Description

Technical Field

[0001] The utility model relates to the field of pulverizers, in particular to a residue pulverizer for agricultural biogas fermentation. Background Art

[0002] At present, a Chinese utility model with the announcement number CN211665083U discloses a residue crusher for agricultural biogas fermentation, including a crushing box, a feeding port is fixedly installed on the upper end of the crushing box, a transmission device is inserted and connected to the right front end of the crushing box, a discharge port is fixedly connected to the lower left end of the crushing box, a fixed drag is welded to the lower right end of the crushing box, a crushing device is fixedly installed on the upper end of the fixed drag, and the left part of the crushing device passes through the right end of the crushing box and is located in the crushing box, and the four corners of the lower end of the crushing box are welded with support columns, and a filter plate and an inclined plate are fixedly connected to the lower part of the crushing box. The residue crusher for agricultural biogas fermentation described in the utility model, by setting a crushing device, realizes that two groups of crushing leaves crush the residue, the crushing is sufficient, the efficiency is high, and the energy saving and consumption reduction is reduced. By setting a transmission device, the agricultural residue can be first stored in the fermentation chamber for preliminary fermentation, and the fermentation speed in the later stage is accelerated. It is highly practical and can be widely promoted and used.

[0003] The existing residue crushers, when in use, put organic materials such as straw and weeds into the machine, which are then crushed by the crushing mechanism. There are other problems during use. For example, since the straw and some weeds are long, it is difficult to stuff them all in at once. After the long materials are stuffed in, there will be less contact between the crushing blades, which reduces the processing efficiency of the equipment. In addition, the equipment does not have a dust collection and filtration function. The residue will produce a lot of dust during the crushing process, and the dust will drift outward after being discharged with the residue particles. If it is inhaled by people around, it will threaten human health. The practicability is low. In order to solve the above-mentioned problems, we propose a residue crusher for agricultural biogas fermentation. Utility Model Content

[0004] The utility model aims to provide a residue crusher for agricultural biogas fermentation, which solves the problem that the existing crusher is inconvenient to crush longer material residues and has no dust collection and filtering function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a residue crusher for agricultural biogas fermentation, comprising a cylinder and a crushing mechanism, a frame bolted to the surface of the cylinder, a long material feeding frame installed through the surface of the cylinder, a rotating roller rotatably connected inside the long material feeding frame, cutting blades equidistantly welded on the surface of the rotating roller, a second motor fixedly sleeved on one end of the rotating roller, a processing frame installed through the surface of the cylinder, a screening plate embedded in the surface of the cylinder through a through groove, a discharging frame installed through the bottom of the processing frame, a fixed frame bolted to the top of the processing frame, a suction fan bolted to the inside of the fixed frame, and an activated carbon filter screen placed inside the fixed frame.

[0006] By adopting the above technical solution, longer residues can be pre-cut, which is simple and labor-saving to operate, improves the processing efficiency of the equipment, and at the same time has dust collection and filtering functions, thereby ensuring the health of surrounding personnel, improving the surrounding environment, and having high practicality.

[0007] The utility model is further configured as follows: the crushing mechanism comprises a fixed rod, the fixed rod is rotatably connected to the inside of the cylinder, a crushing blade is installed on the surface of the fixed rod, and the bottom end of the fixed rod is fixedly sleeved with a first motor.

[0008] By adopting the above technical solution, through the arrangement of the fixed rod, the crushing blade and the first motor, the residue segments falling into the cylinder can be crushed into particles that can pass through the mesh of the sieve plate and be discharged.

[0009] The utility model is further configured as follows: a protective cover is bolted to the bottom of the cylinder.

[0010] By adopting the above technical solution and providing a protective cover, the first motor can be protected to prevent the first motor located at a lower position from being damaged by collision with foreign objects.

[0011] The utility model is further configured as follows: a universal wheel is installed at the bottom of the frame, and a brake pad is installed on the surface of the universal wheel.

[0012] By adopting the above technical solution and setting the universal wheels, it is convenient for personnel to move the equipment.

[0013] The utility model is further configured as follows: the top and the bottom of the activated carbon filter screen plate are both clamped with clamping seats, and the other sides of the two clamping seats are bolted to the fixing frame and the processing frame respectively.

[0014] By adopting the above technical solution, the activated carbon filter screen can be limited by setting the holder to prevent the activated carbon filter screen from tipping over under the influence of wind.

[0015] The utility model is further configured as follows: a dustproof net is installed on the top of the fixing frame.

[0016] By adopting the above technical solution, the dustproof net can be provided to prevent dust from falling into the suction fan through the air outlet.

[0017] The utility model is further configured as follows: the rotating roller and the cutting blade are both made of stainless steel.

[0018] By adopting the above technical solution, the rotating roller and the cutting blade have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. When the utility model is in use, shorter residues can be directly put in through the top of the cylinder, while longer residues need to be fed in from the long material feed frame and the second motor is started. After starting, the second motor will drive the rotating roller to rotate, and the rotating roller will drive the cutting blade to cut the longer residues when rotating. The cut residues will fall downward into the cylinder, so that the longer residues can be pre-cut, the operation is simple and labor-saving, and the processing efficiency of the equipment is improved.

[0021] 2. The utility model starts the suction fan when the residue is broken. After the suction fan is started, the impeller inside it will rotate. The suction generated by the rotation of the impeller will suck in the smoke and dust. After being sucked in, the smoke and dust will pass through the activated carbon filter screen before being discharged outward. The activated carbon filter screen will intercept impurities in the smoke and dust, and can have dust collection and filtering functions, thereby protecting the health of surrounding personnel, improving the surrounding environment, and having high practicality.
