Description

Technical Field

[0001] The utility model relates to the technical field of material troughs, and more specifically to a material trough with a feeding function. Background Art

[0002] In animal husbandry, feed troughs are key equipment that are essential for ensuring the health of animals and the effective use of feed. However, there are some obvious technical challenges in the current feed troughs for sheep. First, many existing feed troughs rely on gravity sensors to control the delivery of feed. This sensor is not only expensive, but also increases the manufacturing cost of the feed trough, which is a considerable economic burden for farmers. Moreover, due to its complex mechanical structure and electronic components, the gravity sensor is easily affected by environmental factors such as humidity and temperature, resulting in frequent failures, which affects the stability and reliability of the feed trough. Secondly, gravity sensors often have accuracy problems in feed delivery control. Since the amount of food and eating speed of each sheep in the flock are different, it is difficult for traditional gravity sensors to accurately control the amount of feed delivered, which may lead to feed waste or nutritional imbalance in the flock. In addition, when the gravity sensor fails, the automatic feeding function of the feed trough will fail, and manual intervention is required for repair and adjustment, which not only increases the labor intensity of the breeder, but also may affect the normal feeding and management of the flock.

[0003] Therefore, developing a low-cost, highly reliable feeding trough that can accurately control the amount of feed put in will bring many conveniences to the farm and is a technical problem that needs to be solved. Utility Model Content

[0004] To this end, it is necessary to provide a feed trough with a feeding function to solve the problems of high feeding costs and high failure rates caused by the current feeding troughs that rely on gravity sensors to control feeding, as well as the resulting failure of the automatic feeding function and difficulty in normal feeding of feed.

[0005] To achieve the above-mentioned purpose, the utility model provides a material trough with a feeding function, comprising a bottom plate; a storage hopper is fixedly connected to the top of the bottom plate through a group of fixed columns; a conveying pipe is connected to the bottom of the storage hopper; a feeding trough is fixedly connected to the top of the bottom plate; a pressure plate is slidably connected to the inner wall of the feeding trough; a first elastic telescopic rod is fixedly connected to the bottom of the storage hopper; a first connecting rod is fixedly connected to the telescopic end of the first elastic telescopic rod; the bottom of the first connecting rod is fixedly connected to the pressure plate; a cylinder is fixedly connected to the inner bottom wall of the storage hopper; a group of first through grooves are opened on the cylinder; a closing piece is provided on the pressure plate; the closing piece is used to close a group of first through grooves.

[0006] In some preferred embodiments, the closure member includes a first sliding groove; a group of the first sliding grooves are respectively opened in a group of first through grooves; a group of the first sliding grooves are all slidably connected with a closing plate; a group of the closing plates are connected by a cross plate; the bottom of the cross plate is connected to the top of the pressing plate by a second connecting rod. These embodiments can accurately control the amount of feed put in. Through the sliding of the pressing plate in the feeding trough, in conjunction with the linkage of the second connecting rod and the cross plate, the sliding distance of the closing plate in the first sliding groove can be accurately controlled to achieve accurate closure or opening of the first through groove, ensuring that the feed is put in according to the required amount. Secondly, this design improves the stability and reliability of the equipment. Compared with the traditional gravity sensor control method, this mechanical closure member structure is simpler, less susceptible to the influence of the external environment, reduces the failure rate, and improves the stability and reliability of the equipment. Finally, this design is also easy to clean and maintain. Since the closure member and the pressing plate and other components can be disassembled and cleaned, it is easy to clean the residual feed and dirt in the trough, keep the equipment clean and hygienic, and also facilitate the maintenance and maintenance of the equipment.

[0007] In some preferred embodiments, a motor is provided in the cylinder; a first rotating rod is provided at the output end of the motor; the top of the first rotating rod is rotatably connected to the top wall of the cylinder and penetrates the top of the cylinder; a support rod is fixedly connected to the top of the first rotating rod; and stirring plates are fixedly connected to both ends of the bottom of the support rod. Such a design can effectively prevent the feed from caking or depositing in the storage hopper. The motor drives the first rotating rod and the support rod to rotate, thereby driving the stirring plate to rotate in the cylinder to evenly stir the feed, ensuring that the feed remains loose when it flows out of the first through groove, thereby improving the fluidity and utilization rate of the feed. Secondly, the stirring function can ensure the freshness and nutritional value of the feed. Through regular or continuous stirring, the deterioration or nutrient loss caused by long-term storage of the feed in the storage hopper can be avoided, ensuring that the sheep can take fresh and nutritious feed. At the same time, this design also improves the automation level of the feeding trough. The motor-driven stirring system can set different stirring frequencies and times as needed to achieve automatic stirring and feeding, reduce the tediousness and labor intensity of manual operation, and improve feeding efficiency.

[0008] In some preferred embodiments, a second through groove is provided at the bottom of the stirring plate; a second elastic telescopic rod is fixedly connected to the groove wall of the second through groove; and a trapezoidal block is fixedly connected to the telescopic end of the second elastic telescopic rod. In these embodiments, the trapezoidal block can generate additional vibration or agitation during the stirring process under the action of the second elastic telescopic rod, which helps to further break up and mix the feed, especially for more viscous or easy to agglomerate feed, which can improve the stirring efficiency and ensure uniform mixing of the feed. At the same time, the design of the trapezoidal block can increase the contact area between the stirring plate and the feed, especially in the edge and corner areas of the stirring plate. These areas are often prone to residual feed, and the vibration of the trapezoidal block can help remove these residues, keep the stirring tank clean, and avoid feed waste and pollution. In addition, by adjusting the length and elasticity of the second elastic telescopic rod, it can adapt to different types and states of feed. For example, for harder feed, the elasticity of the second elastic telescopic rod can be increased to make it produce greater vibration; for softer feed, the elasticity can be reduced to avoid excessive stirring.

[0009] In some preferred embodiments, a second sliding groove is provided on the second connecting rod; a pressing block is slidably connected in the second sliding groove, and the bottom of the pressing block is fixed to the wall of the second sliding groove through a spring; a sliding rod is fixed to the pressing block, and the sliding rod is slidably connected in the second sliding groove; a group of cross rods are fixed to the sliding rod. Through the linkage of the pressing block and the sliding rod, the breeder can adjust the position of the pressing plate more flexibly. When it is necessary to quickly adjust the amount of feed, just press the pressing block, and the elastic force of the spring can push the sliding rod and the cross rod to move, thereby driving the pressing plate to slide in the feeding trough to achieve rapid feeding. In addition, the design of the sliding rod and the cross rod makes the movement of the pressing plate more stable and accurate. The breeder can fine-tune the position of the sliding rod according to the feeding situation of the flock, thereby avoiding waste of feed and ensuring that the flock obtains sufficient nutrition. This design achieves precise control of the position of the pressing plate through a simple mechanical structure, without the need for a complex electronic control system, reducing the manufacturing cost of the equipment, and simplifying the maintenance and maintenance of the equipment.

[0010] In some preferred embodiments, a group of fixing holes are provided on the bottom plate. Such a design enables the trough to be more firmly installed on the breeding ground, effectively preventing the trough from shifting or tipping over during use, and ensuring the smooth progress of the breeding work. Secondly, through the fixing holes, the trough can be conveniently connected to the ground or other fixed structures, improving the stability and safety of the equipment. This is especially important for large-scale breeding farms, which can ensure that the trough remains stable when carrying a large amount of feed. Finally, the provision of the fixing holes also facilitates the transportation and installation of the equipment, reduces the labor intensity of the breeder, and improves work efficiency.

[0011] In some other preferred embodiments, the trapezoidal block is tilted toward the delivery pipe. The tilted trapezoidal block can better guide the feed to flow toward the delivery pipe, ensuring that the feed can flow out of the storage hopper smoothly, avoiding the retention or accumulation of feed in the storage hopper, and improving the utilization rate of the feed. Secondly, the tilt angle of the trapezoidal block can be adjusted according to actual needs to adapt to feed of different types and states. Such a design makes the feeding trough more adaptable and flexible, and can better meet the different needs in the feeding process.

[0012] In some other preferred embodiments, the inner bottom wall of the storage hopper is an inclined surface. The inclined inner bottom wall helps the material flow more smoothly to the conveying pipe under the action of gravity. Especially when dealing with materials with poor fluidity or easy to agglomerate, the inclined surface can significantly reduce blockage and improve material discharge efficiency. Since the material flow is smoother, the hopper can be emptied faster, thereby shortening the waiting time and improving the overall production efficiency. Smooth material flow avoids additional energy consumption and equipment wear caused by blockage, prolongs the service life of the equipment, and reduces maintenance costs.

[0013] Different from the prior art, the above technical solution significantly improves the efficiency and stability of feeding through innovative design. First, it abandons the complex way of traditional feeding troughs relying on gravity sensors to control feeding, and instead adopts a mechanical pressure plate and a first elastic telescopic rod combination. When the feed is delivered to the pressure plate through the conveying pipe, the pressure plate will naturally press down. When the contraction force of the first elastic telescopic rod is insufficient, the pressure plate will touch the bottom of the feeding trough. At this time, the closure will close a group of first through slots and stop feeding. As the flock eats, the elastic force of the first elastic telescopic rod will push the pressure plate up, further open the closure to continue feeding. This design not only simplifies the structure and reduces costs, but also reduces the failure rate and ensures smooth feeding of feed. Secondly, the utility model adds a trapezoidal block to the stirring plate. Through the connection between the second elastic telescopic rod and the second through slot, the trapezoidal block can generate impact when the stirring plate rotates, effectively preventing the feed from being blocked in the first through slot. This design not only improves the anti-blocking effect, but also can quickly solve the blockage problem, ensuring the continuity and stability of feed supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figures 1 to 5As shown, a material trough with a feeding function described in an embodiment of the utility model comprises a bottom plate 1; a storage hopper 2 is fixedly connected to the top of the bottom plate 1 through a group of fixing columns; a conveying pipe 3 is connected to the bottom of the storage hopper 2; a feeding trough 4 is fixedly connected to the top of the bottom plate 1; a pressing plate 5 is slidably connected to the inner wall of the feeding trough 4; a first elastic telescopic rod 6 is fixedly connected to the bottom of the storage hopper 2; a first connecting rod 7 is fixedly connected to the telescopic end of the first elastic telescopic rod 6; the bottom of the first connecting rod 7 is fixedly connected to the pressing plate 5; a cylinder 8 is fixedly connected to the inner bottom wall of the storage hopper 2; a group of first through grooves 9 are opened on the cylinder 8; a closing piece is provided on the pressing plate 5; the closing piece is used to When the feed is fed to the feeding trough 4, the pressing plate 5 is pressed down, and when the contraction force of the first elastic telescopic rod 6 is insufficient, the pressing plate 5 reaches the bottom of the feeding trough 4, and the closing member is driven to close the first through-grooves 9. After the sheep have eaten to a certain extent, the elastic force of the first elastic telescopic rod 6 will move the pressing plate 5 up to a certain position, and the closing member can be controlled to open and continue feeding, thereby solving the problem that the current feeding trough needs a gravity sensor to control the feeding, and the sensor is expensive, and the sensor is prone to various faults, resulting in failure of the automatic feeding function and affecting the normal feeding of the feed.

[0031] The closing member includes a first sliding groove 10; a group of the first sliding grooves 10 are respectively opened in a group of first through grooves 9; a group of the first sliding grooves 10 are all slidably connected with a closing plate 11; a group of the closing plates 11 are connected through a cross plate 12; the bottom of the cross plate 12 is connected to the top of the pressing plate 5 through a second connecting rod 13. During operation, since the closing plates 11 are connected to each other through the cross plate 12, and the cross plate 12 is connected to the pressing plate 5 through the second connecting rod 13, the feed reaches the pressing plate 5 under the transportation of the conveying pipe 3 and presses the pressing plate 5 downward. When the contraction force of the first elastic telescopic rod 6 is insufficient, the pressing plate 5 reaches the bottom of the feeding trough 4, and at the same time drives the cross plate 12 to move downward through the second connecting rod 13, driving a group of closing plates 11 to close the first through groove 9 to prevent the feed from continuing to fall, thereby solving the problem of too high cost of controlling feeding by sensors.

[0032] A motor 14 is provided in the cylinder 8; a first rotating rod 15 is provided at the output end of the motor 14; the top of the first rotating rod 15 is rotatably connected to the inner top wall of the cylinder 8 and passes through the top of the cylinder 8; a support rod 16 is fixedly connected to the top of the first rotating rod 15; both ends of the bottom of the support rod 16 are fixedly connected to stirring plates 17. When working, the motor 14 drives the support rod 16 to rotate, and drives a pair of stirring plates 17 to rotate, so that they can rotate around a group of first through grooves 9 to avoid too much feed gathering near a group of first through grooves 9, which is easy to cause blockage, thereby preventing blockage.

[0033] A second through groove 18 is provided at the bottom of the stirring plate 17; a second elastic telescopic rod 19 is fixedly connected to the groove wall of the second through groove 18; a trapezoidal block 20 is fixedly connected to the telescopic end of the second elastic telescopic rod 19. When working, the trapezoidal block 20 is fixedly connected to the second through groove 18 provided on the stirring plate 17 through the second elastic telescopic rod 19, and can drive the trapezoidal block 20 to rotate at the same time when the motor 14 drives the stirring plate 17 to rotate. Through the elastic force of the second elastic telescopic rod 19, the trapezoidal block 20 can generate an impact when it is located in the first through groove 9, effectively preventing blockage.

[0034] The second connecting rod 13 is provided with a second sliding groove 21; a pressing block 22 is slidably connected in the second sliding groove 21, and the bottom of the pressing block 22 is fixedly connected to the groove wall of the second sliding groove 21 through a spring; a sliding rod 23 is fixedly connected to the pressing block 22, and the sliding rod 23 is slidably connected in the second sliding groove 21; a group of cross rods 24 are fixedly connected to the sliding rod 23. During operation, by setting a group of cross rods 24 fixedly connected to the sliding rod 23, when the conveying pipe 3 is blocked, the staff can solve the blockage problem by pressing the pressing block 22, thereby driving the sliding rod 23 to vibrate through the spring.

[0035] The bottom plate 1 is provided with a group of fixing holes 25. During operation, the fixing holes 25 can facilitate the staff to fix the whole body and improve the overall stability.

[0036] The trapezoidal block 20 is tilted toward the conveying pipe 3. When working, the trapezoidal block 20 is tilted toward the conveying pipe 3, so that the vibration generated by the trapezoidal block 20 can be mainly directed to the blocked material to avoid blockage.

[0037] The inner bottom wall of the storage hopper 2 is an inclined surface 26. When working, the inner bottom wall of the storage hopper 2 is an inclined surface 26, which can make the feed flow better and facilitate the feed delivery pipe to transport the feed.

[0038] Working principle: The feed reaches the pressing plate 5 under the conveying of the conveying pipe 3, exerting a downward pressure on the pressing plate 5. When the contraction force of the first elastic telescopic rod 6 is insufficient, the pressing plate 5 reaches the bottom of the feeding trough 4. At the same time, the second connecting rod 13 drives the cross plate 12 to move downward, driving a group of closing plates 11 to close the first through slots 9 to prevent the feed from continuing to fall, and then driving the closing member to close a group of first through slots 9. After the farmed sheep eat to a certain position, the elastic force of the first elastic telescopic rod 6 will move the pressing plate 5 up to a certain position, and control the closing member to open and continue feeding. The above scheme solves the problem that the current feeding trough usually requires a gravity sensor to control the feeding, the sensor is expensive, and the sensor is prone to various faults, resulting in the failure of the automatic feeding function and affecting the normal feeding of the feed. The motor 14 is provided to drive the support rod 16 to rotate, and then drive a pair of stirring plates 17 to rotate, so that they can rotate around a group of first through grooves 9, so as to avoid too much feed from gathering near a group of first through grooves 9 and causing blockage, thereby preventing blockage. The trapezoidal block 20 is fixedly connected to the second through groove 18 provided in the stirring plate 17 through the second elastic telescopic rod 19, so that when the motor 14 drives the stirring plate 17 to rotate, the trapezoidal block 20 can be driven to rotate at the same time. The elastic force of the second elastic telescopic rod 19 can make the trapezoidal block 20 generate an impact when it is located in the first through groove 9, thereby improving the anti-blocking effect. The problem of blockage can be solved. A group of cross rods 24 are fixedly connected to the sliding rod 23. When the conveying pipe 3 is blocked, the staff can press the pressing block 22 to make the spring drive the sliding rod 23 to vibrate to solve the blockage problem. The fixing holes 25 can facilitate the staff to fix the whole body and improve the overall stability. The trapezoidal block 20 is tilted toward the conveying pipe 3, so that the vibration generated by the trapezoidal block 20 can be mainly aimed at the blocked material, thereby avoiding blockage. The inner bottom wall of the storage hopper 2 is an inclined surface 26, which can make the feed flow better, so that the feed delivery pipe can be conveniently transported. In summary, the feed trough with feeding function described in the utility model, with its unique mechanical design and innovative anti-blocking function, provides an efficient and stable feed feeding solution for the breeding industry.

[0039] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
