Description

Technical Field

[0001] The invention relates to the technical field of livestock excrement recovery, in particular to a livestock excrement recovery device. Background Art

[0002] As an important part of the material cycle between humans and the natural environment, animal husbandry plays an indispensable role. In the process of livestock breeding, the large amount of manure produced by animals in the enclosure area is a key point in management. In order to protect the enclosure ground from erosion by manure and provide a dry and comfortable environment for livestock, a thick layer of straw is usually laid. However, when it is necessary to recycle these manure, there are considerable challenges. Although livestock manure combined with agricultural waste such as straw can be converted into high-quality organic fertilizer, it is not suitable to use it directly because it is mixed with too much straw. Therefore, it is necessary to effectively separate and treat the manure mixed with a large amount of straw first. The separated manure contains less straw impurities and can become an efficient organic fertilizer after the composting and fermentation process; and the separated straw can be processed by drying and other methods and then used again for laying in the enclosure area.

[0003] However, in practice, efficient separation of straw contaminated with feces mainly relies on water washing. Although this method can effectively remove feces, it is easy to cause straw accumulation during the filtration process, increasing the burden on the equipment and even causing equipment damage. In addition, the large amount of water used will also lead to water resource waste and subsequent sewage treatment problems, causing additional pressure on the environment. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1-2 , which is the first embodiment of the present invention, and provides a livestock manure recovery device, which includes a feeding unit 1, including a feeding port 11, a support frame 12 arranged at the bottom of the feeding port 11, a feeding pipe 13 arranged at one side of the support frame 12, and a flexible warehouse channel 14 arranged at the bottom of the feeding pipe 13; The processing unit 2 includes a mixing tank 21 disposed at the bottom of the flexible warehouse channel 14, a separation component 22 disposed through the inside of the mixing tank 21, an anti-overload component 23 disposed outside the mixing tank 21, and a driving component 24 disposed at the bottom of the mixing tank 21; The retracting unit 3 includes a support frame 31 mounted on the outside of the mixing tank 21 and a sliding assembly 32 disposed on one side of the support frame 31 .

[0030] Furthermore, a spiral rod 131 is disposed inside the feed pipe 13, and an output end 132 is fixedly disposed on the top of the spiral rod 131; The stirring tank 21 includes a U-shaped inner cavity 211 disposed inside the stirring tank 21 , a discharge pipe 212 disposed at the bottom of the U-shaped inner cavity 211 , and a valve port 213 disposed inside the discharge pipe 212 .

[0031] Furthermore, the separation assembly 22 includes a transmission rod 221 hingedly disposed at the center of the U-shaped inner cavity 211, a collecting member 222 fixedly clamped to one side of the transmission rod 221, and a transmission shaft 223 fixedly disposed at the end of the transmission rod 221; The driving assembly 24 includes a protective cover 241 disposed at the bottom of the mixing tank 21, a motor 242 disposed inside the protective cover 241, and a pulley 243 disposed on one side of the motor 242; The transmission shaft 223 is connected to the pulley 243 through a belt. It should be noted that the feed port 11 is wide and faces upward, so that the staff can shovel the straw with feces into it. A support frame 12 is installed at the bottom of the feed port 11 to facilitate the feed port 11 to be erected. A spiral rod 131 and an output end 132 fixed at the top are arranged inside the feed pipe 13, and the spiral rod 131 is used to push the mixture of feces and straw upward along the feed pipe 13 until it enters the flexible warehouse 14 in the processing unit 2.

[0032] Preferably, the feeding unit 1 is of the prior art, and mainly serves to transport the mixture of excrement and rice straw. The feeding unit 1 may also be provided with a conveyor belt for transportation.

[0033] Preferably, the processing unit 2 is mainly composed of a stirring tank 21, a separation component 22, an anti-overload component 23 and a driving component 24. The stirring tank 21 is designed with a U-shaped inner cavity 211, which is U-shaped to facilitate the filtering of feces. A discharge pipe 212 and a valve port 213 are provided at the bottom to control the discharge of materials; the separation component 22 includes a transmission rod 221 hinged at the center of the U-shaped inner cavity 211, a collecting piece 222 fixed on one side thereof, and a transmission shaft 223 located at the end of the transmission rod 221, and the collecting piece 222 is used to capture straw during rotation; the driving component 24 is composed of a protective cover 241, a motor 242 and a pulley 243, and the motor 242 drives the transmission shaft 223 to rotate through the pulley 243 and the belt, thereby driving the entire separation component 22 to operate. The retraction unit 3 includes a support frame 31 mounted on the outside of the mixing tank 21 and a sliding assembly 32 arranged on one side thereof. The sliding assembly 32 enables the support frame 31 to move along a predetermined track, making it convenient for operators to approach the processing unit 2 for maintenance or cleaning operations.

[0034] Preferably, corrosion-resistant materials can be selected to manufacture all parts that come into contact with feces, and the design of the collecting member 222 can adopt a replaceable structure to facilitate regular replacement or cleaning to maintain good working condition.

[0035] During operation, the mixture of feces and straw enters the feeding pipe 13 through the feeding port 11, and is pushed into the U-shaped inner cavity 211 inside the mixing tank 21 under the action of the spiral rod 131, and a water pipe is connected from the other side of the mixing tank 21 to dilute the feces and straw mixture in the mixing tank 21. After starting the motor 242, the transmission shaft 223 is rotated through the transmission mechanism of the pulley 243 and the belt, thereby driving the transmission rod 221 and the collecting member 222 fixed thereon to rotate. The collecting member 222 can effectively capture the straw in the mixture during its rotation, and the feces settle to the bottom of the U-shaped inner cavity 211 due to gravity. After the separation is completed, the valve port 213 is opened to discharge the separated feces water through the discharge pipe 212, and the straw accumulated on the collecting member 222 can be removed manually or mechanically, and can be reused for laying in the enclosure site after drying.

[0036] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a transmission rod 221 including a screw rod 2211, and a sleeve rod 2212 movably sleeved on the outside of the screw rod 2211; A hole 22121 is defined inside the sleeve rod 2212 , and the screw rod 2211 is movably sleeved inside the hole 22121 .

[0037] Furthermore, the sleeve rod 2212 also includes two groups of connecting columns 22122 disposed at both ends thereof, a threaded ring 22123 disposed at the end of one group of connecting columns 22122, and a clamping ring 22124 disposed at the end of the other group of connecting columns 22122; The threaded ring 22123 is threadedly connected to the transmission rod 221 .

[0038] It should be noted that if Figure 2 and Figure 3 As shown, the transmission rod 221 is hingedly mounted at the center of the U-shaped inner cavity 211. The transmission rod 221 is composed of an embedded screw rod 2211 and a sleeve rod 2212 sleeved on the outside of the screw rod 2211. The screw rod 2211 is connected to the transmission shaft 223 as a direct transmission member through a flange connection. The transmission shaft 223 can directly drive the screw rod 2211 to rotate under the drive of the pulley 243. The high efficiency and stability of power transmission are ensured.

[0039] Preferably, the sleeve rod 2212 is slidably sleeved on the outside of the screw rod 2211, and two groups of connecting columns 22122 with larger outer diameters are fixedly extended at both ends of the rod body. A threaded ring 22123 is fixedly extended at the end of one group of connecting columns 22122, and the threaded ring 22123 matches the threaded portion on the outside of the screw rod 2211, and a reliable connection between the sleeve rod 2212 and the screw rod 2211 is achieved by threaded connection. A clamping ring 22124 is fixed at the end of the other group of connecting columns 22122, and the clamping ring 22124 can slide and hinge the sleeve rod 2212 on the rear end of the mixing tank 21, ensuring the stability of the rotation of the entire transmission rod 221.

[0040] Preferably, when the motor 242 is started and the transmission shaft 223 is driven to rotate through the pulley 243 and the belt, the rotational motion of the transmission shaft 223 is directly transmitted to the screw rod 2211, so that it rotates synchronously. Since the sleeve rod 2212 is not limited in the radial direction, when the screw rod 2211 rotates, the sleeve rod 2212 will also rotate together. This ensures the coordinated movement of the transmission rod 221 as a whole, avoiding the problem of unbalanced movement caused by uneven local force.

[0041] Preferably, a hole 22121 is provided inside the sleeve rod 2212, and the diameter of the hole 22121 is slightly larger than the diameter of the screw rod 2211, so that the sleeve rod 2212 can slide freely on the screw rod 2211 without generating too large a gap. A plurality of sets of snap rings are arranged in a linear array inside the hole 22121, and these snap rings are evenly distributed over the length of the entire hole 22121, so as to ensure the stability of the sleeve rod 2212 when rotating with the screw rod 2211, and prevent it from shaking or deflecting during the rotation process.

[0042] Furthermore, the collecting member 222 includes a rod frame 2221 fixedly arranged on the outside of the connecting column 22122, a filter screen 2222 fixedly arranged on the inside of the rod frame 2221, a rake tooth 2223 fixedly arranged on one side of the rod frame 2221, and a contact block 2224 fixedly arranged on the side of the rod frame 2221.

[0043] It should be noted that if Figure 4 As shown, the rod frame 2221 is a U-shaped structure, and its two ends are firmly plugged into the connecting columns 22122 at both ends by fixed card plugging, ensuring that the rod frame 2221 can rotate with the sleeve rod 2212. It can ensure a stable connection between the rod frame 2221 and the sleeve rod 2212, and facilitate installation and disassembly, maintenance and replacement.

[0044] Preferably, a set of filter screens 2222 are fixedly connected to the inner side of the rod frame 2221. The filter screens 2222 have a larger filter hole diameter, which can effectively filter out larger straws, while smaller feces particles can pass through the filter screens 2222 and fall into the bottom of the U-shaped inner cavity 211. The design of the filter screens 2222 ensures the effective separation of straw and feces, and improves the separation efficiency.

[0045] Preferably, a plurality of groups of rake teeth 2223 are arranged in a linear array on the end surface of the side of the U-shaped rod frame 2221. The rake teeth 2223 are prior art, and their design can effectively gather the straw onto the filter screen 2222 during the rotation process, further enhancing the straw capture effect. The arrangement and density of the rake teeth 2223 are optimized to ensure that the straw can be evenly captured and gathered during the rotation process, and to avoid uneven distribution of the straw on the filter screen 2222. A group of mounting grooves with the same length as the side of the rod frame 2221 are provided on the side wall of the rod frame 2221, and a group of contact blocks 2224 are fixedly connected in the mounting groove. The design of the contact block 2224 allows it to contact the anti-overload component, so as to determine whether the rod frame 2221 can continue to rotate with the screw 2211. When too much straw accumulates on the collecting member 222, resulting in an increase in the rotation resistance, the contact block 2224 will contact the anti-overload component, triggering the anti-overload protection mechanism, stopping the rotation movement, and preventing the equipment from being overloaded and damaged. This design not only improves the safety of the equipment, but also extends its service life.

[0046] Furthermore, a rectangular groove M is provided on the side wall of the mixing tank 21; The overload protection assembly 23 includes a fixing frame 231 extending through the rectangular slot 24, a stopper 232 slidably disposed inside the fixing frame 231, tension springs 233 disposed on both sides of the stopper 232, and a box body 234 disposed outside the stopper 232.

[0047] Furthermore, the stopper 232 includes a first contact surface 2321 formed on an end surface thereof; The contact block 2224 includes a second contact surface 22241 disposed on an end surface thereof; The first contact surface 2321 and the second contact surface 22241 are slidably matched.

[0048] Furthermore, the stopper 232 also includes a fixed end 2322 disposed at the rear end thereof; The fixed end 2322 is slidably disposed inside the rectangular groove M; One end of the tension spring 233 is hung on the end surface of the fixed end 2322 , and the other end is hung on the side wall of the stirring tank 21 .

[0049] It should be noted that if Figure 5 and 6 As shown, the anti-overload component 23 is installed on the straight side wall of the mixing tank 21. When the contact block 2224 follows the sleeve rod 2212 to rotate clockwise, it will slide and rub on the bottom of the anti-overload component 23, thereby squeezing the anti-overload component 23. Among them, a group of rectangular grooves M are opened on the straight side wall of the mixing tank 21, and the anti-overload component 23 is in contact with the contact block 2224 through the rectangular grooves M. A rectangular fixing frame 231 is embedded in the rectangular groove M with threads, and a smaller rectangular groove is opened inside the fixing frame 231, and a stopper 232 can be slidably connected in the rectangular groove, and the front end of the stopper 232 is a first contact surface 2321. Similarly, the side of the contact block 2224 that contacts the stopper 232 is a second contact surface 22241. When the contact block 2224 slides and contacts the bottom of the stopper 232 , the force required for the first contact surface 2321 to retreat after the second contact surface 22241 contacts the first contact surface 2321 is used to determine whether too much straw debris is accumulated in the separation component 22 .

[0050] Preferably, the front end of the stopper 232 is a first contact surface 2321, and the rear end is a fixed end 2322. The fixed end 2322 is composed of two groups of L-shaped blocks symmetrically arranged at the rear end of the first contact surface 2321, and a group of tension springs 233 are connected to the side of the fixed end 2322 opposite to the straight side wall of the mixing tank 21, one end of the tension spring 233 is connected to the fixed end 2322, and the other end is connected to the side of the mixing tank 21. When the second contact surface 22241 contacts the first contact surface 2321, the tension spring 233 will be stretched during the retreat of the first contact surface 2321. A group of boxes 234 are fixedly connected to the outside of the two groups of tension springs 233, and the box 234 provides protection for the anti-overload component 23.

[0051] Preferably, when the second contact surface 22241 contacts the first contact surface 2321, the first contact surface 2321 will retreat. The second contact surface 22241 and the first contact surface 2321 can be inclined surfaces, which can slide relative to each other after contacting, so as to retreat; or they can be curved surfaces.

[0052] Furthermore, a retraction window N is also provided at the rear end of the mixing tank 21; The sliding assembly 32 includes a plurality of pulley plates 321 mounted on the support frame 31 and a rod seat 322 disposed on the pulley plates 321 .

[0053] It should be noted that if Figure 7As shown, a set of retraction windows N is provided at the rear end of the mixing tank 21. When the separation assembly 22 is intercepted by a lot of straw debris during operation, causing the sleeve rod 2212 to be unable to rotate and retract normally following the screw rod 2211, the sleeve rod 2212 carrying the straw debris can be withdrawn through the retraction window N, thereby avoiding the device from being stuck or damaged. The sliding assembly 32 includes a plurality of pulley plates 321 mounted on the carrier 31, and a rod seat 322 arranged on the pulley plate 321. The pulley plate 321 is slidably connected to the carrier 31 through a slide rail and can slide freely on the carrier 31. A rod seat 322 is fixedly connected to the end surface of each set of pulley plates 321, and the rod seat 322 is used to support and fix the sleeve rod 2212 withdrawn from the retraction window N. When the sleeve rod 2212 withdraws through the retraction window N, the pulley plate 321 can slide along the slide rail, thereby setting up the sleeve rod 2212, maintaining its force balance, and facilitating subsequent cleaning and maintenance work.

[0054] When in use, the mixture of feces and straw enters the feeding pipe 13 through the feeding port 11 with a wide mouth facing upward. The spiral rod 131 inside the feeding pipe 13 rotates under the drive of the motor, pushing the mixture upward along the feeding pipe 13 until it enters the flexible warehouse 14 in the processing unit 2. After the mixture enters the U-shaped inner cavity 211 inside the mixing tank 21, it is diluted through the water pipe connected to one side of the mixing tank 21, so that the mixture of feces and straw is easier to separate. The motor 242 is started, and the transmission shaft 223 is driven to rotate through the pulley 243 and the belt, thereby driving the screw 2211 to rotate.

[0055] During the clockwise rotation of the screw rod 221, the sleeve rod 2212 will be in two states; when the sleeve rod 2212 has no radial limiting effect or the effect is small, such as when the sleeve rod 2212 drives the filter screen 2222 and the rake teeth 2223 to collect straw debris, there are few debris, and the screw rod 221 drives the contact block 2224 on the side of the rod frame 2221 to contact the block 232 of the anti-overload component 23, and its rotation resistance is small, and the second contact surface 22241 can be smoothly squeezed and dislocated with the first contact surface 2321, and the block 232 is squeezed back, and the contact block 2224 cannot be intercepted, and the sleeve rod 2212 rotates clockwise normally to collect straw debris. The rake teeth 2223 gather the straw onto the filter screen 2222, and the smaller feces particles pass through the filter screen 2222 and fall into the bottom of the U-shaped inner cavity 211.

[0056] Secondly, when too much straw accumulates on the collecting piece 222, resulting in increased rotational resistance, the contact block 2224 on the side of the rod frame 2221 will contact the block 232 of the anti-overload component 23, and the second contact surface 22241 of the contact block 2224 cannot squeeze the block 232 and stretch the tension spring 233, resulting in the inability to smoothly slide and misalign with the first contact surface 2321 of the block 232, resulting in the sleeve rod 2212 being unable to normally follow the screw rod 2211 to rotate clockwise, turning it into a linear sliding component to allow it to retreat, then the sleeve rod 2212 retreats out of the retreat window N under the blocking action of the block 232, and retreats the collecting piece 222 carrying straw debris.

[0057] When the sleeve rod 2212 exits through the retraction window N, the pulley plate 321 can slide along the slide rail to set up the sleeve rod 2212, keep its force balance, and facilitate the operator to perform cleaning and maintenance work. After the separation is completed, the valve port 213 at the bottom of the mixing tank 21 is opened to discharge the separated manure water through the discharge pipe 212. The straw on the collecting piece 222 can be removed manually or mechanically, and after drying, it can be reused for laying in the enclosure site to achieve the recycling of resources.

[0058] When installing after cleaning, the motor 242 drives the reverse screw rod 221 and limits the rotation of the sleeve rod 2212. When the clamping ring 22124 is successfully clamped on the rear end of the mixing tank 21, the installation is completed.

[0059] In summary, in the device, the overload protection component 23 interacts with the contact block 2224 and the stopper 232. When the overload protection component 23 triggers the protection mechanism, the sleeve rod 2212 cannot rotate clockwise with the screw rod 2211 normally, but becomes a linear sliding component, so that it retreats and exits the mixing tank 21 through the retreat window N. It is convenient for operators to carry out cleaning and maintenance work. It makes the maintenance and cleaning of the equipment more convenient and quick, reducing downtime and maintenance costs. It effectively prevents damage to the equipment due to overload, prolongs the service life of the equipment, and ensures safe operation.

[0060] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
