Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] This utility model provides a multifunctional sampling device for grain quality testing. Please refer to [link / reference]. Figure 1-4 The sampling vehicle includes a first electric push rod 9, on which a sampling mechanism is mounted; the sampling mechanism is driven to extend into any position in the grain pile by extending and retracting the first electric push rod 9.

[0024] The sampling vehicle includes a bottom support plate 1, with casters 2 fixedly installed on the bottom of the bottom support plate 1, and a second electric push rod 8 installed on the bottom support plate 1. The first electric push rod 9 is fixedly installed on the second electric push rod 8.

[0025] The bottom support plate 1 is equipped with a handle 3 on its top. Specifically, a support connecting seat is welded to the top of the bottom support plate 1, and the bottom of the handle 3 is inserted into the support connecting seat. Internal threaded holes are opened at corresponding positions between the support connecting seat and the handle 3. The support connecting seat and the handle 3 are fixed together by bolts, and a protective sleeve is fitted at the end of the handle 3.

[0026] The top of the second electric push rod 8 is welded with a support plate 7, and the outer wall of the support plate 7 is welded with a bridging rod 6. The other end of the bridging rod 6 is welded with a collar 5. The collar 5 is sleeved on the support column 4, and the collar 5 and the support column 4 are slidably connected. The bottom of the support column 4 is welded to the bottom support plate 1. Thus, when the first electric push rod 9 drives the sampling mechanism to extend into the grain pile, the support column 4 supports the reaction force, thereby preventing the second electric push rod 8 from bending under the reaction force. The second electric push rod 8 is used to drive the sampling mechanism to rise and fall, thereby sampling the internal areas of the grain field at different heights.

[0027] The sampling mechanism includes a motor housing 14 bolted to a first electric push rod 9. A servo motor 18 is installed inside the motor housing 14. The output shaft of the servo motor 18 is connected to a third electric push rod 17 via a coupling. A helical rod 16 is bolted to the top of the third electric push rod 17. Specifically, a first mounting plate is welded to the bottom of the helical rod 16, and a second mounting plate is welded to the top of the third electric push rod 17. The first and second mounting plates are fixed together by bolts. A sampling tube 13 is welded to the top of the motor housing 14, and a solenoid valve 12 is bolted to the top of the sampling tube 13. The wires of valve 12, third electric push rod 17, and servo motor 18 all pass through wire sleeve 10. The switches controlling solenoid valve 12, third electric push rod 17, servo motor 18, second electric push rod 8, and first electric push rod 9 are all mounted on switch panel. The switch panel can be mounted on handle 3 for operation. One end of wire sleeve 10 is fixedly connected to solenoid valve 12, and the bottom of wire sleeve 10 is mounted on wire sleeve 10 by clamp 15. A drag-reducing plate 11 is welded to the end of first electric push rod 9. With the presence of drag-reducing plate 11, the resistance of the sampling mechanism extending into the grain pile can be reduced, thus allowing it to extend into the grain pile more smoothly.

[0028] The sampling tube 13 has a flange at its top end, and the flange at the top of the sampling tube 13 is fixed to the flange at the bottom of the solenoid valve 12 by bolts.

[0029] In practical use, the hand-held handle 3 is used to move the drive device to the grain pile. The second electric push rod 8 drives the sampling mechanism to rise and fall to the required height. The first electric push rod 9 drives the sampling mechanism to extend into the grain pile. When the sampling depth is reached, the solenoid valve 12 and servo motor 18 are opened. The third electric push rod 17 drives the screw rod 16 to rise until it contacts the grain. The servo motor 18 drives the screw rod 16 to rotate, allowing the grain to enter the solenoid valve 12 and the sampling tube 13 to complete the sampling. Then the servo motor 18 is turned off. The third electric push rod 17 drives the screw rod 16 to reset, closes the solenoid valve 12, and the first electric push rod 9 retracts, driving the sampling mechanism to move out of the grain pile.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
