Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of agricultural production equipment, and in particular to a straw crushing device. Background Art
[0002] Straw usually refers to the remaining part of mature crops after the seeds are harvested. During the agricultural production process, a large amount of crop straw is often left in the fields. If these straws are burned directly, it is not only a waste of resources, but the substances produced by burning will also pollute the environment. On the contrary, by crushing the straw for recycling and reuse, it can effectively replace the ineffective burning of straw, thereby better protecting the environment and contributing to the development of renewable energy. Since the straw crushing process is relatively laborious and the amount of straw is large, it usually requires the help of professional straw crushing equipment. These devices use high-speed rotating blades to crush and cut the straw.
[0003] As for the current straw crushing equipment, a large amount of dust is often generated during the operation of the crushing equipment. Since the dust is light in weight, after the dust is separated from the straw fragments, it often floats in the air with the force generated during the cutting process. The high-speed rotating blades will drive the flow of air, which will disperse the dust to various places in the air. The dust is often discharged to the outside of the equipment through the feed channel and exhaust port with the airflow. A large amount of dust may have an adverse effect on the working environment of the equipment, and may also affect the work and health of the staff. In addition, some of the dust will slowly fall to the inner bottom surface of the equipment. However, the interior of the equipment is often unable to be disassembled and cleaned. Long-term dust accumulation may affect the use of the equipment.
[0004] Therefore, those skilled in the art provide a straw crushing device to solve the problems raised in the above background technology. Utility Model Content

[0035] Specifically, the main body mechanism 1 is the main structure of the crushing equipment, which has two groups of cutting and crushing structures. The straw is first roughly cut, and then further crushed, and finally transported to the collection device through the auger 106. The feeding mechanism 2 is located near the upper end of the equipment. The user puts the straw into it and drives it to move into the equipment through the groove roller 204 for continuous cutting. The dust removal mechanism 3 is mainly used to filter the exhaust gas and collect the dust in the air. At the same time, part of the air is blown back to the inside of the equipment at a certain speed through the air supply port 310, so that the deposited dust returns to the air to clean the deposited dust.
[0036] Reference Figure 2 、 Figure 3The main body mechanism 1 includes a supporting shell 101 and a crushing mechanism.

After the straw transmission is completed, the two baffles 203 will automatically close to the middle under the action of the spring clip, which can prevent dust from leaking out through the feed channel 202 to a certain extent and interfering with the work of the staff. The grooved roller 204 is electrically controlled and drives the movement of the straw by rotation to complete the automatic feeding of the straw, which can replace part of the manual operation and reduce the workload.
