[0002] As the saying goes, "Food is the paramount necessity of the people". Grain is the foundation of social life. Once the grain reserve is insufficient, it will cause great social unrest and chaos. Therefore, the importance of grain is self-evident, and national food security is of utmost importance.

[0003] Grain mainly consists of wheat, beans, coarse grains, rice, etc. After the grain is harvested, in order to extend the storage period of the grain and prevent it from mildewing and deteriorating, it needs to be stored in a grain warehouse. The bag-shaped grain storage cellar in the Yangshao Culture period of China is the prototype of the grain warehouse. By the Zhou Dynasty and the Spring and Autumn Period and the Warring States Period, relatively regular grain warehouses had emerged. In modern times, with the development and progress of technology, grain storage warehouses have developed towards automation and intelligence. The grain silo warehouse is a common grain storage building, with a cylindrical structure, usually made of reinforced concrete. Its advantages are strong structure, strong wind and earthquake resistance, and can store a large amount of grain for a long time.

[0004] When using a grain silo warehouse to store grain, in order to facilitate timely understanding of the grain storage status, it is often necessary to sample and detect the grain deep in the silo warehouse. However, due to the generally high height of the silo warehouse, sampling is relatively inconvenient, and at the same time, it is not easy to control the sampling depth, making it difficult to complete accurate, convenient, and rapid sampling operations.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Refer to Figure 1 And Figure 2, A deep grain sampling device for a grain silo warehouse, comprising a sampling box 1 and a remote control 11. The sampling box 1 is fixedly installed on the inner wall of the warehouse wall 3 through a side-mounted positioning plate 2. A single-chip microcomputer 13 is arranged inside the sampling box 1. The single-chip microcomputer 13 is electrically connected to a signal antenna 5 arranged outside the sampling box 1 through a wireless communication module 12. The signal antenna 5 is connected to the remote control 11 through a wireless signal. A terminal block 4 is electrically connected to the side of the single-chip microcomputer 13. The single-chip microcomputer 13 is respectively electrically connected to an air pump 14 and a motor gearbox 15, both of which adopt stepping motors. The motor gearbox 15 is drivingly connected to a ball gear cylinder 17 through a driving gear 16. A limit baffle 18 is arranged above and below the ball gear cylinder 17. The inside of the ball gear cylinder 17 is in rolling connection with a hollow threaded rod 9 through balls. A rotating sealing ring 8 is arranged at the top of the hollow threaded rod 9. The rotating sealing ring 8 is connected to the air pump 14 through a diversion pipe 7. A sample discharge pipe 6 is arranged at the bottom of the air pump 14. A hollow sampling rod 10 is arranged at the bottom of the hollow threaded rod 9. Installation holes 19 for the hollow threaded rod 9 and the hollow sampling rod 10 to pass through are formed on both the upper shell and the lower shell of the sampling box 1.

[0020] Refer to Figure 2 , The limit baffle 18 is fixedly connected to the side-mounted positioning plate 2. Such a setting can utilize the limit baffle 18 to provide a fixed limit function for the ball gear cylinder 17. When the ball gear cylinder 17 rotates, the reaction force can push the hollow threaded rod 9 to rotate, thereby driving the hollow threaded rod 9 to move up or down.

[0021] Refer to Figure 1 and Figure 2 , The rotating sealing ring 8 is in rotating and sealing connection with the hollow threaded rod 9, and the rotating sealing ring 8 is fixedly and sealingly connected to the diversion pipe 7. Such a setting can ensure that when the hollow threaded rod 9 rotates, the rotating sealing ring 8 and the diversion pipe 7 are still in a sealed state, avoiding air leakage.

[0022] Refer to Figure 1 and Figure 2 , The hollow threaded rod 9 is made of a soft rubber hose. Such a setting is convenient for the soft rubber hose with a certain elasticity to move up and down along with the hollow threaded rod 9 when the hollow threaded rod 9 moves up and down, and it will not get stuck or break.

[0023] Refer to Figure 3, the remote controller 11 includes a circuit board 1101. On the top of the circuit board 1101, there is a telescopic antenna 1103 connected to the signal antenna 5 through wireless signals. On the front of the circuit board 1101, there is a display screen 1102 electrically connected. Below the display screen 1102, there is a numeric keypad 1104. Below the numeric keypad 1104, there are a sampling depth setting button 1105 and a sampling start button 1106. On the side of the sampling start button 1106, there is a working indicator light 1107. Such a setting facilitates the operator to hold the remote controller 11. By pressing the sampling depth setting button 1105, the sampling depth input function can be enabled. Then, the operator can use the numeric keypad 1104 to set the sampling depth, which is displayed in real time through the display screen 1102. After setting the depth, the sampling operation can be started by pressing the sampling start button 1106.

[0024] Working principle: When using this device, first, the sampling box 1 is fixedly installed on the inner wall of the warehouse wall 3 through the side-mounted positioning plate 2, so as to fix the sampling box 1 inside the grain silo warehouse. The power grid of the grain silo warehouse is connected to this device through the terminal 4 to supply power to this device. When deep grain sampling operation is required, the operator holds the remote controller 11 and inputs the sampling depth information. After the remote controller 11 processes the information, it is converted into a wireless signal and transmitted. The signal antenna 5 receives the wireless signal and feeds it back to the wireless communication module 12 for processing. Then, the work instruction book is input into the single-chip microcomputer 13. The single-chip microcomputer 13 controls the motor drive box 15 to start. The motor drive box 15 drives the ball gear cylinder 17 to rotate through the transmission gear 16. The relative rotation of the ball gear cylinder 17 and the hollow threaded rod 9 drives the hollow threaded rod 9 to move downward. The hollow threaded rod 9 drives the hollow sampling rod 10 to move downward. At the same time, the single-chip microcomputer 13 controls the air pump 14 to start. The air is pumped into the hollow threaded rod 9 through the sample discharge pipe 6 and then pressurized and pumped into the hollow threaded rod 9 through the diversion pipe 7, and finally discharged from the bottom of the hollow sampling rod 10 to form a high-pressure air flow to blow away the surrounding grains, preventing the surface grains from entering the hollow sampling rod 10 and affecting the sampling result. Until the bottom of the hollow sampling rod 10 reaches the specified depth, at this time, the single-chip microcomputer 13 controls the stepping motor in the air pump 14 to start in the reverse direction. The air pump 14 pumps out the air in the hollow sampling rod 10, the hollow threaded rod 9 and the diversion pipe 7 and discharges it from the sample discharge pipe 6, forming a low pressure in the hollow sampling rod 10, so as to suck in the grains and finally discharge them from the sample discharge pipe 6 to complete the sampling operation.

For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the component relationship and technical effect, or it can be an integral connection or a partial connection. In the case of this example, for those of ordinary skill in the art, the specific meanings of the above terms in this utility model or the utility model can be understood according to specific circumstances. In this utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings.
