Description

Technical Field

[0001] This utility model relates to the field of earthworm farming technology, specifically to a soil screening device for earthworm farming. Background Technology

[0002] Earthworms are one of the important Chinese medicinal materials, with the effects of clearing heat and calming the nerves, promoting blood circulation, relieving asthma, and promoting diuresis. They are the raw materials for many Chinese medicines, Western medicines, and veterinary drugs. When raising them, it is necessary to screen the soil to ensure the environment for earthworm production.

[0003] Currently, manual sieving using sieves is inefficient and labor-intensive. While some vibrating screens offer faster sieving speeds, they can only perform single-layer sieving and cannot finely sieve soil in layers, failing to meet the soil fineness requirements of earthworms at different growth stages. Therefore, a soil sieving device for earthworm farming needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a soil screening device for earthworm farming, in order to solve the problems mentioned in the background art, which are currently low-efficiency and labor-intensive due to manual screening using sieves. Some vibrating screens have a fast screening speed, but can only perform single-layer screening and cannot perform layered fine screening of the soil, thus failing to meet the soil fineness requirements of earthworms at different growth stages.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil screening device for earthworm farming, comprising a bottom box, characterized in that: the bottom inner side of the bottom box is rotatably connected to the bottom of a base plate via a support shaft; a hydraulic rod is fixedly installed at one end of the bottom inner side of the bottom box; a movable plate is fixedly installed at the end of the hydraulic rod; a support rod is rotatably installed on the movable plate; the top end of the support rod is rotatably connected to one end of the bottom surface of the base plate; a spring telescopic rod is fixedly installed on the top surface of the base plate; the top end of the spring telescopic rod is fixedly connected to the outer edge of the bottom surface of a receiving plate; a resistance-reducing roller is rotatably installed in the middle of the bottom surface of the receiving plate; a servo motor is fixedly installed at one end of the top surface of the base plate; an eccentric wheel is installed on the output shaft of the servo motor; the top end of the eccentric wheel is in contact with the bottom end of the resistance-reducing roller; a positioning rod is fixedly installed on the bottom inner side of the receiving plate; a screening cylinder is fixedly installed at the top end of the positioning rod; a sieve frame is installed inside the screening cylinder; a locking bolt is installed on the side wall of the screening cylinder; the locking bolt is connected to the sieve frame; and a screen is fixedly installed on the bottom inner side of the sieve frame.

[0007] Preferably, the support rods are symmetrically distributed about the center of the movable plate, and the support rods are inclined.

[0008] Preferably, the spring telescopic rods are symmetrically distributed about the center of the receiving plate, and the distance between adjacent spring telescopic rods is greater than the radius of the receiving plate.

[0012] 1. The hydraulic rod extends and retracts to drive the movable plate to move horizontally back and forth slightly. The movable plate pushes and pulls the support rod, which drives the base plate, receiving plate and screening cylinder to rotate and swing slightly forward and backward around the support shaft. In conjunction with the servo motor driving the eccentric wheel to rotate stably in one direction, the eccentric wheel intermittently squeezes the drag-reducing roller, causing the receiving plate to vibrate up and down under the support of the spring telescopic rod, thereby improving screening efficiency.

[0013] 2. The screen frame is positioned by locking bolts. Multiple screen frames and screens can perform stratified fine sieving of soil. The screen frames can be easily disassembled, which facilitates the collection of soil of different fineness in different screen frames and improves the overall applicability of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a soil screening device for earthworm farming, comprising a base box 1, a support shaft 2, a base plate 3, a hydraulic rod 4, a movable plate 5, a support rod 6, a spring telescopic rod 7, a receiving plate 8, a resistance-reducing roller 9, a servo motor 10, an eccentric wheel 11, a positioning rod 12, a screening cylinder 13, a screen frame 14, a locking bolt 15, and a screen 16. The bottom inner side of the base box 1 is rotatably connected to the bottom of the base plate 3 via the support shaft 2. A hydraulic rod 4 is fixedly installed at one end of the bottom inner side of the base box 1, and a movable plate 5 is fixedly installed at the end of the hydraulic rod 4. A support rod 6 is rotatably installed on the movable plate 5, and the top end of the support rod 6 is rotatably connected to one end of the bottom surface of the base plate 3. A spring telescopic rod 7 is fixed on the top surface of the substrate 3. The top end of the spring telescopic rod 7 is connected and fixed to the outer bottom edge of the receiving plate 8. A drag-reducing roller 9 is rotatably installed in the middle of the bottom surface of the receiving plate 8. A servo motor 10 is fixed at one end of the top surface of the substrate 3. An eccentric wheel 11 is installed on the output shaft of the servo motor 10. The top end of the eccentric wheel 11 is in contact with the bottom end of the drag-reducing roller 9. A positioning rod 12 is fixedly installed on the bottom inner side of the receiving plate 8. A screening cylinder 13 is fixed at the top end of the positioning rod 12. A screen frame 14 is installed inside the screening cylinder 13. A locking bolt 15 is installed on the side wall of the screening cylinder 13. The locking bolt 15 is connected to the screen frame 14. A screen mesh 16 is fixedly installed on the bottom inner side of the screen frame 14.

[0021] In this example, the hydraulic rods 4 are symmetrically distributed about the center of the movable plate 5. The front view of the movable plate 5 is "L" shaped. The bottom surface of the movable plate 5 is in contact with the inner bottom surface of the base box 1. The above structural design enables the hydraulic rods 4 to push and pull the movable plate 5 to move stably in a straight line along the inner bottom surface of the base box 1.

[0022] The support rods 6 are symmetrically distributed about the center of the movable plate 5. The support rods 6 are inclined. The above structural design allows the movable plate 5 to rotate by pushing and pulling the support rods 6 during linear displacement, thereby driving the base plate 3 to rotate stably and slightly.

[0023] The spring telescopic rods 7 are symmetrically distributed about the center of the receiving plate 8, and the distance between adjacent spring telescopic rods 7 is greater than the radius of the receiving plate 8. The above structural design enables the spring telescopic rods 7 to provide stable support for the receiving plate 8, ensuring the stability of the receiving plate 8 during movement.

[0024] The drag-reducing rollers 9 are evenly spaced, and the side curved surfaces of the drag-reducing rollers 9 and the side curved surfaces of the eccentric wheels 11 are both set as mirror surfaces. The eccentric wheels 11 are evenly spaced. The above structural design makes the resistance small when the eccentric wheels 11 come into contact with the drag-reducing rollers 9, and can stably and smoothly squeeze and push the drag-reducing rollers 9.

[0025] The sieve frames 14 are evenly spaced, and the mesh diameter of the sieve screens 16 inside the sieve frames 14 decreases from top to bottom. The above structural design can screen and retain soil of different fineness in layers, reducing the possibility of clogging.

[0026] Working principle: When using this device, the hydraulic rod 4 and the servo motor 10 are started simultaneously. The hydraulic rod 4 first extends and then retracts. The hydraulic rod 4 first pushes the movable plate 5 and then pulls the movable plate 5, causing the movable plate 5 to perform horizontal reciprocating motion. The movable plate 5 moves synchronously with the support rod 6. The support rod 6 rotates first to push the base plate 3 to rotate counterclockwise around the support shaft 2, and then pulls the base plate 3 to rotate clockwise around the support shaft 2 to reset. This process is repeated, and the base plate 3, along with the receiving plate 8 and the screening cylinder 13, rotates and swings slightly.

[0027] At the same time, the servo motor 10 drives the eccentric wheel 11 to rotate stably in one direction through the output shaft. The eccentric wheel 11 uses its eccentric characteristics to first squeeze the drag-reducing roller 9 and the receiving plate 8 upward, and stretch the spring telescopic rod 7. Then the eccentric wheel 11 stops squeezing the drag-reducing roller 9, and the receiving plate 8 moves down and resets under the action of gravity and the elastic force of the spring telescopic rod 7. This process is repeated, and the receiving plate 8 carries the screening cylinder 13 to vibrate up and down.

[0028] Soil is poured into the screening cylinder 13 from the top. The screening cylinder 13 passes through the screens 16 in different screen frames 14. The uppermost screen 16 retains larger soil particles. The soil particles retained on the screen 16 decrease sequentially downwards, with the finest soil particles falling into the receiving tray 8.

[0029] After screening, the hydraulic rod 4 and servo motor 10 stop working, the finest soil in the receiving plate 8 is collected, the locking bolt 15 is rotated to disengage from the screen frame 14, the screen frame 14 and the soil trapped on the screen mesh 16 inside it are taken out, the soil is poured out, the screen frame 14 is reinstalled and reset, and the whole device can work again. This is the working principle of the soil screening device for earthworm breeding.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
