Description

[Technical Field]

[0001] This invention relates to the technical field of soil testing, and in particular to the technical field of a soil testing and processing device. [Background Technology]

[0002] Soil environmental monitoring refers to determining environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we usually refer to it, generally includes technical aspects such as sampling site selection, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation.

[0003] When conducting soil testing, the collected clod soil samples must first be crushed. Then, the crushed soil is screened to remove stones and other debris to avoid affecting the test results.

[0004] Chinese invention patent application number CN202111088824.5 discloses a crushing mechanism for soil testing. A second drive motor further drives a first transmission shaft fixedly connected to its output shaft to rotate. The first transmission shaft further drives a first bevel gear fixed to its surface to rotate. The first bevel gear further drives a second bevel gear meshing with it to rotate. The second bevel gear further drives the second transmission shaft fixedly connected to its central shaft to rotate. The second transmission shaft further drives a third bevel gear fixed to its bottom end to rotate. The third bevel gear further drives a fourth bevel gear meshing with it to rotate. The double-threaded screw, which is fixedly connected to its central axis, rotates further. The double-threaded screw then moves the first nut seat sleeved on its surface. The first nut seat, through the first connecting rod hinged to it, drives the lower crushing disc to move up and down in a reciprocating motion. Thus, the lower and upper crushing discs cooperate to crush the soil that enters the crushing chamber through the feed inlet. The crushing method is compression. When there are stones in the lumpy soil sample, the stones will be crushed, and the crushed stone powder will mix into the soil sample, affecting the test results. Furthermore, since the soil itself contains moisture, it is easy to clump after being compressed, affecting the subsequent screening efficiency. [Summary of the Invention]

[0005] The purpose of this invention is to solve the problems in the prior art and to propose a soil testing and processing device that can improve the accuracy of testing results and screening efficiency.

[0006] To achieve the above objectives, the present invention proposes a soil testing and processing device, comprising a cylinder, a screen, a dispersing device, a drive mechanism I, and a base. The base is provided with the cylinder and the drive mechanism I. The screen is provided inside the cylinder. The drive mechanism I is provided with a dispersing device that can enter the cylinder. The dispersing device includes a cover plate, a drive mechanism II, a rotating shaft, a mounting plate, and several telescopic rods. The cover plate is provided with the rotating shaft. The lower end of the rotating shaft is provided with a mounting plate that can enter the cylinder. The lower end of the mounting plate is provided with telescopic rods. The cover plate is provided with the drive mechanism II that drives the rotating shaft to rotate.

[0007] Preferably, the telescopic rod includes a cylinder, a piston, a spring I, and a rod. The piston is housed inside the cylinder, and a rod extending from the lower end of the piston extends from the lower end of the cylinder. A spring I is fitted onto the rod between the piston and the lower end of the cylinder. A cavity communicating with the cylinder is provided on the mounting plate. A channel I communicating with the cavity is provided on the rotating shaft. A rotary joint is provided at the upper end of the channel I. The rotary joint is connected to a compressed air supply pipe through a three-way valve.

[0008] Preferably, the cylinder body is provided with a positioning ring located below the piston body.

[0009] Preferably, the rod body is provided with channel II, and the lower end of the rod body is provided with a through hole communicating with channel II.

[0010] Preferably, the upper end of the rod is provided with a sleeve that communicates with channel II. The internal space of the sleeve is conical. The sleeve contains a conical plug and a bracket located below the conical plug. A spring II is provided between the conical plug and the bracket.

[0011] Preferably, a heater is provided on the connecting pipe between the rotary joint and the three-way valve.

[0012] Preferably, the lower end of the rod is arc-shaped.

[0013] Preferably, the drive mechanism II includes a servo motor, a drive pulley, a driven pulley, and a synchronous belt. The drive end of the servo motor is provided with a drive pulley, the driven pulley is provided on the rotating shaft, and the drive pulley and the driven pulley are provided with a synchronous belt.

[0016] The beneficial effects of this invention are as follows: This invention uses several telescopic rods to break up soil sample blocks. When a telescopic rod hits a stone in the soil sample block, the stone blocks the rod from extending further. However, the rods that do not hit a stone can continue to extend and break up the soil sample block. This ensures that the soil block is broken up without crushing the stone. After the soil block is broken up, the drive mechanism II drives the rotating shaft to rotate. The rotating shaft drives the telescopic rods to rotate through the mounting plate. The telescopic rods further disperse the broken soil and sieve it through a screen. Compared with the prior art, this invention can improve the accuracy of the test results and the screening efficiency.

[0017] Compressed air is heated by a heater and then passes sequentially through a rotary joint, channel I, cavity, cylinder, sleeve, channel II, and through hole to dry the soil sample, thereby improving drying efficiency and further enhancing screening efficiency.

The base 5 is provided with insertion slots 10 that correspond one-to-one with and cooperate with the support feet 9.

[0024] The working process of this invention:

[0025] In the operation of this soil testing and processing device, a soil sample block is placed on a sieve 2. Then, the electric push rod 41 retracts, driving a cover plate 30 downwards via a connecting body 42 to cover the upper end of the cylinder 1. The downward movement of the cover plate 30 drives a mounting plate 33 downwards via a rotating shaft 32. The mounting plate 33 then drives a telescopic rod 34 downwards into the cylinder 1. Next, the heater 39 is activated, and the three-way valve 38 is adjusted to connect the rotary joint 37 to the compressed air supply pipe. Compressed air passes sequentially through the three-way valve 38, heater 39, rotary joint 37, channel I36, and cavity 35 before entering the cylinder 341. When the force of the compressed air on the piston 342 exceeds the force of the spring I343, the piston 342 moves downwards under the action of the compressed air, driving the rod 344 downwards. When the soil is crushed, the piston body 342 is blocked by the positioning ring 345 and cannot continue to move downward. The pressure of the compressed air in the cylinder 341 increases. When the force of the compressed air on the conical plug 3411 is greater than the force of the spring II 3410, the conical plug 348 moves downward. A gap appears between the conical plug 3411 and the sleeve 348. The compressed air passes through the sleeve 348, the channel II 346 and the through hole 347 in sequence. The heated air blown out from the through hole 347 dries the soil. Then, the servo motor 311 is started to drive the rotating shaft 32 to rotate through the cooperation of the driving pulley 312, the driven pulley 313 and the synchronous belt 314. The rotating shaft 32 drives the telescopic rod 34 to rotate through the mounting plate 33. The telescopic rod 34 pulls the crushed soil to further disperse it. It is then screened through the screen 2. The soil sample that passes through the screen 2 is discharged through the discharge port 8.

[0026] When the rod 344 hits a stone in the soil sample, the stone blocks the rod 344 from extending further. However, the rod 344 that does not hit the stone can continue to extend and crush the soil sample, thus ensuring that the soil is crushed without crushing the stone.

[0027] When it is necessary to move the position and crush again, adjust the three-way valve 38 to connect the rotary joint 37 with the other port of the three-way valve 38. At this time, the compressed air in the cylinder 341 is discharged, and the spring II 3410 pushes the conical plug 3411 to move upward to seal the sleeve 348. Then, the spring I 343 drives the rod 344 to move upward to return to its original position through the piston body 342. Then, the servo motor 311 is started to drive the rotating shaft 32 to rotate by the required amount through the cooperation of the driving pulley 312, the driven pulley 313 and the synchronous belt 314. Then, the control rod 344 is extended to crush again according to the above operation.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
