Technical Field

[0001] The utility model relates to the technical field of electric soil drills, in particular to an electric soil drill capable of quantitative sampling. Background Art

[0002] Electric soil auger is an effective experimental tool for agricultural researchers studying soil distribution, organic matter content, soil moisture content, and other aspects at different depths. Existing soil auger sampling methods suffer from overly simple sampling tubes that cannot be adjusted to varying depths. This cumbersome and inefficient operation requires changing the tubes when different soil samples are needed. Furthermore, most soil samples tend to scatter below the tubes after sampling, resulting in insufficient soil sample volume and affecting measurement accuracy. Therefore, the present invention provides an electric soil auger capable of quantitative sampling. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the existing soil drill in the prior art, that when sampling soil, the sampling tube is too simple and the depth of the sampling tube cannot be changed according to needs. When different amounts of soil samples need to be taken, the sampling tube needs to be replaced, which is cumbersome and has low work efficiency. At the same time, after most sampling tubes are sampled, the soil below is easily scattered, resulting in insufficient sampled soil volume, which easily affects the accuracy of measurement. The utility model proposes an electric soil drill that can perform quantitative sampling.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an electric soil drill capable of quantitative sampling, comprising a loading plate, the side wall of the loading plate is fixedly connected to a handrail frame, and a motor is installed on the surface of the loading plate, the output end of the motor passes through the surface of the loading plate and is fixedly connected to a rotating rod, the lower end of the rotating rod is fixedly connected to a soil drilling barrel, and the lower end of the soil drilling barrel is provided with loosening teeth, the inner wall of the soil drilling barrel is provided with a soil sampling cavity, and the lower end of the soil sampling cavity is rotatably connected to two baffles, the surfaces of the two baffles are fixedly connected to adjustment blocks, the interior of the adjustment block is slidably connected to a steel rope, and one side of the adjustment block is threadedly connected to a bolt, one end of the steel rope passes through the surface of the baffle, and the other end is fixedly connected to a push plate, the inner wall of the soil sampling cavity is provided with four sliding grooves, and the inner wall of the sliding groove is slidably connected to the side wall of the push plate.

[0005] Preferably, both sides of the loading plate are fixedly connected with a fixing plate, the lower end of the fixing plate is fixedly connected with a pressure rod, and the surface of the pressure rod is slidably connected with a sliding cylinder, the lower surface of the inner wall of the sliding cylinder is fixedly connected with a spring, and the lower end of the sliding cylinder is fixedly connected to the support plate.

[0006] Preferably, a foot pedal is rotatably connected to the surface of the support plate, and a plurality of cone columns are fixedly connected to the lower surface of the foot pedal.

[0007] Preferably, a spirit level is fixedly connected to the surface of the fixing plate.

[0008] Preferably, four sliding rods are fixedly connected to the upper surface of the push plate, and the four sliding rods pass through the upper end of the drilling tube and are fixedly connected to the annular pressure plate.

[0009] In summary, this application has the following beneficial technical effects:

[0010] 1. In the utility model, the motor drives the soil drill barrel to rotate, so that the loosening teeth stir the soil. The loosened soil enters the soil sampling cavity. At the same time, the soil pushes the push plate to move upward. When the push plate moves upward, the baffle is driven to rotate by the steel rope, thereby closing the pipe mouth of the soil sampling cavity to prevent the soil sample inside from being scattered when the soil drill barrel is taken out. The length of the steel rope can be adjusted by adjusting the block and the bolt, thereby adjusting the length of the push plate dividing the soil sampling cavity to achieve the effect of quantitative sampling.

[0011] 2. In the present invention, the worker presses the handrail downward, and at the same time the sliding rod slides downward in the sliding tube and squeezes the spring. The reaction force generated by the deformation of the spring and the support plate can play a supporting role. Then the worker presses the pedal with his feet to insert the cone column on the pedal into the soil, thereby improving stability during operation. BRIEF DESCRIPTION OF THE DRAWINGS
