Description

Technical Field

[0001] The utility model relates to the technical field of chicken manure cleaning, in particular to a chicken manure cleaning device. Background Art

[0002] In the process of breeding poultry such as broilers, chicks and laying hens, the current breeding equipment is to isolate the chicken cages in layers, and set a chicken manure conveyor belt at the bottom of each breeding layer. A large amount of chicken manure produced by the chickens in the cages falls on the chicken manure conveyor belt below, and after gradually accumulating to a certain amount, the chicken manure conveyor belt is controlled to operate in one direction to collect and clean the excrement of the poultry during the breeding process. The chicken manure on the chicken manure conveyor belt is collected and transported to one side, and then processed in a unified and centralized manner, thereby facilitating the recycling and utilization of chicken manure. While generating certain economic benefits, chicken manure recycling can reduce the content of harmful gases such as ammonia in the chicken house, keep the breeding environment clean and sanitary, and reduce the risk of health hazards to chickens, thereby ensuring food quality and safety.

[0003] Common methods of cleaning chicken manure include scraping. A Chinese patent document disclosed a manure scraper mechanism on December 9, 2021. The patent publication number is CN216392626U. The mechanism uses a tension spring to control the tensioning angle of the scraper plate and the rotating shaft relative to the manure stop belt. After the scraper plate is in contact with the manure stop belt, it takes away the chicken manure on the manure stop belt. Therefore, the device can effectively prevent the chicken manure left on the manure belt from being brought into the cage and causing manure accumulation in the cage, and can also reduce unnecessary labor caused by manual cleaning.

[0004] This method of adjusting the tension of the scraper can clean most of the chicken manure on the chicken manure conveyor belt. However, when scraping the chicken manure, both the dry and undried chicken manure have strong adhesion, and the surface of the chicken manure conveyor belt will be covered with residual chicken manure. This part of the chicken manure is difficult to be completely scraped off by the scraper, and these residues may gradually accumulate in subsequent use, increasing the difficulty of cleaning.

[0013] Furthermore, a collection box is provided at the bottom of the scraping mechanism and the cleaning mechanism.

[0014] In summary, the beneficial effects brought by the utility model are:

[0015] 1.

After most of the chicken manure on the chicken manure conveyor belt is cleaned, considering the material of the chicken manure conveyor belt and the adhesion of the chicken manure, there will still be chicken manure with strong adhesion that is difficult to be completely cleaned by scraping. Therefore, in the direction of chicken manure transmission, the chicken manure conveyor belt after the chicken manure has been scraped by the scraper is then cleaned for the second time by the cleaning mechanism to process the chicken manure coated on the chicken manure conveyor belt by the scraper or to further clean the chicken manure conveyor belt.

[0016] 2. Since the dry chicken manure on the surface of the chicken manure conveyor belt will still remain if it is only scraped off, use the spray hole to connect the water pipe, spray an appropriate amount of water on the surface of the chicken manure conveyor belt after the scraping operation, first soften the chicken manure adhesion layer on the chicken manure conveyor belt, and use water to clean the chicken manure conveyor belt, and then the brush plate in the cleaning mechanism will reciprocate along the width direction of the chicken manure conveyor belt. The bristles on the brush plate can better wipe off the residual chicken manure, so as to achieve the purpose of further cleaning the residual chicken manure on the chicken manure conveyor belt.

[0017] 3. The nozzle is set between the scraper and the brush plate. When the chicken manure conveyor belt is running slowly, the nozzle is facing the surface of the chicken manure conveyor belt. Before the brush plate cleans the residual chicken manure, spray an appropriate amount of water on the chicken manure conveyor belt. Washing with water and wiping with the brush plate can effectively remove the residual chicken manure on the chicken manure conveyor belt. The brush plate can intercept most of the water attached to the chicken manure conveyor belt while cleaning, avoiding the splashing of sewage and the increase of humidity in the chicken house caused by the chicken manure conveyor belt running to the top of the chicken cage, thereby reducing the breeding of bacteria and parasites.

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the embodiments.

[0026] Example 1

[0027] like Figures 1 to 6As shown, a chicken manure cleaning device includes a scraping mechanism 1 and a cleaning mechanism 2. The scraping mechanism 1 and the cleaning mechanism 2 are sequentially arranged on one side of a chicken manure conveyor belt 6 along the chicken manure conveying direction. The scraping mechanism 1 includes a rotating shaft 11 and a scraper 12 axially arranged on the rotating shaft 11. A tensioning mechanism 3 is arranged at the end of the rotating shaft 11. The tensioning mechanism 3 is used to fit the end of the scraper 12 to the surface of the chicken manure conveyor belt 6. The scraping mechanism 1 and the cleaning mechanism 2 are sequentially arranged along the conveying direction of the chicken manure conveyor belt 6, wherein the scraper 12 exerts pressure on the chicken manure conveyor belt 6 under the action of the tensioning mechanism 3. Therefore, during implementation, the scraping mechanism 1 is arranged at the end of the chicken manure conveyor belt 6, and the upper end of the scraper 12 abuts against the outer surface of the chicken manure conveyor belt 6 outside the roller 8. With the operation of the chicken manure conveyor belt 6, the chicken manure collected on the chicken manure conveyor belt 6 can be gradually scraped off. Most of the chicken manure is scraped off the chicken manure conveyor belt 6 under the action of the scraper 12, and falls downward along the scraper 12 for collection. The scraping mechanism 1 can be rotatably installed on one side of the existing chicken manure conveyor belt 6 by installing a rotating shaft 11 connector at both ends of the rotating shaft 11, that is, the scraping mechanism 1 is installed in the chicken manure collection area on one side of the automated breeding equipment. The installation method includes two rotating shaft 11 connectors being relatively installed on the two side walls of the chicken manure collection area, or as Figure 1 The shown rotating shaft 11 connector is installed on a side plate, and the side plate is installed on the iron frame of the breeding equipment by welding or the like, so it can be applied to some existing breeding equipment, thereby improving its applicability.

[0028] In this embodiment, a mounting block 13 is provided on the rotating shaft 11, and a scraper 12 is installed on the mounting block 13. A nozzle 4 is provided at intervals along the axial direction of the rotating shaft 11 on one side of the mounting block 13 facing the chicken manure conveyor belt 6. The water spraying hole of the nozzle 4 faces the chicken manure conveyor belt 6, and the nozzle 4 is located between the scraper 12 and the cleaning mechanism 2. The nozzles 4 are evenly arranged along the mounting block 13, so that the water from the nozzles 4 can be evenly sprayed in the width direction of the chicken manure conveyor belt 6. The external water pipe of the nozzle 4 evenly sprays the chicken manure conveyor belt 6 after the chicken manure is scraped off, and an appropriate amount of water is sprinkled on the chicken manure conveyor belt 6. The cleaning mechanism 2 of the subsequent process cleans the residual chicken manure layer on the chicken manure conveyor belt 6, and intercepts the sewage to prevent the sewage from gathering and dripping on the breeding equipment, causing the equipment to rust and the environment.

[0029] Example 2

[0030] like Figures 1 to 6As shown, the scraping mechanism 1 and the cleaning mechanism 2 are sequentially arranged on one side of the chicken manure conveyor belt 6 along the chicken manure conveying direction. The present embodiment is different from the embodiment 1 in that the cleaning mechanism 2 includes a brush plate 21, a first mounting plate 22 and a second mounting plate 23, and a first limit block 221 and a driving motor 222 mounted on the first mounting plate 22, and a second limit block 231 is installed on the second mounting plate 23. The two ends of the brush plate 21 in the length direction are connected with a first slide bar 211 and a second slide bar 212, the first slide bar 211 is slidably penetrated on the first limit block 221, and the second slide bar 212 is slidably penetrated on the second limit block 231, and the transmission shaft of the driving motor 222 passes through the first mounting plate 22 and is fixedly connected to the turntable 24, and a rocker 25 is arranged between the turntable 24 and the first slide bar 211, and one end of the rocker 25 is eccentrically hinged to the turntable 24, and the other end is hinged to the first slide bar 211.

[0031] The first mounting plate 22 is mounted on one end of the chicken manure conveyor belt 6 in the width direction, and the second mounting plate 23 is mounted on the other end of the chicken manure conveyor belt 6 in the width direction. The first limit block 221 and the second limit block 231 are fixedly mounted on the same side of the first mounting plate 22 and the second mounting plate 23, respectively. The brush plate 21 is connected to the first slide bar 211 and the second slide bar 212 through both ends. The first slide bar 211 and the second slide bar 212 pass through the first limit block 221 and the second limit block 231, respectively, so that the brush plate 21 can reciprocate, and the residual chicken manure on the chicken manure conveyor belt 6 can be better wiped off under the reciprocating motion of the brush plate 21. The reciprocating motion is realized by respectively hingedly connecting the first slide bar 211 and the turntable 24 at both ends of the rocker 25 to convert the rotary motion into the reciprocating motion.

[0032] In a specific implementation, the first slide bar 211 and the second slide bar 212 are threadedly connected to the brush plate 21, and one end of the first slide bar 211 and the second slide bar 212 connected to the brush plate 21 is threadedly connected to the first locking nut 213, and one side of the first locking nut 213 abuts against the side wall of the brush plate 21. Figure 5 As shown, one end of the first slide rod 211 away from the brush plate 21 is threadedly connected to the connector 26, and one end of the first slide rod 211 connected to the connector 26 is threadedly connected to the second locking nut 214, one side of the second locking nut 214 abuts against the side wall of the connector 26, a first column 241 is eccentrically arranged on the turntable 24, a second column 261 is fixed on the connector 26, and both ends of the rocker arm 25 are hinged to the first column 241 and the second column 261 respectively.

[0033] Both ends of the first slide bar 211 are provided with threads, and threaded holes are provided at both ends of the brush plate 21 and one end of the connector 26. After the first slide bar 211 is threadedly connected, the first locking nut 213 and the second locking nut 214 are rotated so that the first slide bar 211 and the brush plate 21 are locked to prevent the brush plate 21 from rotating or falling loose during reciprocating motion, so that the brush plate 21 can stably wipe the residual chicken manure on the surface of the chicken manure conveyor belt 6.

[0034] In order to make the brush plate 21 fit the conveyor belt better, and when the chicken manure conveyor belt 6 runs slowly, the reciprocating motion rate is adjusted so that the brush plate 21 can brush the same area of ​​the chicken manure conveyor belt 6 multiple times. The cross-section of the brush plate 21 is arc-shaped, and bristles are arranged on the arc-shaped surface of the brush plate 21. The arc-shaped brush plate 21 can increase the contact area with the chicken manure conveyor belt 6. Compared with the line contact between the scraper 12 and the chicken manure conveyor belt 6, the surface contact between the brush plate 21 and the chicken manure conveyor belt 6 can also better wipe off and intercept the chicken manure and sewage on the chicken manure conveyor belt 6, so that the dirt can be collected.

[0035] Example 3

[0036] like Figures 1 to 5 As shown, this embodiment is different from the above embodiment in that the tensioning mechanism 3 includes an annular sleeve 31 sleeved on the end of the rotating shaft 11, and a locking bolt 311 is radially penetrated on the outer side surface of the annular sleeve 31. The annular sleeve 31 and the rotating shaft 11 are fixed by the locking bolt 311. The outer side surface of the annular sleeve 31 extends radially to form a limiting plate 32. The limiting plate 32 has a strip hole 321. An adjusting rod 33 is movably penetrated in the strip hole 321, and a spring 34 is sleeved on the adjusting rod 33.

[0037] In this embodiment, a third adjusting nut 331 is threadedly installed at one end of the adjusting rod 33, the spring 34 is located between the limiting plate 32 and the third adjusting nut 331, and a fixing block 35 is threadedly connected to one end of the adjusting rod 33, and the adjusting rod 33 is fixedly installed on the side wall of the transmission equipment or the breeding equipment through the fixing block 35.

[0038] The spring 34 applies force to the limit plate 32 so that the scraper 12 can fit the surface of the chicken manure conveyor belt 6. For example, according to the setting position of the limit plate 32, when the limit plate 32 is set to be away from the direction of the chicken manure conveyor belt 6, if the fixed block 35 is set at the bottom end of the adjusting rod 33, the spring 34 is set between the bottom of the limit plate 32 and the fixed block 35; if the fixed block 35 is set at the top of the adjusting rod 33, the spring 34 is set between the top of the limit plate 32 and the fixed block 35, and the third adjusting nut 331 is set between the fixed block 35 and the spring 34. By rotating the position of the third adjusting nut 331, the scraper 12 is controlled to fit the surface of the chicken manure conveyor belt 6.

[0039] Example 4

[0040] like Figures 1 to 5 As shown, the top of the scraper 12 in the scraping mechanism 1 is against the upper half of the roller 8, and the cleaning mechanism 2 is arranged at the lower half of the roller 8. The bottom of the scraper 12 has a groove, and the scraper 12 is inserted into the mounting block 13 and fixed by mounting screws on one side. The material of the scraper 12 is selected from rubber, plastic or polyurethane, etc. The length of the scraper 12 matches the width of the chicken manure conveyor belt 6. The scraper 12 and the rotating shaft 11 can be cut according to the width of the chicken manure conveyor belt 6. The rotating shaft 11 is made of a metal pipe. The scraper 12 is in close contact with the surface of the chicken manure conveyor belt 6 under the action of the tensioning mechanism 3, and the water spray hole of the nozzle 4 faces the chicken manure conveyor belt 6, and the nozzle 4 is located between the scraper 12 and the cleaning mechanism 2. The first mounting plate 22 and the second mounting plate 23 are respectively installed on the breeding equipment according to the position and size of the roller shaft 8. The driving motor 222 can be installed on the side of the scraper 12 close to the roller shaft 8, so as to prevent the scraped chicken manure from falling on the device and causing pollution. The length of the first slide bar 211 and the second slide bar 212 can ensure that the brush plate 21 does not affect the reciprocating motion and does not separate from the two limit blocks when moving. The two slide bars are connected to the brush plate 21, the connecting head 26, etc. in a threaded connection manner, which is convenient for disassembly and assembly, and the brush plate in the cleaning mechanism 2 can be cleaned after disassembly and assembly.

[0041] like Figure 5 As shown, the two ends of the rocker 25 are hinged to the first column 241 and the second column 261 respectively. The two columns are located on the same side, and the ends of the columns are also threaded and equipped with screw caps 27. When the two ends of the rocker 25 are sleeved on the columns, the screw caps 27 prevent the rocker 25 from falling off.

[0042] An annular sleeve 31 is sleeved on one end of the rotating shaft 11, and a locking bolt 311 is radially penetrated on the outer side surface of the annular sleeve 31. Two to three locking bolts 311 are arranged along the circumference of the annular sleeve 31. The annular sleeve 31 and the rotating shaft 11 are fixed by the locking bolts 311. The outer side surface of the annular sleeve 31 extends radially to form a limiting plate 32. The limiting plate 32 has a strip hole 321. When the rotating shaft 11 is deflected, the limiting plate 32 moves along the strip hole 321 to control the position of the third locking nut 331 on the adjusting rod 33. The spring 34 gives elastic force to the limiting plate 32, and the limiting plate 32 rotates around the rotating shaft together with the rotating shaft 11.

[0043] like Figure 1 and Figure 6As shown, the adjusting rod 33 is fixedly mounted on the side wall of the transmission equipment or the breeding equipment 7 through the fixing block 35, the scraping mechanism 1 is mounted on the breeding equipment 7 through the connectors at both ends of the rotating shaft 11, and the cleaning mechanism 2 is mounted on the breeding equipment 7 or the chicken manure conveying equipment 9 through two mounting plates, so that the cleaning device can be applied to the existing breeding equipment 7 without making too many modifications to the existing breeding equipment 7 or the chicken manure conveying equipment 9. When cleaning chicken manure in multiple breeding layers, a collecting box is provided at the bottom of the scraping mechanism 1 and the cleaning mechanism 2 to collect chicken manure in each layer, or a collecting box 5 is provided only under the cleaning device at the bottom layer. In the specific implementation, considering the installation position of the chicken manure conveying equipment 9, a drying box and / or a sterilizing box is provided at the rear side of the station of the cleaning mechanism 2 to remove water on the chicken manure conveying belt 6 and sterilize the chicken manure conveying belt 6.
