Description
Technical Field
[0001] The utility model relates to the technical field of soil screening, in particular to a soil rapid screening device. Background Art
[0002] Soil refers to a layer of loose material on the earth's surface, which is composed of various granular minerals, organic matter, moisture, air, microorganisms, etc., and can grow plants. Soil is composed of minerals weathered from rocks, organic matter produced by the decomposition of plant and animal residues and microorganisms, soil organisms, as well as moisture, air, and oxidized humus.
[0003] When the existing soil is reprocessed, it is often necessary to screen the soil to obtain soil with a certain fineness. When screening the soil, a corresponding screening device needs to be used. At present, most screening devices are composed of a fixed frame and a sieve plate. The soil is directly guided onto the sieve plate, and the rapid screening is realized by shaking the sieve plate to improve the screening efficiency. However, in the actual screening process, the soil on the surface of the guiding sieve plate is prone to caking, which affects the screening effect. At the same time, when guiding the soil onto the sieve plate, the soil is likely to locally aggregate on the surface of the sieve plate, which will further affect the screening effect. Therefore, we propose a soil rapid screening device. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a soil rapid screening device to solve the problems raised in the background art.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A soil rapid screening device includes a base. A sieve plate is arranged on the upper side of the base. Both sides of the top of the base are fixedly provided with support plates. Both sides of the top of the support plates are fixedly provided with first springs. The outer ends of the first springs are fixedly connected to the corresponding positions at the bottom of the sieve plate. Vibration motors are fixedly arranged on both side walls of the sieve plate;
[0006] A crushing assembly is connected to the top of the sieve plate. The crushing assembly includes end plates. One side wall of the end plate is fixedly connected to the top of the base through side plates. Both sides of the bottom of the end plate are provided with movable blocks. A plurality of uniformly distributed tapered rods are connected to the bottom of the movable blocks. Both sides of the top of the end plate are fixedly provided with electric push rods. The push rods of the electric push rods movably penetrate through the end plates and are fixedly connected to the corresponding movable blocks.
[0007] By adopting the above technical solution, the sieve plate is driven to vibrate by a vibration motor, and then the soil is guided to the surface of the sieve plate so that the soil rolls on the sieve plate and is screened. During screening, the soil rolling on the sieve plate is crushed by a crushing assembly to avoid affecting the screening effect due to soil agglomeration, and the movable block is pushed down alternately by two electric push rods, thereby achieving continuous and uninterrupted crushing of the soil on the sieve plate.
[0008] As a preferred embodiment of the utility model, brackets are fixed on both sides of one side wall of one support plate, a carrier plate is fixed at the end of the bracket, a servo motor is fixed on the top of the carrier plate, and a transmission shaft of the servo motor movably passes through the carrier plate and is fixedly connected to a toggle plate.
[0009] By adopting the above technical solution, when guiding the soil to the surface of the screen plate, the servo motor can be used to drive the toggle plate to move back and forth, so that the soil on the guide screen plate can be evenly spread, so that the soil is evenly distributed when rolling and screening on the screen plate, thereby avoiding the situation where a large amount of material rolls locally, thereby avoiding the accumulation that affects the screening effect, and further improving the screening effect.
[0010] As a preferred embodiment of the present invention, the bottom of the shifting plate is close to the surface of the sieve plate but not in contact with it.
[0011] By adopting the above technical solution, it can be ensured that when the soil on the screen plate is moved, wear between the screen plate and the moving plate can be avoided.
[0012] As a preferred embodiment of the utility model, a slot is provided at the bottom of the movable block corresponding to the conical rod, the conical rod is inserted into the slot and fixedly connected with a second spring, and the other end of the second spring is fixedly connected to the end surface of the inner cavity of the slot.
[0013] By adopting the above technical solution, when the cone rod descends to crush and pressurize the soil, the second spring can be compressed for buffering, thereby avoiding aggravated damage to the cone rod and the screen plate caused by long-term rigid impact.
[0014] As a preferred embodiment of the present invention, the width of the inner cavity of the sieve plate is greater than the length of the movable block.
[0015] By adopting the above technical solution, there is no spatial obstacle when the movable block descends.
[0016] As a preferred implementation mode of the utility model, limiting rods are fixed on both sides of the top of the movable block, and the limiting rods movably penetrate the end plates.
[0017] By adopting the above technical solution and setting the limit rod, the moving trajectory of the movable block can be limited, ensuring high lifting stability.
[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0019] A soil rapid screening device of the technical solution of the present application is provided with a crushing assembly on the top of the screen plate, so that when the soil is rolled and screened on the screen plate, the crushing assembly can be used to crush the agglomerated soil, thereby ensuring that the screening effect is improved during the rapid screening process;
[0020] The movable blocks on both sides can move up and down alternately, so that the cone rods on both sides can continuously and uninterruptedly crush the soil on the screen plate to avoid the situation of missing crushing;
[0021] By using the servo motor to drive the moving plate to move back and forth when guiding the soil to the surface of the screen plate, the soil on the guide screen plate can be moved and spread evenly, so that the soil is evenly distributed when rolling and screening on the screen plate, thereby avoiding the situation where a large amount of material rolls locally, thereby avoiding accumulation that affects the screening effect, and further improving the screening effect.

[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: a soil rapid screening device, including a base 1, a screening plate 11 is arranged on the upper side of the base 1, both sides of the top of the base 1 are fixedly provided with support plates 12, both sides of the top of the support plates 12 are fixedly provided with first springs 13, the outer ends of the first springs 13 are fixedly connected with the corresponding positions at the bottom of the screening plate 11, and vibration motors 14 are fixedly arranged on both side walls of the screening plate 11;
[0032] The top of the screening plate 11 is connected with a crushing component 2. The crushing component 2 includes end plates 21. One side wall of the end plates 21 is fixedly connected with the top of the base 1 through side plates 15. Both sides of the bottom of the end plates 21 are provided with movable blocks 22. A plurality of uniformly distributed tapered rods 24 are connected to the bottom of the movable blocks 22. Both sides of the top of the end plates 21 are fixedly provided with electric push rods 23. The push rods of the electric push rods 23 movably penetrate through the end plates 21 and are fixedly connected with the corresponding movable blocks 22;
[0033] During actual use, the vibration motor 14 drives the screening plate 11 to vibrate, and then the soil is guided to the surface of the screening plate 11, so that the soil rolls on the screening plate 11, and the soil is screened. When screening, the crushing component 2 is used to crush the soil rolling on the screening plate 11, avoiding the influence of soil caking on the screening effect, and using two electric push rods 23 to alternately push the two movable blocks 22 to descend, so as to continuously and uninterruptedly crush the soil on the screening plate 11.
[0034] Furthermore, both sides of the top of the movable block 22 are fixedly provided with limiting rods 25. The limiting rods 25 movably penetrate through the end plates 21. The arrangement of the limiting rods 25 enables the movement track of the movable block 22 to be limited, ensuring high lifting stability.
[0035] Furthermore, the inner cavity width of the screening plate 11 is greater than the length of the movable block 22, so that there is no spatial obstacle when the movable block 22 descends.
[0036] It is worth introducing that slots are opened at the positions corresponding to the tapered rods 24 at the bottom of the movable block 22. The tapered rods 24 are inserted into the slots and fixedly connected with a second spring 26. The other end of the second spring 26 is fixedly connected with the inner cavity end face of the slot;
[0037] When the tapered rod 24 descends to crush and press the soil, the second spring 26 can be compressed for buffering, so as to avoid the damage of the tapered rod 24 and the screening plate 11 caused by long-term rigid impact.
[0038] Such as Figure 1 and 2As shown; a bracket 3 is fixed on both sides of one side wall of one support plate 12, a carrier plate 31 is fixed at the end of the bracket 3, a servo motor 32 is fixed on the top of the carrier plate 31, and a drive shaft of the servo motor 32 movably penetrates the carrier plate 31 and is fixedly connected to a toggle plate 33;
[0039] In actual use, when guiding the soil to the surface of the screen plate 11, the servo motor 32 can be used to drive the toggle plate 33 to move back and forth, so that the soil on the guide screen plate 11 can be evenly spread, so that the soil is evenly distributed when rolling and screening on the screen plate 11, thereby avoiding the situation where a large amount of material rolls locally, thereby avoiding accumulation that affects the screening effect, and further improving the screening effect.
[0040] Furthermore, the bottom of the shifting plate 33 is close to the surface of the sieve plate 11 and is not in contact with the surface, thereby ensuring that when the soil on the sieve plate 11 is shifted, wear between the sieve plate 11 and the shifting plate 33 can be avoided.
[0041] The implementation principle of a soil rapid screening device of the present application is as follows: in actual use, the sieve plate 11 is driven to vibrate by a vibration motor 14, and then the soil is guided to the surface of the sieve plate 11, so that the soil rolls on the sieve plate 11 and the soil is screened. During screening, the soil rolling on the sieve plate 11 is crushed by a crushing assembly 2 to avoid affecting the screening effect due to soil agglomeration, and the two electric push rods 23 are used to alternately push the movable block 22 down, so that the soil on the sieve plate 11 can be continuously and uninterruptedly crushed. When the soil is guided to the surface of the sieve plate 11, the servo motor 32 can be used to drive the toggle plate 33 to move back and forth, so that the soil on the guided sieve plate 11 can be toggled and spread evenly, so that the soil is evenly distributed when rolling and screening on the sieve plate 11, thereby avoiding a large amount of locally rolling materials, thereby avoiding the situation where accumulation affects the screening effect, and further improving the screening effect.
[0042] In addition, the components included in the soil rapid screening device of the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle part of the device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive monitoring computers and power supplies, are connected through wires. The specific connection means should refer to the following working principle. The electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.
