Description

Technical Field

[0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a feeding device for animal husbandry and a working method thereof. Background Art

[0002] Agricultural breeding is an important part of agriculture. Farmed cattle, sheep and other livestock need to be fed. The traditional feeding method is to place the feed directly outside the guardrail, and the livestock stick their heads out of the guardrail to eat. The disadvantage of this is that the workload is large and the feeding amount is not accurately controlled. Therefore, with the support of technology, people have designed a device to control the feeding amount according to the weight of the livestock. Several sensors are required to weigh or visually identify the body shape of the livestock, so as to control the feeding amount according to the feedback data. This method can make the feeding amount very accurate, but the cost is high, and equipment such as precision sensors are easily damaged, especially when the breeding house is disinfected. At present, there is an urgent need for a feeding device with low cost and the ability to control the feeding amount. Summary of the invention

[0003] The object of the present invention is to provide a feeding device for animal husbandry and a working method thereof, so as to solve the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A feeding device for animal husbandry comprises a tube chain conveyor, wherein a feed port and a return port are provided on the tube chain conveyor, a gate valve is installed on the return port, a feeding end of the tube chain conveyor is connected with a plurality of three-way pipes, the return end of the three-way pipes is connected with the return end of the tube chain conveyor, a feeding trough and a gravity sensing table are arranged correspondingly below the three-way pipes, a movable plate is plugged into the discharge end of the three-way pipe and is connected with the feeding trough, the gravity sensing table and the movable plate are connected by two sprocket structures, a switching frame is commonly plugged into the three-way pipes, a cylinder is installed at one end of the switching frame, and a plurality of springs are installed at the bottom of the gravity sensing table.

[0006] Furthermore, a plurality of staggered baffles and empty frames are fixed on the switching frame, and every two baffles and empty frames correspond to a three-way pipe, and the two baffles and empty frames correspond to the return end and the discharge end of the three-way pipe respectively.

[0007] Furthermore, a fixed rod is fixed on the side of the three-way pipe, a movable rod is fixed on the movable plate, the fixed rod is higher than the movable rod, and the sprocket structure is located at both ends of the fixed rod.

[0008] Furthermore, the sprocket structure includes two chain ropes and two rotating wheels, one rotating wheel bearing of the sprocket structure is connected to the fixed rod, and the other rotating wheel bearing of the sprocket structure is connected to one side of the trough. One end of a chain rope of the sprocket structure is fixed to the movable rod and then passes around the rotating wheel on the fixed rod and is fixedly connected to the sleeve. One end of another chain rope of the sprocket structure is fixed to the movable rod and then passes around the rotating wheel on the trough and is fixed to the sleeve.

[0009] Furthermore, two levers are fixed to one end of the gravity sensing platform, and the two levers are respectively inserted into two corresponding sleeves.

[0010] Furthermore, the bottom of the gravity sensing table is connected to a bottom plate through a spring, a guardrail is fixed on the bottom plate, the guardrail runs through the gravity sensing table, a limit block is fixed on the bottom plate, and the upper top surface of the limit block is higher than the rotating wheel on the trough.

[0011] Furthermore, the guardrail is enclosed in a structure with one end open, and a slope is fixed on the bottom plate of the open end of the guardrail.

[0012] A working method of a feeding device for animal husbandry, comprising the following steps:

[0013] (1) The feed is fed into the feed port of the tube chain conveyor through a screw conveyor, and the tube chain conveyor feeds the feed into each tee pipe. At this time, the baffle on the switching frame blocks the return end of the tee pipe, the empty frame overlaps with the discharge end of the tee pipe, and the movable plate blocks the discharge end of the tee pipe;

[0014] (2) After the livestock enters from the open end of the guardrail, the spring is compressed under the action of the livestock's weight, the gravity sensing plate moves downward, and the sleeve is driven downward by the lever. Under the action of the sprocket structure, the movable plate moves upward to form an opening, so that the feed falls from the opening into the trough to feed the livestock. Livestock of different weights compress the spring to different degrees, and thus the movable plate moves upward to different degrees;

[0015] (3) During feeding, the feed in the three-way pipe keeps falling, and the pipe chain conveyor keeps adding feed into each three-way pipe;

[0016] (4) After a certain period of feeding, the pneumatic cylinder moves the switching frame, and the staggered baffle and the empty frame open the return end of the three-way pipe and close the discharge end, thereby stopping feeding. The feed in the three-way pipe enters the pipe chain conveyor from the return end, opens the gate valve, and the returned feed falls back into the feed pile from the return port;

[0017] (5) After the livestock has eaten the remaining feed in the trough, it leaves and the spring rebounds, causing the movable plate to return to its original position.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention can control the amount of feed according to the weight of livestock without the need for precise sensors, has a simple structure, low cost, and is more accurate than manual feeding.

[0020] 2. The switching frame is used to switch the opening and closing of the return end and the discharge end of the three-way pipe. The baffle and the empty frame are staggered, that is, when the baffle blocks the return end of the three-way pipe, the discharge end of the three-way pipe is opened, and vice versa, thereby realizing the switching of the feed channel.

[0021] 3. The guardrail is used to limit the position of livestock and also acts as a slide bar, allowing the gravity sensing platform to slide on the guardrail to prevent the gravity sensing platform from swinging.

[0022] 4. One cylinder controls the switching of multiple three-way pipes, eliminating the need to configure a three-way valve for each three-way pipe, further reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Embodiment 1:

[0032] like Figure 1-6 As shown, a feeding device for animal husbandry comprises a tube chain conveyor 1, wherein a feed port 2 and a feed port 3 are provided on the tube chain conveyor 1, a gate valve 4 is installed on the feed port 3, a feeding end of the tube chain conveyor 1 is connected with a plurality of three-way pipes 5, a return end of the three-way pipes 5 is connected with the return end of the tube chain conveyor 1, a feeding trough 6 and a gravity sensing platform 7 are arranged correspondingly below the three-way pipes 5, a movable plate 8 is plugged into the discharge end of the three-way pipe 5 and is connected with the feeding trough 6, the gravity sensing platform 7 is connected to the movable plate 8 through two sprocket structures, a switching frame 9 is commonly plugged into the three-way pipes 5, a cylinder 10 is installed at one end of the switching frame 9, and a plurality of springs 11 are installed at the bottom of the gravity sensing platform 7. It should be noted that the tube chain conveyor 1 is usually fixed in the breeding house by a bracket, and the cylinder 10 can be fixed on the bracket. The bracket is not drawn in the drawings of the specification, but technicians in this field are clear about how to fix the tube chain conveyor 1 by the bracket and how to fix the cylinder 10 on the bracket.

[0033] A plurality of staggered baffles 12 and empty frames 23 are fixed on the switching frame 9, and every two baffles 12 and empty frames 23 correspond to one tee 5, and the two baffles 12 and empty frames 23 correspond to the return end and the discharge end of the tee 5, respectively. The tee 5 has three openings, namely the feed end, the return end, and the discharge end. Feed is fed from the feed end, the return end returns the feed to the tube chain conveyor 1, and the discharge end sends the feed to the trough 6. The switching frame 9 is used to switch the return end and the discharge end of the tee 5. The baffles 12 and the empty frames 23 are staggered, that is, when the baffle 12 blocks the return end of the tee 5, the discharge end of the tee 5 is open, and vice versa.

[0034] A fixed rod 13 is fixed on the side of the tee pipe 5 , and a movable rod 14 is fixed on the movable plate 8 . The fixed rod 13 is higher than the movable rod 14 , and the sprocket structures are located at both ends of the fixed rod 13 .

[0035] The sprocket structure includes two chains 15 and two wheels 16. The chains 15 can be steel wires, and the wheels 16 can be U-shaped wheels with grooves, or the chains 15 can be chains, and the wheels 16 can be matching gears. One wheel 16 of the sprocket structure is connected to the fixed rod 13 by a bearing, and another wheel 16 of the sprocket structure is connected to one side of the trough 6 by a bearing. One end of one chain 15 of the sprocket structure is fixed to the movable rod 14, then passes around the wheel 16 on the fixed rod 13 and is fixedly connected to a sleeve 17. One end of another chain 15 of the sprocket structure is fixed to the movable rod 14, then passes around the wheel 16 on the trough 6 and is fixed to the sleeve 17. When the sleeve 17 moves up, the movable rod 14 moves down, and the movable plate 8 blocks the discharge end of the tee pipe 5. On the contrary, when the sleeve 17 moves downward, the movable rod 14 moves upward, and there is a gap between the movable plate 8 and the inner wall of the discharge end of the three-way pipe 5 for releasing the feed. The size of the gap depends on the distance the sleeve 17 moves downward.

[0036] Two levers 18 are fixed to one end of the gravity sensing platform 7, and the two levers 18 are respectively inserted into the two corresponding sleeves 17. The lever 18 is used to drive the sleeves 17 to move up and down.

[0037] The bottom of the gravity sensing platform 7 is connected to a bottom plate 19 through a spring 11, and a guardrail 20 is fixed on the bottom plate 19. The guardrail 20 passes through the gravity sensing platform 7, and a limit block 21 is fixed on the bottom plate 19. The upper top surface of the limit block 21 is higher than the rotating wheel 16 on the trough 6. After the gravity sensing platform 7 carries the livestock, it presses down to shrink the spring 11, and the limit block 21 is used to limit the lowest height of the gravity sensing platform 7. The guardrail 20 is used for protection and limiting the position of the livestock. Secondly, it plays the role of a slide bar, allowing the gravity sensing platform 7 to slide on the guardrail 20 to prevent the gravity sensing platform 7 from swinging.

[0038] The guardrail 20 is formed into a structure with one end open, and a slope 22 is fixed on the bottom plate 19 of the open end of the guardrail 20.

[0039] Embodiment 2:

[0040] This embodiment provides a working method of a feeding device for animal husbandry, and the method steps are implemented based on Example 1.

[0041] A working method of a feeding device for animal husbandry, comprising the following steps:

[0042] (1) The feed is fed into the feed port 2 of the tube chain conveyor 1 by a screw conveyor, and the tube chain conveyor 1 feeds the feed into each tee pipe 5. At this time, the baffle 12 on the switching frame 9 blocks the return end of the tee pipe 5, the empty frame 23 overlaps with the discharge end of the tee pipe 5, and the movable plate 8 blocks the discharge end of the tee pipe 5;

[0043] (2) After the livestock enters from the open end of the guardrail 20, the spring 11 is compressed under the action of the livestock's weight, the gravity sensing plate moves downward, and the sleeve 17 is driven downward by the lever 18. Under the action of the sprocket structure, the movable plate 8 moves upward to form an opening, so that the feed falls from the opening into the trough 6 to feed the livestock. Livestock of different weights compress the spring 11 to different degrees, and thus the movable plate 8 moves upward to different degrees;

[0044] (3) During feeding, the feed in the three-way pipe 5 continues to fall, and the pipe chain conveyor 1 continuously replenishes the feed into each three-way pipe 5;

[0045] (4) After a certain period of feeding, the pneumatic cylinder 10 moves the switching frame 9, and the staggered baffle 12 and the empty frame 23 open the return end of the three-way pipe 5 and close the discharge end, thereby stopping the feeding. The feed in the three-way pipe 5 enters the pipe chain conveyor 1 from the return end, and the gate valve 4 is opened, and the returned feed falls from the feed inlet 3 back to the feed pile;

[0046] (5) After the livestock has finished eating the remaining feed in the trough 6, they exit, and the spring 11 rebounds, causing the movable plate 8 to return to its original position.

[0047] The above embodiments are only for describing the preferred implementation of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention.
