Description

Technical Field

[0001] The utility model relates to the technical field of tool shearing, in particular to a tool shearing structure. Background Art

[0002] The tool cutting structure is a common cutting method. In the wider field of mechanical processing, the relative motion between the tool and the workpiece is divided into main motion and feed motion. The main motion is the most basic motion, which makes the workpiece and the tool produce relative motion for cutting, while the feed motion continuously puts the cutting layer into the machine. In agricultural machinery, such as medium-sized forage choppers, it can be divided into two types according to the form of the cutting part: scraper type and wheel knife type.

[0003] In the prior art, people are paying more and more attention to the recycling of straw. For example, straw has high nutritional value as sheep feed. Usually, straw needs to be chopped before it is easy to store and transport. However, the common chopped mechanism is not easy to cut the relatively wet straw, and it needs to be chopped multiple times, which has low efficiency in crushing the straw. How to invent a tool chopped structure to improve these problems has become a problem that technicians in this field need to solve urgently. Utility Model Content

[0007] Both ends of the plurality of mounting frames are fixedly connected with sliders slidably connected with the inner wall of the slide groove, and the inner wall of the mounting frame is installed with a movable guillotine;

[0008] A plurality of driven wheel grooves are installed on both sides of the machine body, one end of the driven wheel groove is rotatably connected to the inner wall of the machine body, and an eccentric shaft is fixedly connected to the outer wall of the driven wheel groove.

[0009] Preferably, the feed opening is a notch inclined downward, and the output end of the motor is fixedly connected to one end of the active pressure roller.

[0010] Preferably, both ends of the active pressure roller and the driven pressure roller are rotatably connected to the inner wall of the machine body, one end of the active pressure roller is fixedly connected to a driving gear, and one end of the driven pressure roller is fixedly connected to a driven gear meshing with the driving gear.

[0011] By adopting the above technical solution, the motor is started to rotate the active pressing roller, and at the same time, the driving gear at one end of the active pressing roller cooperates with the driven gear to rotate the driven pressing roller. At this time, the straw is put into the machine through the top of the machine body, compressed by the pressing roller, and then transported to the subsequent chopping mechanism for crushing.

[0012] Preferably, the outer wall of the sliding block is fixedly connected to a limiting shaft, and the outer wall of the limiting shaft is rotatably connected to a connecting rod.

[0013] Preferably, the outer wall of the eccentric shaft is rotatably connected to the inner wall of one end of the connecting rod, and the outer wall of one of the driven wheel grooves is installed with a first transmission belt that is transmission-connected to the driving wheel groove.

[0014] Preferably, a second transmission belt for transmission connection is installed on the plurality of driven wheel grooves on the other side.

[0015] By adopting the above technical solution, in the process of conveying the straw, the active wheel groove at one end of the driven pressure roller cooperates with one of the driven wheel grooves to make the connecting rod drive the mounting frame to slide back and forth, and at the same time, multiple driven wheel grooves on the other side rotate synchronously under the action of the second transmission belt, so that the movable guillotines on the multiple mounting frames slide back and forth and cooperate with the fixed guillotine to crush the straw.

[0016] The beneficial effects of the utility model are:

[0017] The starting motor rotates the active pressure roller, and at the same time, the active wheel groove at one end of the driven pressure roller cooperates with the first transmission belt to rotate one of the driven wheel grooves, and at the same time, multiple driven wheel grooves on the other side rotate synchronously under the action of the second transmission belt, so that the movable cutters on the multiple mounting frames slide back and forth and cooperate with the fixed cutters to crush the straw and then discharge it through the slide. The straw is put in through the top of the machine body and squeezed and transported by two pressure rollers. The wet straw is compressed to reduce the moisture inside it, and then the straw is crushed by the cooperation of multiple cutters to improve the crushing efficiency.
