Straw cutting and crushing equipment

Abstract

The invention discloses straw cutting and crushing equipment which comprises a crushing cylinder. A feeding port with an upward opening is formed at the left end of the crushing cylinder, and a discharging port with a downward opening is formed at the right end of the crushing cylinder; a crushing mechanism is arranged in the crushing cylinder; a storage tank is arranged on the lower portion of the discharging port; and the storage tank is placed on the upper portion of a control mechanism. The densities of tools arranged on transmission shafts in a sleeving mode are sequentially increased from left to right in a gradient mode. In the processing process, straw is cut into different length gradients, the transmission shafts with the high blade densities are prevented from being clamped, and clamping of tool bits due to straw winding is effectively avoided. When the processed straw in the storage tank is accumulated to the predetermined weight, shaft handles overcome the elasticity of a spring to downwards move, a left metal piece and a right metal piece which originally abut against each other are separated through a protruding part, a power supply stops providing power to a motor, and thus the problems that the straw is accumulated at the discharging port, thus the tool bits are blocked, and the equipment is damaged are effectively avoided.

Description

technical field [0001] The invention relates to the field of cutting and crushing equipment, in particular to straw cutting and crushing equipment. Background technique [0002] Straw is the leftover after harvesting in northern agriculture. The common method is to incinerate, which will bring greater environmental pollution. With the encouragement of policies, the straw is often cut and crushed before further processing, which not only effectively disposes of excess straw, but also And it can also create additional economic value, but the existing cutting and crushing device uses a single blade for cutting, and in order to ensure the effect of cutting, it uses a relatively dense blade, which is easy to cause the cutter head to get stuck; not only that, the processed straw in the storage tank After it is full, the power cannot be automatically cut off, which will easily lead to the accumulation of straw at the discharge port, resulting in blockage of the cutter head and dama...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned problems in the prior art, and provide a straw cutting and crushing equipment, which not only effectively avoids the jamming of the cutter head due to the entanglement of straw, but also solves the problem of straw accumulation at the discharge port, resulting in blockage of the cutter head , the problem of damaging the device
