Description

Technical Field

[0001] This invention relates to the field of livestock and poultry manure treatment technology, specifically to a livestock and poultry manure composting and fermentation device. Background Technology

[0002] In the patent application with application announcement number CN117285384A, application publication date of December 26, 2023, entitled "A Harmless Treatment Device for Livestock and Poultry Manure", this invention discloses a harmless treatment device for livestock and poultry manure, belonging to the field of livestock and poultry manure treatment technology. The key points of its technical solution are: a harmless treatment device for livestock and poultry manure, including a separation device, the separation device is composed of a squeezing system and a fermentation filtration system, the squeezing system includes a second shell, the interior of the second shell is provided with a flexible waterproof cloth, multiple sets of squeezing plate bodies are symmetrically arranged on both sides of the inner wall of the second shell, each set of squeezing plate bodies is provided with an upper gravity plate at the upper end, and a metal filter plate is provided at the lower end of the squeezing plate body, and a fermentation filtration system is provided on one side of the second shell, the fermentation filtration system is composed of a liquid filtration structure and a gas filtration structure. The advantages are as follows: The present invention is structurally equipped with a squeezing system and a liquid filtration structure. The squeezing system separates most of the liquid in the manure through squeezing. The liquid enters the fermentation filtration system for filtration and fermentation, while the remaining livestock and poultry manure is mixed with wheat straw and other materials for composting. During the composting process, most pathogenic microorganisms and parasite eggs can be killed, and odor can be removed. At the same time, the probability of manure leakage is reduced. Furthermore, the fertilizer efficiency is greatly improved after composting, which can be used for organic agricultural production. After centralized composting, it can also be transported to other places for use.

[0003] Among the patents or existing technologies mentioned above, one of the mainstream methods for large-scale treatment of livestock and poultry manure is composting in a factory. During the fermentation process, the compost needs to be turned over. Users first use shovels or rakes to stir and aerate the compost regularly. After it is fully decomposed, the loading equipment is used for removal. Existing fermentation composting devices usually have a single function. The turning operation and the discharge operation after fermentation need to be completed by different mechanical equipment. This not only increases the investment in equipment and labor costs, but also leads to low operating efficiency due to multiple transfers and is prone to secondary pollution. Summary of the Invention

[0004] The problem this invention aims to solve is that existing technologies require different equipment for compost turning and discharging, resulting in cumbersome procedures and high costs.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a livestock and poultry manure treatment composting and fermentation device, comprising:

[0006] Fixed structure, fixedly connected to the top of the factory building;

[0007] The drive structure is located below the fixed structure and is fixedly connected to the fixed structure.

[0008] The handle, fixedly connected to the drive structure, is used to control the movement of the device.

[0009] The turning structure, located below the drive structure, includes: shovels, rollers, sleeves, and a switching structure. The rollers are horizontally positioned, and multiple coaxial sleeves are evenly arranged at both ends of the rollers. The rollers pass through the center of each sleeve, and multiple shovels are arranged in a ring on the side wall of each sleeve. The shovels are used to turn the poultry and livestock manure during the fermentation period. The switching structure is located on one side of the shovels and can be combined with the shovels to form a bucket, which is used to throw the composted manure onto the conveyor belt.

[0010] The water supply structure, located on both sides of the drive structure, can control whether water flows out from the end of the blade.

[0011] Furthermore, the fixed structure consists of a hanger and a parallel frame. The parallel frame is parallel to the long axis of the factory building. Both ends of the parallel frame are fixed to the walls of the factory building. A vertical hanger is connected below the parallel frame. The hanger and the parallel frame are slidably connected. The bottom end of the hanger is fixedly connected to the drive structure.

[0012] Furthermore, the drive structure includes a motor and a gearbox. The motor is horizontally positioned, and its output shaft is connected to the gearbox. The gearbox contains a worm gear and a worm. The worm gear is passed through the center by the motor's output shaft. Below the worm gear, there is a meshing worm. Pulleys are located on both sides of the worm. A roller shaft passes vertically through the bottom of the gearbox. Driven wheels are attached to both ends of the gearbox. The driven wheels are coaxially fixed with the roller shaft, and the roller shaft passes through the center of the driven wheels. The driven wheels are connected to the pulleys by a belt.

[0013] Furthermore, the switching structure includes: a sub-plate and a support cloth. Both the sub-plate and the blade are trapezoidal. The end of the sub-plate is close to the end of the blade. The end of the sub-plate is an arc end and is hinged to the blade. The sub-plate can rotate around the junction with the blade. The two sides of the sub-plate are connected to the two sides of the blade through the support cloth. The outer side of the support cloth has a pre-set indentation. When the sub-plate is unfolded, the blade, the sub-plate and the support cloth together form a bucket. When the sub-plate is closed, the blade performs a turning operation on the compost.

[0014] Furthermore, a vertical guide bar and a slider are provided on the side of the blade near the sub-plate. The slider can slide on the guide bar. When the slider slides to the bottom of the guide bar at the junction of the blade and the sub-plate, it pushes the sub-plate to open.

[0015] Furthermore, the guide bar has multiple uniformly recessed fixing holes arranged in a linear array at one end near the sub-plate. An elastic element is provided on the side of the slider facing the fixing hole. The elastic element fits into the fixing hole, so that when the slider slides, the slider is fixed when the elastic element engages with the fixing hole.

[0016] Furthermore, the elastic element includes an end, a spring, and a base. The base is embedded in the slider and has a groove running through its own long axis. A coaxial spring is installed inside the groove. The top of the base is provided with an end, which is slidably connected to the base. The end is hemispherical and located outside the slider, so that when the slider slides on the guide bar, the spring is compressed and the end slides into the base. When the slider slides to the fixing hole, the spring is extended, so that the end engages with the fixing hole.

[0017] Furthermore, the bottom end of the slider is provided with a recessed snap-fit ​​groove, the size of which matches the end of the sub-plate, so that when the sub-plate is closed, the end of the sub-plate is located in the snap-fit ​​groove, thus fixing the sub-plate.

[0018] Furthermore, water tanks are provided on both sides of the gearbox, and the water tanks are fixedly connected to the gearbox. One end of the water tank is provided with a water outlet. The roller shaft is hollow, and the water outlet is connected to a water pipe. Bearings are fixedly connected to the center of both ends of the roller shaft. The water pipe passes through the bearings and is directly connected to the cavity of the roller shaft. The inside of the sleeve is provided with a water passage cavity. One end of the water passage cavity is connected to the internal cavity of the roller shaft, and the other end of the water passage cavity is connected to the top of the shovel. The inside of the shovel is provided with a hollow water outlet cavity. One end of the water outlet cavity is connected to the water passage cavity, and the other end of the water outlet cavity is located at the end of the shovel, so that the water can finally flow out from the end of the shovel.

[0019] Furthermore, the water tank is equipped with a sliding plate inside, which is close to the water outlet. A through-hole is provided on the sliding plate, which matches the water outlet. Both ends of the sliding plate pass through the water tank and extend out of the water tank. A first limiting plate and a second limiting plate are respectively provided on both sides of the sliding plate near the two ends. When the water outlet and the through-hole are connected, that is, the water tank can discharge water, the first limiting plate is in contact with the water tank, and the second limiting plate is away from the water tank. When the water outlet and the through-hole are not connected, that is, the water tank does not discharge water, the first limiting plate is away from the water tank, and the second limiting plate is in contact with the water tank.

[0020] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0021] (1) This invention integrates the functions of turning and discharging, which improves the utilization rate of the equipment and reduces the cost. By setting a sleeve with a ring array of shovels on the roller shaft and adding a switching structure consisting of a secondary plate, support cloth, slider and guide strip on one side of the shovel, the operator can easily open and close the secondary plate by manually operating the position of the slider on the guide strip. When turning is required, the secondary plate is closed and the device is used as a conventional turning machine. The shovel can effectively break up and turn the material. When fermentation is completed and discharge is required, the slider is manually slid to push the secondary plate to open and form a bucket together with the shovel and support cloth, so as to shovel up the decomposed fertilizer and throw it onto the conveyor belt to complete the loading. The process that originally required two machines is integrated into one machine. The user can directly hold the handle to operate the equipment and avoid directly using shovels or rakes to turn or transport, which greatly reduces the equipment cost and labor cost and realizes the integrated process operation from fermentation to discharge.

[0022] (2) This invention achieves precise water addition during composting fermentation through internal water channel design and manual control of water flow by sliding plate, effectively improving fermentation quality. The water tank is set on both sides of the drive structure. Water flows through water pipe into the hollow roller shaft, then through the water passage cavity in the sleeve, and finally into the hollow water outlet cavity inside the shovel and flows out from its end. The operator can intuitively control the flow of water by manually pushing the sliding plate to align or misalign the water passage with the water outlet. The method of water outlet from inside the turning component overcomes the disadvantage of traditional external spraying which easily causes the surface to be too wet and the inside to be dry, thus forming a water dead zone. It ensures that water can directly and evenly penetrate into the deep layer of the material with the turning action of the shovel, significantly improving the uniformity and composting quality of the compost.

[0039] Handle 2 is fixedly connected to drive structure 3 and is used to control the movement of the device.

[0040] The turning structure 5 is located below the drive structure 3 and includes: a shovel 53, a roller 51, a sleeve 52 and a switching structure 6. The roller 51 is horizontally arranged, and multiple coaxial sleeves 52 are evenly arranged at both ends of the roller 51. The center of each sleeve 52 is passed through by the roller 51. Multiple shovels 53 are arranged in a ring on the side wall of each sleeve 52. The shovels 53 are used to turn the poultry and livestock manure during the fermentation period. The switching structure 6 is located on one side of the shovel 53. The switching structure 6 can be combined with the shovel 53 to form a bucket, which is used to throw the composted manure onto the conveyor belt.

[0041] The water supply structure 4 is located on both sides of the drive structure 3 and can control whether water flows out from the end of the blade 53.

[0042] The fixed structure 1 consists of a hanger 11 and a parallel frame 12. The parallel frame 12 is parallel to the long axis of the factory building. Both ends of the parallel frame 12 are fixed to the walls of the factory building. A vertical hanger 11 is connected to the bottom of the parallel frame 12. The hanger 11 and the parallel frame 12 are slidably connected. The bottom end of the hanger 11 is fixedly connected to the drive structure 3.

[0043] The drive structure 3 includes a motor 31 and a reduction gearbox 32. The motor 31 is horizontally positioned, and its output shaft is connected to the reduction gearbox 32. The inside of the reduction gearbox 32 contains a worm gear 321 and a worm 322. The worm gear 321 is passed through the center by the output shaft of the motor 31. The meshing worm 322 is located below the worm gear 321. Pulleys 323 are respectively located on both sides of the worm 322. A roller shaft 51 vertically passes through the bottom end of the reduction gearbox 32. Driven wheels 325 are respectively attached to both ends of the reduction gearbox 32. The driven wheels 325 are coaxially fixed with the roller shaft 51, and the roller shaft 51 passes through the center of the driven wheels 325. The driven wheels 325 and the pulleys 323 are connected by a belt 324.

[0044] The switching structure 6 includes a sub-plate 61 and a support cloth 62. Both the sub-plate 61 and the blade 53 are trapezoidal. The end of the sub-plate 61 is close to the end of the blade 53. The end of the sub-plate 61 is an arc end and is hinged to the blade 53. The sub-plate 61 can rotate around the hinge point with the blade 53. The two sides of the sub-plate 61 are connected to the two sides of the blade 53 through the support cloth 62. The outer side of the support cloth 62 has a pre-set indentation. When the sub-plate 61 is unfolded, the blade 53, the sub-plate 61 and the support cloth 62 together form a bucket. When the sub-plate 61 is closed, the blade 53 performs a turning operation on the compost.

[0045] A vertical guide bar 64 and a slider 63 are provided on the side of the shovel 53 near the sub-plate 61. The slider 63 can slide on the guide bar 64. When the slider 63 slides to the bottom of the guide bar 64 to the junction of the shovel 53 and the sub-plate 61, it pushes the sub-plate 61 to open.

[0046] The guide bar 64 has a linear array of multiple uniformly recessed fixing holes 641 at one end near the sub-plate 61. The slider 63 is provided with an elastic element 632 on the side facing the fixing hole 641. The elastic element 632 fits into the fixing hole 641, so that when the slider 63 slides, the slider 63 is fixed when the elastic element 632 engages with the fixing hole 641.

[0047] The elastic element 632 includes an end 6321, a spring 6322, and a base 6323. The base 6323 is embedded in the slider 63. The base 6323 has a groove that runs through its own long axis. The spring 6322 is coaxially arranged inside the groove. The end 6321 is provided at the top of the base 6323. The end 6321 is slidably connected to the base 6323. The end 6321 is a hemisphere and is located outside the slider 63. When the slider 63 slides on the guide bar 64, the spring 6322 is compressed and the end 6321 slides into the base 6323. When the slider 63 slides to the fixing hole 641, the spring 6322 extends, so that the end 6321 engages with the fixing hole 641.

[0048] The bottom end of the slider 63 is provided with a recessed snap-fit ​​groove 631. The size of the snap-fit ​​groove 631 matches the end of the sub-plate 61, so that when the sub-plate 61 is closed, the end of the sub-plate 61 is located in the snap-fit ​​groove 631, thus fixing the sub-plate 61.

[0049] Water tanks 41 are provided on both sides of the gearbox 32. The water tanks 41 are fixedly connected to the gearbox 32. A water outlet 411 is provided at one end of the water tank 41. The roller 51 is hollow. A water pipe 43 is connected to the water outlet 411. Bearings 44 are fixedly connected at the center of both ends of the roller 51. The water pipe 43 passes through the bearings 44 and is directly connected to the cavity of the roller 51. A water passage cavity 46 is provided inside the sleeve 52. One end of the water passage cavity 46 is connected to the cavity inside the roller 51. The other end of the water passage cavity 46 is connected to the top of the shovel 53. A hollow water outlet cavity 45 is provided inside the shovel 53. One end of the water outlet cavity 45 is connected to the water passage cavity 46. The other end of the water outlet cavity 45 is located at the end of the shovel 53, so that the water can finally flow out from the end of the shovel 53.

[0050] The water tank 41 has a sliding plate 42 inside, which is close to the water outlet 411. The sliding plate 42 has a through water outlet 421 that matches the water outlet 411. Both ends of the sliding plate 42 pass through the water tank 41 and extend out of the water tank 41. A first limiting plate 422 and a second limiting plate 423 are respectively provided on both sides of the sliding plate 42 near the ends. When the water outlet 411 is connected to the through water outlet 421, that is, the water tank 41 can discharge water, so that the first limiting plate 422 is in contact with the water tank 41 and the second limiting plate 423 is away from the water tank 41. When the water outlet 411 is not connected to the through water outlet 421, that is, the water tank 41 does not discharge water, so that the first limiting plate 422 is away from the water tank 41 and the second limiting plate 423 is in contact with the water tank 41.

[0051] The working principle and usage process of this invention are as follows: First, during the composting fermentation stage, the operator holds and pushes the handle 2, which is fixedly connected to the drive structure 3, to move the entire device along the fixed structure 1 at the top of the plant. The motor 31 in the drive structure 3 is started. The power is reduced and changed direction by the worm gear 321 and worm 322 in the reduction gearbox 32. The power is then driven by the belt 324 to rotate the roller shaft 51 and sleeve 52 of the turning structure 5. This causes the shovels 53, which are arranged in a ring on the sleeve 52, to continuously turn the livestock and poultry manure below, achieving aeration and mixing, and promoting fermentation. During this period, if it is necessary to adjust the material humidity, the sliding plate 42 of the water supply structure 4 can be manually pushed so that the water outlet 421 on the sliding plate 42 is aligned with the water outlet 411 of the water tank 41. The water then flows through the water pipe 43 into the hollow roller shaft 51, and then through the water passage 46 in the sleeve 52, and finally flows out evenly from the water outlet 45 at the end of the shovel 53, directly replenishing the deep layer of water to the material during the turning process.

[0052] Secondly, when the composting fermentation is complete and the material needs to be discharged, the operator needs to manually switch the working mode of the turning structure 5. For each shovel 53 component, slide the slider 63 on its side upwards so that it moves to the bottom along the guide bar 64. The snap-fit ​​groove 631 at the bottom of the slider 63 will push the sub-plate 61 hinged to the shovel 53, so that the sub-plate 61 unfolds outward around the hinge. At the same time, the support cloth 62 connected to both sides of the shovel 53 and the sub-plate 61 unfolds accordingly, thus combining with the shovel 53 and the sub-plate 61 to form a bucket. At this time, the elastic element 632 inside the slider 63, under the action of the spring 6322, makes its end 6321 embed into the fixing hole 641 at the bottom of the guide bar 64, locking the position of the slider 63 and ensuring that the sub-plate 61 maintains a stable unfolded state during operation, completing the functional conversion from a turning tool to a loading tool.

[0053] Finally, in the discharge mode, the drive structure 3 starts again, driving the bucket that has completed the transformation to rotate. The rotating bucket can easily scoop up the decomposed compost and use the centrifugal force of rotation to throw the material onto the preset conveyor belt, and then transport it to the transport vehicle for efficient discharge and loading. After all the discharge work is completed, the operator can manually slide the slider 63 upward to the top of the guide bar 64. At this time, the auxiliary plate 61 is reset and closed with manual assistance. The locking groove 631 at the bottom of the slider 63 then locks the end of the auxiliary plate 61, fixing it again. The device returns to the turning state for the next use. At the same time, the sliding plate 42 of the water supply structure 4 is pushed back to the closed position to cut off the water supply.

The scope of protection of the present invention is defined by the claims.
