Description

Technical Field

[0001] The invention relates to the field of laying hen breeding equipment, in particular to a cleaning device for a laying hen breeding feed trough. Background Art

[0002] In the modern laying hen farming industry, the cleaning and maintenance of feed troughs is extremely important. A healthy farming environment is the basis for ensuring the good growth of laying hens and improving the quality and quantity of egg production. The feed trough is a key utensil for laying hens to eat, and its cleanliness directly affects the health of laying hens and the farming benefits.

[0003] At present, the feed trough cleaning methods adopted by most farms are still relatively traditional and extensive. Manual cleaning is one of the common methods. Farmers need to use simple tools such as brushes and water pipes to scrub and rinse the feed troughs one by one. This method not only consumes a lot of manpower and time, but also has extremely low cleaning efficiency. In large-scale breeding scenarios, manual cleaning often cannot meet the production rhythm requirements, resulting in untimely cleaning of the feed trough, which in turn affects the health of laying hens. At the same time, manual cleaning is difficult to ensure the consistency of cleaning quality. It is difficult to completely remove the residual feed that is firmly adhered to the feed trough. Long-term accumulation is prone to breed harmful microorganisms such as bacteria and mold, contaminating the feed and causing laying hen diseases.

[0004] Although some farms have introduced some simple mechanized cleaning equipment, these devices generally have design defects. For example, some equipment can only perform simple surface cleaning and cannot deeply clean the corners and gaps of the feed trough; some equipment cannot effectively remove stubborn feed residues during the cleaning process, and the cleaning effect is poor. Moreover, most of these equipment lack an effective collection and treatment mechanism for cleaning waste liquid and residual feed, which can easily cause secondary pollution of the breeding environment and increase the difficulty of subsequent cleaning and maintenance.

[0005] In addition, existing cleaning equipment often has poor versatility and is difficult to adapt to feed troughs of different shapes and specifications. In actual farming, the design of feed troughs varies depending on factors such as farming scale and farming methods, which requires cleaning equipment to have better adaptability and flexibility. However, the cleaning equipment currently on the market can hardly meet this demand, limiting its widespread application in the farming industry. Summary of the invention

In the middle of the bottom end of the inverted trapezoidal shell 1, a first cleaning bin 2 is precisely opened, and the first cleaning bin 2 provides a key working space for subsequent cleaning operations. In the middle of the top end of the inverted trapezoidal shell 1, a DC motor 3 is fixedly installed through a stable mounting seat. The driving end of the DC motor 3 extends to the interior of the inverted trapezoidal shell 1 through a sealed bearing, and is fixedly installed with the main shaft 4 by a key connection to ensure stable power transmission. The end of the main shaft 4 also extends to the interior of the first cleaning bin 2 through a tight connection structure, and is fixedly installed with a first cross brush plate 5. The first cross brush plate 5 is made of a wear-resistant material with a certain elasticity, and its bristle length and hardness are carefully designed to effectively brush the inside of the feed trough.

[0028] On both sides of the bottom end of the inverted trapezoidal shell 1, second cleaning chambers 6 are symmetrically opened. The second cleaning chamber 6 and the first cleaning chamber 2 together constitute a comprehensive cleaning system. In the middle of the inner end of the second cleaning chamber 6, a rotating shaft 7 is movably installed through a bearing, so that the rotating shaft 7 can rotate flexibly. The outer ends of the rotating shaft 7 extend to the interior of the second cleaning chamber 6 through a sealing structure, and a second cross brush plate 8 is fixedly installed. The structure and material of the second cross brush plate 8 are similar to those of the first cross brush plate 5, and can cooperate with the first cross brush plate 5 to carry out a more comprehensive cleaning of the feed trough.

[0029] The front side of the inverted trapezoidal housing 1 is movably provided with an inverted trapezoidal bracket 11 through a guide rod 13. The guide rod 13 plays a good guiding role to ensure the stability of the movement of the inverted trapezoidal bracket 11. A plurality of bristle brushes 12 are evenly fixedly installed at the bottom end of the inverted trapezoidal bracket 11. The bristles of the bristle brushes 12 are specially treated to have strong wear resistance and rigidity, and can effectively peel off the residual feed firmly adhered to the inner surface of the feed trough. The rear side of the inverted trapezoidal housing 1 is fixedly provided with a collecting chamber 23 through a firm connection method such as welding. The collecting chamber 23 is used for To collect the waste liquid and residual feed generated during the cleaning process, a fixed seat 24 is fixedly installed on one side of the interior of the collecting chamber 23. The fixed seat 24 is made of high-strength material, and three suction channels 25 are precisely opened inside it. The outer ends of the suction channels 25 are connected to the outside through sealed pipes to ensure the sealing of the suction process. On the top side of the collecting chamber 23, a negative pressure fan 26 is fixedly installed through a shock-absorbing mounting seat. The negative pressure fan 26 has the characteristics of high power and high efficiency, and can quickly draw the collection chamber 23 to a vacuum state.

[0030] In this embodiment, a bracket 27 is also included. The bracket 27 adopts a solid metal frame structure with sufficient strength and stability. A vertical linear motion module 28 is fixedly installed on one side of the top end of the bracket 27 by bolts. The driving end of the vertical linear motion module 28 is fixedly installed with a movable block 29 by threaded connection, which can realize the precise up and down movement of the movable block 29. A bent connecting rod 30 is fixedly installed on one side of the movable block 29 by welding, and the end of the bent connecting rod 30 is also firmly fixedly installed on the top side of the inverted trapezoidal shell 1 by welding, thereby realizing the height adjustment of the inverted trapezoidal shell 1. Universal wheels 34 are fixedly installed at the four corners of the bottom end of the bracket 27 through mounting seats.

[0031] Furthermore, a multi-way pipe 21 is fixedly installed on the front side of the top end of the inverted trapezoidal shell 1 by welding or threaded connection. The multi-way pipe 21 plays a key role in diverting the cleaning liquid. Three branch pipes 22 are fixedly installed on the bottom end of the multi-way pipe 21. The ends of the branch pipes 22 extend to the interior of the first cleaning chamber 2 and the two second cleaning chambers 6 by sealed connections, respectively, to ensure that the cleaning liquid can be accurately delivered to each cleaning chamber.

[0032] Furthermore, a cleaning liquid storage tank 31 is fixedly installed on the other side of the top of the bracket 27 through a fixed bracket. The cleaning liquid storage tank 31 is made of corrosion-resistant material and can store sufficient cleaning liquid. A delivery pump 32 is fixedly installed on the top of the cleaning liquid storage tank 31 through a shock-absorbing mounting seat. The input end of the delivery pump 32 extends to the interior of the cleaning liquid storage tank 31 through a sealed pipe, and the output end of the delivery pump 32 is fixedly installed with a liquid delivery pipe 33 through a sealed connection, and the end of the liquid delivery pipe 33 extends to the interior of the multi-way pipe 21 through a sealed connection, thereby realizing stable delivery of the cleaning liquid.

[0033] Furthermore, a driving gear 9 is fixedly mounted on the upper outer diameter of the main shaft 4 through a key connection. The tooth shape of the driving gear 9 is precisely designed to ensure the smoothness of the transmission. A driven gear 10 is fixedly mounted on the inner end of the rotating shaft 7 through a key connection, and the inner ends of the driven gear 10 are respectively meshed with the two sides of the driving gear 9. Through this gear transmission structure, the coordinated work of multiple components is achieved.

[0034] Furthermore, both sides of the top of the inverted trapezoidal bracket 11 are movably arranged on the upper surface of the inverted trapezoidal shell 1 through a guide rod 13, and a sliding fit is adopted between the guide rod 13, the inverted trapezoidal bracket 11 and the inverted trapezoidal shell 1 to ensure smooth movement. Both sides of the middle part of the inverted trapezoidal bracket 11 are connected to the front side of the inverted trapezoidal shell 1 through a reset spring 14. The reset spring 14 has a suitable elastic coefficient and can provide a reset force during the movement of the inverted trapezoidal bracket 11.

[0035] Furthermore, a driving bevel gear 15 is fixedly installed on the lower outer diameter of the main shaft 4 through a key connection. The tooth shape and material of the driving bevel gear 15 are carefully designed to meet the transmission requirements of high loads. A transmission shaft 16 is movably installed on the front lower side of the inverted trapezoidal housing 1 through a bearing. The inner end of the driving bevel gear 15 extends to the interior of the inverted trapezoidal housing 1 through a sealing structure, and a driven bevel gear 17 is fixedly installed through a key connection. The driven bevel gear 17 and the inner ends of the driving bevel gear 15 are meshed and connected with each other to achieve the steering transmission of power. The outer end of the transmission shaft 16 extends to the outside of the inverted trapezoidal housing 1 through a sealing structure, and a first chuck 18 is fixedly installed through a key connection. A second chuck 19 is fixedly installed on the inner middle part of the inverted trapezoidal bracket 11 by welding. A plurality of hemispherical protrusions 20 are fixedly installed on the inner ends of the first chuck 18 and the second chuck 19, and the installation positions of these hemispherical protrusions 20 are staggered to form a unique tooth structure.

[0036] Working principle: First, the operator pushes the bracket 27, and uses the universal wheels 34 installed at the four corners of the bottom of the bracket 27 to easily move the inverted trapezoidal shell 1 to the inside of the laying hen feed trough. Since the shape of the inverted trapezoidal shell 1 is highly consistent with the laying hen feed trough, it can fit tightly against the inner wall of the feed trough, laying the foundation for subsequent efficient cleaning. Then, the DC motor 3 is started, and the DC motor 3 starts to work. The driving end drives the main shaft 4 connected to it by a key to rotate, and the rotation of the main shaft 4 drives the active bevel gear 15 fixedly installed on the outer diameter of its lower side to rotate together. The rotating active bevel gear 15 transmits power to the driven bevel gear 17 through meshing transmission with the driven bevel gear 17, and the driven bevel gear 17 drives the transmission shaft 16 connected to it by a key to rotate, thereby driving The first chuck 18 fixedly mounted on the outer end of the transmission shaft 16 rotates, and the unique tooth structure formed by the mutually offset hemispherical protrusions 20 between the first chuck 18 and the second chuck 19, combined with the effect of the return spring 14 connected on both sides of the middle of the inverted trapezoidal bracket 11, enables the inverted trapezoidal bracket 11 to reciprocate rapidly under the guidance of the guide rod 13. In this way, the bristle brush 12 fixedly mounted on the bottom of the inverted trapezoidal bracket 11 also reciprocates rapidly, and quickly scrubs the inside of the laying hen feed trough, which can effectively peel off the residual feed firmly adhered to the inner surface of the feed trough, significantly improving the cleaning quality. Subsequently, the delivery pump 32 is started, and the delivery pump 32 starts to work, and the cleaning liquid in the cleaning liquid storage tank 31 is sucked in through the sealed pipe at its input end. Then it is pumped out through the liquid delivery pipe 33 at the output end, and the liquid delivery pipe 33 delivers the cleaning liquid into the multi-way pipe 21, and the multi-way pipe 21 then delivers the cleaning liquid into the first cleaning chamber 2 and the two second cleaning chambers 6 through three branch pipes 22 respectively. In addition, when the main shaft 4 rotates, it will also drive the first cross brush plate 5 fixedly installed in the first cleaning chamber 2 at its end to rotate at high speed. At the same time, when the main shaft 4 rotates, it will also drive the driving gear 9 fixedly installed on the outer diameter of its upper side to rotate. The rotating driving gear 9 meshes with the driven gears 10 on both sides to drive the driven gear 10 and the rotating shaft 7 keyed thereto to rotate, thereby driving the second cross brush plate 8 in the second cleaning chamber 6 to rotate at high speed. The high-speed rotating first cross brush plate 5 and the second cross brush plate 8 will be pumped into the first cleaning chamber 2 and the cleaning liquid in the second cleaning chamber 6 are scattered into fine water droplets, which are mixed with air to form a high-speed cleaning liquid gas flow, which quickly and deeply cleans the inner surface of the feed trough. Finally, the negative pressure fan 26 is started. The high-power negative pressure fan 26 quickly pumps the collection chamber 23 to a vacuum state in an instant. At this time, the strong atmospheric pressure sucks the waste liquid and residual feed generated by cleaning into the collection chamber 23 through the suction channel 25 opened inside the fixed seat 24. The waste liquid and residual feed entering the collection chamber 23 are affected by gravity and naturally fall to the bottom of the collection chamber 23 to complete the collection work. The operator pushes the bracket 27 to drive the inverted trapezoidal shell 1 to move along the direction of the feed trough, so as to complete the cleaning work of the entire feed trough. At the same time,The operator can also start the vertical linear motion module 28 according to the feed troughs at different heights, and drive the movable block 29 to move up and down through its driving end. The movable block 29 then uses the bent connecting rod 30 to make the inverted trapezoidal housing 1 enter the feed troughs at different heights for cleaning. The whole operation process is simple and convenient, with high cleaning effect and quality.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
