Description

Technical Field

[0001] This utility model relates to the field of cow dung processing technology, specifically to an agricultural cow dung drying and processing equipment. Background Technology

[0002] Cow dung is the excrement of cows. After drying, cow dung can be used to make cow dung organic fertilizer, which can loosen the soil, improve soil compaction, integrate trace elements in the soil, enhance soil fertility, and can also be used as a clean energy source for power generation. It has many uses.

[0003] When processing cow manure, a dry-wet separator is typically used to initially dehydrate the fresh manure, controlling its moisture content to 60%–70%, thus laying the foundation for subsequent drying operations. The semi-dry manure is then transported to the feed inlet of a rotary drum dryer via a conveyor belt for secondary drying to achieve the target moisture content. However, because the manure in this moisture content range still retains its stickiness, it is prone to blockage during transport to the feed inlet due to adhesion between the material and the inner wall of the inlet, as well as material compression and accumulation. This leads to unstable feed rates to the rotary drum dryer, directly affecting the overall continuous operation of the drying system. Furthermore, some manure tends to clump and agglomerate during the temporary storage phase before transport and feeding, forming hardened lumps. These lumps cannot fully contact the hot drying air after entering the rotary drum dryer, resulting in uneven drying. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an agricultural cow manure drying and processing equipment to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural cow manure drying and processing device, comprising a base, a support seat and an installation box at the top of the base, a feeding port penetrating the top of the installation box, a drying cylinder rotatably connected to the inner side of the support seat, one end of the drying cylinder extending into the interior of the installation box, a gear ring on one side of the outer surface of the drying cylinder, a motor mounted on one side of the support seat, and a drive shaft extending into the interior of the installation box connected to the output end of the motor, a drive gear meshing with the gear ring fixed on the outer surface of the drive shaft, and a main pulley fixed on one side of the outer surface of the drive shaft; a guide trough fixed inside the installation box, a baffle plate fixed at the bottom of the guide trough, a crankshaft extending into the interior of the drying cylinder fixed inside the installation box, a driven pulley fixed on one side of the outer surface of the crankshaft, and a transmission belt sleeved on the outer surfaces of the main pulley and the driven pulley, a rotating sleeve sleeved on the outer surface of the crankshaft, a connecting rod fixed at the top of the rotating sleeve, and a dredging rod hinged to the top of the connecting rod, and a dispersing rod fixed on the other side of the outer surface of the crankshaft.

[0006] Furthermore, a mounting rod extending into the drying cylinder is fixed to one side of the baffle plate, and a scraper is bolted to the bottom end of the mounting rod, with the bottom of the scraper fixed to the inner wall of the drying cylinder.

[0007] By adopting the above technical solution, since the cow manure that just enters the drying drum is moist, a scraper is installed in the feeding part of the drying drum. When the drying drum rotates, the scraper can scrape off the cow manure adhering to the inner wall, avoiding material residue from clumping and affecting the uniformity of drying. At the same time, the scraper is installed with bolts, which makes it easy to disassemble and replace, improving the convenience of equipment maintenance.

[0008] Furthermore, a heating pipe extends through the other side of the baffle plate, and one end of the heating pipe extends to the back of the mounting box.

[0009] By adopting the above technical solution, the heating pipe is connected to the hot air furnace, which can introduce a continuous and stable hot air into the installation box and drying cylinder, providing a heat source for drying cow dung and ensuring sufficient and stable heat supply during the drying process.

[0010] Furthermore, the inner wall of the drying cylinder is fixed with multiple sets of turning plates, and the turning plates are in the shape of a "7".

[0011] By adopting the above technical solution, multiple sets of "7"-shaped turning plates can continuously lift, turn and disperse the cow manure inside the drying drum as it rotates, thus preventing material accumulation.

[0012] Furthermore, one side of the feed trough extends into the interior of the drying cylinder and is inclined towards the drying cylinder.

[0013] By adopting the above technical solution, by extending one side of the feed chute into the drying cylinder and tilting it, the cow manure can be smoothly guided into the drying cylinder by gravity, avoiding the material from accumulating at the end of the feed chute.

[0014] Furthermore, the unblocking rod is movably connected to the material guide trough, and the top end of the unblocking rod extends into the interior of the feeding port.

[0015] By adopting the above technical solution, the movable connection between the unblocking rod and the guide trough can ensure the stability of its up and down movement and avoid jamming; while the top extends into the inside of the feeding port, it can directly disturb the cow manure in the feeding port, further enhancing the anti-blocking effect and ensuring that the material enters the guide trough smoothly.

[0016] Furthermore, the diameter of the main pulley is larger than the diameter of the driven pulley, and the transmission ratio between the main pulley and the driven pulley is 4:1.

[0017] By adopting the above technical solution, the diameter of the main pulley is larger than that of the driven pulley and the transmission ratio is set to 4:1, which enables the driven pulley to obtain a speed significantly higher than that of the main pulley, thereby driving the crankshaft to rotate at high speed. The high-speed rotating crankshaft not only allows the dispersing rod to more efficiently impact and break up the clumps of cow dung, but also matches the up-and-down movement frequency of the unblocking rod, ensuring that the anti-clogging of the feeding port and the material dispersing work synergistically, laying the foundation for subsequent uniform drying.

[0018] Furthermore, the outer surface of the mounting box is provided with a control panel and a maintenance door, and the motor is electrically connected to the control panel.

[0019] By adopting the above technical solution, the motor can be conveniently started, stopped and rotated through the electrical connection between the control panel and the motor, thereby adjusting the rotation speed of the drying drum and the crankshaft operation status, flexibly adapting to the processing needs of cow manure with different moisture contents; at the same time, the maintenance door on the outer surface of the box can be quickly opened to inspect or clean the internal transmission belt, crankshaft, dispersing rod and other components, greatly reducing the difficulty of equipment maintenance and ensuring long-term stable operation.

[0020] In summary, this utility model has the following beneficial effects: This utility model, by comprising a drive shaft, a main pulley, a driven pulley, a transmission belt, a crankshaft, a rotating sleeve, a connecting rod, a dispersing rod, and a unblocking rod, allows the drive shaft to rotate when the motor rotates. The rotation of the drive shaft causes the drive gear and the main pulley to rotate. The rotation of the drive gear causes the gear ring to drive the drying cylinder to rotate, while the rotation of the main pulley drives the driven pulley to rotate via the transmission belt, thus causing the crankshaft to rotate. During the crankshaft rotation, the unblocking rod continuously moves up and down through the rotating sleeve and connecting rod, thus regulating the feeding process. The dynamic disturbance of the cow dung inside the feed inlet effectively avoids blockage caused by its stickiness, ensuring the continuity of the feeding process and stabilizing the feed rate of the drum dryer. This provides support for the stable operation of subsequent drying operations. The crankshaft rotation directly drives the dispersing rod to rotate at high speed, allowing the cow dung falling into the guide trough through the feed inlet and sliding down to fully contact the dispersing rod. This efficiently breaks up the clumps of cow dung into loose material, significantly increasing the contact area between the cow dung and the drying hot air. This completely solves the problem of uneven drying of lumpy materials and ensures the stability of the quality of the dried cow dung product. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example 1: An agricultural cow dung drying and processing device, such as... Figures 1-6As shown, the system includes a base 1, a support 2 and a mounting box 6 on the top of the base 1, and a feeding port 7 penetrating the top of the mounting box 6. A drying cylinder 3 is rotatably connected to the inner side of the support 2, and one end of the drying cylinder 3 extends into the interior of the mounting box 6. A toothed ring 5 is provided on one side of the outer surface of the drying cylinder 3. A motor 9 is mounted on one side of the support 2, and the output end of the motor 9 is connected to a drive shaft 10 extending into the interior of the mounting box 6. A control panel 8 and a maintenance door are respectively provided on the outer surface of the mounting box 6. The motor 9 is electrically connected to the control panel 8. Through the electrical connection between the control panel 8 and the motor 9, the start / stop and speed of the motor 9 can be easily controlled, thereby adjusting the rotational speed of the drying cylinder 3 and the operating state of the crankshaft 16, flexibly adapting to the processing needs of cow manure with different moisture contents. Simultaneously, the maintenance door on the outer surface of the mounting box 6 can be quickly opened to inspect or clean internal components such as the transmission belt 15, crankshaft 16, and dispersing rod 21, significantly reducing equipment maintenance difficulty and ensuring long-term stable operation. The drive shaft 10... A drive gear 11 that meshes with a gear ring 5 is fixed to the outer surface of the drive shaft 10. A main pulley 14 is fixed to one side of the outer surface of the drive shaft 10. A guide groove 12 is fixed inside the mounting box 6. A baffle plate 13 is fixed to the bottom of the guide groove 12. A crankshaft 16 extending into the drying cylinder 3 is fixed inside the mounting box 6. A driven pulley 17 is fixed to one side of the outer surface of the crankshaft 16. A transmission belt 15 is sleeved on the outer surfaces of the main pulley 14 and the driven pulley 17. A rotating sleeve 18 is fitted onto the surface, and a connecting rod 19 is fixed to the top of the rotating sleeve 18. A dredging rod 20 is hinged to the top of the connecting rod 19. A dispersing rod 21 is fixed to the other side of the outer surface of the crankshaft 16. A heating pipe 24 passes through the other side of the baffle plate 13, and one end of the heating pipe 24 extends to the back of the mounting box 6. The heating pipe 24 is connected to the hot air furnace, which can introduce continuous and stable hot air into the mounting box 6 and the drying cylinder 3 to provide a heat source for drying cow dung and ensure sufficient and stable heat supply during the drying process.

[0026] See Figures 1-3 In the above embodiment, the inner wall of the drying cylinder 3 is fixed with multiple sets of turning plates 4, and the turning plates 4 are in the shape of a "7". When the multiple sets of "7" shaped turning plates 4 rotate with the drying cylinder 3, they can continuously lift, turn and disperse the cow dung in the cylinder to avoid material accumulation.

[0027] See Figure 2 In the above embodiment, one side of the guide trough 12 extends into the interior of the drying cylinder 3 and is inclined towards the drying cylinder 3. By extending one side of the guide trough 12 into the interior of the drying cylinder 3 and inclining it, the cow manure can be smoothly guided into the drying cylinder 3 by gravity, avoiding the material from accumulating at the end of the guide trough 12.

[0028] See Figures 2-3In the above embodiment, the unblocking rod 20 is movably connected to the guide trough 12, and the top end of the unblocking rod 20 extends into the interior of the feeding port 7. The movable connection between the unblocking rod 20 and the guide trough 12 can ensure its stability during up and down movement and avoid jamming. The top end extending into the interior of the feeding port 7 can directly disturb the cow manure in the feeding port 7, further enhancing the anti-blocking effect and ensuring that the material smoothly enters the guide trough 12.

[0029] See Figures 3-4 In the above embodiment, the diameter of the main pulley 14 is larger than the diameter of the driven pulley 17, and the transmission ratio between the main pulley 14 and the driven pulley 17 is 4:1. The larger diameter of the main pulley 14 and the 4:1 transmission ratio enable the driven pulley 17 to achieve a significantly higher rotational speed than the main pulley 14, thereby driving the crankshaft 16 to rotate at high speed. The high-speed rotating crankshaft 16 not only allows the dispersing rod 21 to more efficiently impact and break up the clumps of cow dung, but also matches the up-and-down movement frequency of the unblocking rod 20, ensuring that the anti-clogging of the feeding port 7 and the material dispersing work synergistically, laying the foundation for subsequent uniform drying.

[0030] Example 2: Since the cow dung entering the drying drum is moist, it easily sticks to the inner wall of the drum. Example 2 is an improvement on Example 1. See [link / reference needed]. Figure 2 , Figure 4 and Figure 6 A mounting rod 22 extending into the drying cylinder 3 is fixed to one side of the baffle plate 13, and a scraper 23 is bolted to the bottom end of the mounting rod 22. The bottom of the scraper 23 is fixed to the inner wall of the drying cylinder 3. Since the cow manure that just enters the drying cylinder 3 is moist, a scraper 23 is provided in the feeding part of the drying cylinder 3. When the drying cylinder 3 rotates, the scraper 23 can scrape off the cow manure adhering to the inner wall, avoiding material residue and clumping that affects the uniformity of drying. At the same time, the scraper 23 is bolted, which makes it easy to disassemble and replace, improving the convenience of equipment maintenance.

[0031] The implementation principle of this utility model is as follows: First, the worker connects the heating pipe 24 to the hot air furnace, which introduces a continuous and stable hot air into the installation box 6 and the drying cylinder 3 to provide a heat source for drying cow manure. The semi-dry cow manure, pre-treated by the dry-wet separator, is transported to the feeding port 7, which is set through the top of the installation box 6, by a lifting conveyor. The worker first starts the motor 9 through the control panel 8. The output end of the motor 9 drives the drive shaft 10 to rotate. The output end of the motor 9 drives the drive shaft 10, which extends into the installation box 6, to rotate. The main pulley 14 on the outer surface of the drive shaft 10 rotates synchronously, and drives the driven pulley 17 on the outer surface of the crankshaft 16 to rotate through the transmission belt 15, thereby causing the crankshaft 16 to rotate. When the crankshaft 16 rotates, the rotating sleeve 18 sleeved on its outer surface moves together. The connecting rod 19 fixed at the top of the rotating sleeve 18 drives the unblocking rod 20 hinged at the top to move. The unblocking rod 20 moves up and down continuously, creating dynamic disturbance to the cow manure in the feeding port 7, effectively preventing the semi-dry cow manure from sticking to the inner wall of the feeding port 7 or from being squeezed and accumulated. After being cleared of blockages, the cow manure smoothly falls into the fixed guide trough 12 inside the installation box 6. Guided by gravity, the cow manure slides smoothly down the guide trough 12. During this process, the dispersing rod 21 fixed on the other side of the outer surface of the crankshaft 16 rotates at high speed with the crankshaft 16, rapidly impacting and breaking up the cow manure sliding down the guide trough 12, dispersing the clumped cow manure into loose material. Finally, the loosened cow manure smoothly enters the drying drum 3 through the inclined guide trough 12; the drive gear 11 on the outer surface of the drive shaft 10... The toothed ring 5 on the outer surface of the drying cylinder 3 engages with the inner side of the support base 2, causing the drying cylinder 3 to rotate. Multiple sets of "7"-shaped turning plates 4 on the inner wall of the drying cylinder 3 rotate synchronously with it, thereby turning the cow manure. During the turning process, the cow manure will come into full contact with the hot air. Since the cow manure that just enters the drying cylinder 3 is moist, a scraper 23 is provided in the feeding part of the drying cylinder 3. When the drying cylinder 3 rotates, the scraper 23 can scrape off the cow manure adhering to the inner wall. The cow manure that has been slowly dried will be discharged from the other end of the drying cylinder 3.
