressure sensor arranged on the cross bar. The cross bar is horizontally arranged in the feeding trough. The two ends of the cross bar are connected to the inner walls of the feeding trough. The pressure sensor is located on the side of the cross bar close to the pallet. The distances from the upper and lower edges of the cross bar to the mouth of the feeding trough are within a set range.

[0009] Preferably, the cross bar is perpendicular to the length direction of the feeding trough. Horizontal sliding grooves are opened on the inner walls of the two sides of the feeding trough close to the ends of the cross bar. Coaxial rollers are arranged at the two ends of the cross bar. One end of the roller is connected to the cross bar, and the other end extends into the sliding groove and is slidably connected to it. A linear displacement mechanism is arranged on the feeding trough, and the output end of the linear displacement mechanism is connected to the cross bar to drive the cross bar to move back and forth.

[0010] Preferably, the linear displacement mechanism includes a screw rod and a second rotary power unit. The screw rod is horizontally arranged on the side of the feeding trough away from the sheep pen fence. The sliding groove on the side of the feeding trough away from the sheep pen fence runs through. The roller passes through the sliding groove and extends out of the feeding trough. The screw rod passes through the roller and is in threaded fit connection with it. The output shaft of the second rotary power unit is fixedly connected to the screw rod.

[0011] Preferably, a second sliding rail is horizontally and fixedly arranged on the side of the feeding trough away from the sheep pen fence. The second sliding rail is parallel to the sliding groove. A second slider is arranged on the second sliding rail and is slidably connected to it.

[0012] Preferably, a plurality of dial rods are radially and fixedly arranged at equal intervals along the length direction of the cross bar. The roller is rotatably connected to the cross bar around its circumference.

[0013] Preferably, a plurality of flexible protrusions are vertically and fixedly arranged at equal intervals along the length direction on one edge of the feeding trough. The flexible protrusions are located on the side of the feeding trough close to the sheep pen fence.

[0014] Preferably, a baffle is vertically arranged on one side of the feeding trough away from the sheepfold fence. The baffle is parallel to the length direction of the feeding trough. The lower side of the baffle is hinged to the feeding trough, and the hinge axis is parallel to the length direction of the feeding trough.

[0015] Compared with the prior art, the sheepfold feeding device for sheep breeding provided by the present invention uses the feeding trough in cooperation with the pallet, the driving mechanism and the height detection mechanism. The height detection mechanism is used to detect the distance value between the top of the forage on the pallet and the mouth of the feeding trough. The driving mechanism drives the pallet to move up and down. When the distance value is within the set range, when the sheep's head passes through the sheepfold fence and extends into the feeding trough, it can only eat the uppermost layer of forage. When the distance value is greater than the set range, the sheep cannot eat the forage on the pallet, and the driving mechanism drives the pallet to move upward, realizing that the sheep eats the forage on the pallet layer by layer, reducing the forage that the sheep can fiddle with, thereby reducing the situation that the forage is fiddled by the sheep to the outside of the feeding trough. The sheepfold feeding device of the present invention has good effect, is convenient to use, has strong practicability, and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention provides a sheepfold feeding device for sheep breeding. The following is an explanation of the present invention in combination with Figures 1 to 7 the structural schematic diagram.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the technical solution of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0025] Referring to Figure 1 , Figure 1 is the front view of the sheep house feeding device of this embodiment. As Figure 1 shown, a sheep house feeding device for sheep breeding includes a feeding trough 1, which is horizontally arranged outside the sheep house fence. The feeding trough 1 is connected to the sheep house fence. A support plate 2 is horizontally arranged in the feeding trough 1 and is located below the feeding trough 1. The support plate 2 abuts against the inner wall of the feeding trough 1. The support plate 2 is slidably connected to the feeding trough 1 in the vertical direction. After the forage is put into the feeding trough 1, the forage is located on the support plate 2. The head of the sheep passes through the sheep house fence and extends into the feeding trough 1 to eat the forage on the support plate 2. A driving mechanism is arranged on the feeding trough 1, and the output end of the driving mechanism is connected to the support plate 2 for driving the support plate 2 to move up and down. A height detection mechanism is arranged on the feeding trough 1 for detecting the distance value between the top of the forage on the support plate 2 and the mouth of the feeding trough 1. When the distance value is greater than the set range, the sheep cannot eat the forage on the support plate 2, and the driving mechanism drives the support plate 2 to move upward.

[0026] In this embodiment, by driving the support plate 2 to move up and down through the driving mechanism, the distance value between the top of the forage on the support plate 2 and the mouth of the feeding trough 1 can be adjusted. When the distance value is within the set range, when the head of the sheep passes through the sheep house fence and extends into the feeding trough 1, it can eat the topmost layer of forage. When the distance value is greater than the set range, the sheep cannot eat the forage on the support plate 2, and the driving mechanism drives the support plate 2 to move upward, realizing that the sheep eats the forage on the support plate 2 layer by layer, reducing the forage that the sheep can fiddle with, thereby reducing the situation that the forage is fiddled by the sheep to the outside of the feeding trough 1.

[0027] In this embodiment, after the forage is put into the feeding trough 1 again, the forage falls on the support plate 2. It is necessary to flatten the forage to avoid uneven forage, so as to enable the height detection mechanism to accurately judge the actual distance between the forage and the mouth of the feeding trough 1, and avoid the driving mechanism driving the support plate to move upward when the sheep can still eat the forage.

[0028] Referring to Figure 3 , Figure 3 is the A-A cross-sectional view of the sheep house feeding device of this embodiment. As Figure 3As shown in the figure, in this embodiment, a specific structure of a driving mechanism is given. The driving mechanism includes: an X-shaped connecting frame 3, a bidirectional lead screw 4, and a first rotating power unit 5. The X-shaped connecting frame 3 is vertically arranged directly below the pallet 2. The ends of the upper two arms of the X-shaped connecting frame 3 are slidably connected to it along the length direction of the feeding trough 1. The bidirectional lead screw 4 horizontally passes through the two lower arms of the X-shaped connecting frame 3, and the bidirectional lead screw 4 is in threaded fit connection with the X-shaped connecting frame 3. The output shaft of the first rotating power unit 5 is connected to the bidirectional lead screw 4.

[0029] In this embodiment, the driving mechanism can drive the bidirectional lead screw 4 to rotate by using the first rotating power unit 5, and drive the X-shaped connecting frame 3 to rotate around its hinge axis through the cooperation of the X-shaped connecting frame 3, the bidirectional lead screw 4, and the first rotating power unit 5. Thus, the height of the pallet 2 can be accurately adjusted, the thickness of the forage that the sheep can eat can be minimized, and the forage that the sheep can flick can be further reduced, thereby reducing the situation that the forage is flicked by the sheep to the outside of the feeding trough. At the same time, the X-shaped connecting frame 3 can stably support the pallet 2 and the forage placed on it, ensuring the stability of the feeding device.

[0030] Refer to Figure 4 , Figure 4 is the B-B cross-sectional view of the sheep house feeding device in this embodiment. As shown in Figure 4 As a further optimization scheme, in the embodiment of the present disclosure, two pairs of first slide rails 6 are horizontally arranged on the upper and lower sides of the X-shaped connecting frame 3. The first slide rails 6 are parallel to the bidirectional lead screw 4. Two of the first slide rails 6 are fixed to the bottom of the pallet 2, and the other two first slide rails 6 are fixed to the ground. First sliders 7 are respectively arranged on the first slide rails 6 and are slidably connected to them. The ends of the upper and lower arms of the X-shaped connecting frame 3 are respectively hinged to the first sliders 7.

[0031] In this embodiment, through the cooperation of the first slide rails 6, the first sliders 7, the X-shaped connecting frame 3, and the bidirectional lead screw 4, the stability of the X-shaped connecting frame 3 rotating around its hinge axis can be effectively improved, thereby further improving the accuracy of the up and down movement of the pallet 2 and avoiding the situation of jamming during use.

[0032] In this embodiment, a specific structure of a height detection mechanism is given. The height detection mechanism includes: a cross bar 8 and a pressure sensor arranged on the cross bar 8. The cross bar 8 is horizontally arranged in the feeding trough 1. The two ends of the cross bar 8 are connected to the inner wall of the feeding trough 1. The pressure sensor is located on the side of the cross bar 8 close to the pallet 2. The distances from the upper and lower edges of the cross bar 8 to the mouth of the feeding trough 1 are within a set range.

[0033] In this embodiment, by using the cross bar 8 and the pressure sensor in cooperation, the distance value between the top of the forage on the pallet and the mouth of the trough can be accurately judged through the extrusion of the forage on the pressure sensor, so as to improve the sensitivity of the height detection mechanism, reduce the thickness of the forage that the sheep can eat to the minimum, further reduce the forage that the sheep can fiddle with, and thus reduce the situation that the forage is fiddled by the sheep to the outside of the trough.

[0034] Refer to Figure 2 , Figure 2 which is the top view of the feeding device for the sheep house in this embodiment. As shown in Figure 2 , as a further optimization scheme, in the embodiment of the present disclosure, the cross bar 8 is perpendicular to the length direction of the trough 1. Horizontal chutes 9 are provided on the inner walls of both sides of the trough 1 near the ends of the cross bar 8. Coaxial rollers are provided at both ends of the cross bar 8. One end of the roller is connected to the cross bar 8, and the other end extends into the chute 9 and is slidably connected thereto. A linear displacement mechanism is provided on the trough 1, and the output end of the linear displacement mechanism is connected to the cross bar 8 to drive the cross bar 8 to move back and forth.

[0035] In this embodiment, through the cooperation of the chute 9 on the trough 1 and the rollers on the cross bar 8, the cross bar 8 can be moved along the length direction of the trough 1. By driving the cross bar 8 to move through the linear displacement mechanism, multiple positions of the forage in the trough can be detected, further improving the stability of the detection.

[0036] Refer to Figure 5 , Figure 4 which is the C-C cross-sectional view of the feeding device for the sheep house in this embodiment. As shown in Figure 5 , in this embodiment, a specific structure of the linear displacement mechanism is given. The linear displacement mechanism includes: a screw rod 10 and a second rotary power unit 11. The screw rod 10 is horizontally arranged on the side of the trough 1 away from the sheep house fence. The chute 9 on the side of the trough 1 away from the sheep house fence runs through. The roller passes through the chute 9 and extends out of the trough 1. The screw rod 10 passes through the roller and is threadedly connected thereto. The output shaft of the second rotary power unit 11 is fixedly connected to the screw rod 10.

[0037] In this embodiment, through the cooperation of the screw rod 10 and the second rotary power unit 11 of the linear displacement mechanism, the cross bar 8 can be accurately moved to a preset detection point, further improving the accuracy of the detection. At the same time, when the cross bar 8 moves, it can also automatically level the top layer of the forage.

[0038] As a further optimization scheme, in the embodiment of the present disclosure, a second slide rail 12 is horizontally fixed on the side of the trough 1 away from the sheep house fence. The second slide rail 12 is parallel to the chute 9. A second slider 13 is provided on the second slide rail 12 and is slidably connected thereto. The roller extends out of the trough 1 and is fixedly connected to the second slider 13. The screw rod 10 passes through the second slider 13 and is threadedly connected thereto.

[0039] In this embodiment, the stability of the movement of the cross bar 8 is improved by the second slide rail 12 and the second slider 13. This not only improves the stability of the movement of the cross bar 8, but also improves the effect of the cross bar 8 in leveling the forage.

[0040] As a further optimization scheme, in the embodiment of the present disclosure, a plurality of dial rods 14 are fixedly arranged on the cross bar 8 at equal intervals along its length direction in a radial manner, and the roller is rotatably connected to the cross bar 8 around its circumference.

[0041] In this embodiment, through the dial rods 14 on the cross bar 8, the effect of leveling the forage when the cross bar 8 moves can be effectively improved.

[0042] As a further optimization scheme, in the embodiment of the present disclosure, a plurality of flexible protrusions 15 are fixedly arranged vertically at equal intervals along the length direction on one side edge of the feeding trough 1, and the flexible protrusions 15 are located on the side of the feeding trough 1 close to the sheep house fence.

[0043] In this embodiment, after the head of the sheep passes through the sheep house fence, it needs to pass through between the flexible protrusions 15 before it can extend into the feeding trough 1. The head of the sheep will squeeze the flexible protrusions 15, so that the depth of the head of the sheep extending into the feeding trough 1 can be automatically adjusted.

[0044] Due to the differences in the body sizes of sheep, when the body size of a sheep is larger, the amplitude of the flexible protrusions 15 being squeezed and tilted to both sides is larger. Since the outer diameter of the flexible protrusions 15 gradually decreases from bottom to top, the distance that the neck of the larger sheep extends downward is small, while when the body size of the sheep is smaller, the distance that its neck can extend downward is large, so that sheep with different body sizes can all eat the forage on the same layer.

[0045] As a further optimization scheme, in the embodiment of the present disclosure, a baffle 16 is vertically arranged on the side of the feeding trough 1 away from the sheep house fence. The baffle 16 is parallel to the length direction of the feeding trough 1. The lower side of the baffle 16 is hinged to the feeding trough 1, and the hinge axis is parallel to the length direction of the feeding trough 1.

[0046] Refer to Figure 6 Figure 6 This is a schematic diagram of the baffle turning inward in this embodiment. As shown in Figure 6 In this embodiment, when the baffle 16 turns inward, it can block the forage from falling out of the feeding trough. Refer to Figure 7 Figure 7 This is a schematic diagram of the baffle turning outward in this embodiment. As shown in Figure 7 When the baffle 16 turns outward to the horizontal, it is convenient for the feeder to put the forage into the feeding trough.

[0047] The above-disclosed are only the preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.​​
