Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to an information investigation and collection device for soil general survey. Background Art

[0002] The growth of plants requires a good soil environment. Therefore, it is necessary to conduct a general survey of the soil. By detecting the soil, different plants can be adapted according to the characteristics of different soils. At the same time, it can also help users understand the basic situation of the soil in time to ensure an ideal growth environment for plants.

[0003] The Chinese patent with the publication number CN219301993U discloses a soil detection device for soil general survey. This device can clean the outer wall of the sampling tube by setting structures such as an electric telescopic rod and a cleaning cotton to avoid the sampling tube being contaminated by other impurities. At the same time, by setting structures such as a sampling tube, a connection disk, and an internal gear ring, the sampling tube can be driven to rotate by the rotation of the connection disk to detect samples of different components. However, this device can be used for general relatively wet soils, but there are difficulties in sampling in relatively hard soils.

[0004] Based on this, in order to enable the sampler to sample normally in relatively hard soils and soils with more gravel, this design proposes an information investigation and collection device for soil general survey. Content of the Utility Model

[0005] The utility model aims to provide an information investigation and collection device for soil general survey.

[0006] An information investigation and collection device for soil general survey includes: a handle, a threaded rod, an outer cylinder, and a collection cylinder. The middle part of the handle is fixed on the threaded rod. Among them, the lower part of the threaded rod passes through the outer cylinder and is fixed to the collection cylinder. The outer cylinder has a stepped structure, and the collection cylinder has a cylindrical structure and is hollow inside.

[0007] Preferably, the outer cylinder includes: an outer cylinder housing, an inner cavity, annular spikes, a fixing plate, and fixing holes. The lower part of the outer cylinder housing is provided with annular spikes. The inner cavity is arranged inside the outer cylinder housing. Both ends of the bottom of the outer cylinder housing are fixed with fixing plates, and fixing holes are arranged on the fixing plates.

[0008] Preferably, the collection cylinder includes: a housing, a cutter head, and rollers. The housing has a cylindrical structure. The bottom of the housing is provided with a cutter head and rollers. The cutter heads are evenly distributed at the bottom of the housing. The rollers are spaced apart from the cutter heads and are evenly distributed.

[0009] Preferably, the edge side of the roller is provided with protrusions, and a rotating shaft is arranged in the middle of the roller. The rotating shaft is installed at the bottom of the housing.

[0010] The beneficial effects of the above solution are as follows:

[0011] 1. By setting the annular spikes, the present utility model can break the soil with a downward force during sampling, so as to better fix the outer cylinder housing of the sampling device. At the same time, the cutter head and roller at the bottom of the collection cylinder can rotate the collection cylinder continuously during sampling, thereby driving the cutter head and roller to rotate. When the cutter head and roller come into contact with the crushed stones, they can scrape the crushed stones, so as to crush the crushed stones bit by bit, facilitating the sampling device to sample deeper.

[0019] The present utility model will be further clearly and completely described below in conjunction with the accompanying drawings of the specification, but the protection scope of the present utility model is not limited thereto.

[0020] As Figure 1 shown, an information investigation and collection device for soil census includes: a handle 1, a threaded rod 2, an outer cylinder 3, and a collection cylinder 4. The middle part of the handle 1 is fixed on the threaded rod 2. Among them, the lower part of the threaded rod 2 passes through the outer cylinder 3 and is fixed to the collection cylinder 4. The structure of the outer cylinder 3 is stepped, and the structure of the collection cylinder 4 is cylindrical and hollow inside;

[0021] Furthermore, the handle 1 can be replaced, or an electric drill tool can be used to fix the threaded rod. When replacing the electric drill tool, the rotation speed of the collection cylinder can be increased, which is more convenient and rapid compared with manual sampling.

[0022] Specifically, the outer cylinder 3 includes: an outer cylinder housing 31, an inner cavity 32, annular spikes 33, a fixing plate 34, and fixing holes 35. An annular spike 33 is provided at the lower part of the outer cylinder housing 31. An inner cavity 32 is provided inside the outer cylinder housing 31. Fixing plates 34 are fixed at both ends of the bottom of the outer cylinder housing 31, and fixing holes 35 are provided on the fixing plates 34.

[0023] Furthermore, the fixing plate 34 provided at the edge of the outer cylinder 3 can help the sampling personnel to perform sampling better. At the same time, the sampling personnel can step on the fixing plate 34 with both feet, or sample the soil by driving an iron nail through the fixing hole 35.

[0024] Specifically, the collection cylinder 4 includes: a housing 41, a cutter head 42, and rollers 43. The structure of the housing 41 is a cylindrical structure. A cutter head 42 and rollers 43 are provided at the bottom of the housing 41. The cutter heads 42 are evenly distributed at the bottom of the housing 41, and the rollers 43 are spaced apart from the cutter heads 42 and are evenly distributed.

[0025] Furthermore, during the sampling operation, the rotation of the handle 1 drives the collection cylinder 4 to rotate. The rotation of the threaded rod 2 will generate a downward pressure. When rotating, the threaded rod 2 will squeeze the collection cylinder 4 downward continuously. Since the cutter head 42 and the rollers 43 are installed at the bottom of the housing 41, the cutter head 42 will continuously cut the soil when being squeezed downward, and the rollers 43 will also continuously squeeze the soil downward to assist in sampling the soil.

[0026] Specifically, a protrusion 431 is provided on the edge side of the roller 43, and a rotating shaft 432 is provided in the middle of the roller 43. The rotating shaft 432 is installed at the bottom of the housing 41.

[0027] Furthermore, the protrusions 431 on the rollers 43 can loosen the soil, strike the hard gravel when encountering it to improve the sampling rate, and at the same time facilitate the sampler to adapt to different soil characteristics.
