Variable-distance straw cutting-off device

Abstract

The invention discloses a variable-distance straw cutting-off device, relates to the field of environmental-friendly mechanical equipment, and is used for solving the problem that lengths of straws cut off by an existing straw cutting-off device are uncontrollable. The variable-distance straw cutting-off device comprises a feed inlet, a straw chopper and a discharge port, and further comprises a conveying belt, a top cover, a crank connecting rod mechanism, a motor, a baffle and a cutting-off table; the top cover comprises a first top cover and a second top cover; the feed inlet is formed above one end part of the conveying belt; the first top cover is arranged at the upper part of the conveying belt; a first sliding rail is arranged at the top of the first top cover; a plurality of combing pillars pointing to the conveying belt are arranged on the first sliding rail; an end part, which is far away from the feed inlet, of the first top cover is provided with the straw chopper and the cutting-off table arranged up and down; the first top cover and the second top cover are respectively arranged at both sides of the straw chopper; the baffle is arranged at an end part of the second top cover; a second sliding rail and a pulley are arranged on the side wall of the second top cover; the pulley is fixedly connected with the baffle. The variable-distance straw cutting-off device has the advantages that the structure is simple; the variable-distance straw cutting-off device is applicable to various straw cutting-off; the cutting-off length is accurate and controllable.

Description

technical field [0001] The invention relates to the field of environmental protection machinery and equipment, in particular to a variable-pitch straw cutting device. Background technique [0002] In China's traditional planting industry, a large amount of auxiliary products such as rice straws are produced, which occupy a large amount of space. The traditional method is to burn or discard them. During the incineration process, a large amount of dust and harmful gases will be generated, seriously polluting the air and The environment brings difficulties to people's life and production. [0003] With the improvement of national environmental protection requirements, straw burning has been banned. Therefore, there have been many straw recycling processes, which require operations such as coarse crushing, drying, fine crushing, and molding of the straw. Coarse crushing requires the use of a straw cutting device. The traditional straw cutting device has a complex structure, lo...

AI Technical Summary

Problems solved by technology

Coarse crushing requires a straw cutting device. The traditional straw cutting device has a complex structure, low cutting efficiency, and different product specifications.

[0004] The utility model with the patent application number CN201620367940.9 discloses a multi-guillotine equidistant straw cutting machine, including a box body, a middle guillotine, a left guillotine, a setting rod, a connecting block, a guillotine rod, a spring, a stop rod, an upper pulley, Motor, belt, cam, lower pulley and right guillotine; the middle guillotine is set in the middle of the setting bar and fixed with screws; the left guillotine is set at the left end of the setting bar and fixed with screws; the right guillotine is set at the right end of the setting bar , and fixed with screws; the setting rod is arranged under the connecting block and fixed with screws; the guillotine rod is arranged above the connecting block and fixed with screws; the blocking rod is arranged in the middle of the guillotine rod and runs through the guillotine rod Upper second straight rod and third straight rod; the second straight rod is arranged at the left end of the blocking rod and runs through the blocking rod; the third straight rod is arranged at the right end of the blocking rod and runs through the blocking rod. Cutting, but the cutting effect is poor, only one specification of straw can be cut out, the cutting length of straw cannot be set, and it is only suitable for regular and specific length straw cutting, which has limitations
