Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a scraper mechanism for a manure cleaning machine. Background Art

[0002] In the automated chicken farming industry, a manure cleaner is provided under the chicken cage. The manure cleaner includes a conveyor belt, and a plurality of conveyor rollers are provided inside the conveyor belt, wherein the active conveyor roller is located at one end of the conveyor belt, and a scraper is provided at this end to scrape the chicken manure on the conveyor belt. The structure of the scraper in the prior art is shown in the patent application number 202111497605.2 and the name of "A Manure Scraper Mechanism". One side of the manure scraper is movably connected with a scraper rubber strip (a groove is provided on one side of the scraper rubber strip, and one side of the scraper is inserted into the groove). After long-term use, the scraper rubber strip will be severely worn and needs to be replaced. At this time, the scraper rubber strip is still pressed on the conveyor belt and is difficult to replace. The present application provides a scraper mechanism for a manure cleaner that is easy to replace the rubber strip. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a scraper mechanism for a manure cleaning machine in view of the above-mentioned technical deficiencies.

[0004] The cam is an angular movement movement mechanism which moves the rollers relative to the rollers to move relative to each other, the movement of the rollers moving along the rollers being pivotally connected to the rollers, the movement of the rollers moving along the rollers being brought closer to the rollers and the movement of the rollers bringing the rollers within arm's reach.

[0005] As a preferred technical solution of the utility model, a pull rod is provided on the frame, the pull rod is located above the tensioning arm, and the spring is in a tension state.

[0006] As a preferred technical solution of the utility model, the hook includes a vertical rod and a hook body, and the hook body is inclined upward in a direction from approaching to moving away from the vertical rod.

[0007] Compared with the prior art, the utility model has the following advantages: a spring is arranged between the middle part of the tensioning arm and the frame, a handle is slidably connected to the end of the tensioning arm away from the scraper, a hook is rotatably connected to the handle, after the end of the tensioning arm away from the scraper is pulled downward to a certain extent, the hook can be hooked on the positioning rod on the positioning plate, at this time, the rubber strip leaves the conveyor belt and the scraper is fixed, which is convenient for replacing the rubber strip, and when the rubber strip is replaced, hold the handle to slightly press down the outer end of the tensioning arm, and then pull the handle in the direction away from the positioning plate to make the hook out of the length range of the positioning rod, and then control the outer end of the tensioning arm to rise so that the rubber strip contacts the conveyor belt, making the work of replacing the rubber strip simple.

[0011] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0012] Specific implementation method: Combination Figure 1-2As shown, a scraper mechanism for a manure cleaning machine includes a frame 1, one end of the frame 1 is rotatably connected to an active conveying roller 3, a conveyor belt 2 is arranged outside the active conveying roller 3, and a scraper 4 is also included, a rubber strip 41 is movably clamped on the upper side of the scraper 4, a groove is arranged on one side of the rubber strip 41, and the groove can be sleeved on the outer side of the upper side of the scraper 4, and a rotating shaft 14 and a tensioning arm 42 are arranged at both ends of the scraper 4 away from the rubber strip 41, the rotating shaft 14 is rotatably connected to the frame 1, a spring is arranged between the middle part of the tensioning arm 42 and the frame 1 so as to press the rubber strip 41 against the conveyor belt 2 on the front upper side of the outer side of the active conveying roller 3, and a handle is slidably connected to the outer end of the tensioning arm 42 43, so that the handle 43 can slide in the direction parallel to the axis of the rotating shaft 14, one end of the handle 43 is rotatably connected to a hook 44, and a positioning plate 12 is also provided on the frame 1, and a positioning rod 13 is provided on the positioning plate 12. When the tensioning arm 42 is rotated to make the rubber strip 41 leave the conveyor belt 2 by a set distance (the distance is within a certain range, which is convenient for workers to replace the rubber strip 41, and is the optimal distance when the scraper 4 is in a vertical state), the hook 44 can be hung on the positioning rod 13, and there is a gap between the positioning rod 13 and the tensioning arm 42 in the extension direction of the positioning rod 13, so that when the handle 43 is moved a certain distance, the hook 44 can be out of the range of the positioning rod 13.

[0013] Specifically, a pull rod 11 is provided on the frame 1, and the pull rod 11 is located above the tensioning arm 42, and the spring is in a tension state.

[0014] Furthermore, the hook 44 includes a vertical rod and a hook body, and the hook body is inclined upward in a direction from approaching to moving away from the vertical rod. Figure 1 As shown, when the tensioning arm 42 is pulled downward to a certain extent, the lower side of the hook body contacts the upper side of the positioning rod 13, and then the hook 44 will tilt, and its lower end will move to the left, so that the hook body passes over the positioning rod 13, and then under the action of gravity, the hook body moves to the right to the bottom of the positioning rod 13. At this time, release your hand, and the hook body will hook the lower part of the positioning rod 13. At this time, the tensioning arm 42 can remain stationary, and the rubber strip 41 is away from the conveyor belt 2 at a set distance.

[0015] When replacing the rubber strip 41, Figure 1As shown, first move the handle 43 so that the position of the hook 44 is within the length range of the positioning rod 13, then hold the handle 43 to pull the left end of the tensioning arm 42 downward so that the hook 44 hooks the positioning rod 13, then the old rubber strip 41 can be removed and replaced with a new rubber strip 41, then, hold the handle 43 to slightly press down the left end of the tensioning arm 42 so that the hook body of the hook 44 is separated from the positioning rod 13, then pull the handle 43 away from the positioning plate 12 so that the hook 44 is separated from the length range of the positioning rod 13, then continue to hold the handle 43 tightly to control the left end of the tensioning arm 42 to rise until the rubber strip 41 contacts the conveyor belt 2, then the handle 43 can be released and the replacement is completed.

[0016] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the utility model, and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
