Description

Technical Field

[0001] The present invention belongs to the technical field of livestock breeding feeding, and specifically relates to a salt supplement device and method for livestock breeding. Background Art

[0002] In livestock breeding, salt supplementation is particularly important because salt is crucial for the growth, metabolism, and health of animals. Especially for ruminants such as cattle and sheep, they need sufficient minerals such as sodium and chlorine, so salt addition devices are required during breeding to supplement salt.

[0003] For example, the invention application with the publication number CN116406626A in the technical field of livestock breeding technology discloses a livestock salt supplement device for livestock breeding, including: a livestock fence, a controller, a salt supply system, a solar power supply system, and a monitoring system; the controller is arranged outside the livestock fence; the salt supply system is installed on the top of the controller; the solar power supply system is arranged on the upper left side of the salt supply system, and the solar power supply system is electrically connected to the controller; the monitoring system is arranged on the upper right rear of the salt supply system, and the monitoring system is electrically connected to the controller.

[0004] Combined with the above case and the actual situation, we found the following problems: There are usually two ways to supplement salt during breeding, either directly putting salt bricks at fixed positions in the feed trough or adding appropriate amounts of crushed salt bricks to the feed for feeding. When putting salt bricks into the feed, since different-sized livestock need different amounts of salt supplementation, when mixing crushed salt bricks into the feed, it is necessary to mix and proportion one feed trough after another, which is troublesome to operate. Moreover, in the above case, a large number of electrical appliances and sensors are required, resulting in a high cost. Summary of the Invention

[0005] The purpose of the present invention is to provide a salt supplement device and method for livestock breeding to solve the above problems of the prior art.

The middle mounting block is threadedly connected to the threaded rod, and the upper and lower groups of mounting blocks are slidably connected to the corresponding limit rods.

[0012] In the technical solution of the present invention, the control pipe is communicated with the conveying pipe. The upper and lower ports of the hose are respectively communicated with the upper and lower openings of the control pipe. Openings for the hose to pass through are provided in the middle of both the upper rotating plate and the lower fixed plate.

[0013] In the technical solution of the present invention, a limiting ring is fixed to the top of the upper rotating plate. The top end of the limiting ring is embedded in the inner top surface of the control pipe and the limiting ring is rotatably connected to the control pipe. The movable holes are annularly distributed and are radially arranged. The clamping rod is arranged in the corresponding movable hole and the two are slidably connected. A notch is provided on the left side wall of the control pipe, and the tooth part passes through the notch and meshes with the toothed plate.

[0014] In the technical solution of the present invention, the clamping block grooves are arranged around the corresponding openings on the top surface of the lower fixed plate.

[0016] In the technical solution of the present invention, a reset component for driving the movable bottom groove to reset is provided in the groove body, and the reset component includes a pressing plate arranged horizontally in a concave shape above the groove body and a plurality of pressing structures regularly arranged below the pressing plate, and the pressing structure includes two groups of connecting rods, a plurality of horizontal rods fixed parallel to each other between two connecting rods in the same group, a pressure rod fixed below the middle of the horizontal rod, and a plurality of blocking mechanisms corresponding one to one to the plurality of horizontal rods.

[0017] In the technical solution of the present invention, a plurality of push rods corresponding to the plurality of pressing structures are fixed on the top surface of the movable bottom groove, the blocking mechanism includes a push plate and an insertion rod fixed to the middle part of the outer wall of the push plate, the push plate is a semicircular ring plate and the inner diameter of the middle part gradually decreases from top to bottom, the bottom diameter of the two push plates at the same height is smaller than the diameter of the top surface of the push rod, a plurality of insertion rod grooves corresponding to the plurality of insertion rods are provided on the groove wall of the slide groove, an inclined portion is provided on the rod wall, the inclined portion is higher on the outer side and lower on the inner side, the bottom end of the pressure rod is in contact with the inclined portion and the contact surfaces of the two are in contact, and a spring is provided between the insertion rod groove and the insertion rod.

[0018] On the other hand, the present invention also provides a method for replenishing salt for animal husbandry, using the above-mentioned salt replenishing device for animal husbandry, comprising the following steps:

[0019] S1. Put a proper amount of feed into the trough. Under the action of the gravity of the feed, the movable bottom trough slides down and compresses the airbag, so that the gas in the airbag enters the air cavity through the trachea and pushes the piston head forward. At the same time, the sliding rod will open the plate until it is fully opened and descends to the bottom of the plate and is supported;

[0020] S2. When the piston head moves forward, the tooth plate pushes the upper rotating plate to rotate counterclockwise through the teeth, and the movable holes on the upper rotating plate drive all movable plates to translate counterclockwise along the block slots through the clamping rod, so that the gaps between the movable plates are opened;

[0021] S3. After the movable plate is opened, the electric motor is started to drive the threaded rod to rotate, so that the storage box slides left and right along the limit rod. At this time, the salt brick fragments can fall evenly from the control tube to the tank below;

[0022] S4. When the movable bottom tank of the breeding farm needs to be reset due to the breeding cycle, press the pressing plate to push the connecting rod downward to drive the horizontal rod and the resisting rod, push the inserting rod outward through the inclined surface, and then separate all the resisting plates. At this time, the airbag can push the movable bottom tank upward to reset, and drive the piston head to move backward, so that the gap between the movable plates is closed again.

[0023] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, by setting the feeding trough assembly and the feeding component, when an appropriate amount of feed is put into the trough body, the movable bottom tank slides down and compresses the airbag, so that the gas in the airbag enters the air chamber through the air pipe and pushes the piston head forward. The toothed plate pushes the upper rotating plate to rotate counterclockwise through the toothed part. The movable hole on the upper rotating plate drives all the movable plates to translate counterclockwise along the block groove through the clamping rod, so that a suitable gap is opened between the movable plates, thereby controlling the diameter of the hose to adapt to the feed input amount, ensuring that the amount of salt bricks put in is appropriate. At the same time, the device has only one motor, with lower cost and more practicality.

[0025] 2. In the present invention, by setting the reset component, when the movable bottom tank of the breeding farm needs to be reset due to the breeding cycle, press the pressing plate to push the connecting rod downward to drive the horizontal rod and the resisting rod, push the inserting rod outward through the inclined surface, and then separate all the resisting plates. At this time, the airbag can be unfolded again to push the movable bottom tank upward to reset, and drive the piston head to move backward, so that the gap between the movable plates is closed again, which is convenient for subsequent use.

[0041] The following combines the drawings to describe the detailed implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0042] Unless otherwise clearly stated, throughout the specification, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0043] Refer to Figures 1-11 As shown, this embodiment provides a technical solution:

[0044] A salt supplement device and method for livestock farming, including a feeding trough assembly 1 for placing feed. The feeding trough assembly 1 includes a trough body 11 and a movable bottom trough 13 slidably connected at the bottom inside the trough body 11. Air bags 14 are symmetrically arranged left and right between the inner bottom surface of the trough body 11 and the outer bottom surface of the movable bottom trough 13. When feeding is put into the trough body 11, the movable bottom trough 13 will be pressed downward under the action of gravity, and at the same time, the air bags 14 will be compressed. It should be noted that the air bags 14 are elastic air bags, such as air spring rubber air bags. After being compressed, they can automatically recover when the pressure is released. This is prior art and will not be elaborated here;

[0045] Above the trough body 11, there is a feeding component 2. The feeding component 2 includes a storage box 21, a driving structure 22 for driving the storage box 21 to move left and right, and a transmission structure 24 communicated with the storage box 21 through a conveying pipe 23. The salt brick is crushed and then put into the storage box 21. The feeding port of the storage box 21 is on the right side, not shown in the figure. A control valve is provided on the conveying pipe 23, not shown in the figure. The feeding port and the control valve are both prior art and will not be elaborated here;

[0046] The transmission structure 24 includes a control pipe 241, a flexible pipe 242 adhesively fixed inside the control pipe 241, a control mechanism 243 for controlling the diameter of the flexible pipe 242, and a pushing mechanism 244 for driving the control mechanism 243. By cooperating the control mechanism 243 with the pushing mechanism 244, the diameter of the flexible pipe 242 is controlled according to the amount of feed put in, so as to control the feeding amount of the salt brick fragments and ensure an appropriate salt brick feeding amount;

[0047] The control mechanism 243 includes an upper rotating plate 2431, a lower fixed plate 2432 bolted to the inner wall of the control pipe 241, and several movable plates 2435 regularly distributed between the upper rotating plate 2431 and the lower fixed plate 2432. A tooth part 2439 integrally formed at the left side edge of the upper rotating plate 2431. A clamping rod 2436 is welded and fixed in the middle at the outer edge of the top surface of the movable plate 2435, and a clamping block 2437 is welded and fixed in the middle at the outer edge of the bottom surface of the movable plate 2435. The upper rotating plate 2431 is provided with several movable holes 2434 corresponding to the several clamping rods 2436 one by one, and the lower fixed plate 2432 is provided with several clamping block grooves 2438 corresponding to the several clamping blocks 2437 one by one. When the upper rotating plate 2431 rotates counterclockwise, the movable holes 2434 on the upper rotating plate 2431 drive all the movable plates 2435 to translate counterclockwise along the clamping block grooves 2438 through the clamping rods 2436, so that the gap between the movable plates 2435 is opened to control the diameter of the flexible pipe 242;

[0048] The driving mechanism 244 includes a fixed cylinder 2441 communicated with the airbag 14 through a trachea 15, a piston head 2443 slidably connected in the fixed cylinder 2441, and a toothed plate 2444 fixedly connected to the front end of the piston head 2443 by welding. When the piston head 2443 moves forward, the toothed plate 2444 pushes the upper rotating plate 2431 to rotate counterclockwise through the tooth portion 2439.

[0049] In addition, as Figure 1 shown, a chute 111 for the movable bottom groove 13 to slide up and down is provided on the upper half of the inner side wall of the trough body 11. The movable bottom groove 13 is completely arranged in the trough body 11 to prevent feed leakage. Support rods 12 are welded to the left and right ends of the rear side of the trough body 11, and an extension plate 121 is welded to the front side of the top of the support rods 12.

[0050] Furthermore, as Figure 2 shown, the driving structure 22 includes an electric motor 221, a threaded rod 222 coaxially fixed to the output shaft of the electric motor 221, and two upper and lower parallel limiting rods 223. The electric motor 221 is fixed to the left side wall of the left extension plate 121 by bolts. The threaded rod 222 passes through the left extension plate 121 and is rotatably connected to the right extension plate 121. The two ends of the limiting rod 223 are welded and fixed between the two extension plates 121. A plurality of mounting blocks 224 distributed in a matrix are welded and fixed to the rear side wall of the storage box 21. The middle mounting block 224 is threadedly connected to the threaded rod 222. The electric motor 221 drives the storage box 21 to slide left and right by driving the threaded rod 222. The upper and lower two groups of mounting blocks 224 are slidably connected to the corresponding limiting rods 223, and the storage box 21 is limited by the limiting rods 223 to prevent the storage box 21 from rotating synchronously with the threaded rod 222.

[0051] Specifically, as Figures 3-5 shown, the control pipe 241 is communicated with the conveying pipe 23. The upper and lower ports of the flexible pipe 242 are respectively communicated with the upper and lower openings of the control pipe 241. Openings for the flexible pipe 242 to pass through are provided in the middle parts of the upper rotating plate 2431 and the lower fixing plate 2432. The salt brick enters the top pipe orifice of the control pipe 241 through the conveying pipe 23, then enters the flexible pipe 242, and finally is sent out from the bottom pipe orifice of the control pipe 241.

[0052] In addition, as shown in the figure, a limiting ring 2433 is welded to the top of the upper rotating plate 2431. The top end of the limiting ring 2433 is embedded in the inner top surface of the control pipe 241, and the limiting ring 2433 is rotatably connected to the control pipe 241. By providing the limiting ring 2433, the upper rotating plate 2431 is supported, and at the same time, the rotation of the upper rotating plate 2431 is not affected. The moving holes 2434 are annularly distributed and are radially arranged. The clamping rods 2436 are arranged in the corresponding moving holes 2434 and are slidably connected to each other. When the upper rotating plate 2431 rotates counterclockwise, the moving holes 2434 will drive the clamping rods 2436 to move outward synchronously. A notch is provided on the left side wall of the control pipe 241, and the tooth part 2439 passes through the notch and meshes with the tooth plate 2444.

[0053] Furthermore, the clamping block grooves 2438 are arranged around the corresponding openings on the top surface of the lower fixing plate 2432. The clamping blocks 2437 are slidably connected in the corresponding clamping block grooves 2438. The hose 242 passes through the middle parts of several moving plates 2435. When the upper rotating plate 2431 rotates counterclockwise, the moving plates 2435 are unfolded under the combined action of the clamping rods 2436 and the clamping blocks 2437, so that the gaps between all the moving plates 2435 become larger, and thus the hose 242 can be unfolded to expand the pipe diameter.

[0054] Specifically, the fixed cylinder 2441 is welded and fixed to the left side of the control pipe 241 through the mounting plate 2442. An air chamber 2445 communicating with the air pipe 15 is provided in the fixed cylinder 2441. The piston head 2443 is slidably connected in the air chamber 2445 and their sizes are adapted to each other. When the airbag 14 is compressed, the gas in the airbag 14 enters the air chamber 2445 through the air pipe 15 and pushes the piston head 2443 forward, thereby driving the upper rotating plate 2431 to rotate.

[0055] In addition, as Figures 6-11 shown, a reset assembly 3 for driving the movable bottom groove 13 to reset is provided in the groove body 11. By providing the reset assembly 3, when the livestock in the place are replaced due to the breeding cycle, the movable bottom groove 13 can be reset, avoiding the equipment being unable to be used after replacing livestock of different sizes.

[0056] The reset assembly 3 includes a pressing plate 31 horizontally arranged in a concave shape above the groove body 11 and a plurality of pressing structures 32 regularly arranged below the pressing plate 31. The pressing structure 32 includes two groups of connecting rods 321, a plurality of horizontal rods 322 welded and fixed in parallel between the two connecting rods 321 in the same group, a pressing rod 323 welded and fixed below the middle of the horizontal rod 322, and a plurality of blocking mechanisms 324 corresponding to the plurality of horizontal rods 322 one by one. During reset, pressing the pressing plate 31 can drive the blocking mechanism 324 to open and reset through the connecting rods 321 and the horizontal rods 322.

[0057] Furthermore, a plurality of push rods 131 corresponding to the plurality of pressing structures 32 are welded and fixed on the top surface of the movable bottom groove 13, and the blocking mechanism 324 includes a push plate 3241 and an insertion rod 3242 welded and fixed to the middle part of the outer wall of the push plate 3241. A plurality of insertion rod grooves 112 corresponding to the plurality of insertion rods 3242 are provided on the groove wall of the slide groove 111, and an inclined portion 3242a is provided on the rod wall of the insertion rod 3242. The inclined portion 3242a is higher toward the outside and lower toward the inside. The bottom end of the pressure rod 323 abuts against the inclined portion 3242a and the contact surfaces of the two are in contact. When the horizontal rod 322 drives all the pressure rods 323 to be pressed downward, the corresponding insertion rod 3242 will be pushed outward through the corresponding inclined portion 3242a, thereby driving all the push plates 3241 to move outward and separate, so that the push rod 131 can slide upward and reset synchronously with the movable bottom groove 13 under the push of the deployment of the airbag 14.

[0058] Furthermore, the plate 3241 is a semicircular ring plate and the inner diameter of the middle part gradually decreases from top to bottom, so that the plate 3241 is pushed outward when the push rod 131 is pressed down. The bottom diameter of the two plates 3241 at the same height is smaller than the top diameter of the push rod 131, so that after the push rod 131 pushes away the two upper plates 3241, the closed plate 3241 blocks the push rod 131 again, so as to avoid the elastic force of the airbag 14 pushing the push rod 131 up again when the livestock is eating the feed, which causes the subsequent hose 242 to become smaller again, resulting in uneven addition of salt bricks and affecting the health of the livestock.

[0059] A spring 3243 is provided between the insertion rod slot 112 and the insertion rod 3242 , and the elastic force of the spring 3243 gives a push toward the middle to the two abutment plates 3241 at the same height, ensuring that the two abutment plates 3241 at the same height can be closed again after being opened.

[0060] The present invention also provides a method for replenishing salt for animal husbandry, using the above-mentioned salt replenishing device for animal husbandry, comprising the following steps:

[0061] S1. Put a proper amount of feed into the tank body 11. Under the action of the gravity of the feed, the movable bottom tank 13 slides down and compresses the airbag 14, so that the gas in the airbag 14 enters the air cavity 2445 through the air pipe 15 and pushes the piston head 2443 forward. At the same time, the sliding support rod 131 will open the support plate 3241 until it is fully opened and descends to the bottom of the support plate 3241 and is supported;

[0062] S2. When the piston head 2443 moves forward, the tooth plate 2444 pushes the upper rotating plate 2431 to rotate counterclockwise through the tooth portion 2439, and the movable hole 2434 on the upper rotating plate 2431 drives all movable plates 2435 to translate counterclockwise along the block slot 2438 through the clamping rod 2436, so that the gaps between the movable plates 2435 are opened. As the livestock grows, more feed is added, and the gaps between the movable plates 2435 will increase;

[0063] S3. After the movable plate 2435 is opened, start the electric motor 221 to drive the threaded rod 222 to rotate, so that the storage box 21 slides left and right along the limiting rod 223. At this time, the salt brick fragments can uniformly fall from the control pipe 241 into the lower trough 11;

[0064] S4. When the movable bottom trough 13 needs to be reset due to the breeding cycle of the breeding site, press the pressing plate 31 to make the connecting rod 321 push the horizontal rod 322 and the resisting rod 131 downward. Through the inclined surface portion 3242a, push the insertion rod 3242 outward, so that all the resisting plates 3241 are separated. At this time, the airbag 14 can be re-expanded to push the movable bottom trough 13 to move upward and reset, and drive the piston head 2443 to move backward, so that the gap between the movable plates 2435 is closed again.

[0065] The foregoing description of specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that, according to the above teachings, many changes and variations are possible.

A method for replenishing salt for animal husbandry, using the salt replenishing device for animal husbandry according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Put a proper amount of feed into the trough body (11). Under the action of the gravity of the feed, the movable bottom trough (13) slides down and compresses the airbag (14), so that the gas in the airbag (14) enters the air cavity (2445) through the air pipe (15) and pushes the piston head (2443) forward. At the same time, the sliding support rod (131) will open the support plate (3241) until it is fully opened and descends to the bottom of the support plate (3241) to be supported; S2. When the piston head (2443) moves forward, the tooth plate (2444) pushes the upper rotating plate (2431) to rotate counterclockwise through the tooth portion (2439), and the movable hole (2434) on the upper rotating plate (2431) drives all movable plates (2435) to translate counterclockwise along the block groove (2438) through the clamping rod (2436), so that the gaps between the movable plates (2435) are opened; S3, after the movable plate (2435) is opened, the electric motor (221) is started to drive the threaded rod (222) to rotate, so that the storage box (21) slides left and right along the limit rod (223), and the salt brick fragments can fall evenly from the control tube (241) to the tank body (11) below; S4.
