The cutting rod device is integrally fixed by matching the installation of the lug plates on the bottom surface of the transportation bracket. In the whole garlic conveying process, the garlic stems are cut off by the stem cutting device, and the garlic heads are left.

Furthermore, a connecting rod is fixedly arranged on the driving belt wheel, a mud scraper is arranged at the tail end of the connecting rod, and the connecting rod is connected with the mud scraper through a bolt.

Further, the tension device is arranged in the following form: the middle part of the driven belt wheel is in a shaft body form penetrating through the base, a push plate is sleeved on the shaft body, and the push plate is a bending plate. The push plate is fixedly provided with a bolt, a limiting plate is arranged on the surface of the base corresponding to the direction of the bolt, a through hole is formed in the limiting plate, the bolt penetrates through the through hole, an adjusting nut is screwed at the tail end of the bolt, and the bolt is pushed to the push plate by rotating the nut and adjusting the position of the bolt, so that the middle shaft of the driven belt wheel is pushed, and the driven belt wheel is pushed to be tensioned.

Furthermore, the two cutting edges are respectively a straight cutting edge and a sawtooth cutting edge to prevent the garlic stem from slipping.

The invention has the beneficial effects that: the garlic stem cutting machine is simple in structure, convenient to use, low in manufacturing cost and easy to maintain, and stem cutting work of garlic is achieved through the simple structure. Compared with the prior art, the garlic stem channel of the device is designed to be communicated, and the mud scraper arranged in the belt ensures that the device cannot be blocked when in operation; moreover, the equipment is accurately positioned and clamped by the belt, so that garlic cannot be damaged; meanwhile, due to the arrangement of the universal joint coupler and the design of the lug plate mounting groove, the tool setting is more convenient, quicker and more accurate.

Detailed Description

Referring to fig. 1, 2, 3 and 4, the fixed-length garlic stem cutting device of the garlic harvester according to the present invention comprises a stem cutting device and a bracket part;

the rod cutting device comprises a base 3, wherein the base 3 is integrally in a flat plate shape and is a main body bearing part of the rod cutting device. A pair of driven belt wheels 1 and a pair of driving belt wheels 5 are oppositely arranged on the base 3, and the belt wheels are in a rotating arrangement form;

a transmission belt is sleeved between the driving belt wheel 5 and the driven belt wheel 1 on the same side, and the driving belt wheel 5 is driven to drive the driven belt wheel 1 to rotate;

two opposite driving belt wheel 5 bottoms are equipped with garlic stem cutter 4 respectively, garlic stem cutter 4 is the annular cutter.

The inner ring of the belt is provided with a tensioning device 7 which can firmly clamp the garlic stem by tensioning the belt.

A driving shaft 8 is arranged on the driving belt wheel 5, and the driving shaft 8 penetrates through the base 3; the driving belt wheel 5 is driven to rotate and drive the belt to clamp and transmit through the power drive of the driving shaft 8, and the cutter rotates to cut.

The 3 side of base is fixed and is equipped with installation otic placode 2, is equipped with the mounting groove on the installation otic placode 2. The mounting lug plate 2 is perpendicular to the base 3 and arranged in the same direction as the penetrating direction of the driving shaft 8.

The support part can adopt a belt clamping type whole garlic conveying support in the prior art, a universal joint coupler 9 is arranged on the bottom surface of a driving belt wheel of the conveying support, and the universal joint coupler 9 is connected with a driving shaft 8 of the rod cutting device part and serves as power of the driving shaft 8. The cutting rod device is integrally fixed by matching the fixing of the mounting lug plate 2 on the bottom surface of the transportation bracket. In the whole garlic conveying process, the garlic stems are cut off by the stem cutting device, and the garlic heads are left.
