Abstract
The utility model discloses a hay cutting machine for machining straws, wheat straws and other grass straws in the paper manufacture industry, fiber board manufacture industry, etc. The hay cutting machine with the advantages of simple and reasonable structure, safe and feasible operation, low power consumption, small impact load during operation and long service life is characterized in that a main axis of the hay cutting machine is arranged on a machine frame and covered by a cylindrical outer cover, wherein the front end and the back end of the outer cover are provided with a feeding port and a discharging port. A plurality of groups of cutters are distributed on the main axis along the axial direction. Each group of cutters comprises a plurality of cutting blades; the end surface of each cutting blade is not vertical to the main axis. An included angle alpha is formed between the cross section of the main axis and the end surface of the cutting blade. A flywheel is arranged at one end of the main axis. The utility model is simple in structure and small in impact and vibration. By the high speed rotation of a plurality of groups of cutters, the straw materials can be continuously cut and rubbed and the dust is exhausted. The cut straw materials have good quality, the straw materials with different length can be processed, and the entire cutting part is covered in the outer cover so that the operation is safe and reliable.
Description
(1) technical field under
The utility model relates to a kind of chaffcutter that industries such as papermaking, fiberboard manufacturing are processed paddy and wheat grass straw and other careless class straw that is used for.
(2) background technology
The present rotor formula chaffcutter that generally uses, its structure is constantly forage to be delivered to the edge of a knife by feeding roller, is cut off by the rotating fly-bar on the rotor.The defective of this structure is: one, complex structure, manufacturing cost height; Two, poor stability, operating personnel's casualty accident happens occasionally; Impact load is big when three, working, and parts are fragile, influence equipment life; Four, energy consumption is higher; Five, long when processing length, evenly during neat forage, the blank quality is better, and during short, the random forage of processing, the blank quality is obviously relatively poor.In addition, also need other auxiliary equipment to carry out dedusting work.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, and a kind of simple and reasonable, handling safety is reliable, energy consumption is low, impact load is little, the life-span is long during work chaffcutter is provided.Simultaneously, make it can process the forage of different quality preferably, and have dedusting function.
Chaffcutter of the present utility model comprises a rack-mounted main shaft, main shaft is housed in the outer cover of a tubular, there are charging aperture and discharging opening in the outer cover rear and front end, at main shaft upper edge axial arranging many group cutters are arranged, each group cutter is made up of along the even blade that distributes and radially install of circumference several, the end face of blade and main shaft out of plumb have an angle α between the cross section of it and main shaft.Main shaft can in order further to improve its stability, can be equipped with flywheel at main shaft one end by motor or other power drive.In addition, the bottom of outer cover also has sieve aperture, and it is communicated with the ash hole of below.
The utility model is simple in structure, impacts, vibration is little, owing to rotate at a high speed by many groups cutter, constantly forage is cut, crumples and remove dust, not only the chaffcutter quality is good, and can process the forage of different length, whole cutting tip is housed in the outer cover simultaneously, thereby handling safety is reliable.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the scheme of installation of blade;
Among the figure: 1 frame, 2 main shafts, 3 outer covers, 4 charging apertures, 5 discharging openings, 6 blades, 7 flywheels, 8 sieve apertures, 9 ash holes.
(5) specific embodiment
As shown in the figure, the main shaft 2 of this chaffcutter is installed on the frame 1, and cover in the outer cover 3 of a tubular, there are charging aperture 4 and discharging opening 5 in the outer cover rear and front end, on main shaft, is placed with many group cutters vertically, each group cutter is made up of several blades 6, each blade evenly distributes and radially installs along circumference, and the end face of blade 6 and main shaft 2 out of plumb have an angle a between the cross section of it and main shaft.In order further to improve its stability of main shaft, flywheel 7 is installed at main shaft one end.During work, forage is sent into outer cover 3 by charging aperture 4, by 6 cuttings of high speed rotation of blade, owing between the cross section of blade and main shaft an angle is arranged, thereby forage promoted vertically, simultaneously organizes cutters and rotates the axial wind-force of generation at a high speed, forage is moved vertically, forage is constantly thrown, is fallen and cut in motion process, crumpled, and to discharging opening 5 discharges, and the dust of taking off is discharged by the sieve aperture 8 and the ash hole 9 of bottom.
Claims (1)
1. chaffcutter, include a rack-mounted main shaft (2), it is characterized in that: the main shaft of described chaffcutter (2) is installed on the frame (1), and cover in the outer cover (3) of a tubular, there are charging aperture (4) and discharging opening (5) in the outer cover rear and front end, on main shaft, be placed with many group cutters vertically, each group cutter is made up of several blades (6), the end face of blade (6) and main shaft (2) out of plumb, between the cross section of it and main shaft an angle a is arranged, flywheel (7) is installed at main shaft one end.
