Abstract

The utility model relates to an agricultural disintegrator, composed of a feeding part, a disintegrating room part, a mechanical driving part and a supporting bracket, wherein, the disintegrating room part comprises a disintegrating room chamber composed of a top cover and a lower frame body composing a discharging path, hammer piece assemblies which are arranged in a staggered mode on a transmission main shaft and are positioned at the center of the room chamber, and a sieve below the assemblies. The technical characteristic is that the inner wall of the lower frame body is horizontally vertical wall of a right angle. The technology causes discharging to be smoother, reducing device failure caused by indoor material accumulation.

Description

A kind of agricultural mill

The utility model relates to and a kind ofly be used for crops such as crushing maize, Chinese sorghum or as the agricultural processing equipment of processing feed.

This type of pulverizer, especially relatively more typical with the hammer crusher structure, it is normally by feeding part, the pulverizing chamber part, several parts of mechanical driving part and support thereof are formed, wherein pulverizing chamber partly comprises the pulverizing chamber of being made up of loam cake and the lower frame that has constituted tapping channel, be provided with the filter screen that below the staggered hammer leaf assembly of installing on the transmission main shaft and its, is provided with in the chamber, the main deficiency of its existence is that its lower frame inwall generally adopts and becomes 45-60 ° inclination angle with level, make the very little angle of existence between its inwall and the screen cloth, frictional heat increases viscosity when being pulverized because of material, easier accumulation makes it to form the dead angle, block screen cloth, also made tapping channel become narrow and small, influenced discharging, a large amount of materials are retarded by silt in pulverizing chamber, and cause the card machine, damage machine part, often cleaning.Another defective of its existence is that the loam cake inwall is a shiny surface, only can produce centrifugal bump and rubbing effect to material by the hammer leaf of rotation at a high speed, the material of being processed is ground into fine particle, and a large amount of materials and inwall are done the time spent and are all skidded and nuzzle up, therefore its crush efficiency is lower, causes large granular materials content bigger.In sum, this agricultural mill structure is not satisfactory.

Goal of the invention of the present utility model is to provide the agricultural mill that a kind of discharging is unobstructed, fault rate is low.

Another goal of the invention of the present utility model is to provide a kind of agricultural mill that can improve crushing efficiency and installation effectiveness.

The agricultural mill that the utility model is made of feeding part, pulverizing chamber part, mechanical driving part and supporting bracket thereof, pulverizing chamber wherein partly comprises the pulverizing chamber of being made up of loam cake and the lower frame that constitutes tapping channel, be positioned at the screen cloth below staggered hammer leaf assembly of installing on the transmission main shaft and assembly that chamber central authorities are provided with, its can realize inwall that the major technique of foregoing invention purpose is characterised in that lower frame for the right angle walls of horizontal vertical.

In technique scheme, for improving the crushing efficiency of pulverizer, be fixed with the tooth plate that has some protrusion pointed tooths at the mill housing cover inwall, the mounting means of this tooth plate and loam cake can be the modes that are fixedly connected such as bolt, also can be slideway plug-in mounting mode, promptly be fixed with the guide chute that is used for the plug-in mounting tooth plate in mill housing cover inwall both sides; The lower edge of last benefit is provided with the flexible boss seam that positions of the metal material that utilizes screen cloth.

The utility model agricultural mill that above technical scheme constituted, adopted straight mouthful of channel mode owing to constitute the lower frame of tapping channel, its lower end is smooth the connection with discharging opening, not only enlarged tapping channel, and the angle between lower frame and the screen cloth is expanded effectively, then be difficult between lower frame and screen cloth, forming the dead angle of piling up material, broken material can successfully be discharged through screen cloth with own wt, reduce the card machine that causes because of clogged up with material, the phenomenon of damaging motor, reduced the fault rate of machine.In addition because the tooth plate of the protrusion pointed tooth that the loam cake inwall is installed, make the bigger crushing stress of same generation in material and interior wall friction, the collision, thereby improved breaking capacity greatly to material, improved crushing efficiency, shortened pulverizer to the material grinding time, substantially the primary characteristic that has kept material reduces its thermal viscosity greatly; Again because the tooth plate and the screen cloth of this machine all adopted the plug-in mounting assembling mode, not only make dismounting convenient, quick but also assembly is obviously reduced, it is also simpler and more direct to make it form structure.

Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing is the part sectional structure schematic diagram of the utility model agricultural mill.

Agricultural mill of the present utility model includes feeding part 1, pulverizing chamber part 2, the supporting bracket of mechanical driving part 3 and above-mentioned part thereof, pulverizing chamber part 2 wherein includes the pulverizing chamber of forming with the lower frame 11 that constitutes tapping channel by last beneficial 6, with be provided with in the pulverizing chamber at staggered hammer leaf assembly of installing on the transmission main shaft 10 8 and hard-wired screen cloth 9 below it, the inwall of lower frame 11 is the right angle walls with horizontal vertical, its lower end is smooth the connection with discharging opening 4, its upper end one side is provided with boss seam 5, is positioned at the set boss seam 13 in loam cake 6 lower ends with opposite side, utilize the flexible of screen cloth metal material jointly screen cloth 9 plug-in mountings to be fixed.On loam cake 6 inwalls of this agricultural mill, be fixed with a tooth plate 7 that has some spur teeth, this tooth plate 7 can be fixedly mounted on the loam cake inner wall position in every way, as bolting etc., also can adopt slideway plug-in mounting mode, promptly be provided with the guide chute of plug-in mounting tooth plate 7 in the both sides of loam cake 6 inwalls, the tooth plate 7 that will have certain metal amount of deflection inserts the back along guide chute and installs.Present technique also can be at loam cake 6 inwalls and directly is shaped on some protrusion pointed tooths 12, but its processing capacity is complicated, so should take aforesaid way to install.
