Description

Technical Field

[0001] The utility model belongs to the technical field of soil detection, and specifically refers to a heavy metal detection device for farmland soil. Background Technique

[0002] Traditional heavy metal detection devices for farmland soil usually require pre-treatment of soil samples. Unscreened farmland soil contains impurities such as hard stones and plant residues, which will interfere with the subsequent detection process. Therefore, traditional heavy metal detection devices for farmland soil lack a screening mechanism, and the screening mechanism will age and be damaged due to continuous use of the sieve plate, and need to be replaced and maintained regularly. Content of the Utility Model

[0003] In order to solve the problems that the traditional heavy metal detection device for farmland soil lacks a screening mechanism, and the sieve plate on the screening mechanism needs to be replaced and maintained regularly due to aging and damage, the utility model provides a heavy metal detection device for farmland soil.

[0004] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: A heavy metal detection device for farmland soil, including a collection tank and a heavy metal detector. A bottom plate is provided at the bottom of the collection tank. An L-shaped support plate is provided on the bottom plate. A chute is opened at the top of the L-shaped support plate. A screening mechanism is slidably arranged on the chute. A filter box is slidably arranged on the L-shaped support plate. A pull-out sieve plate is inserted on one side of the filter box. The collection tank is arranged below the filter box. A track is provided on the collection tank. An L-shaped sliding plate is slidably arranged on the track. The heavy metal detector is arranged in the collection tank and installed on the L-shaped sliding plate.

[0005] As a preferred technical solution of the utility model, the screening mechanism includes a rotary motor, a first connecting rod, a second connecting rod and an L-shaped slider. The rotary motor is arranged on the L-shaped support plate. The output end of the rotary motor rotatably penetrates through the L-shaped support plate. One end of the first connecting rod is connected to the output end of the rotary motor. One end of the second connecting rod is rotatably arranged on the other end of the first connecting rod through a shaft. The L-shaped slider is slidably arranged in the chute and the end is connected to the filter box. The other end of the second connecting rod is rotatably arranged on the L-shaped slider through a shaft.

[0006] As a preferred technical solution of the utility model, corresponding slide rails two are provided on the inner side wall of the filter box. The pull-out sieve plate is slidably arranged between the two slide rails two.

[0007] As a preferred technical solution of the present utility model, a reset assembly is correspondingly arranged on the side wall of the filter box. The reset assembly includes a fixed rod, a linkage plate, and a torsion spring. The fixed rod is fixedly arranged on the filter box. The linkage plate is movably sleeved on the fixed rod. The top end of the linkage plate is attached to the side wall of the filter box. The bottom end of the linkage plate is attached to the side wall of the pull-out sieve plate. The torsion spring is sleeved outside the fixed rod. One end of the torsion spring is connected to the fixed rod, and the other end of the torsion spring is connected to the linkage plate.

[0008] As a preferred technical solution of the present utility model, one end of the collection trough far from the bottom plate is inclined. A support block is correspondingly arranged on the bottom plate. The top end of the support block contacts the inclined surface of the collection trough.

[0009] As a preferred technical solution of the present utility model, a slide rail I is arranged on the side wall of the L-shaped support plate. The filter box is slidably installed on the slide rail I.

[0010] Compared with the prior art, the present utility model adopts the above structure to achieve the following beneficial effects:

[0011] 1. Through the setting of the sieving mechanism, when the rotary motor is turned on, the output end of the rotary motor drives the connecting rod I to rotate, thereby driving the L-shaped slider to perform reciprocating linear motion in the chute, and then driving the reciprocating sieving of the filter box, which is convenient for sieving and filtering the farmland soil, improving the sieving efficiency of impurities such as hard stones and plant residues in the farmland soil, and ensuring the accuracy of the heavy metal detection results in the later farmland soil;

[0012] 2. Through the setting of the reset assembly, when the pull-out sieve plate needs to be installed on the filter box, the linkage plate is rotated, and the pull-out sieve plate is slidably installed on the filter box. The torsion spring will generate a reset torsional force, driving the bottom end of the linkage plate to fit against the side wall of the pull-out sieve plate, thereby firmly fixing the pull-out sieve plate on the filter box. When the pull-out sieve plate needs to be removed from the filter box, the linkage plate is rotated, and the pull-out sieve plate is slid out of the filter box, which is convenient for regular replacement and maintenance of the pull-out sieve plate.
