Description

Technical Field

[0001] The utility model relates to a dung scraping device, in particular to an automatic dung scraping device for a sheep shed. Background Art

[0002] During the large-scale indoor breeding of meat sheep, effective cleaning of manure can reduce the concentration of harmful gases such as ammonia and hydrogen sulfide in the sheep house, reduce various diseases caused by the breeding of pathogens, and maintain a good air environment required for the survival of sheep.

[0003] Standardized sheep houses mainly use sheep beds with slatted floor structures, which have the advantage of separating sheep from feces and urine. However, manually cleaning feces under the slatted floor is difficult, time-consuming and labor-intensive, and the use of automatic feces scrapers can solve this problem well.

[0004] After searching, Chinese patent documents CN219961615U and CN215935866U disclose an automatic manure scraper. The power device of the manure scraper provides traction to the manure scraper plate to scrape the manure out of the manure collection channel. The steel wire rope is wound on the output end of the power device. The steel wire rope is reversed through the fixed pulley in turn to form a ring structure, which can effectively clean the manure out of the sheep house and improve the efficiency of manure cleaning.

[0005] However, the motor and manure outlet of the above-mentioned scraper power equipment are located at both ends of the sheep house, or there are manure outlets at both ends of the sheep house, and there is no automatic stop device for the power equipment. Workers need to go back and forth between the two ends to complete the start and stop operation of the motor and the removal of sheep manure; in addition, the traction wire rope in the device will be eroded by sheep manure and urine for a long time, dragged and rubbed on the ground for a long time, rusted due to lack of lubricating oil maintenance, and extreme pulling caused by untimely stopping of the motor, all of which will cause the wire rope to break frequently, which not only affects the cleaning of sheep manure but also increases the cost of replacing the wire rope. Therefore, the scraper device still needs to be further optimized in design to reduce the work intensity of workers, extend the service life of the scraper, and reduce the cost of equipment maintenance. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide an automatic manure scraping device for a sheep shed, optimize the existing manure scraping device, reduce the labor intensity of operators, and increase the service life of the equipment.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] An automatic manure scraping device for a sheep shed comprises a manure collecting channel, a manure collecting tank is arranged at the outlet side of the manure collecting channel, a manure scraping plate assembly is placed in the manure collecting channel and connected to a traction rope, and the traction rope is driven by a traction device;

[0009] The manure scraper assembly includes a manure scraper, a connecting bracket is rotatably mounted on the upper end of the manure scraper, and the connecting bracket is connected to the traction rope at the front and rear ends; a supporting leg is rotatably mounted on the back of the manure scraper, and a walking wheel is mounted on the bottom end of the supporting leg, and the walking wheel is in contact with the ground of the manure collecting channel;

[0010] The traction equipment includes multiple groups of first fixed pulleys installed on the outside of the manure collecting channel and the manure collecting tank. The traction rope passes around the multiple groups of first fixed pulleys and two groups of groove wheels on one side of the manure collecting tank to form a circular loop; one group of groove wheels is driven by a driving device.

[0011] There are two groups of manure collecting channels, four groups of corresponding first fixed pulleys are arranged in groups of two in front and back, and two groups of manure scraping plate assemblies are arranged in the corresponding manure collecting channels.

[0012] Support arms are installed at the positions on the scraper board that contact the side walls of the scraper channel. The support arms include a telescopic rod, one end of which is fixed to the scraper board, a spring is sleeved on the middle section of the telescopic rod, and a bearing universal wheel is installed on the other end of the telescopic rod.

[0013] Tracks are fixed above the manure collecting channel and the manure collecting pool, and covers inclined outward and downward are fixed on the left and right sides of the tracks. The traction rope is located below the cover, and the sheep bed slatted plate is located above the cover.

[0014] A plurality of suspension devices are arranged at both ends of the track, and the suspension devices include a hanging rail pulley, which is slidably arranged in the track, a pulley bracket is arranged at the lower end of the hanging rail pulley, and a third fixed pulley is installed at the bottom end of the pulley bracket, and the traction rope is passed around the third fixed pulley.

[0015] The pulley brackets between the multiple suspension devices are connected by connecting ropes, and a fixing block is fixed on the corresponding track, and the end of the connecting rope is fixed on the fixing block.

[0016] A travel switch is installed on the cover plate at the outlet side of the manure collecting channel, and a travel switch trigger is installed on the corresponding traction rope and close to the front side of the manure scraping plate assembly.

[0017] The utility model provides an automatic manure scraping device for a sheep shed, which has the following technical effects:

[0018] 1) The travel switch can be used to control the manure scraper assembly to stop automatically in time, without the need for workers to go back and forth to stop the machine, thus saving workers' labor intensity; at the same time, it also avoids the extreme pulling caused by the motor not stopping in time.

[0019] 2) Tracks and covers are installed above the traction rope to prevent the traction rope from being corroded. The inclined setting of the cover ensures that sheep manure and urine can fall smoothly into the manure collection channel.

[0020] 3) By setting up a suspension device, the traction rope can be prevented from falling to the ground and long-term dragging friction can be avoided; by setting up an iron oil tank at the groove wheel, it can be used to lubricate the traction rope.

[0021] 4) Through two sets of groove wheels and four sets of first fixed pulleys, two sets of scraper assemblies can be driven to scrape and retreat in turn at the same time, that is, one set of scraper assemblies scrapes the feces from the feces collection channel to the feces collection tank; the other set of scraper assemblies returns to the starting point of the feces collection channel. One set of scraper assemblies returns after scraping the feces; the other set of scraper assemblies scrapes the feces. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] like Figure 1 As shown, an automatic manure scraping device for a sheep shed includes a manure collecting channel 2, and a manure collecting tank 1 is arranged at the outlet side of the manure collecting channel 2. A manure scraping plate assembly 5 is placed in the manure collecting channel 2 and connected to a traction rope 8 (wire rope). The traction rope 8 is driven by a traction device.

[0035] like Figure 1 As shown, the traction equipment includes fixed seats 4 respectively fixed at both ends of the outer side of the building body formed by the manure collecting channel 2 and the manure collecting tank 1. The fixed seats 4 are cement columns. In this application, there are two groups of fixed seats 4 on each side, and each fixed seat 4 is installed with a group of first fixed pulleys 3. The traction rope 8 passes around the four groups of first fixed pulleys 3 and then wraps around the two groups of groove wheels 13 to form a ring loop. The two groups of groove wheels 13 are rotatably installed on the bracket, and one group of groove wheels 13 is connected to the output end of the gear reduction box 14, and the input section of the gear reduction box 14 is connected to the motor 11 through the belt transmission mechanism 10.

[0036] When the motor 11 is started, the motor 11 drives the gear reduction box 14 to work through the belt transmission mechanism 10, and the gear reduction box 14 drives a groove wheel 13 to rotate, and the second groove wheel 13 is driven to rotate synchronously through the traction rope 8. During the rotation of the traction rope 8 with the two groove wheels 13, the traction ropes 8 in the two manure collection channels 2 are pulled and moved, so that the manure scraper assembly 5 on one side scrapes the manure from the manure collection channel 2 to the manure collection tank 1, and the manure scraper assembly 5 on the other side returns to the starting point of the manure collection channel 2. When the motor 11 is reversed, the manure scraper assembly 5 on one side retreats back to the starting point of the manure collection channel 2 after scraping the manure; the manure scraper assembly 5 on the other side starts from the starting point of the manure collection channel 2 and scrapes the manure to the manure collection tank 1.

[0037] Through this arrangement, the mechanical transmission is made more efficient, stable and reliable, and the traction rope 8 pulls the manure scraper assembly 5 more powerfully, so that more manure can be easily scraped out.

[0038] like Figure 2-6 As shown, the manure scraper assembly 5 includes a manure scraper 7, and the upper end of the manure scraper 7 is provided with a notch (at Figure 5In the tilted state, the lower bottom surface of the notch is parallel to the ground). A movable block 16 is rotatably installed at each notch, and the movable blocks 16 on the left and right are fixedly connected to the connecting bracket 18. The connecting bracket 18 is a diamond frame, and the front and rear ends of the diamond frame are fixed with connecting holes 26, which are used to connect with the traction rope 8. Two legs 19 (travel wheels) with a second fixed pulley are rotatably installed on the back side of the scraper, and the legs 19 are symmetrically spaced on the left and right.

[0039] like Figure 5-6 As shown, when scraping manure, the lower end of the scraper plate 7 is in contact with the ground and is at an angle of 30°-45° to the ground, so that the upper end of the scraper plate 7 can scrape manure while being pulled by the traction rope 8; when the scraper plate returns to the starting end of the manure collecting channel 2, the upper end of the scraper plate is pulled by the traction rope 8, causing the lower end of the scraper plate 7 to be away from the ground and return without friction, thereby reducing the no-load resistance.

[0040] like Figure 2 , Figure 8 As shown, the four corners of the manure scraper 7 are respectively fixedly mounted with support arms 17 consisting of a telescopic rod 22, a spring 21 and a bearing universal wheel 20. The telescopic rod 22 is sleeved by two supporting rods and connected by an internal spring. By providing the manure scraper support arm 17, the manure scraper 7 can be guided, the collision between the manure scraper 7 and the wall of the manure collecting channel 2 can be reduced, and the manure scraper 7 can be prevented from being stuck in the manure collecting channel 2.

[0041] Preferably, if Figure 1 As shown, an iron oil tank 12 is installed just below the groove wheel 13, and the oil tank 12 can immerse the traction rope 8 after being filled with lubricating oil. Through this arrangement, the traction rope 8 is continuously maintained by lubricating oil, and the traction rope 8 runs more smoothly, reducing mechanical wear.

[0042] Preferably, if Figure 5 As shown, a track 24 is fixed at a suitable position above the manure collecting channel 2 and the manure collecting pool 1, and a cover plate 23 is fixed on the left and right sides of the track 24, and the traction rope 8 is located below the cover plate 23. The ends of the two cover plates 23 away from the track 24 are lower. The sheep bed slatted plate is horizontally fixed just above the cover plate 23, and the sheep bed slatted plate and the cover plate 23 partially overlap on the horizontal projection plane. When the sheep urine falls from the sheep bed slatted plate, it first flows from the sheep bed slatted plate to the cover plate 23, and then flows from the cover plate 23 to the manure collecting channel 2. In this way, it is ensured that the sheep manure and urine fall smoothly into the manure collecting channel 2, and it is ensured that the sheep manure and urine do not contact the traction rope 8, thereby avoiding corrosion of the traction rope 8.

[0043] Preferably, if Figure 1As shown, the travel switch 15 is installed on the cover plate 23 at the outlet side of the manure collecting channel 2, and the travel switch trigger 6 is fixed on the traction rope 8 and is located on the manure scraping side close to the manure scraping board assembly 5. Through this arrangement, the manure scraping board assembly 5 can trigger the travel switch 15 to automatically shut down the motor 11 after reaching the manure collecting tank 1, so as to avoid the traction rope 8 being pulled to the limit and broken due to the untimely stopping of the motor 11.

[0044] Preferably, if Figure 1 , Figure 5 As shown, multiple suspension devices 9 are respectively provided at both ends of the track 24 along the length direction. Each suspension device 9 includes a hanging rail pulley 25, which is slidably arranged in the track 24, and a pulley bracket 27 is arranged at the lower end of the hanging rail pulley 25. A third fixed pulley 28 is installed at the bottom end of the pulley bracket 27, and the traction rope 8 is passed around the third fixed pulley 28. In addition, fixed blocks 29 are respectively installed at both ends of the track 24 along the length direction, and a connecting rope 30 (using nylon line) connects the pulley brackets 27 on the multiple suspension devices 9 at each end of the track 24. The multiple suspension devices 9 can be retracted by pulling the connecting rope 30 at the end of the track 24, and the supporting stroke of the traction rope 8 can be controlled by the length of the connecting rope 30 and the number of the suspension devices 9. Through this arrangement, it is ensured that the traction rope 8 always works in a suspended state, and the suspension device 9 does not affect the scraping work, so as to prevent the traction rope 8 from sagging in the middle section of the dung collecting channel 2 and rubbing on the ground for a long time to cause wear.
