[0002] In recent years, the biological method of treating urban sludge using earthworms has gradually gained social acceptance. This treatment method does not produce secondary pollution and has significant economic benefits. After the sludge is converted into earthworm castings, it can be used as a base material for producing organic fertilizer for forestry products or garden fertilizers. Patent publication number CN220376542U discloses a three-dimensional system for treating urban sludge using earthworms. Specifically, it discloses a feeding device, a conveying device, and a receiving device. The conveying device includes a frame, within which at least two layers of conveying nets are arranged at intervals from bottom to top. It can realize the three functions of feeding, sludge treatment and conveying, and receiving. However, since this solution adopts a single-layer material spreading method, a large amount of material needs to be spread on the conveying net at one time. This results in problems such as excessive thickness of material spread at one time, poor aeration, and poor earthworm fertilization effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a three-dimensional earthworm fattening device that can realize the function of single small-scale material spreading and repeated material spreading multiple times. It has good air permeability to improve the final fattening effect of earthworms. The structure is simple and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional earthworm fattening device, comprising a conveyor network device with multiple layers spaced from bottom to top within a three-dimensional frame. Each conveyor network device includes a drive shaft and a driven shaft at both ends of the three-dimensional frame. One end of the drive shaft is connected to a conveyor network reduction motor.

The conveyor belt is wound between the drive roller and the tension roller, and the upper rollers and lower rollers roll and abut against the upper and lower sections of the conveyor belt, respectively. The output shaft of the belt reduction motor is connected to the drive roller for transmission.

[0006] Furthermore, the front end of the vehicle body is provided with a tensioning frame that can slide along its length, and the tensioning roller is rotatably mounted on the tensioning frame; a tensioning roller adjustment mechanism is provided between the tensioning frame and the vehicle body, the tensioning roller adjustment mechanism includes a vertical plate provided at the front end of the vehicle body, an end plate provided on the tensioning frame in front of the vertical plate, an adjusting screw provided between the end plate and the vertical plate, the two ends of the adjusting screw passing through the end plate and the vertical plate respectively, and adjusting nuts threadedly connected to the adjusting screw at the corresponding positions of the end plate and the vertical plate; a scraper is also provided at the bottom of the front end of the tensioning frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-7This utility model provides a technical solution: a three-dimensional earthworm fattening device, including a three-dimensional frame 1 with multiple layers of conveyor nets 2 arranged from bottom to top. The conveyor nets 2 include a drive shaft 21 and a driven shaft 22 respectively provided at both ends of the three-dimensional frame 1. One end of the drive shaft 21 is connected to a conveyor net reduction motor 24. The conveyor net reduction motors 24 on each layer of conveyor nets 2 are fixed in the motor bracket 3 in sequence. Two sets of sprockets are provided on both sides of the drive shaft 21 and the driven shaft 22 and are connected by chains 5. A conveyor net 23 is provided between the chains 5 on both sides.

[0022] The conveyor net 23 includes an outermost stainless steel mesh 231, with a mesh belt 232 fixed to the inner side of the stainless steel mesh 231. Conveyor net supports 233 are evenly spaced on the inner side of the mesh belt 232, and both ends of each conveyor net support 233 are fixed between the chains 5 on both sides via connecting plates 234. A chain rail 41 is located directly below the upper and lower sections of each chain 5. This chain rail 41 is fixed within the three-dimensional frame 1 by the chain supports 4, and both the upper and lower ends of the chain rail 41 are bent downwards into an arc shape. The stainless steel mesh 231 provides ventilation, the mesh belt 232 supports the stainless steel mesh 231, and the evenly spaced conveyor net supports 233 support and fix the mesh belt 232. Because the conveyor net supports 233 are fixed to the chains 5, it ensures that the conveyor net 23 moves along with the chains 5.

[0023] A baffle device 6 is provided on each side above the conveying device 2 of each layer of conveyor network; the baffle device 6 can reduce the material drop phenomenon of the conveyor network 23; the driven shaft 22 is installed on the three-dimensional frame 1 through the driven shaft tensioning device 25; the tension of the chain 5 can be adjusted through the driven shaft tensioning device 25; the specific structure and working principle of the baffle device 6 and the driven shaft tensioning device 25 are existing technologies, and will not be described in detail in this solution.

[0024] The three-dimensional frame 1 is equipped with a straight slide rail 7 above the conveyor belt 2. A material spreading trolley 8 is mounted on the straight slide rail 7. The material spreading trolley 8 includes a body 81, which is rolled on the straight slide rail 7 by wheels 82 at its bottom. The material spreading trolley 8 is equipped with a travel reduction motor 83 that can drive the wheels 82 to rotate and move. A conveyor belt 84 is mounted on the body 81, and a belt reduction motor 89 that can drive the conveyor belt 84 to rotate is also mounted on the body 81.

[0025] Working principle:

[0026] Material is supplied to the spreading cart 8 above the conveyor network 2 by an external feeding device. The material supplied by the external feeding device falls onto the conveyor belt 84 of the spreading cart 8. The belt reduction motor 89 drives the conveyor belt 84 to rotate, so that the material on the conveyor belt 84 is spread onto the conveyor network 23. At the same time, the traveling reduction motor 83 drives the spreading cart 8 to move back and forth along the straight slide 7. The conveyor belt 84 can rotate in both forward and reverse directions, so that the material on the conveyor belt 84 is evenly spread across the entire conveyor network 23. A layer of earthworm seedlings is introduced onto the material on the conveyor net 23. When the earthworms have almost finished eating the feed (sludge) (earthworms have the habit of crawling towards new feed), the above-mentioned feeding action is repeated again. The earthworms continue to eat the feed and fatten up. The above process is repeated to improve the final fattening effect of the earthworms. After a certain period of time, the earthworms digest the sludge and fatten themselves up while producing earthworm castings. The conveyor net reduction motor 24 is started to drive the drive shaft 21 to rotate. After the conveyor net 23 rotates, the earthworm castings and the fattened earthworms are forced to fall into the external receiving device.

[0027] Furthermore, the upper end of the vehicle body 81 is provided with multiple upper rollers 85 along its length, the bottom end of the vehicle body 81 is provided with multiple lower rollers 86 along its length, the front end of the vehicle body 81 is provided with a tension roller 87, and the rear end of the vehicle body 81 is provided with a drive roller 88. The conveyor belt 84 is wound between the drive roller 88 and the tension roller 87, and the upper rollers 85 and lower rollers 86 roll and abut against the upper and lower sections of the conveyor belt 84, respectively. The output shaft of the belt reduction motor 89 is connected to the drive roller 88. The front end of the vehicle body 81 is provided with a tension frame 810 that can slide along its length, and the tension roller 87 is rotatably mounted on the tension frame 810. A tension roller adjustment mechanism 9 is provided between the tension frame 810 and the vehicle body 81. The tension roller adjustment mechanism 9 includes a vertical plate 91 at the front end of the vehicle body 81, and the tension frame 810 is positioned on the vertical plate 91. An end plate 92 is provided at the front of the tensioning frame 810. An adjusting screw 93 is provided between the end plate 92 and the vertical plate 91. The two ends of the adjusting screw 93 pass through the end plate 92 and the vertical plate 91 respectively, and adjusting nuts 94 are threadedly connected to the adjusting screw 93 at the corresponding positions of the end plate 92 and the vertical plate 91. A scraper 813 is also provided at the bottom of the front end of the tensioning frame 810. The upper roller 85 and the lower roller 86 provided along the length of the vehicle body 81 provide stable support for the conveyor belt 84. The tensioning roller 87 tensions the conveyor belt 84. By loosening the adjusting nut 94, the tensioning frame 810 can move horizontally relative to the vehicle body 81. After the tensioning roller 87 on the tensioning frame 810 is adjusted, the adjusting nuts 94 at the positions of the vertical plate 91 and the end plate 92 are tightened. The adjusting nut 94 on the adjusting screw 93 limits the horizontal movement of the tensioning frame 810.

[0028] Furthermore, both sides of the vehicle body 81 are provided with edge-blocking devices. The edge-blocking devices include columns 811 fixed to the side of the vehicle body 81, and each column 811 is provided with an inwardly inclined edge plate 812. The bottom end of the edge plate 812 contacts the conveyor belt 84. The edge-blocking devices reduce the phenomenon of material dropping when the conveyor belt 84 is conveying materials.

[0029] The earthworm fattening three-dimensional device disclosed in this embodiment uses a belt-driven reduction motor 89 to rotate a conveyor belt 84, spreading the material on the conveyor belt 84 onto a conveyor net 23. Simultaneously, a traveling reduction motor 83 drives a spreading trolley 8 to move back and forth along a straight slide 7. The conveyor belt 84 can rotate in both directions, ensuring the material on the conveyor belt 84 is evenly spread across the entire conveyor net 23. Then, a layer of earthworm seedlings is introduced into the material on the conveyor net 23. Once the earthworms have consumed most of the feed (sludge) (earthworms have a tendency to crawl towards new feed), the spreading process is repeated, allowing the earthworms to continue consuming the feed and fattening. This process is repeated to improve the final fattening effect. This earthworm fattening three-dimensional device can achieve single-time small-volume spreading and repeated spreading, thus improving the final fattening effect. It has a simple structure and is flexible and convenient for earthworm fattening.
