[0002] Carrot is a widely planted crop. There are two planting methods at present, one is the large ridge double row planting method, and the other is the single ridge planting method. In most areas of China, the large ridge double row planting method is adopted because of its high yield. At present, whether it is an imported harvester or a domestic harvester, its feeding port is too small, which easily causes the loss of carrots during harvesting. The feeding mechanism of this harvester effectively solves the above problem. Utility Model Content

DETAILED DESCRIPTION

[0011] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0012] It can be seen from the attached drawings: in order to ensure that the carrot tassels are completely fed into the two clamping belts 04, two introduction wheels 02 are formed with an eight-shaped opening, and the above-mentioned introduction wheels 02 are coaxially installed with a tassel-pulling plate 03 to gather the carrot tassels to the middle.

[0013] The above-mentioned driven clamping pulley 01 can swing back and forth to ensure that the radish leaves can be fed evenly with the same clamping force regardless of their density. The principle of the above-mentioned driven clamping pulley 01 swinging back and forth is: the above-mentioned driven clamping pulley 01 is connected to the rotating shaft arm 07, the above-mentioned rotating shaft arm 07 swings around the rotating shaft 06, and the spring 08 controls the swing amplitude of the above-mentioned driven clamping pulley 01, that is, the size of the clamping force; the above-mentioned spring 08 is connected to the spring support 09.

[0014] The above-mentioned driven clamping pulley 01 , the rotating shaft arm 07 , the above-mentioned rotating shaft 06 , the above-mentioned spring 08 and spring support 09 , and the above-mentioned introduction wheel 02 are all installed on the inlet housing 10 through the pulley vertical shaft 05 .

[0015] The inlet housing 10 is connected to the telescopic body 17 through the safety bolt 11. The telescopic body 17 is installed in the frame main beam 18 and can move forward and backward. The telescopic body 17 is connected with a right tie rod seat 12, which is connected to one end of the right-hand tie rod 13. The frame main beam 18 is connected to the left tie rod seat 16, which is connected to one end of the left-hand tie rod 15. The right-hand tie rod 13 and the middle end of the left-hand tie rod 15 are connected by the adjustment nut 14. Rotate the adjustment nut 14, the left-hand tie rod 15 and the right-hand tie rod 13 pull the telescopic body 17 inward, so that the clamping belt 04 can be loosened. Reversely rotate the adjustment nut 14, the left-hand tie rod 15 and the right-hand tie rod 13 push the telescopic body 17 outward, so that the clamping belt 04 can be tightened.

[0016] The working process of this feeding mechanism is as follows:

[0017] The carrot harvester moves forward, and the carrot tassels of two rows are gathered to the middle by the figure-eight entrance formed by the two introduction wheels 02, and enter the clamping opening formed by the two driven clamping belt wheels 01, clamping the carrot tassels and sending them to the rear. The tightness of the clamping belt 04 can be adjusted by rotating the adjustment nut 14.

[0018] If the front end of the feeding port suddenly touches the ground, generating a large impact force, the safety bolt 11 will automatically break off to protect the entire machine from being damaged.
