Referring to fig. 3, guide rollers 14 are installed under the frame 6 in order to keep stability when rotating.
In order to feed and hold the beet entering the notch in the sampling cylinder and unload the beet, the beet in the sampling cylinder can be unloaded, the sampling cylinder 11 is a hollow thin-wall round tube, the lower opening is provided with a wedge-shaped notch for the beet to enter, when the sampling cylinder 11 rotates, the beet can enter the sampling cylinder 11 from the notch, two helical blades 18 are arranged in the sampling cylinder 11, the beet entering from the notch is guided into the sampling cylinder 11 by the helical blades 18 and is held in the sampling cylinder 11, when the beet sample in the sampling cylinder 11 needs to be unloaded, the helical blades 18 are moved downwards to leave the lower opening of the sampling cylinder 11, and the beet in the sampling cylinder 11 is unloaded under the action of gravity.
Referring to fig. 4, in order to keep the helical blade stable and not deformed during operation and unloading, a guide groove block 16 is fixed on the inner vertical edge of the lower opening of the sampling tube 11, a guide groove is formed on the guide groove block 16, an upright plate 20 is arranged at the outer edge of the helical blade 18, one edge of the upright plate 20 is inserted into the guide groove of the guide groove block 16, and the other edge is an arc-shaped recess to form the front edge of a feeding notch, and the upright plate plays a guiding role when the helical blade 18 moves downwards to unload materials.
In order to prevent the pull rod from being deformed by a transverse force and limit the transverse movement of the pull rod, limit plates 15 for limiting the transverse movement of the pull rod 17 are arranged on the inner wall of the sampling tube 11, and each pull rod 17 is correspondingly arranged on one limit plate 15.
The outer diameter of the hollow shaft is in a stepped shape with a thick upper part and a thin lower part, the shell of the speed reducer needs to be disassembled when the hollow shaft is installed, so that the downward force generated by the sampling cylinder is born by the output shaft of the speed reducer, and the upward force is born by the bearing of the upper shell of the speed reducer.
The working principle of the utility model is as follows: after the beet car is parked in the sampling parking space, the mobile cart 12 is driven by the motor 13 to move on the external support beam track to move the sampling device from a position above the discharge hopper to a selected sampling position above the beet car. The shaft of the lifting oil cylinder 1 extends out to drive the sampling cylinder 11 to move downwards, and meanwhile, the speed reducing motor 9 is started to drive the sampling cylinder 11, the helical blade 18 and the like to rotate together and vertically insert into the beet. When the lower opening of the sampling tube 11 contacts the beets on the vehicle, the complete beets root pieces are eaten from the wedge-shaped notch and are guided into the sampling tube 11 by the spiral blade 18. With the continuous downward movement of the sampling cylinder 11, the number of the eaten beets is increased, when the sampling cylinder 11 reaches a specified depth, the shaft of the lifting oil cylinder 1 retracts to drive the sampling cylinder 11 to move upwards, when the sampling cylinder 11 reaches an upper limit position, the speed reducer 9 stops, and at the moment, the sampling cylinder 11 stops rotating. The locomotive starts, sends sampling device to the discharge hopper top, and at this moment, the axle of unloading hydro-cylinder 5 stretches out, drives two helical blade 18 and moves down, leaves sampling tube 11 end opening, and the beet in the sampling tube 11 falls into in the discharge hopper under the action of gravity. After the unloading is finished, the shaft of the unloading oil cylinder 5 retracts, and the helical blade 18 returns to the lower opening of the sampling cylinder 11. One sampling cycle is completed. Because the sampling cylinder is rotated to eat complete beet root blocks from the lower wedge-shaped notch, no force for crushing the beet is generated, and the beet crushing rate is very low in the sampling process.
When the sampling cylinder 11 rotates, the helical blade 18, the pull rod 17 and the connecting disc 10 also rotate along with the sampling cylinder 11, and the connecting rod 8, the unloading cylinder shaft and the piston also can rotate but are not necessarily synchronous with the sampling cylinder 11.
