Problems solved by technology

[0004] 1. After the sampling is completed, it is necessary to manually unscrew the soil extraction pipe of the pipe shoe, and then take the soil out of the ring knife. The sampling process is complicated and the efficiency is low.
[0005] 2. When the above-mentioned soil sampling device encounters a relatively loose soil layer, when the ring cutter is filled with soil and the lifting unit drives the earth taker to rise, the soil in the ring cutter will fall from the lower end of the earth taker, which is difficult to ensure The soil can be removed from the soil layer smoothly

Embodiment 1

[0048] see Figure 1-Figure 3 , a soil sampling device in this embodiment, comprising a mounting base 1, three sampling clips 2 arranged below the mounting base 1 for grabbing soil samples and a sampling drive mechanism; wherein, the three sampling clips 2 are arranged along the The sampling cylinders are evenly distributed in the circumferential direction, and the sampling drive mechanism is used to drive the sampling clips 2 to move closer to each other and move away from each other along the radial direction.

[0049] see Figure 1-Figure 7 , the sampling driving mechanism includes a driving source arranged above the mounting base 1, and there is a device between the driving source and the mounting base 1 for transmitting the power of the driving source to each sampling clamp 2 and prompting three A synchronous transmission assembly 3 for synchronous movement of two sampling clips; the synchronous transmission assembly 3 includes a transmission plate 3-1 arranged on the to...

Embodiment 2

[0070] see Figure 16 , other structures in this embodiment are the same as in Embodiment 1, the difference is that: the synchronous transmission assembly 3 includes a screw 3-7, a screw nut 3-8 and 3 that cooperate with the screw 3-7 A connecting rod 3-9 arranged between the screw nut 3-8 and the slider 3-6; wherein, the upper end of the screw rod 3-7 is connected to the rotating shaft of the sampling drive motor 4, and the lower end is connected to the The mounting base 1 is connected in rotation; one end of the connecting rod 3-9 is hinged to the screw nut 3-8, and the other end is hinged to the slider 3-6. Through the above-mentioned synchronous transmission assembly 3, the sampling clip 2 can be moved towards and away from each other synchronously along the radial direction of the sampling cylinder, realizing the functions of the sampling clip 2 clamping and loosening the soil.

Embodiment 3

[0072] see Figure 17, the other structures in this embodiment are the same as in Embodiment 1, the difference is that the guide assembly includes a guide groove 3-10 arranged on the mounting seat 1 and a sliding fit with the guide groove 3-10 Sliding block 3-11; wherein, the guide groove 3-10 extends towards the center of the sampling cylinder, the lower end of the transmission rod 3-2 is fixedly connected to the upper end of the sliding block 3-11, and the sampling clip 2 The upper end of is connected with the lower end of described sliding block 3-11. By setting the guide assembly, it can ensure that the sampling clip 2 can move along the radial direction of the mounting base 1, and at the same time, it is also beneficial for the sampling clip 2 to move more stably when clamping and loosening the soil.

Abstract

The invention discloses a soil sampling device. The soil sampling device comprises a mounting base, a plurality of sampling clamps arranged below the mounting base and used for grabbing sampled soil,and a sampling driving mechanism, wherein the plurality of sampling clamps are uniformly distributed in the circumferential direction to form a sampling cylinder, and the sampling driving mechanism isused for driving the sampling clamps to move close to each other and far away from each other along the radial direction, wherein the sampling driving mechanism comprises a driving source arranged above the mounting base, and a synchronous transmission assembly used for transmitting the power of the driving source to each sampling clamp and promoting the plurality of sampling clamps to do synchronous movement is arranged between the driving source and the mounting base. The device is simple and convenient in the soil collecting process, can realize automatic soil taking, and is high in efficiency; the device can adapt to soil under different conditions, and when loose soil is collected, sample soil cannot fall off in the collecting process.

Description

technical field [0001] The invention relates to soil sampling equipment, in particular to a soil sampling device and a soil sampling vehicle. Background technique [0002] With the development of our society, people pay close attention to food safety, and it is particularly important to ensure food safety. Due to the increasingly serious soil pollution in our country, if the soil is polluted in the farmland or orchard, the harmful substances in the soil will be absorbed by the crops and fruit trees, and finally affect human health. Therefore, it is extremely important for soil sampling analysis. [0003] At present, the way of soil sampling has gradually transitioned from manual sampling to mechanical sampling. For example, the invention patent application with the application publication number CN109682634A discloses a soil adjustment drive mechanism, which includes a mobile trolley, a soil fetcher, a lifting drive unit, a rotary drive unit and a connecting frame; Soil p...
