Abstract

The utility model discloses a feed grinder comprising an upper shell and a lower shell, a screen piece assembled through a screen piece fixing frame, a main shaft, and a projecting disc and a hammer piece driven by the main shaft. The feed grinder is characterized in that the screen piece is of an integrated structure; a front end support frame and a tail end support frame are arranged on a material inlet in the upper shell; a limit throat sheet is arranged on the tail end support frame; a middle section support frame is aligned with the material inlet; a front concave clamping groove and concave clamping grooves on two side are respectively arranged on the front end support frame; a spring for compensating length of the screen piece is arranged in the front concave clamping groove; the concave clamping grooves on two sides and the tail end support frame are guided through the screen piece fixing frame; and the screen piece is clamped and tensioned on the screen piece fixing frame through the front concave clamping groove of the front end support frame, the middle section support frame, the tail end support frame and the throat sheet. The feed grinder thoroughly overcomes shortcomings of an existing feed grinder which is un-tight to seal upper and lower half screen pieces, easy to result in loss of coarse materials and inconsistent in screen piece abrasion; and the feed grinder has the advantages of simple structure and easy operation, and is capable of further improving quality of ground materials, prolonging service life of the screen piece, and the like.

Description

Feed grinder

Technical field

The utility model relates to a kind of feed operated implement, particularly the feed grinder of a kind of improved further raising crushing rear material quality and sieve durability.

Background technology

The feed grinder kind of existing iron plate seam is comparatively various, and each is variant for its structure, but they have a general character, are exactly all sieve to be made to the split-type structural of upper and lower two halves, are provided for the fixed mechanism of clamping sieve in centre.As notification number be CN201086021Y " feed grinder ", this machine adopts surrounding that the clamp of spill draw-in groove is set, and the spill draw-in groove that utilizes clamp holds upper and lower sieve respectively and tensioner in the sieve fixed frame of housing both sides, to replace, adopt the fixedly mode of sieve of bolt and fixed head, fundamentally overcome the defects such as pulverizer efficiency is low, inconvenient maintenance.But find that in actual applications this structure still has unsatisfactory part, main manifestations is: 1, owing to adopting upper and lower two halves sieve to divide, be arranged, exist between upper and lower airing sheet poorly sealedly, easily run coarse fodder, cause crush efficiency to reduce, can affect the problem of the quality of crushing rear material.2, due to unbalance stress, cause the wearing and tearing of second sieve fast compared with first sieve, but when changing in order to reach mutual coupling, need to change simultaneously, therefore shortened sieve service life, increased production maintenance cost.

Utility model content

The purpose of this utility model is to provide a kind of feed grinder, it has fundamentally overcome the bad sealing existing between the upper and lower two halves sieve of existing feed grinder, run coarse fodder and the sieve inconsistent defect of wearing and tearing, it is simple in structure, reasonable in design, processing ease, has the further quality of improving crushing rear material, improves the advantages such as sieve service life.

The purpose of this utility model is achieved in that this feed grinder comprises, lower house, utilize the sieve of sieve fixed frame assembling, the throwing disc of main shaft and drive thereof and hammer leaf, its technical essential is: described sieve adopts monolithic construction, feeding mouth in upper shell is provided with head end holder frame and end holder frame, end holder frame is provided with spacing throat sheet, over against locating to be provided with stage casing, hold in the palm frame with feeding mouth, on head end holder frame, be respectively equipped with anterior spill draw-in groove and both sides spill draw-in groove, in anterior spill draw-in groove, be provided with for compensating the spring of sieve length, both sides spill draw-in groove and end holder frame utilize sieve fixed frame to lead, anterior spill draw-in groove with head end holder frame, stage casing holder frame, end holder frame and throat sheet by sieve hold and tensioner on sieve fixed frame.

Along being circumferentially provided with four hammer leaves, mutually vertical between adjacent hammer leaf centered by described main shaft.

The advantage the utlity model has and positive technique effect are: due to the sieve of the utility model employing monolithic construction, the head end holder frame of spill draw-in groove is set by anterior and both sides, and in anterior draw-in groove, be provided for compensating the spring of sieve length, utilize anterior spill draw-in groove, stage casing holder frame, end holder frame and throat sheet that sieve is held and tensioner on the internal circular surfaces of sieve fixed frame, so it is simple in structure, reasonable in design, processing ease.The sieve of above-mentioned monolithic construction has replaced the upper and lower sieve of existing split-type structural, therefore, overcome the bad sealing that existing feed grinder adopts upper and lower two halves sieve to exist, the defect that the material of fine-powdered spills along gap, has advantages of the further quality of improving crushing rear material.Because sieve end is more serious compared with head end wearing and tearing, if adopt the separately design of original upper and lower sieve matching, need whole replacings, and adopt after whole sieve, after head end and end direction transposing, still can continue to use, improve the service life of sieve.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a kind of concrete structure schematic diagram of the present utility model;

Fig. 2 is the structural representation of clamp in sieve in Fig. 1;

Fig. 3 is the side view of Fig. 2.

Sequence number explanation in figure: 1 upper shell, 2 sieve fixed frames, 3 head end holder frames, 4 sieves, 5 end holder frames, 6 spacing throat sheets, 7 hammer leaves, 8 throwing discs, 9 frames, 10 lower houses, 11 stage casing holder frames, 12 hammer leaf bars, 13 main shafts, 14 anterior spill draw-in grooves, 15 springs, 16 both sides spill draw-in grooves.

The specific embodiment

According to Fig. 1 ~ 3, describe concrete structure of the present utility model in detail.Specification, the shape of the structure of this feed grinder and the structural requirement of existing feed grinder are basically identical, just the sieve of monolithic construction has replaced the upper and lower sieve of existing split-type structural, and has changed the structure that a fixing chuck plate that original feed grinder adopts coordinates upper and lower sieve.It comprises the upper shell 1 that matches with lower house 10, is arranged on the lower house 10 in frame 9, utilizes the sieve 4 of the monolithic construction of sieve fixed frame 2 assemblings, the parts such as main shaft 13 and the throwing disc 8 driving and hammer leaf 7.Motor (not shown in FIG.) drive shaft 13 drives hammer leaf bar 12 and hammer leaf 7 High Rotation Speeds.Wherein, in order to improve serviceability and crush efficiency, centered by main shaft, edge is circumferentially provided with four hammer leaves 7 altogether, and mutually vertical between adjacent hammer leaf 7.Feeding mouth both sides in upper shell 10 are respectively equipped with head end holder frame 3 and end holder frame 5, end holder frame 5 is provided with spacing throat sheet 6, over against locating to be provided with stage casing, hold in the palm frame 11 with feeding mouth, on head end holder frame 3, be respectively equipped with anterior spill draw-in groove 14 and both sides spill draw-in groove 16, in anterior spill draw-in groove 14, be provided with for compensating the spring 15 of sieve length, both sides spill draw-in groove 16 utilizes sieve fixed frame 2 to lead with end holder frame 5, and sieve fixed frame 2 is arranged between the head end and upper shell 1 of sieve 4.With the anterior spill draw-in groove 14 of head end holder frame 3, stage casing holder frame 11, end holder frame 5 and spacing throat sheet 6 holds sieve 4 and tensioner on the internal circular surfaces of sieve fixed frame 2.

The use of this machine is identical with the operation of other feed grinder.
