Through soil analysis, farmers can be guided to apply fertilizers rationally, improve the soil, and increase crop yield and quality.
[0003] The utility model patent with authorization announcement number CN220671073U discloses "An agricultural soil analysis pretreatment device". By installing a grinding plate on a grinding cover through a rotating shaft and installing a rocker arm on the rotating shaft, the device aims to reduce labor intensity and improve work efficiency. At the same time, the grinding plate is designed to be able to slide axially relative to the rotating shaft. During the grinding operation, it can also achieve the purpose of squeezing and crushing fresh soil samples, thereby further improving grinding efficiency.
[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: Although the agricultural soil analysis pretreatment device can improve the grinding efficiency of agricultural soil samples, due to the lack of a sieving structure, the particle size of the ground soil sample will be uneven due to uneven distribution before grinding or insufficient grinding time, which may cause the analysis results to be affected by the particle size effect and thus deviate.

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0026] Please see Figure 1-5 An agricultural soil analysis pretreatment device with a screening component includes a treatment box 1, a grinding component 2, a screening component 3, and a disassembly component 4.
[0027] The screening assembly 3 includes a dual-shaft motor 301, the output shaft of which is fixedly connected to a transmission rod 302. A first pulley 303 is fixedly connected to the transmission rod 302. An installation groove 304 is provided on the side wall of the processing box 1. A second pulley 305 is rotatably connected inside the installation groove 304. A transmission belt 306 is connected between the first pulley 303 and the second pulley 305. A cam 307 is installed on the side of the second pulley 305 near the inside of the processing box 1. A screening frame 308 is placed inside the processing box 1. Connecting rods 309 are fixedly connected to both sides of the screening frame 308. A chamber 310 is provided inside the side wall of the processing box 1. A slider 311 is slidably connected inside the chamber 310. A pusher 312 is fixedly connected to the top of the slider 311. A spring 313 is fixedly connected to the top of the slider 311.
[0028] The disassembly assembly 4 includes a handle 401, and push-pull through holes 402 on both the left and right sides of the processing box 1 are adapted to the movement trajectory of the handle 401.
[0029] Specifically, the grinding assembly 2 includes a grinding bucket 201, a grinding motor 202 is fixedly connected to the top of the processing box 1, a grinding disc 203 is fixedly connected to the output shaft of the grinding motor 202, and a feed pipe 204 is fixedly connected to the top of the processing box 1.
[0030] Through the above technical solution, starting the grinding motor 202 can drive the grinding disc 203 to rotate. By utilizing the cooperation between the grinding disc 203 and the grinding bucket 201, the grinding pretreatment of agricultural soil samples can be achieved.
[0031] Specifically, the grinding bucket 201 is fixedly connected inside the processing box 1, the grinding disc 203 extends to the inside of the grinding bucket 201, and the bottom of the feed pipe 204 extends into the processing box 1 and is located above the gap between the grinding bucket 201 and the grinding disc 203.
[0032] By extending the bottom of the feed pipe 204 above the gap between the grinding hopper 201 and the grinding disc 203 through the above technical solution, agricultural soil samples can be prevented from falling onto the surface of the grinding hopper 201, thus preventing them from being ground.
[0033] Specifically, two support blocks are fixedly connected to the rear side of the processing box 1, and the transmission rod 302 passes through the support blocks and is rotatably connected to them.
[0034] Through the above technical solution, the two support blocks provide support for the transmission rod 302, preventing damage to the transmission rod 302 due to its suspended installation.
[0035] Specifically, a rotating shaft extending into the processing box 1 is rotatably connected inside the mounting slot 304, a second pulley 305 is fixedly connected to the outside of the rotating shaft, and the other side of the rotating shaft is fixedly connected to the cam 307.
[0036] Through the above technical solution, the first pulley 303, the second pulley 305 and the transmission belt 306 work together to drive the rotating shaft to rotate, and then drive the cam 307 to rotate, and work with the spring 313 to make the sieve frame 308 vibrate up and down, so as to achieve the purpose of sieving agricultural soil samples.
[0037] Specifically, a moving cavity adapted to the moving trajectory of the connecting rod 309 is provided in the side wall of the processing box 1, and the push seat 312 extends into the moving cavity and fits against the bottom of the connecting rod 309.
[0038] Through the above technical solution, the opening of the moving cavity restricts the moving direction and moving distance of the connecting rod 309 and the screening frame 308.
[0039] Specifically, the processing box 1 has a door hinged to the front side, and the processing box 1 has a receiving frame 5 located below the screening frame 308 inside. The side wall of the processing box 1 has a rod retraction hole that communicates with the moving cavity. The size of the rod retraction hole is adapted to the moving trajectory of the connecting rod 309.
[0040] Through the above technical solution, the receiving frame 5 is used to receive agricultural soil samples after screening. When the screening frame 308 needs to be replaced, the connecting rod 309 can be removed from the rod removal hole to disassemble the screening frame 308.
[0041] In operation, the grinding motor 202 is first started to drive the grinding disc 203 to rotate inside the grinding hopper 201. Then, the agricultural soil sample is fed into the feed pipe 204. Under the action of the feed pipe 204, the agricultural soil sample falls into the gap between the grinding hopper 201 and the grinding disc 203 for pre-grinding. Subsequently, the agricultural soil sample falls onto the sieve frame 308. At this time, the dual-shaft motor 301 is started to drive the transmission rods 302 on both sides to rotate. Under the transmission of the first pulley 303, the second pulley 305, and the transmission belt 306, the rotating shaft drives the cam 307 to rotate. The sieve frame 308 vibrates up and down in conjunction with the slider 311, push seat 312 and spring 313 to sieve agricultural soil samples by particle size. Agricultural soil samples that meet the standards fall into the receiving frame 5 and are collected. When the sieve frame 308 needs to be replaced, the dual-shaft motor 301 is turned off, the rotation of the cam 307 is stopped, the handle 401 is held and moved down along the push-pull through hole 402, and the connecting rod 309 is lowered from the moving cavity into the push rod hole. The box door can be opened and the sieve frame 308 can be pulled out forward to replace it, so as to sieve agricultural soil samples of different particle sizes.
