Description

Technical Field

[0001] The utility model belongs to the technical field of samplers and relates to an auxiliary lower rod device for a deep sampler. Background Art

[0002] In order to check the quality of each layer of grain in the grain pile, a sampling machine is generally used to extract grain from each layer of the grain pile by insertion, and then the grain extracted by the sampling machine is checked to achieve the purpose of checking the quality of each layer of grain in the grain pile.

[0003] An existing sampling machine, such as the applicant's prior patent application and a feeding device of a sampling machine disclosed in Chinese patent literature [patent number: 201720808735.6; application publication number: CN206906039U], includes a base plate, a vertical sampling rod is provided on the front of the base plate, and a motor is provided on the back of the base plate. A left belt is mounted on the two pulleys on the left side of the sampling rod, and a right belt is mounted on the two pulleys on the right side of the sampling rod. The rubber blocks on the outer peripheral surface of the left belt and the rubber blocks on the outer peripheral surface of the right belt cooperate to clamp the sampling rod. The motor drives the two pulleys located on the upper or lower side of the base plate through a driving device, so that the left belt and the right belt rotate synchronously and in opposite directions.

[0004] The feeding device of the sampling machine with this structure can make the sampling rod better inserted into the grain pile, and after the lower end of the sampling rod touches the ground, the rubber block and the sampling rod are in a slipping state, which avoids the lower end of the sampling rod from bending and being damaged. When in use, this feeding device is placed on the surface of the grain pile, but because the grain pile is formed by piling up grains, the grain pile is not fixed. During operation, the feeding device has a tilting problem and poor stability, causing the sampling rod to be inserted obliquely into the grain pile, so that the depth of the grain reflected in the sampling rod is different from the actual depth of the grain, which causes the operator to misjudge the quality of each layer of grain and reduce the quality of grain sampling. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to propose an auxiliary lowering rod device for a deep-layer sampler, so as to solve the technical problem of how to improve the stability of the sampler.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an auxiliary lowering rod device for a deep sampler, including a feeding structure for driving the sampling rod to move, the feeding structure including a mounting frame, characterized in that the auxiliary lowering rod device also includes a bottom frame in the shape of a long strip frame, both ends of the bottom frame have at least two sheet-shaped positioning plates protruding downward, and the middle of the bottom frame has two mounting frames protruding upward, the mounting frame is fixedly connected to the two mounting frames, so that the feeding structure is arranged between the two mounting frames.

[0007] During use, the bottom frame is placed on the grain pile, and the positioning plate is embedded in the grain pile. Since the positioning plate is in the form of a sheet, the embedding of the positioning plate is labor-saving, making it easy to position the bottom frame, so that the feeding structure installed on the bottom frame will not have the problem of deflection, thereby improving the stability of the sampler, ensuring that the sampling rod is inserted into the grain pile in the set direction, and improving the quality of grain sampling. The bottom frame is in the shape of a long strip, which is conducive to the ventilation of the grain pile and avoids problems such as mold caused by the auxiliary lower rod device being placed on the grain pile for too long. The bottom frame is in the shape of a long strip, and the installation frame is also in the shape of a frame, so that the weight of the auxiliary lower rod device will not be too heavy, making the auxiliary lower rod device easy to move. The feeding structure is installed on the bottom frame, and the feeding structure provides sufficient gravity so that the bottom frame can be better positioned in the grain pile, so that the sampling rod will not have the problem of offset when the feeding structure is working.

[0008] In the aforementioned auxiliary lowering rod device for a deep-layer sampler, the bottom frame includes two long bars on either side, each end of which has a plurality of downwardly protruding positioning rods. The positioning plate is arranged along the length of the long bars, the inner side of the positioning plate is fitted and fixedly connected to all the positioning rods, and the top of the positioning plate is fixedly connected to the ends of the long bars. This structure provides the positioning plate with sufficient strength, ensuring that the positioning plate can be well embedded in the grain pile, improving the stability of the sampler and enhancing the quality of grain sampling.

[0009] In the above-mentioned auxiliary rod lowering device for a deep-layer sampler, the long rod is a telescopic rod. The length of the long rod can be adjusted according to actual needs, so that the auxiliary rod lowering device can be applicable to different occasions.

[0010] In the aforementioned auxiliary rod lowering device for a deep-layer sampler, the positioning rod is a hollow tube with a square cross-section. The bottom of the positioning rod has an opening, which is arranged obliquely downward along the positioning rod toward the positioning plate. When inserted, the grain enters the positioning rod, which strengthens the positioning plate and reduces the effort required to insert the positioning plate into the grain pile.

[0011] In the above-mentioned auxiliary lower rod device for a deep sampler, all the positioning plates are located in the same plane or are parallel to each other.

[0012] In the above-mentioned auxiliary rod lowering device for a deep-layer sampler, the bottom of the positioning plate is in a sharp angle shape with a lower middle and higher sides, so that the positioning plate can be better inserted into the grain pile, thereby improving the stability of the sampler and the quality of grain sampling.

[0013] In the aforementioned auxiliary rod lowering device for a deep-layer sampler, the feeding structure further includes two pulleys, at least one pair of upper guide wheels, and at least one pair of lower guide wheels. The upper guide wheels are located directly above the pulleys, and the lower guide wheels are located directly below the pulleys. A plurality of rubber blocks are fixedly connected to the outer side walls of the two pulleys. The upper guide wheels and the lower guide wheels are used to guide the sampling rod. The two pulleys rotate synchronously and in opposite directions to drive the sampling rod to move through the rubber blocks. The sampling rod is embedded between the upper guide wheel, the lower guide wheel, and the rubber blocks. The upper guide wheel and the lower guide wheel guide the sampling rod. The rubber blocks clamp the sampling rod to drive the sampling rod to move, replacing manual insertion, making the insertion of the sampling rod labor-saving.

[0014] In the aforementioned auxiliary rod lowering device for a deep-layer sampler, the feeding structure further includes an elastic compression member, which is fixedly connected to the mounting bracket or the mounting frame. The compression head of the elastic compression member can always press against the sampling rod. The elastic compression member is prior art, and its specific structure is not described in detail here. The elastic compression member can effectively press the sampling rod, ensuring that the sampling rod is always inserted into the grain pile in the set direction.

[0015] Compared with the prior art, the auxiliary lowering rod device for a deep-layer sampler provided by the utility model has the following advantages:

[0016] 1. This sampler is equipped with a bottom frame and a positioning plate so that the feeding structure can be stably set on the grain pile, thereby improving the stability of the sampler and the quality of grain sampling.

[0017] 2. The positioning plate of this sampler is in sheet shape, which saves effort when embedding the positioning plate into the grain pile, making the installation and positioning of the auxiliary lower rod device convenient. BRIEF DESCRIPTION OF THE DRAWINGS
