Description

Technical Field

[0001] The utility model relates to the technical field of poultry breeding equipment, in particular to an oblique scraping type excrement cleaning device. Background Art

[0002] With the large-scale development of the poultry breeding industry, most large-scale poultry farms currently use stacked poultry cages for breeding in order to facilitate cleaning management and improve breeding and prevention effects. A large amount of feces will be produced during poultry breeding, which needs to be cleaned up in time. In addition, for stacked breeding cages, in order to ensure that the feces excreted from the upper layer will not fall to the lower layer, a feces collection belt is often set between the two layers of cages. The feces excreted by the poultry falls on the feces collection belt through the cage body. The breeding staff needs to regularly clean the feces on each layer of the feces collection belt, sterilize and disinfect it, so as to improve the breeding environment. However, due to the large number of poultry farms and the large area occupied, the breeding staff have a huge workload, and there are problems such as untimely cleaning and low work efficiency. In order to solve the above problems, two manure cleaning methods are often used in the prior art. First, the existing chicken cage manure removal device mainly uses a motor to drive a cable to pull a separate scraper to scrape the chicken manure on the manure belt to a manure pit at the end of the manure belt for centralized treatment. Each time the manure belt is cleaned, the scraper must move from the end of the manure belt away from the manure pit to the manure pit. This type of one-way chicken manure scraping device can clean the chicken manure to a certain extent, but the effect of scraping away the chicken manure is not thorough. The residual chicken manure affects the sanitary conditions of the chicken cage, resulting in an increased probability of chickens being infected and sick. Second, in the prior art, the chicken cage automatic manure cleaning device directly drives the manure belt to rotate through a motor. The rotation speed of the manure belt is too fast, and the scraper does not clean the chicken manure completely. The manure belt is not stable enough when rotating due to the looseness of the manure belt. When the manure belt is carrying chicken manure, the running distance is too large and the carrying capacity will increase, thereby causing the manure belt to run slower, the motor load increases, and the power consumption increases.

[0032] The following further details the specific implementation mode of the present invention with reference to the drawings:

[0033] As Figure 1As shown in the figure, an inclined scraping manure cleaning device is mainly applied to stacked poultry breeding cages. The stacked poultry breeding cages are arranged in multiple layers of cages. To ensure that the excrement of the upper-layer poultry does not fall to the lower layer, manure belts (not shown in the figure) are fixedly installed below each layer of cages. The two ends of the manure belt are fixed by a manure belt tensioning device, so that the manure belt always remains in a tensioned state. In order to clean the manure on the manure belt, the inclined scraping manure cleaning device of the present utility model can make a reciprocating motion and adjust the direction of the internal manure scraping plate according to the motion direction, which is convenient for thoroughly cleaning the manure on the manure belt. An inclined scraping manure cleaning device mainly includes a general support 1 and multiple layers of manure cleaning devices arranged inside the general support 1. Each layer of manure cleaning device is correspondingly arranged below each layer of breeding cages, and has the same structure, including a driving mechanism 3, a manure scraping mechanism 2 divided into two columns and centrosymmetrically arranged, and a guiding and supporting mechanism 4 corresponding to the manure scraping mechanism 2.

[0034] The general support 1 is integrally in a frame structure, providing a support and fixing foundation for the entire device. It includes a left support assembly 11, a right support assembly 12, and multiple support cross beams 13 fixedly installed between the left support assembly 11 and the right support assembly 12 by bolts. Every two support cross beams 13 arranged at the same height are symmetric to each other and form one layer. A sliding groove 15 is provided along the length direction on the inner side of each support cross beam 13. The left support assembly 11 and the right support assembly 12 are symmetrically arranged, and have the same structure, each including two relatively parallel first columns 101 and multiple transverse fixing beams 102 fixedly installed between the two first columns 101. The transverse fixing beams 102 at the same installation height and the support cross beams 13 together enclose the support frame of the single-layer manure cleaning device. According to the requirements of actual breeding conditions, the overall setting length of the general support 1 is likely to be relatively long, which leads to a large transverse span of the support cross beams 13. In order to ensure the support stability of the support cross beams 13 and prevent the occurrence of shaking phenomena, multiple vertically arranged second columns 14 for reinforcement are uniformly fixedly installed on the outer sides of the above-mentioned multiple layers of support cross beams 13.

[0035] Combined Figure 2 and Figure 3 As shown in the figure, taking the single-layer manure cleaning device as an example, the guiding and supporting mechanism 4 in the manure cleaning device is symmetrically arranged in two columns, corresponding to the two columns of the manure scraping mechanism 2 arranged at intervals. Each column of the guiding and supporting mechanism 4 includes a support guiding rod 41, multiple connecting rods 42 for fixing the support guiding rod 41, and a T-shaped slider 43 adaptively installed on the support guiding rod 41. The support guiding rod 41 is parallel to the inner side of the support cross beam 13, located at the central position of the single-layer support frame, and is fixedly installed on the support cross beam 13 on the same side through multiple connecting rods 42 and is relatively fixed.

[0036] In the manure cleaning device, the single-row manure scraping mechanism 2 is slidably installed above the support guide rod 41 through a T-shaped slider 43, and is erected on the support guide rod 41 and the support cross beam 13 on the same side. Combining Figure 4 As shown, the manure scraping mechanism 2 includes a moving platform 21, a movable manure scraping plate 22 arranged above the moving platform 21, and a manure scraping plate adjusting mechanism. Among them, multiple T-shaped sliders 43 are fixedly installed at the bottom of one side of the moving platform 21 close to the support guide rod 41, and are slidably installed on the support guide rod 41 in an adapted manner; one side edge of the moving platform 21 close to the support cross beam 13 on the same side is bent upward into a vertical wall structure, and multiple sliders are fixedly installed on the outer side of the vertical wall structure, which can be slidably installed in the sliding groove 15 inside the support cross beam 13, ensuring that the moving platform 21 can reciprocate horizontally along the support guide rod 41 and the support cross beam 13. A scraper support frame 25 is fixedly installed on the inner side of the vertical wall of the moving platform 21, and the movable manure scraping plate 22 is rotatably installed at the head of the scraper support frame 25 through a rotating shaft 29, and is spaced from the upper surface of the moving platform 21. The above-mentioned manure belt is placed between the moving platform 21 and the movable manure scraping plate 22, and the bottom of the movable manure scraping plate 22 is closely attached to the surface of the manure belt. Combining Figure 9 As shown, the bottom edges of the movable manure scraping plates 22 are flush, and an integrally formed manure blocking strip is further provided on the upper edge. The manure blocking strip is arranged obliquely upward and points to the manure scraping side of the movable manure scraping plate 22, preventing excrement from falling behind the movable manure scraping plate 22 during the scraping process, resulting in unclean cleaning; two hanging ears 26 are fixedly installed on the back side of the movable manure scraping plate 22, respectively located on both sides of its rotation installation center, and an adjusting rod 27 is hinged on each hanging ear 26. The manure scraping plate adjusting mechanism includes two guide wheels 23 and two adjusting steel wires 24. Among them, the two guide wheels 23 are both fixedly installed on the inner side of the vertical wall through a guide wheel bracket, respectively located on both sides of the tail end of the scraper support frame 25; one end of each of the two adjusting steel wires 24 is fixedly connected to the movable end of the adjusting rod 27 on the corresponding side, and the other end is fixed in the driving mechanism 3 after passing around the guide wheel 23 on the corresponding side. The movable manure scraping plate 22 is driven by the adjusting steel wire 24 to rotate relative to the head of the scraper support frame 25 to complete the direction change. At the same time, scraper blocking structures 28 are fixedly installed at both ends of the inner side of the vertical wall of the moving platform 21. The two scraper blocking structures 28 are bent, and the bending angle can be selected as 120°. They can be attached to the end of the movable manure scraping plate 22 after the direction change to form a blocking limit. At this time, the inner end of the movable manure scraping plate 22 is closely attached to the inner edge of the manure belt, and the outer end of the movable manure scraping plate 22 protrudes from the outer edge of the manure belt, and can guide the excrement on the manure belt into the middle manure dropping channel.

[0037] The driving mechanism 3 provides power for the reciprocating motion of the two rows of manure scraping mechanisms 2 and can drive the manure scraping mechanism 2 to slide along the guiding and supporting mechanism 4. The driving mechanism 3 includes a driving motor 31, a driving side pulley group 32, a driven side pulley group 33 and a driving steel wire rope 34. As shown in combination with Figure 5 and Figure 6 , the driving side pulley group 32 includes a first pulley group bracket 323, four first vertical pulleys 322 and two first horizontal pulleys 324. The cross-section of the first pulley group bracket 323 is in a U-shaped structure and is fixedly buckled by bolts at the inner center position of the corresponding horizontal fixed beam 102 of the left bracket assembly 11. The output end of the driving motor 31 is fixedly connected with a speed reducer, and the speed reducer is fixedly installed on the inner side of the first pulley group bracket 323 by bolts. Its output shaft passes through the first pulley group bracket 323 and extends into its interior. The end of the output shaft is coaxially and fixedly installed with a driving pulley 321 through a key; the four first vertical pulleys 322 are grouped in pairs and are respectively rotatably installed between the first pulley group bracket 323 and the horizontal fixed beam 102, on both sides of the driving pulley 321, and are arranged in a staggered up and down manner, and the wheel diameter of the first vertical pulley 322 is smaller than the wheel diameter of the driving pulley 321; the two first horizontal pulleys 324 are respectively installed at the two ends of the horizontal fixed beam 102 through pulley brackets and are located at the corners of the same layer of the frame structure for steering. Similarly, as shown in combination with Figure 7 , the driven side pulley group includes a second pulley group bracket 333, two second vertical pulleys 332, an adjustable driven pulley 331 and two second horizontal pulleys 334. The cross-section of the second pulley group bracket 333 is also in a U-shaped structure and is fixedly buckled by bolts at the inner center position of the same-layer horizontal fixed beam 102 in the right bracket assembly 12; the adjustable driven pulley 331 is arranged at the inner center of the second pulley group bracket 333. As shown in combination with Figure 8As shown, the adjustable driven pulley 331 includes an adjustable sliding frame 337, a driven pulley 336, fixed slide rails 335, and an adjustment screw 339. Two symmetric fixed slide rails 335 are respectively vertically and fixedly installed on the inner side of the second pulley set bracket 333 and the horizontal fixed beam 102 in the right bracket assembly 12, arranged oppositely, and an adjustment plate 338 is fixedly installed horizontally at their lower ends. The adjustment plate 338 is provided with an adjustment through hole. The adjustable sliding frame 337 is slidably installed on the two fixed slide rails 335 and can slide up and down along them. The driven pulley 336 is rotatably installed inside the adjustable sliding frame 337 through a rotating shaft. The upper end of the adjustment screw 339 is rotatably connected to the bottom of the adjustable sliding frame 337, and its lower end passes downward through the adjustment through hole and is relatively adjusted and fixed by a fastening nut. By extending and retracting the adjustment screw 339, the up and down movement of the adjustable sliding frame 337 and the driven pulley 336 can be driven and the position can be fixed. The two second vertical pulleys 332 are respectively rotatably installed between the second pulley set bracket 333 and the corresponding horizontal fixed beam 102 through rotating shafts, on both sides of the adjustable driven pulley 331. The two second horizontal pulleys 334 are respectively installed at the two ends of the horizontal fixed beam 102 through pulley brackets, at the right two corners of the same layer of frame structure, for steering. All the first horizontal pulleys 324, second horizontal pulleys 334, and the guide wheels 23 in the manure scraping mechanism 2 on the same layer are on the same horizontal plane.

[0038] The driving steel wire rope 34 is selected as a long steel wire rope, which can be looped around all the pulleys in the same layer of the frame and connected end to end. Refer to Figure 2As shown in the figure, the driving steel wire rope 34 starts from the driving pulley 321, winds around the circumferential groove of the driving pulley for two weeks, then passes forward through two first vertical pulleys 322 and extends out of the front side wall of the first pulley group bracket 323; then changes direction after winding around the front first horizontal pulley 324, passes through the vertical wall of the moving platform 21 in the manure scraping mechanism 2 in the front row and extends to the second horizontal pulley 334 on the front side; then changes direction and passes through the front side wall of the second pulley group bracket 333, winds around the second vertical pulley 332 and the adjustable driven pulley 331. By adjusting the height of the adjustable driven pulley 336, the tension of the entire driving steel wire rope 34 is controlled to always be in a tensioned state, thereby increasing the rotational friction force between the driving steel wire rope 34 and each pulley; then extends out of the rear side wall of the second pulley group bracket 333 and winds around the rear second horizontal pulley 334 to change the direction; then passes through the vertical wall of the moving platform 21 in the manure scraping mechanism 2 in the rear row and extends to the first horizontal pulley 324 on the rear side, changes direction and passes through the rear side wall of the first pulley group bracket 323, winds around the two first vertical pulleys 322 on the rear side and then connects end to end, so as to provide power for the reciprocating movement of the two rows of manure scraping mechanisms 2 through the friction force between the driving steel wire rope 34 and the driving pulley 321. At this time, the other ends of the two adjusting steel wire ropes 24 in the manure scraping mechanism 2 are respectively fixedly connected to the driving steel wire rope 34 passing through the moving platform 21 through fixed buckles, and the manure scraping plate 22 is pulled through the guide pulley 23 by the pulling of the driving steel wire rope 34 to change the manure scraping direction of the manure scraping plate 22. Combining with Figure 6 As shown in the figure, in order to adapt to the number of winding turns of the driving steel wire rope 34 on the driving pulley 321, the two groups of first vertical pulleys 322 on both sides of the driving pulley 321 are in two different and parallel vertical planes.

[0039] A further optimized technical solution, combining Figure 2 As shown in the figure, a travel switch 5 is fixedly installed on each layer of support cross beam 13 of the total support 1. There are two groups of travel switches 5 on each support cross beam 13, respectively located at the end sides of the corresponding manure scraping mechanism 2 in the movement direction. By detecting the contact of the moving platform 21 in the manure scraping mechanism 2, the reciprocating movement position and distance of the manure scraping mechanism 2 are limited, thereby controlling the rotation of the driving motor 31, changing the scraping direction of the manure scraping plate 22, and then reciprocatingly removing manure from the manure belt.

[0040] A further optimized technical solution is that the bottoms of the above-mentioned first upright column 101 and the second upright column 14 can be detachably installed with support feet capable of adjusting the height to adapt to different breeding installation environments, reduce installation errors, and improve the stability of the entire device after installation.

[0041] As another optimized technical solution of the present utility model, in the above-mentioned manure cleaning device, the support guide rod 41 in the guide support mechanism 4 may not be installed separately, and the top cross beam of the targeted poultry breeding cage body can also be used for guiding and supporting functions without being set up separately, which can reduce the corresponding processing and manufacturing costs.

[0042] Certainly, the above description is not a limitation to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model should also fall within the protection scope of the present utility model.
