Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning breeding grounds, in particular to a scraper mechanism for cleaning excrement in a dairy farm. Background Art
[0002] With the development of science and technology, China has completed the transformation from traditional farming to mechanized planting. The oxen have disappeared in the long river of history, replaced by beef cattle, dairy cows, and dual-purpose cattle. The cattle-raising method has changed from free-range to factory-based, intensive, refined, and intelligent, and the scale of breeding has further expanded. In order to avoid infectious diseases such as foot-and-mouth disease from raging in the cattle herd, causing economic losses to farmers, and also to obtain high-quality meat, milk and other products, a clean and healthy cattle house environment is essential. Therefore, it is necessary to clean the excrement in the cattle house in time. A set of safe and reliable scrapers can provide reliable support for the normal operation of the cattle farm.
[0003] At present, most of the cowsheds are built with traditional methods such as concrete pouring and plastering for both the ground and underground parts, and their construction precision is relatively low. At the same time, because the cowshed area is large and the scraper runs a long distance, the excrement at the corners cannot be completely cleaned. Over time, raised obstacles that hinder the scraper from moving forward are formed on the edge of the cowshed scraping path. In the cold winter in the north, the temperature is below zero degrees Celsius for a long time, which makes these raised obstacles extremely hard. When the scraper is driven forward by the motor, it encounters these raised obstacles and can only collide with each other, causing the scraper's movable arm to deform, and in severe cases, break, resulting in the excrement cannot be cleaned in time, causing damage to the cattle farm.
[0004] Therefore, the present application provides a scraper mechanism for cleaning excrement in a dairy farm, which can fundamentally solve the occurrence of such problems through its own retractable scraper assembly, thereby providing a guarantee for the stable operation of the dairy farm. Utility Model Content
[0005] The purpose of the utility model is to overcome the defects and shortcomings of the prior art and to provide a scraper mechanism for cleaning excrement in a dairy farm, which can retract itself when encountering an obstacle and return to its original shape when crossing the obstacle, thereby solving various problems existing in the prior art.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A scraper mechanism for cleaning excrement in a dairy farm comprises a scraper arm fixing frame, symmetrically arranged left and right scraper fixed arms are respectively installed on both sides of the scraper arm fixing frame, scrapers are respectively installed on the bottom ends of the front end surfaces of the left and right scraper fixed arms, and left and right scraper movable arms are respectively installed on the outer ends of the left and right scraper fixed arms. The left and right scraper movable arms are segmented structures, the middle of which is a high-elastic rubber connecting block, one side of the high-elastic rubber connecting block is fixedly connected to a first scraper movable arm, the end of the first scraper movable arm is provided with a connecting sleeve connected to the scraper fixed arm, and the other side is fixedly connected to a second scraper movable arm, and the end of the second scraper movable arm is provided with a roller for vertical rotation for touching an obstacle.
[0008] The upper end surface of the scraper arm fixing frame is provided with mounting and fixing holes, and the mounting and fixing holes can connect and fix the scraper arm fixing frame with the traveling connecting piece.
[0009] A guide groove is provided at the bottom end of the scraper arm fixing frame, and the guide groove cooperates with the guide of the scraper travel track laid on the ground.
[0010] A reinforcing connecting rib is arranged at the middle part of the front end surface of the left and right scraper fixing arms.
[0011] The outer end surfaces of the left and right scraper fixed arms are respectively provided with connecting seats, and the connecting seats are connected and fixed to the left and right scraper movable arms through connecting shafts, and the left and right scraper movable arms are inclined at a certain angle.
[0012] The left and right scraper fixed arms on both sides of the connecting shaft are provided with limit plates for limiting the movable angles of the left and right scraper movable arms.
[0013] The high-elastic rubber connecting block is connected and fixed to the first scraper movable arm and the second scraper movable arm through connecting bolts.
[0014] The roller is made of rubber.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The utility model has a reasonable structural design. Through the structure of the movable and elastic telescopic left and right scraper movable arm components, the scraper can shrink by itself when encountering an obstacle, and can restore the original scraper when crossing the obstacle, avoiding mutual hard collision, resulting in deformation of the scraper movable arm, and in severe cases, fracture, causing losses, thereby providing guarantee for the stable operation of the cattle farm;
[0017] Specifically, when the scraper is moving forward and encounters obstacles raised on both sides, the roller rolling structure can reduce the hard collision force and the damage caused by the hard collision, protect the scraper structure, and combine the movement of the left and right scraper movable arms to avoid obstacles within a certain range.
[0018] On the other hand, the rollers will also be compressed when they touch, and the force will be transmitted to the high-elastic rubber connecting block through the scraper's movable arm, causing the high-elastic rubber connecting block to be compressed, reducing the actual length of the left and right scraper's movable arms. When passing through the raised obstacle, the high-elastic rubber connecting block returns to its original state, and the scraper continues to move forward, ultimately achieving its purpose.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See attached Figure 1-3 ;
[0026] A scraper mechanism for cleaning excrement in a dairy farm comprises a scraper arm fixing frame 3, symmetrically arranged left and right scraper fixing arms 2 and 6 are respectively installed on both sides of the scraper arm fixing frame 3, scrapers 15 are respectively installed on the front end bottom ends of the left and right scraper fixing arms 2 and 6, and left and right scraper movable small arms 1 and 7 are respectively installed on the outer ends of the left and right scraper fixing arms 2 and 6. The left and right scraper movable small arms 1 and 7 are segmented structures, wherein the middle part is a high-elastic rubber connecting block 9, which is connected to the first scraper movable small arm 8 and the second scraper movable small arm 8 through a connecting bolt 12. The movable arm 10 is connected and fixed (a connecting through hole can be set on the high-elastic rubber connecting block 9, and its connection is achieved by connecting bolts, flat washers and locking nuts to achieve stable connection and fixation with the first scraper movable arm 8 and the second scraper movable arm 10); the first scraper movable arm 8 is fixedly connected to one side of the high-elastic rubber connecting block 9, and a connecting sleeve connected to the scraper fixed arm is set at the end of the first scraper movable arm 8, and the second scraper movable arm 10 is fixedly connected to the other side, and a roller 11 for vertical rotation when touching an obstacle is installed at the end of the second scraper movable arm 10, and the roller 11 is made of rubber.
[0027] Furthermore, the upper end surface of the scraper arm fixing frame 3 is provided with installation and fixing holes, and the installation and fixing holes can connect and fix the scraper arm fixing frame 3 with the travel connecting piece. The scraper arm fixing frame is located in the middle of the entire scraper mechanism, so it is connected with the travel connecting piece to ensure the balance and stability of the operation. The commonly used automatic driving method for travel is the circular conveying method of the chain; for example, a circular chain is laid on the ground, and the reciprocating drive is realized through the operation of the circular chain. The bottom end of the scraper arm fixing frame 3 is provided with a guide groove, and the guide groove is guided and matched with the scraper travel track 5 laid on the ground. Through the structure of the scraper travel track 5, on the one hand, the guidance of the scraper arm fixing frame 3 is realized to further ensure the stability of the process. On the other hand, the scraper travel track 5 can support the chain to ensure the stability of the chain during the circulation process. At the same time, the two ends of the chain can be guided and installed on the fixed seats at both ends of the scraper travel track, thereby ensuring the cleaning operation of the scraper.
[0028] Further, the front end surface middle part of the left and right scraper fixed big arms 2, 6 is provided with a reinforcing connecting rib 16. The scraper big arms are strengthened by reinforcing the connecting rib 16, thereby improving the practical life of the scraper.
[0029] Furthermore, the outer end surfaces of the left and right scraper fixed arms 2 and 6 are respectively provided with connecting seats 17, which are connected and fixed to the left and right scraper movable arms 1 and 7 through connecting shafts 18, and the left and right scraper movable arms 1 and 7 are tilted at a certain angle. By tilting the left and right scraper movable arms 1 and 7, when the rollers touch obstacles, the left and right scraper movable arms 1 and 7 can be rotated to avoid them. In addition, torsion springs are installed on the connecting sleeves of the left and right scraper movable arms 1 and 7 and the connecting shafts 18 of the connecting seats 17, so that they can be reset after avoiding obstacles within a certain range of movement. The left and right scraper fixed arms 2 and 6 on both sides of the connecting shaft 18 are provided with limit plates 19 for limiting the moving angles of the left and right scraper movable arms 1 and 7, and the range of their movement is limited by the limit plates.
[0030] Its working principle is: the motor drives the chain or other travel mechanism to drive the scraper arm fixing frame 3 to move, thereby driving the left and right scraper movable arms 1, 7; the left and right scraper fixed arms 2, 6 move on the ground of the cowshed, and the left and right scraper movable arms 1, 7 are connected with the left and right scraper fixed arms 2, 6 through pins. When the scraper is moving forward, when it encounters obstacles raised on both sides, the roller touches the left and right scraper movable arms 1, 7 and the left and right scraper fixed arms 2, 6 to move within the range of movement. If it cannot avoid it, the force is transmitted through the second scraper movable arm 10 through the stressed roller 11. The elastic rubber connecting block 9 is passed to the high-elastic rubber connecting block 9, so that the high-elastic rubber connecting block 9 is compressed to reduce the actual length of the left and right scraper movable arms 17. When passing through the raised obstacle, the high-elastic rubber connecting block 9 returns to its original state, and the scraper continues to move forward, and finally achieves the purpose; its structural design is reasonable, and the rolling, rotating and elastic telescopic combination is adopted, so that the structure of the left and right scraper movable arm assemblies can shrink and adjust the range when encountering obstacles, avoid obstacles, and restore the original scraper when crossing the obstacle, thereby avoiding mutual hard collision, causing deformation of the scraper movable arm, and severe fracture, providing guarantee for the stable operation of the cattle farm.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0032] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
