A spiral extrusion dewatering device for livestock manure treatment

Abstract

This utility model discloses a spiral extrusion dewatering device for livestock and poultry manure treatment, relating to the field of livestock and poultry manure treatment technology. It includes a dewatering machine with a feed inlet fixedly connected to the top. A first mounting frame is fixedly connected to the top of the dewatering machine. This utility model uses a rotating ring to drive the synchronous rotation of a fixed rod, further influencing the movement of a connecting sleeve, a rotating sleeve, and a second moving plate. The rotation of the rotating ring transmits power, causing the rotating sleeve to slide along the fixed rod and continuously changing the contact force between it and the connecting frame. This, in turn, pushes the second moving plate to slide along the surface of the first moving plate. The sliding of the first moving plate triggers the movement of the bottom of the second mounting frame, ensuring that the cleaning rod can effectively clean the feed inlet. The precise motion transmission mechanism of the entire system avoids clogging problems, ensures smooth cleaning, and guarantees that the subsequent extrusion dewatering process is not affected, thus achieving an efficient workflow.

Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry manure treatment technology, and in particular to a spiral extrusion dewatering device for livestock and poultry manure treatment. Background Technology

[0002] Dehydration of livestock and poultry manure is a key step in the resource utilization of livestock and poultry breeding waste. By removing water from the manure, the difficulty of subsequent treatment can be reduced, environmental pollution can be reduced, and resource utilization can be improved.

[0003] For example, CN218372066U discloses a livestock and poultry manure treatment device, which includes casters, a water receiving trough, a mobile frame mechanism, a fixed mechanism, a power mechanism, a feeding mechanism, and a compression discharge mechanism. The fixed mechanism is fixedly installed on the upper end of the mobile frame mechanism, the power mechanism is fixedly installed on one side of the fixed mechanism and away from the compression discharge mechanism, the feeding mechanism is fixedly installed on the fixed mechanism, and the compression discharge mechanism is fixedly installed on the other side of the fixed mechanism.

[0004] However, in existing technologies, blockages can directly prevent feces from entering the processing equipment normally, causing the production line to stop or the feed rate to drop sharply. In continuous processing scenarios, blockages at the feed inlet can force subsequent processes such as dehydration and fermentation to be suspended due to "feed interruption," significantly reducing the processing capacity per unit time. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that blockages directly prevent manure from entering the processing equipment normally, leading to production line stagnation or a sharp reduction in feed volume. Therefore, this invention proposes a screw extrusion dewatering device for livestock and poultry manure processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a screw extrusion dewatering device for treating livestock and poultry manure, including a dewatering machine, with a feed inlet fixedly connected to the top of the dewatering machine, and a first mounting frame fixedly connected to the top of the dewatering machine, a cylinder mounted on the top of the first mounting frame, a movable mechanism connected to the bottom of the cylinder, and a cleaning rod mounted on the bottom of the movable mechanism.

[0007] The mechanism includes a lifting platform, a second mounting frame fixedly connected to the bottom of the lifting platform, a track fixedly connected to the top center of the second mounting frame, a movable rod slidably connected to the inner side of the track, a rotating sleeve fixedly connected to the top of the movable rod, a connecting frame rotatably connected to the top of the rotating sleeve, a second movable plate fixedly connected to the inner sides of both ends of the connecting frame, a first movable plate slidably connected to the top of the second movable plate, the first movable plate slidably connected to the bottom of the second mounting frame, and a central rod rotatably connected to the middle of the second mounting frame.

[0008] Preferably, a limit rod is fixedly connected to the side wall of the lifting plate, and one end of the limit rod is slidably connected to the surface of the first mounting frame.

[0009] Preferably, a drive motor is installed on the side wall of the lifting plate, and a drive wheel is fixedly connected to the output end of the drive motor.

[0010] Preferably, a timing belt is fitted onto the outer surface of the drive wheel, and a rotating ring is fitted onto the inner side of one end of the timing belt.

[0011] Preferably, a fixing rod is fixedly connected to the center of the inner side of the rotating ring, and a connecting sleeve is slidably connected to the surface of the fixing rod.

[0012] Preferably, a central rod is fixedly connected to the bottom of the connecting sleeve, and the bottom of the central rod is rotatably connected to the second mounting bracket.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotating ring drives the fixed rod to rotate synchronously, which further affects the movement state of the connecting sleeve, the rotating sleeve and the second moving plate. The rotation of the rotating ring transmits power, causing the rotating sleeve to slide along the fixed rod and the contact force between it and the connecting frame to change continuously. This pushes the second moving plate to slide along the surface of the first moving plate. The sliding of the first moving plate causes the bottom of the second mounting frame to move, ensuring that the cleaning rod can effectively clean the feed inlet. The precise motion transmission mechanism of the entire system avoids the problem of blockage, ensures that the cleaning work is carried out smoothly, and ensures that the subsequent extrusion and dehydration process is not affected, thus achieving an efficient workflow.

[0015] 2. In this utility model, a drive motor and a drive wheel provide power, which is transmitted to the rotating ring via a synchronous belt, thereby driving the cleaning rod to perform cleaning work. The movement of the cleaning rod is strictly limited by the track to ensure that it moves along a fixed path, avoids deviation, and ensures the accuracy of the cleaning range. The moving rod moves synchronously with the cleaning rod, further improving the cleaning effect and coverage. The cylinder provides a height adjustment function for the cleaning rod to ensure that the cleaning adapts to different height requirements. The lifting plate slides with the first mounting bracket through a limit rod to achieve precise guidance during the lifting process, ensuring that the cleaning rod is stable and highly accurate in height during the lifting process, improving the cleaning effect, and avoiding the occurrence of movement errors or deviations.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a screw extrusion dewatering device for livestock and poultry manure treatment, including a dewatering machine 1. The top of the dewatering machine 1 is fixedly connected to a feed inlet 2, and the top of the dewatering machine 1 is fixedly connected to a first mounting frame 3. A cylinder 4 is mounted on the top of the first mounting frame 3, and a movable mechanism 5 is connected to the bottom of the cylinder 4. A cleaning rod 6 is mounted on the bottom of the movable mechanism 5.

[0024] The movable mechanism 5 includes a lifting plate 51, a second mounting frame 54 fixedly connected to the bottom of the lifting plate 51, a track 55 fixedly connected to the top center of the second mounting frame 54, a moving rod 562 slidably connected to the inner side of the track 55, a rotating sleeve 561 fixedly connected to the top of the moving rod 562, a connecting frame 56 rotatably connected to the top of the rotating sleeve 561, a second moving plate 59 fixedly connected to the inner sides of both ends of the connecting frame 56, a first moving plate 58 slidably connected to the top of the second moving plate 59, the first moving plate 58 slidably connected to the bottom of the second mounting frame 54, and a central rod 573 rotatably connected to the middle of the second mounting frame 54.

[0025] The specific settings and functions of this embodiment will be described in detail below. During the rotation of the rotating ring 57, due to its special design, it not only causes the fixed rod 571 to rotate synchronously, but also further affects the motion state of the connecting sleeve 572. The fixed rod 571 is directly connected to the rotating ring 57, so it maintains the same motion trajectory as the rotating ring 57 during rotation, driving the connecting sleeve 572 to rotate around the central rod 573 as the fulcrum. As the rotating ring 57 continues to rotate, this rotational force will be gradually transmitted to the rotating sleeve 561, thus generating a more complex power transmission process.

[0026] At this time, the rotating sleeve 561 not only rotates relative to the connecting frame 56, but also slides along the surface of the fixed rod 571. This sliding causes the contact force between the rotating sleeve 561 and the connecting frame 56 to change continuously. Due to the continuous force from the rotating sleeve 561, the connecting frame 56 begins to bear and transmit the corresponding force, thereby driving the movement of the second moving plate 59. It is worth noting that since the movement of the rotating ring 57 is essentially circular, the trajectory of the second moving plate 59 exhibits a dynamic change similar to rotation. During this process, the second moving plate 59 will slide along the surface of the first moving plate 58.

[0027] As the second moving plate 59 slides continuously on the first moving plate 58, its movement triggers the movement of the first moving plate 58, which in turn slides at the bottom of the second mounting bracket 54. This series of coordinated movements ensures that the cleaning rod 6 can effectively participate in cleaning the feed inlet 2, thereby avoiding functional obstacles caused by blockage. Through this precise structural design and motion transmission mechanism, the circumferential motion of the rotating ring 57 not only drives the sliding of the second moving plate 59 but also ensures smooth cleaning, avoiding any impact on the subsequent extrusion and dehydration process, thus achieving efficient operation of the entire system.

[0028] Example 2: Figures 2-3 As shown, a limit rod 511 is fixedly connected to the side wall of the lifting plate 51, and one end of the limit rod 511 is slidably connected to the surface of the first mounting frame 3. A drive motor 52 is installed on the side wall of the lifting plate 51, and a drive wheel 521 is fixedly connected to the output end of the drive motor 52. A synchronous belt 53 is sleeved on the outer surface of the drive wheel 521, and a rotating ring 57 is sleeved on the inner side of one end of the synchronous belt 53. A fixing rod 571 is fixedly connected to the center of the inner side of the rotating ring 57, and a connecting sleeve 572 is slidably connected to the surface of the fixing rod 571. A center rod 573 is fixedly connected to the bottom of the connecting sleeve 572, and the bottom of the center rod 573 is rotatably connected to the second mounting frame 54.

[0029] The overall effect of this embodiment is that the drive motor 52 drives the rotation of the system via the drive wheel 521. The drive wheel 521 rotates under the drive of the motor, transmitting mechanical energy to the timing belt 53. The timing belt 53 is a highly efficient power transmission device that transmits rotational power to the rotating ring 57. During continuous rotation, the rotating ring 57 drives the cleaning rod 6 connected to it to perform corresponding movements, thereby carrying out the cleaning work.

[0030] The movement trajectory of the cleaning rod 6 is strictly limited by the track 55. Specifically, the existence of the track 55 ensures that the cleaning rod 6 moves along a fixed path, preventing deviation during movement. The interaction between the cleaning rod 6 and the track 55 ensures the accuracy of the cleaning range. The moving rod 562 is a key component in the cleaning system; as the cleaning rod 6 moves, the moving rod 562 slides within the track 55. Since the movement of the moving rod 562 is synchronized with that of the cleaning rod 6, it means that the movement trajectory of the cleaning rod 6 is consistent with the trajectory of the moving rod 562 within the track 55, further ensuring the integrity and cleaning effect of the cleaning, and improving the coverage of the cleaning range.

[0031] In addition, the cylinder 4 provides height adjustment for the cleaning rod 6. By controlling the cylinder 4, the height of the cleaning rod 6 can be adjusted during the lifting and lowering of the lifting plate 51, ensuring that the cleaning operation can adapt to different height requirements. When the lifting plate 51 moves up and down, the limiting rod 511 slides against the surface of the first mounting bracket 3. The sliding of the limiting rod 511 acts as a guide, preventing displacement deviation during lifting and lowering. This guiding mechanism ensures the stability of the lifting plate 51 and the cleaning rod 6, as well as precise height control.

[0032] The operating principle and usage of this device are as follows: The drive motor 52 transmits force to the drive wheel 521. During rotation, the drive wheel 521 transmits force to the rotating ring 57 via the synchronous belt 53. As the rotating ring 57 rotates, it drives the fixed rod 571 to rotate as well. During this process, the fixed rod 571 not only rotates synchronously but also drives the connecting sleeve 572 to rotate, rotating around the central rod 573. As the rotating ring 57 continues to rotate, it transmits force to the rotating sleeve 561. At this time, the rotating sleeve 561 not only rotates relative to the connecting frame 56 but also slides on the surface of the fixed rod 571. During this process, the connecting frame 56 is subjected to force from the rotating sleeve 561, thus transmitting the force to the second moving plate 59. Because the rotating ring 57 performs circular motion, when it drives the second moving plate 59, it causes it to slide on the surface of the first moving plate 58. Simultaneously, the first moving plate 58 slides at the bottom of the second mounting frame 54, thereby preventing the cleaning rod 6 from becoming clogged when cleaning the feed inlet 2, thus avoiding disruption to the normal extrusion and dehydration process.

[0033] The movement trajectory of the cleaning rod 6 is limited by the track 55. Since the moving rod 562 slides inside the track 55 when it moves, the movement trajectory of the cleaning rod 6 is the same as the movement trajectory of the moving rod 562 inside the track 55, thereby expanding the cleaning range.

[0034] The height of the cleaning rod 6 can be adjusted by using the cylinder 4. During the lifting process of the lifting plate 51, the limit rod 511 will slide on the surface of the first mounting bracket 3, thereby playing a guiding role.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
