Agricultural straw smashing device

Abstract

The invention discloses an agricultural straw smashing device. The agricultural straw smashing device comprises a device body. The top end of the device body is provided with a feeding component. Thefeeding component comprises a feeding port, a baffle plate, a rotation shaft and a reset spring. The interior of the feeding component is provided with the feeding port. The side wall of the interiorof the feeding port is rotatably provided with the baffle plate through the rotation shaft. The reset spring is fixedly installed between the baffle plate and the side wall of the feeding port througha spring fixing base. The agricultural straw smashing device is scientific and rational in structure, safe and convenient in use, and provided with the feeding component. After straw is smashed, thestraw adhered to the inner wall of the device body can be effectively blown away through a cleaning fan, and the adhered straw is recovered, so the clean and tidy interior of the device body is effectively guaranteed. Through a dust blocking screen plate, the straw can be effectively prevented from entering the cleaning fan after smashed, so that the cleaning fan is failure and cannot be used. Through a fixing ring and an internal thread, the dust blocking screen plate is conveniently detached and cleaned.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural straw crushing device. Background technique [0002] The straw crushing device can crush corn stalks, straws, peanut skins, bean stalks, firewood and other combustible crop waste stalks, which effectively avoids the waste burning of these crop straws, protects the environment well, and effectively develops renewable energy. The machine has reliable performance, simple operation and convenience. The equipment has a wide range of raw materials and can be used for combustible crop waste stalks such as corn stalks, straws, peanut skins, bean stalks and firewood. In the prior art, the straw crushing device has the following disadvantages : During the crushing process of straw, due to the conduction between the feed inlet and the crushing box, the crushed straw splashes from the discharge port. On the one hand, the crushed straw flies in the air, which wi...

Problems solved by technology

[0003] The present invention provides an agricultural straw crushing device, which can effectively solve the problem that the crushed straw splashes from the discharge port due to the conduction between the feed port and the crushing box during the crushing process of the straw proposed in the above-mentioned background technology. On the one hand, the crushed straw flies in the air, which will pollute the environment; on the other hand, it will cause waste of straw; the inside of the crushing device needs to use the gear box to drive the crushing roller to rotate in the opposite direction, and the use of the crushing device for a long time will cause the gearbox The friction between the internal gears increases and affects the normal use of the device body; when the straw is crushed, the crushed straw will still remain on the inner wall of the crushing box and the surface of the crushing roller and cannot be cleaned, which will cause the crushed device body to be damaged. The interior is relatively dirty, which will affect the normal use of the device body next time; in the prior art, the length of the crushing device for crushing straw has a certain limit. If the length of the straw is too long, it may cause the crushing roller inside the device body to stop rotating, which will cause Seriously affect the service life of the crushing device, the straw needs to be pretreated, which reduces the efficiency of straw crushing; the crushed straw still contains high moisture, on the one hand, it will affect the normal recycling and storage of straw, on the other hand, Straw juice will be contaminated inside the crushing device, causing corrosion on the inner wall of the device body
