Description
Technical Field
The invention relates to a novel soil sampler.
Background
The basic resource of agricultural development is land resource, and in order to promote the agricultural rapid development, scientists continuously carry out comprehensive deep systematic research to soil, and in the research process, the first work is the collection to the soil sample, and sample collection work has been comparatively heavy work all the time, and the sampling instrument is comparatively laggard behind, consumes a large amount of manpowers. When a traditional soil drill is used for sampling, the problem of floating soil pollution often occurs; after collection, the sample is difficult to take out, and the sample bag is often punctured, so that the sample is scattered or the accident that an operator is stabbed is caused; and the labor intensity of collecting samples by using the traditional tool is high, the working efficiency is low, and the high-efficiency development of research is not facilitated.
Disclosure of Invention
The invention aims to provide a novel soil sampler which is specially designed for testing, reduces the labor intensity of soil sample collection, improves the working efficiency, and solves the problem that a sample bag is poked to be broken and the sample is scattered or an operator is poked to be hurt when a traditional soil drill is used for sampling; and the problem that the conventional soil drill enters the floating soil from the opening end to pollute the sample when taking down the soil on the layer can be well avoided.
The technical scheme of the invention is as follows:
the invention relates to a novel soil sampler, which is characterized in that a drill bit is designed into a cylinder shape and is called a drill bit cylinder, the downward opening end of the drill bit cylinder is an inner flat and outer inclined cutting edge, the outer wall of the drill bit cylinder is provided with scales, exhaust round holes which are inclined downwards from inside to outside are uniformly distributed on the cylinder wall of the drill bit cylinder in a scale interval of 40cm-50cm, a piston which can be pushed up and down is arranged in the drill bit cylinder, the top of the upper surface of the drill bit cylinder is connected with a drill rod, the drill rod is designed into a hollow upper solid structure at the lower part, the drill rod and the drill bit are detachably or fixedly connected, a hydraulic oil cylinder is arranged in a hollow cavity part in the drill rod, a telescopic rod of a hydraulic push arm is connected with the piston in the drill bit to push the; and a hydraulic pump connecting port is reserved on the drill rod cylinder.
Furthermore, the upper end of the drill rod is provided with two sections, and the two sections are detachably connected, so that the extension rod is conveniently additionally arranged between the two sections to realize the extension of the drill rod.
The invention has the beneficial effects that: the invention is specially designed for soil testing and sampling, the piston is arranged in the drill bit, the hydraulic oil cylinder is arranged in the drill rod connected with the drill bit, the soil sample can be taken out through hydraulic pushing, the labor intensity of agricultural scientific research work is reduced, and the working efficiency is improved. And meanwhile, the accidents that samples are scattered when the traditional earth auger is used for breaking a sample bag or stabbing an operator are solved. The drill bit is cylindric design, and the sample is unrestrained when can avoiding hydraulic pressure work to and the soil slick pollutes the scheduling problem when gathering the sample. The invention has the advantages of convenient disassembly and assembly, convenient use during outgoing tests, avoidance of pollution of soil samples, improvement of the accuracy of experimental data, realization of semi-mechanization of soil sampling, and great significance for mechanization realization of future soil detection and research.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a rear view of fig. 1 of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in attached figures 1 and 2, a drill bit 1 of the novel soil sampler is a cylinder with the length of about 50cm, the open end of the cylinder is an inner flat and outer inclined cutting edge 1-1, the outer wall of the cylinder is provided with a shade scale, the minimum scale is 5cm, and the scale is filled with red; in a scale interval of 40cm-50cm, an exhaust round hole 1-2 which is inclined downwards from outside to inside is arranged. A piston 2 capable of being smoothly pushed up and down is arranged in the drill bit (the area of the piston is slightly smaller than the cross sectional area of an inner cavity of the drill bit), a drill rod 3 connected with the top of the drill bit is of a hollow structure at the lower part and is in detachable connection with the drill bit 1. A hydraulic oil cylinder 4 is arranged in the hollow cavity part in the drill rod 3, a hydraulic push arm 5 is connected with the piston 2 in the drill bit 1 and used for pushing the piston 2, and the length of the hydraulic push arm 5 is preferably that the farthest end of the piston 2 reaches the opening of the drill bit 1 but not extends out. A connecting opening 6 for connecting the hydraulic pump with the hydraulic oil cylinder is reserved on the drill rod 3. The effective length (length after connection) of the drill rod 3 is generally set to about 100 cm. The upper end of the drill rod 3 is provided with two sections, and the two sections are detachably connected, so that the drill rod can be lengthened by additionally arranging a lengthening rod between the two sections.
