Technical Field

[0001] This utility model belongs to the field of livestock breeding environmental sanitation technology, specifically a pigpen manure cleaning device. Background Technology

[0002] In modern animal husbandry, the efficiency of pigpen manure removal directly impacts the hygiene and production efficiency of farms. Currently, there are several devices available for cleaning pigpen manure, typically using scrapers, conveyor belts, or suction devices to collect and transfer the manure. However, these devices have limitations in practical application, such as complex mechanical structures, high maintenance costs, and poor adaptability to pigpens of different sizes. Furthermore, some devices are prone to leaving manure residue during the cleaning process, resulting in less than ideal cleaning outcomes.

[0003] For example, an existing pigpen manure cleaning device uses a chain-driven scraper structure, which mainly includes a drive motor, a chain drive mechanism, and a scraper assembly. The scraper assembly is connected to the drive motor via a chain and can reciprocate on the ground to push the manure into the collection trough. However, this device requires frequent adjustments to the scraper height during use, and the chain drive mechanism is susceptible to corrosion and wear, affecting the device's service life. These findings indicate that there is still room for improvement in the mechanical structure design of existing technologies.

[0004] Therefore, we have made improvements to this and proposed a pigsty manure cleaning device. Utility Model Content

[0012] As a preferred technical solution of this application, tensioning devices are provided on both sides of the driven wheel. The tensioning device includes a tensioning wheel and an adjusting screw. The tensioning wheel is connected to one end of the adjusting screw through a bearing.

The spring 4 is sleeved on the outside of the support rod 3, and both ends of the spring 4 are fixedly connected to the scraper 1 and the support rod 3, respectively. The hinge point between the support rod 3 and the scraper 1 is located at the bottom edge of the scraper 1. The length of the support rod 3 is designed according to the unevenness of the ground. The elastic coefficient of the spring 4 is determined by calculation to ensure that the scraper 1 can maintain flexible contact with the ground under different ground conditions. The hinge structure of the support rod 3 adopts a pin connection. The pin passes through the holes on the support rod 3 and the scraper 1 and is fixed by a cotter pin to ensure a firm connection and easy disassembly and assembly.

[0026] The conveying assembly includes a conveyor belt 5, a drive pulley 6, a driven pulley 7, and a drive unit. The drive pulley 6 and driven pulley 7 are located at opposite ends of the conveyor belt 5. The drive pulley 6 is rotated by the drive unit. The surface of the conveyor belt 5 has multiple grooves evenly distributed along its length. The inner walls of the grooves are coated with an anti-slip coating, formed by a spraying process. The coating thickness is 0.5mm to 1mm, and the material used is polyurethane. The drive pulley 6 and driven pulley 7 are mounted on the frame via bearings. The inner ring of the bearing is interference-fitted with the axle, while the outer ring is clearance-fitted with the mounting base on the frame. The mounting base is fixed to the frame with bolts. The drive unit includes a motor and a reducer. The output shaft of the motor is connected to the input end of the reducer via a coupling. The output end of the reducer is connected to the axle of the drive pulley 6 via a key. The reducer housing is fixed to the frame with bolts. The bottom of the frame has multiple support feet, the height of which can be adjusted using adjusting nuts.

[0027] The linkage mechanism includes a drive shaft 8 and a connecting rod 9. One end of the drive shaft 8 is fixedly connected to the output end of the drive device, and the other end is hinged to the top of the scraper 1 via the connecting rod 9.

The surface of the tensioning pulley 11 contacts the inner side of the conveyor belt 5. The tension of the conveyor belt 5 is adjusted by rotating the adjusting screw 12 to change the position of the tensioning pulley 11. The tensioning pulley 11 is made of cast iron and its surface is phosphated to improve wear resistance.

[0029] The front end of the scraper 1 is equipped with a guide plate 10. The bottom end of the guide plate 10 forms a certain inclination angle with the ground, which is 30° to 45°. The surface of the guide plate 10 is coated with a wear-resistant coating, which is formed by thermal spraying. The coating thickness is 0.3mm to 0.5mm, and the material is tungsten carbide. The guide plate 10 is fixed to the front end of the scraper 1 with bolts. The number of bolts is designed according to the size of the guide plate 10. The bolt specification is M8×20, and the bolt heads are countersunk to avoid protruding parts affecting use.

[0030] The equipment operates as follows: After the motor starts, it transmits power to the drive wheel 6 via a reducer. The drive wheel 6 drives the conveyor belt 5 to rotate, and the movement of the conveyor belt 5 transports the feces from the cleaning area of ​​the scraping assembly to the designated location. Simultaneously, the drive shaft 8 drives the connecting rod 9 through a linkage mechanism. The movement of the connecting rod 9 causes the scraper 1 to swing back and forth. The swinging of the scraper 1 scrapes and cleans the ground through the elastic cleaning strip 2. The elastic cleaning strip 2 maintains flexible contact with the ground. The support rod 3 and spring 4 allow the scraper 1 to adapt to uneven ground conditions, thus ensuring effective cleaning. During the cleaning process, the guide plate 10 guides the feces onto the conveyor belt 5. The grooves and anti-slip coating on the surface of the conveyor belt 5 prevent the feces from slipping during transport. When the conveyor belt 5 becomes slack, the tension wheel 11 is adjusted by rotating the adjusting screw 12 to restore the tension of the conveyor belt 5.

[0031] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0032] First, during the initial installation of the pigpen manure cleaning equipment, the entire device needs to be placed in the area to be cleaned, and the level of the equipment is ensured by adjusting the height of the support feet at the bottom of the frame. The height of the support feet can be adjusted by rotating the adjusting nuts to accommodate different ground inclinations. Then, depending on the specific conditions of the pigpen floor, the height of scraper 1 is adjusted by sliding the positioning blocks along the guide grooves on both sides of the top connecting bracket of scraper 1. After the positioning blocks are fixed in different positions on the guide grooves with bolts, the initial height setting of scraper 1 is completed. This step ensures that the initial contact state between scraper 1 and the ground meets the cleaning requirements.

[0033] Next, the motor is started, and its power is transmitted to the drive wheel 6 through the reducer. The drive wheel 6 drives the conveyor belt 5 to rotate. The grooved design and anti-slip coating on the surface of the conveyor belt 5 effectively increase the friction between the feces and the conveyor belt 5, thus preventing the feces from slipping during transport. At the same time, the drive shaft 8 drives the connecting rod 9 through a linkage mechanism. Both ends of the connecting rod 9 are equipped with spherical hinge joints, and the connections between the connecting rod 9 and the drive shaft 8 and the scraper 1 are all made of bearings. This design reduces the frictional resistance during movement, allowing the scraper 1 to swing back and forth smoothly. The swinging of the scraper 1 cleans the ground through the elastic cleaning strip 2. The elastic cleaning strip 2 maintains flexible contact with the ground, avoiding damage to the ground or incomplete cleaning caused by hard contact.

[0034] During the cleaning process, the support rod 3 and spring 4 in the adjustment assembly play a crucial role. One end of the support rod 3 is hinged to the bottom of the scraper 1, and the other end contacts the ground. The spring 4 is sleeved on the outside of the support rod 3, with its two ends fixedly connected to the scraper 1 and the support rod 3, respectively. When the equipment operates on uneven ground, the elasticity of the spring 4 automatically adjusts the contact state between the scraper 1 and the ground, ensuring that the elastic cleaning strip 2 always remains in close contact with the ground, thereby achieving an adaptive cleaning effect. Furthermore, the elastic cleaning strip 2 consists of multiple detachable cleaning units, each connected to the scraper 1 via a snap-fit ​​structure. In actual use, if a cleaning unit becomes worn, it can be individually removed from the scraper 1 and replaced without replacing the entire elastic cleaning strip 2. This not only reduces maintenance costs but also extends the overall service life of the scraping assembly.

[0035] As the feces are pushed by the scraper 1 to the guide plate 10, the guide plate 10 is tilted at an angle of 30° to 45°. Its surface is coated with a wear-resistant material, further reducing feces adhesion and ensuring smooth sliding onto the conveyor belt 5. The guide plate 10 is bolted to the front end of the scraper 1, with countersunk bolt heads to prevent protruding parts from interfering with equipment operation. The conveyor belt 5 operates continuously under the drive of the drive wheel 6 and the driven wheel 7, transporting the feces to the designated collection area.

[0036] When the conveyor belt 5 becomes loose after prolonged operation, it can be adjusted using a tensioning device. The tensioning device includes a tensioning wheel 11 and an adjusting screw 12. One end of the adjusting screw 12 is connected to the tensioning wheel 11, and the other end passes through the frame and is locked with a nut. By rotating the adjusting screw 12, the position of the tensioning wheel 11 is changed, thereby restoring the tension of the conveyor belt 5. The adjusting screw 12 adopts a trapezoidal thread design with a pitch of 2mm and a screw diameter of 12mm. Combined with a hexagonal nut and anti-loosening washers, it ensures the stability and reliability of the tensioning device.

[0037] In summary, this equipment achieves efficient cleaning and transfer of pig manure through the coordinated operation of the scraping, conveying, and adjusting components. The flexible contact between the elastic sweeping strip 2 and the ground, the adaptive adjustment function of the support rod 3 and spring 4, and the anti-slip design of the conveyor belt 5 collectively ensure the continuity and stability of the cleaning operation. Meanwhile, the modular design of each component and its easy-to-disassemble structure significantly reduce the difficulty and cost of equipment maintenance, and improve its adaptability to pigpens of different sizes.
