Problems solved by technology

[0003] 1. Especially before sampling in the field, it is not convenient to remove the weeds on the soil surface through the sampling device, especially when sampling, it is easy to roll the weeds into the inner side of the soil, causing the weeds to be crushed and mixed with the soil on the side of the drill bit, thus The purity of the sampled soil is not high enough, and the detection effect is not accurate enough
[0004] 2. It is not convenient to sample soil at different depths at the same time, which seriously reduces the efficiency of soil sampling and increases manual labor

Embodiment 1

[0033] see Figure 1-2 and Figure 4 , the weeding mechanism 9 includes a rotating shaft 901 bearing connected to the lower front side of the housing bracket 1, and a transmission gear 902 is fixed on the outside of the rotating shaft 901, and a rotating plate 903 is welded on the outside of the rotating shaft 901, and a weeding rake 904 is fixed inside the right side of the rotating plate 903 , the front and rear sides of transmission gear 902 are all meshed with movable rack plate 905, the bottom of weeding rake 904 is in contact with the soil surface, the bottom of movable rack plate 905 and the bottom of shell bracket 1 are sliding structures, and the two movable racks are reciprocated with feet earlier. The rack plate 905 is pushed, so that the movable rack plate 905 slides left and right at the inner bottom of the lifting housing 4, and under the left and right movement of the movable rack plate 905, the transmission gear 902, the rotating shaft 901 and the rotating plat...

Embodiment 2

[0035] see Figure 2-3 and Figure 5-6 The difference from Embodiment 1 is that the upper and lower inner walls of the lifting housing 4 are provided with chute 401, and the lifting and rotating mechanism 5 includes a runner 501 engaged in the inner side of the chute 401, and the outer side of the runner 501 is keyed with a first The sprocket mechanism 502, the inside of the right side of the first sprocket mechanism 502 is keyed to the outside of the top of the soil drill bit 6, the left and right inner walls of the soil drill bit 6 are welded with fixed cylinders 601, and the bottom of the two fixed cylinders 601 are provided with receiving grooves 602, The conveying auger 702 cooperates with the torsion spring 703 to pull upward through the pull rope 701 to form a rotary soil fetching. First, the servo motor 2 is started to drive the screw shaft 3 to rotate, and the rotation of the screw shaft 3 drives the lifting shell 4 to cooperate with the shell bracket 1 to lift. ,Suc...

Embodiment 3

[0037] see image 3 and Figure 6 , the difference from Embodiment 2 is that the mechanism sampling mechanism 8 includes a slide block 801 that is engaged on the left and right inner walls of the soil drill bit 6, and a return spring 802 is installed below the slide block 801, and the slide block 801 is buckled with fingers, and cooperates with the The return spring 802 presses down, and then use a small digging spoon to take out the soil inside the receiving groove 602 for detection.

[0038] The working principle of the present invention is: as Figure 1-2 and Figure 4 As shown, first the whole device is manually placed in the designated place, and then the two movable rack plates 905 are pushed back and forth with the feet, so that the movable rack plates 905 slide left and right at the bottom of the inner side of the lifting housing 4, and the movable rack plates 905 slide left and right at the bottom of the inner side of the lifting housing 4. Under the left and right...

Abstract

The invention discloses a sampling device for soil detection, and the device comprises a shell support; a servo motor is installed at the top of the shell support, a lifting shell is in threaded connection with the outer side of a spiral shaft, a lifting rotating mechanism is arranged on the inner side of the lifting shell, and a drill bit is connected to the lower portion of the right side of the lifting shell through a bearing; sampling mechanisms capable of sampling soil with different depths at the same time are arranged on the left and right inner sides of the drill bit, and sampling mechanisms capable of taking out all the soil sampled on the inner side of the drill bit are mounted on the left and right outer sides of the drill bit; and a weeding mechanism capable of removing weeds on the surface of the soil sampling area is arranged on the lower portion of the left side of the shell support. According to the invention, the lifting rotating mechanism and the sampling mechanism are arranged, so soil at different depths can be effectively sampled, and the manual labor force is greatly reduced; meanwhile, the whole soil detection sampling efficiency is improved, and the overall practicability and convenience are improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a sampling device for soil testing. Background technique [0002] The implementation of precision agriculture mainly includes three links: the collection of farmland information, information management and decision-making, and variable operations. The development of precision agriculture takes the rapid and accurate acquisition and processing of farmland spatial distribution information as technical support. The link of farmland information collection It is an important basis for the implementation of precision agriculture. However, the backwardness of field information collection technology has become one of the main obstacles to the implementation of precision agriculture. Therefore, the development of field information collection technology is the premise and basis for the development of precision agriculture. Among them, the rapid and accurate soil sampling device is It is an impor...
