Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry equipment, in particular to a front pushing mechanism for a feeding machine. Background Art

[0002] In modern industrialized farming, livestock are raised in centralized farms, where specialized staff are responsible for feeding the animals. Because most farms have large vertical spans and long feeding troughs, feeders need to make multiple trips back and forth to complete feeding. Therefore, feed trucks are often used for feeding.

[0003] Existing feed carts, for example, Chinese invention patent publication number CN116711652A discloses a feeding device for beef cattle breeding, including a feeding cart, a feeding trough and a pushing mechanism. The pushing mechanism includes a lifting frame arranged above the feeding cart and capable of being raised and lowered, and pushing plates symmetrically arranged at both ends of the lifting frame and inclined outward from front to back. The lifting and lowering of the lifting frame are linked to the forward movement of the feeding cart through a linkage mechanism; when the feeding cart moves forward, the lifting frame descends, and the pushing plate contacts the ground, pushing the scattered feed on the ground into the feed trough to ensure the cleanliness of the ground. However, since the pushing plate protrudes from the outside of the vehicle body, the overall width of the feeding cart is relatively large, and it cannot pass through narrow sections. Utility Model Content

[0004] The purpose of the utility model is to provide a front pushing mechanism for a feeding machine, which solves the problem in the prior art that the pushing plate cannot be retracted, resulting in a relatively large overall width of the feeding vehicle.

DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0030] Example: Figure 1-3 As shown, a front pushing mechanism for a feeding machine includes: a mounting frame 1, a lifting frame 2, a movable seat 4, a lifting connecting rod 7 and a pushing plate 6. The mounting frame 1 is used to be fixed to the front end of the feeding machine frame, and the lifting frame 2 is movably set on the mounting frame 1 and is lifted and lowered by the lifting mechanism 3.

[0031] There are two movable seats 4, mounted on the lifting frame 2 via a slide rail assembly 5, allowing horizontal movement relative to the lifting frame 2. The slide rail assembly 5 includes a linear guide rail 501 horizontally arranged on the lifting frame 2 and two sliders 502 slidably connected to the linear guide rail 501. The two movable seats 4 are fixed to their corresponding sliders 502.

[0032] The two movable seats 4 are respectively connected to the mounting frame 1 through two lifting links 7. The two lifting links 7 are distributed in a V shape, one end of the two lifting links 7 is hinged at the same position of the mounting frame 1, and the other end is hinged on the movable seat 4.

[0033] There are two pusher plates 6 , which are arranged on the front side of the mounting frame 1 . The end of the lifting frame 2 is slidably connected to the pusher plate 6 , and the movable seat 4 is connected to the end of the pusher plate 6 through the rotating shaft 8 .

[0034] A vertical sliding rod 9 is provided at the end of the lifting frame 2, and a sliding groove 603 extending along the length direction is provided on the push plate 6. The sliding rod 9 is inserted into the sliding groove 603. A roller 10 is provided at the lower end of the sliding rod 9, and a rolling groove 604 for mounting the roller 10 is provided on the back of the push plate 6.

[0035] When the lifting frame 2 moves up and down under the drive of the lifting mechanism 3, the two lifting links 7 swing in opposite directions, and the angle between the two lifting links 7 increases or decreases. When the lifting links 7 swing, they drive the movable seat 4 to move left or right. Since the movable seat 4 is connected to the push plate 6 through the rotating shaft 8, the push plate 6 moves left or right with the movable seat 4, and the sliding rod 9 slides in the sliding groove 603, causing the push plate 6 to be pushed outward or retracted inward. At the same time, the lifting frame 2 drives the push plate 6 to rise or fall.

[0036] like Figure 4 As shown, the rotating shaft 8 is located in front of the sliding rod 9, and the line connecting the two forms an angle a with the moving path of the movable seat 4. Since the position of the sliding rod 9 relative to the lifting frame 2 remains unchanged, the vertical distance from the rotating shaft 8 to the lifting frame 2 also remains unchanged. Therefore, the size of the angle a increases as the movable seat 4 moves toward the end of the lifting frame 2.

[0037] In the initial state, the distance between the rotating shaft 8 and the sliding rod 9 is the farthest, and the angle a is the smallest at this time. Specifically, the angle a is 5-10°; in the expanded state, the distance between the lower rotating shaft 8 and the sliding rod 9 is the smallest, and the angle a is the largest at this time. Specifically, the angle a is 30-45°.

[0038] like Figure 5As shown, when the lifting frame 2 descends to its lowest point, the movable seat 4 moves to the left and right ends of the lifting frame 2. At this point, the pusher plate 6 descends to its lowest position and extends outward. In this state, the angle a formed by the pusher plate 6 and the lifting frame 2 is maximized, and the outer end of the pusher plate 6 swings rearward to its maximum position, causing the pusher plate 6 to be tilted relative to the feeder's forward direction. As the feeder advances, the pusher plate 6 pushes the feed to the sides, pushing the feed into the feed troughs on both sides.

[0039] The sliding rod 9 is fixedly connected with a connecting plate 11, and a vertical limit stop rod 12 is provided on the connecting plate 11. The limit stop rod 12 is located at the rear side of the push plate 6. During the pushing process, the limit stop rod 12 is against the rear side of the push plate 6 for supporting the push plate 6.

[0040] like Figure 2 As shown, the push plate 6 includes an upper push plate 601 and a lower push plate 602 connected to the lower portion of the upper push plate 601. The lifting frame 2 and the movable seat 4 are connected to the upper push plate 601. The sliding groove 603 and the rolling groove 604 are both provided on the upper push plate 601. The lower push plate 602 is a flexible plate and is fixed to the upper push plate 601 by bolts, which facilitates replacement.

[0041] like Figure 2 and Figure 3 As shown, the lifting mechanism 3 includes a screw rod 301 , a nut seat 302 arranged on the screw rod 301 and a motor 303 driving the screw rod 301 to rotate. The screw rod 301 is vertically arranged on the mounting frame 1 , and the nut seat 302 is connected to the lifting frame 2 .

[0042] Guide rods 13 are provided on both sides of the screw rod 301 , and the lifting frame 2 is slidably mounted on the guide rods 13 .

[0043] An upper mounting plate 304 and a lower mounting plate 305 are respectively provided on the upper and lower sides of the lifting frame 2. A support rod 306 is connected between the upper mounting plate 304 and the lower mounting plate 305. The upper mounting plate 304 is fixed on the nut seat 302, and the lower mounting plate 305 is slidably installed on the guide rod 13. A spring 307 is provided on the support rod 306, and the upper and lower ends of the spring 307 are respectively against the upper mounting plate 304 and the lifting frame 2.

[0044] When the motor rotates forward or reverse, the nut 302 drives the lifting frame 2 up and down under the drive of the screw rod 301. When moving downward, the upper mounting plate 304 moves downward following the nut 302. The upper mounting plate 304 applies pressure to the spring 307, causing the spring 307 to press the lifting frame 2 downward, thus achieving the descent of the lifting frame 2. When the push plate 6 contacts the ground or an obstacle and cannot continue to descend, the upper mounting plate 304 continues to descend following the nut 302, causing the spring 307 to be compressed until the motor stops rotating, thus acting as a buffer. When moving upward, the upper mounting plate 304 moves upward following the nut 302, and the lower mounting plate 305 supports the bottom of the lifting frame 2, driving the lifting frame 2 to rise.
