[0002] Soil conditioners are substances used to improve the physical, chemical, and biological properties of soil, regulate soil fertility, and create a favorable soil environment for plant growth. In soil improvement and agricultural production, soil conditioners play a vital role. They can effectively improve soil structure, regulate soil pH, enhance soil fertility, create an excellent environment for crop growth, and thus improve crop yield and quality. Different soil conditions and crops have specific requirements for the particle size of soil conditioners, so grading is necessary during the production process of soil conditioners.

[0010] Preferably, the multi-stage screening structure includes a mounting frame, which is a hollow square frame structure. A positioning rod is provided through the surface of the mounting frame, and the two ends of the positioning rod pass through the surfaces of the two side support frames respectively. Two positioning rods are symmetrically arranged. Three sets of mounting frames and positioning rods are arranged parallel to each other on the surface of the support frames. A No. 1 sieve plate, a No. 2 sieve plate, and a No. 3 sieve plate are fixedly installed on the inner walls of the three mounting frames respectively. The sieve hole diameter of the No. 1 sieve plate, the No. 2 sieve plate, and the No. 3 sieve plate decreases from top to bottom.

[0011] Using the above technical solution, the positioning rod can be used to achieve the positioning and installation of the mounting frame with the No. 1 sieve plate, the No. 2 sieve plate, and the No. 3 sieve plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the soil conditioner grading device:

[0019] 1. This device is equipped with a support frame to support multiple parallel screen plates, and uses positioning rods to limit the screen plates and support frame, performing a multi-stage screening and grading process for soil conditioner. The lower end of the support frame can be engaged and connected in a concave limiting block, which facilitates the loading and unloading of materials into the device.

[0029] 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.

[0030] Please see Figures 1-6This utility model provides a technical solution: a soil conditioner grading device, including a shell 1, a feed hopper 2, a support frame 3, a limiting block 4, a mounting frame 5, a positioning rod 6, a first sieve plate 7, a second sieve plate 8, a third sieve plate 9, an electric push rod 10, a baffle 11, a motor 12, and an eccentric wheel 13.

[0031] The outer shell 1 is a hollow cuboid structure with an open front surface. A feed hopper 2 extends through the upper surface of the outer shell 1, and a discharge port extends through the lower surface. An internal support structure is provided within the outer shell 1. This support structure, via a support frame 3, enables rapid loading and unloading. The support structure includes the support frame 3, which is an H-shaped plate structure. The lower end of the support frame 3 slides into the inner wall of a limiting block 4. The limiting block 4 has a concave cross-section and is fixedly installed on the bottom surface of the outer shell 1. Two parallel limiting blocks 4 form a group, and two groups of limiting blocks 4 are symmetrically arranged. Each group of limiting blocks 4 is slidably engaged with one of the two support frames 3. Electric push rods 10 are fixedly installed on both sides of the outer shell 1. The output ends of the two electric push rods 10 are fixedly connected to both sides of a baffle 11. Plate 11 is slidably installed on the front surface of the outer shell 1. The height of baffle 11 is greater than the height of limit block 4. A multi-stage screening structure is set between the two support frames 3. The multi-stage screening structure realizes the grading and screening of soil conditioner through No. 1 sieve plate 7, No. 2 sieve plate 8 and No. 3 sieve plate 9. The multi-stage screening structure includes mounting frame 5. Mounting frame 5 is a hollow square frame structure. Positioning rod 6 is set through the surface of mounting frame 5. The two ends of positioning rod 6 pass through the surface of the two support frames 3 respectively. There are two positioning rods symmetrically arranged. There are three sets of mounting frames 5 and positioning rods 6 arranged parallel to each other on the surface of support frame 3. No. 1 sieve plate 7, No. 2 sieve plate 8 and No. 3 sieve plate 9 are fixedly installed on the inner wall of the three mounting frames 5 respectively. The sieve hole diameter of No. 1 sieve plate 7, No. 2 sieve plate 8 and No. 3 sieve plate 9 decreases from top to bottom.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, during the grading and sieving of soil conditioner using this device, the multi-stage sieving structure is first installed. Positioning rods 6 are inserted from the surface of the support frame 3 into the round holes on the surface of the mounting frame 5, so that two symmetrical positioning rods 6 penetrate the surfaces of the support frames 3 on both sides, limiting the mounting frame 5. Then, in a top-to-bottom order, sieve plates 7, 8, and 9 are installed on the surface of the support frame 3, ensuring that the sieve hole diameters of sieve plates 7, 8, and 9 decrease from top to bottom. The support frame 3 is then positioned from the inner walls of the limiting blocks 4 on both sides, allowing the support frame 3 to... The No. 1 sieve plate 7, No. 2 sieve plate 8, and No. 3 sieve plate 9 are inserted into the interior of the outer shell 1. The electric push rod 10 is activated, and the electric push rod 10 drives the baffle 11 to slide upward on the front surface of the outer shell 1, blocking the open end of the limiting block 4 and preventing the support frame 3 from sliding out from the open end of the limiting block 4. The soil conditioner to be graded is poured into the outer shell 1 through the feed hopper 2. After the soil conditioner is sieved through the No. 1 sieve plate 7, No. 2 sieve plate 8, and No. 3 sieve plate 9, the soil conditioner of different particle sizes is graded and sieved. The soil conditioner that meets the different particle size requirements falls into the bottom of the outer shell 1 through the corresponding sieve plate and is finally discharged from the outlet.

[0033] A vibration structure is provided below the support frame 3. The vibration structure realizes the up and down vibration of the support frame 3 through the rotating eccentric wheel 13 to increase the screening efficiency. The vibration structure includes a motor 12, which is fixedly installed on the side surface of the outer shell 1. Two eccentric wheels 13 are fixedly installed through the surface of the outer shell 1 at the output end of the motor 12. The two eccentric wheels 13 are in contact with the lower surface of the support frame 3 on both sides respectively.

[0034] like Figure 3 and Figure 6 As shown, during the grading and sieving process of soil conditioner, the motor 12 is started, and the motor 12 drives the eccentric wheel 13 to rotate. The rotating eccentric wheel 13 exerts a force on the lower surface of the support frame 3, pushing the support frame 3 to move upward. After losing the force of the eccentric wheel 13, it descends under the action of gravity. The continuously rotating eccentric wheel 13 can make the support frame 3 vibrate up and down, thereby driving the first sieve plate 7, the second sieve plate 8 and the third sieve plate 9 on the surface to vibrate up and down, thereby improving the grading and sieving efficiency of soil conditioner.

[0035] Working principle: When using this soil conditioner grading device, the soil conditioner enters the device through the feed hopper 2 on the upper surface of the outer shell 1. The soil conditioner passes through the No. 1 sieve plate 7, No. 2 sieve plate 8, and No. 3 sieve plate 9 from top to bottom, thereby achieving grading of soil conditioners with different particle sizes. The soil conditioner is intercepted by the No. 1 sieve plate 7, No. 2 sieve plate 8, and No. 3 sieve plate 9 according to different particle sizes. During the sieving process, the motor 12 drives the eccentric wheel 13 to rotate. The rotation of the eccentric wheel 13 continuously drives the No. 1 sieve plate 7, No. 2 sieve plate 8, and No. 3 sieve plate 9 to vibrate up and down, thereby increasing the sieving efficiency of the soil conditioner and increasing the overall practicality.
