Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product sampling, in particular to a sampler used in agricultural production. Background Art

[0002] A corn cob sampler is a tool for collecting corn cob samples, which is usually composed of a sampling barrel, a drill bit, a sawtooth and other parts. Its working principle is to rotate or press the sampler, use the drill bit to cut into the corn cob pile, collect the tissue sample of the corn cob into the sampling barrel, and thus obtain a representative corn cob sample. When using the existing corn cob sampler for sampling, when the drill bit is inserted into the corn cob pile, the drill bit is easily inserted directly into the corn cob, resulting in obstruction of the insertion of the sampling barrel. The process of inserting the sampler is laborious for the user, and the sampler needs to be repeatedly pulled out and inserted, which reduces the sampling efficiency.

[0003] Furthermore, since the serrations of the existing corn cob sampler are exposed, when the sampler is inserted into a pile of corn cobs, friction occurs between the serrations and the corn cobs, making it difficult for the user to insert the sampler. At the same time, the exposed serrations can easily scrape corn kernels on the moving path of the sampling barrel into the sampling barrel, resulting in a low reference value of the extracted corn sample and reducing the effect of fixed-point sampling. Utility Model Content

[0004] In order to overcome the shortcomings of the existing corn cob sampler in which the drill bit is easily blocked during the sampling process, the user needs to repeatedly pull out and insert the sampler, which reduces the sampling efficiency. At the same time, the exposed serrations are easy to scrape corn kernels on the moving path of the sampling barrel into the sampling barrel, reducing the effect of fixed-point sampling. The utility model provides a sampler for agricultural production.

[0005] The technical solution of the utility model is: a sampler for agricultural production, comprising a sampling barrel; two handles are provided on the sampling barrel; a sampling port is provided on the sampling barrel; and the sampler also comprises saw teeth, a storage assembly, a drill bit and an elastic member; two saw teeth for scraping off corn kernels are rotatably connected to the sampling port of the sampling barrel; each saw tooth is provided with a plurality of tooth tips; two limiting portions for limiting the saw teeth are provided on the sampling barrel; a storage assembly for storing the saw teeth is provided on the sampling barrel; a movable cavity is provided on the sampling barrel; a drill bit is rotatably connected in the movable cavity for facilitating the insertion of the sampling barrel into a pile of corn cobs; a plurality of elastic members are provided in the movable cavity; and each elastic member is connected to the drill bit.

[0006] Furthermore, the storage assembly includes a movable rod and a cover plate; the movable rod is slidably connected to the sampling tube; the cover plate for storing the saw teeth is fixedly connected to the movable rod; and the cover plate is attached to the outer side of the sampling tube.

[0007] Furthermore, two guide parts are provided at the front end of the cover plate.

[0008] Furthermore, two protrusions are provided on the lower side of the cover plate.

[0009] Furthermore, the tooth tip on each saw tooth is arranged to be inclined toward the side away from the guide portion.

[0010] Furthermore, the front end of the drill bit is configured as an arc surface.

[0011] Furthermore, it also includes an anti-skid pad; each handle of the sampling tube is fixed with an anti-skid pad to reduce slipping; the anti-skid pad is made of rubber.

[0012] Furthermore, each anti-slip pad is provided with a plurality of rubber protrusions.

[0013] Beneficial effects: The utility model realizes that the front end of the drill bit is set to a circular arc surface, which prevents the front end of the drill bit from being directly inserted into the corn cob. At the same time, the drill bit can be guided by the corn cob to perform adaptive steering, which prevents the insertion of the sampling tube from being blocked, and is conducive to conveniently inserting the sampling tube into the corn cob pile;

[0014] The cover plate guides and stores the saw teeth, preventing the exposed saw teeth from contacting and rubbing against the accumulated corn cobs, which would make the insertion of the sampling tube difficult. At the same time, the saw teeth are prevented from scraping corn kernels on the moving path of the sampling tube into the sampling port, thus avoiding the low reference value of the corn samples taken out, thus ensuring the effect of fixed-point sampling.

[0015] By setting the tooth tips on the saw teeth in an inclined state, it is convenient for the guide part to squeeze the saw teeth toward the middle of the sampling tube, thereby ensuring the storage effect of the saw teeth;

[0016] The raised portion contacts the lower portion of the tooth tip of the saw tooth, so that the force point of the tooth tip of the saw tooth is transferred from the lower side of the cover plate to the raised portion, preventing the tooth tip of the saw tooth and the lower side of the cover plate from wearing each other, thereby extending the service life of the sampler.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-Figure 7 As shown, a sampler for agricultural production includes a sampling barrel 1; the sampling barrel 1 is provided with two handles; the sampling barrel 1 is provided with a sampling port 1001;

[0028] It also includes saw teeth 2, a storage component, a drill bit 3 and an elastic member 4; the sampling port 1001 of the sampling barrel 1 is rotatably connected to two symmetrically arranged saw teeth 2 through a torsion spring; each saw tooth 2 is provided with a number of tooth tips; the sampling barrel 1 is provided with two symmetrically arranged limiting parts 1002; the sampling barrel 1 is provided with a storage component; the sampling barrel 1 is provided with a movable cavity 1003; the drill bit 3 is rotatably connected to the movable cavity 1003; the movable cavity 1003 is provided with a number of elastic members 4 in a ring array, and the elastic member 4 is a spring; each elastic member 4 is connected to the drill bit 3.

[0029] The storage assembly includes a movable rod 101 and a cover plate 102 ; the movable rod 101 is slidably connected to the sampling tube 1 ; the cover plate 102 is fixed to the movable rod 101 ; and the cover plate 102 is attached to the outer side of the sampling tube 1 .

[0030] Two symmetrically arranged guide portions 10201 are provided at the front end of the cover plate 102 .

[0031] Two symmetrically arranged protrusions 10202 are provided on the lower side of the cover plate 102 .

[0032] The tooth tip on each saw tooth 2 is arranged to be inclined toward the side away from the guide portion 10201, so that the guide portion 10201 can squeeze the saw tooth 2 toward the middle of the sampling tube 1, thereby ensuring the storage effect of the saw tooth 2.

[0033] The front end of the drill bit 3 is configured as an arc surface. When the front end of the drill bit 3 contacts the corn cob, it can be guided by the corn cob to avoid it, thereby preventing the front end of the drill bit 3 from being inserted into the corn cob.

[0034] Before sampling corn from a corncob pile, the user pushes the movable rod 101 forward, causing the movable rod 101 to drive the cover plate 102 to move toward the sawtooth 2. The guide portion 10201 at the front end of the cover plate 102 contacts the rear side of the sawtooth 2, and the sawtooth 2 is squeezed and rotated toward the sampling port 1001, while compressing the torsion spring between the sawtooth 2 and the sampling tube 1. Figure 2 As shown, the cover plate 102 is completely covered to the upper side of the sampling port 1001 to complete the storage of the serrations 2. When the sampling tube 1 is subsequently inserted into the corn cob pile, the exposed serrations 2 are prevented from contacting and rubbing with the stacked corn cobs, which makes the insertion of the sampling tube 1 difficult. At the same time, the serrations 2 are prevented from scraping the corn kernels on the moving path of the sampling tube 1 into the sampling port 1001, thereby avoiding the low reference value of the taken corn samples and ensuring the effect of fixed-point sampling.

[0035] When the saw teeth 2 are stored, the user aligns the drill bit 3 with the part of the corn cob pile that needs to be sampled, and then inserts the sampling tube 1 into the corn cob pile. During the process of inserting the sampling tube 1, when the drill bit 3 contacts the corn cob, the front end of the drill bit 3 is set to an arc surface to prevent the front end of the drill bit 3 from directly inserting into the corn cob. At the same time, the drill bit 3 can be guided by the corn cob to perform adaptive steering, so that the drill bit 3 rotates in the active cavity 1003, and at the same time stretches or compresses the corresponding elastic member 4 to prevent the insertion process of the sampling tube 1 from being obstructed, which is conducive to conveniently inserting the sampling tube 1 into the corn cob pile.

[0036] After the sampling tube 1 is inserted into the corn cob pile, the user pulls the movable rod 101 backwards, so that the movable rod 101 drives the cover plate 102 to move backwards from the upper side of the sampling port 1001, releasing the limit of the cover plate 102 on the saw teeth 2, and the saw teeth 2 rebound to their original position under the elastic force of the torsion spring. Figure 3 The sampling tube 1 is in the expanded state shown, and then the user grips the handle and rotates the sampling tube 1, so that the sampling tube 1 drives the saw teeth 2 to rub against the corn cob, thereby scraping the corn kernels on the corn cob into the sampling port 1001. During this process, the saw teeth 2 are limited by the limiting portion 1002 to prevent the saw teeth 2 from rotating toward the outside of the sampling tube 1, thereby ensuring the scraping effect of the saw teeth 2 on the corn cob. When the sampling is completed, the user can directly pull the sampling tube 1 out of the corn cob pile to complete the sampling of the corn.

[0037] 2, so that the tooth tip of the saw tooth 2 is prevented from being scratched by the user.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1 and Figure 7 As shown, an anti-skid pad 201 is also included; each handle of the sampling tube 1 is fixed with an anti-skid pad 201; the anti-skid pad 201 is made of rubber.

[0040] Each anti-slip pad 201 is provided with a plurality of rubber protrusions, which are helpful to enhance the anti-slip effect.

[0041] When the user inserts the sampling barrel 1 into the corn cob pile, and in the subsequent process of rotating the sampling barrel 1, the friction between the user's hand and the handle of the sampling barrel 1 is increased by the anti-slip pad 201 on the handle of the sampling barrel 1 and the rubber protrusion on the anti-slip pad 201, preventing the user from slipping when pushing and rotating the sampling barrel 1 with force, and avoiding the user's inability to accurately control the direction and depth of the sampling barrel 1 during operation, resulting in the sampling position not being consistent with the expectation, thereby ensuring the reference value of the sample taken out and improving the user's grip on the handle of the sampling barrel 1.

[0042] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
