Description
Technical Field
[0001] The utility model relates to the technical field of fine soil screening, in particular to a fine soil screening mechanism before soil improvement. Background Art
[0002] Fine soil generally refers to the part of the soil with a smaller particle diameter, usually including silt and clay. As a component of soil, fine soil plays an important role in the characteristics and uses of soil. Fine soil plays a vital role in the structure of soil. Because fine soil particles are small, they have a large specific surface area, can absorb water and nutrients, and form a soil aggregate structure, which helps the soil retain moisture and provide nutrients required for plant growth. Fine soil also has a certain effect on the air permeability of the soil. Soil with a higher clay content will make the soil denser and affect the air permeability of the soil, while silt is relatively better. The air permeability of the soil plays an important role in the respiration of the root system and the growth of microorganisms in the soil. Understanding the content and properties of fine soil in the soil can help farmers and gardeners develop reasonable soil improvement plans, such as improving the structure and fertility of the soil by applying organic fertilizers, lime, humus, etc., thereby increasing crop yields and quality.
[0003] The fine soil screening mechanism can separate the soil according to particle size during use, but it also has some shortcomings. The existing fine soil screening mechanism has a large shaking amplitude during screening, and the screening is too intense, causing some dead branches and leaves to be broken and cracked and fall into the fine soil, making the fine soil mixed with some broken and small dead branches and leaves, thereby greatly reducing the fine soil screening effect.
[0004] Therefore, it is urgent to provide a fine soil screening mechanism before soil improvement to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is that when the existing fine soil screening mechanism is screening soil, due to the vibration of the mechanism, some dead wood and impurities are cracked and flow out with the fine soil, resulting in impure fine soil after screening.
[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a fine soil screening mechanism before soil improvement, comprising a main body, a bottom frame is fixedly connected to the bottom of the main body, two support frames are fixedly connected to one side of the top of the main body, and a hopper is fixedly connected between the two support frames;
[0007] A support rod is fixedly connected inside the main body, a soil screening mechanism is installed on the top of the main body, a fine soil discharge pipe is fixedly connected to one side of the bottom of the main body, a control mechanism is installed at the bottom of the fine soil discharge pipe, and a soil block discharge pipe is fixedly connected to the other side of the bottom of the main body.
[0008] The utility model is further configured as follows: the soil screening mechanism includes a first motor fixedly connected between the main body and the support rod, a fixed seat is fixedly connected to the top of the support rod, the output end of the first motor is fixedly connected to the drive shaft, and fixed frames are fixedly connected on both sides of the drive shaft, one side of one of the fixed frames is fixedly connected to a fine soil screening net, and one side of the other fixed frame is fixedly connected to a soil block screening net, and the other fixed seat is located on one side of the top of the main body, and the two fixed seats are both rotatably connected to the drive shaft.
[0009] Through the above technical solution, when in use, the first motor between the main body and the support rod is started to rotate, so that the driving shafts inside the two fixed seats rotate, and then the fixed frame will drive the fine soil screening net and the soil block screening net to rotate. At this time, the soil is put into the hopper between the two support frames, and the soil will first slide onto the fine soil screening net for screening, so that the required fine soil is discharged from the fine soil discharge pipe. As the machine rotates, the soil that cannot be screened out will fall onto the soil block screening net and rotate again. Then, the soil larger than the fine soil particles will be discharged from the soil block discharge pipe, and then the soil will be screened out. In the soil being rotated and screened, the screening will be more stable and the speed will be faster during the screening process, thereby improving work efficiency.
[0010] The utility model is further configured as follows: the control mechanism includes a slide groove opened on the inner wall of the fine soil discharge pipe outlet, the inner wall of the slide groove is slidably connected to a plurality of screening rods, a second motor is fixedly connected to one side of the outer wall of the fine soil discharge pipe, a threaded rod is fixedly connected to the output end of the second motor, the outer wall of the threaded rod is rotatably connected to a connecting block, the bottom of the connecting block is rotatably connected to a first connecting rod, the other end of the first connecting rod is rotatably connected to a second connecting rod, the threaded rod passes through the fine soil discharge pipe, the outer walls of the plurality of screening rods are fixedly connected to connecting blocks, and the first connecting rod is rotatably connected to the corresponding second connecting rod.
[0011] Through the above technical scheme, as the fine soil is discharged from the outlet on the fine soil discharge pipe, other impurities will fall onto multiple screening rods, and thus the soil screening is completed. At this time, the first motor is stopped, and the second motor on the outer wall side of the fine soil discharge pipe is turned on to drive the threaded rod to rotate. As the threaded rod rotates, the connecting block on the threaded rod will move in a certain direction, driving multiple screening rods to close, so that other impurities on the screening rods are discharged, thereby ensuring the purity of the fine soil. At the same time, based on the limiting position of multiple screening rods and chutes, the movement of the screening rods is more stable.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The utility model can rotate and screen the soil by designing a simple screening mechanism and a control mechanism, and distinguish the soil blocks from the fine soil. Due to the vibration during screening, other impurities are broken and brought into the fine soil. The control mechanism is used to distinguish the other impurities from the fine soil, thereby ensuring that the fine soil has a higher purity, which greatly improves the beneficial effect of the fine soil screening mechanism;
[0014] 2. The utility model, through the design of a simple control mechanism, can temporarily retain other impurities in the fine soil on the screening rod when the screened fine soil goes out from the discharge port, and can remove other impurities such as dead wood and leaves after the screening, so that the fine soil is purer after screening, and the fine soil processing demand is accelerated, thereby improving work efficiency.

The two fixed seats 602 The interior is rotatably connected with the driving shaft 603. When in use, the first motor 601 between the main body 1 and the support rod 5 is started to rotate, so that the driving shaft 603 inside the two fixed seats 602 rotates, and then the fixed frame 604 will drive the fine soil screening net 605 and the soil block screening net 606 to rotate. At this time, the soil is put into the hopper 4 between the two support frames 3, and the soil will first slide onto the fine soil screening net 605 for screening, so that the required fine soil is discharged from the fine soil discharge pipe 7. As it rotates, the soil that cannot be screened out will fall onto the soil block screening net 606 and rotate again. Then, the soil larger than the fine soil particles will be discharged from the soil block discharge pipe 9, and then the soil will be screened out.
