Abstract

A feed mill is provided, which comprises an upper shell, a lower shell, an upper screen sheet and a lower screen sheet assembled by screen sheet fixing frames at two sides of the shells, a main shaft, and a spinning disk and a hammering sheet both driven by the main shaft. The technical proposal is that a latch plate is arranged between the upper and the lower screen sheets in the milling chamber of the shell, latching grooves are provided circumferentially on the latch plate, the latching grooves at two sides of the latch plate are respectively guided by the screen sheet fixing frames at two sides of the shell, and the upper and the lower latching grooves of the latch plate clamp and fasten the upper and the lower screen sheets on the screen sheet fixing frames. The feed mill fundamentally solves the problems of the prior art, such as low efficiency and inconvenient maintenance; and has the advantages of reasonable design, simple structure, easy replacement of screen sheets, high service performance of equipment and high milling efficiency.

Description

Feed grinder

Technical field

The utility model relates to a kind of feed processing machinery, particularly a kind of improved simple in structure, change sieve sheet processing ease, feed grinder that crush efficiency is high.

Background technology

It is CN2581071Y " a kind of feed grinder " that the design people had once proposed notification number, adopt the fixed head and the bolt of band flanging that the top sieve sheet is fixed on the upper shell in this engine housing crushing chamber, and upper and lower sieve sheet is on the same circumference, thereby the defective that the top sieve sheet stops up when having overcome other pulverizer crushed straw.But find that in actual applications this structure still has unsatisfactory part, mainly shows as: 1, with bolt and fixed head the top sieve sheet is fixed on the upper shell, dismounting is inconvenience very.2, the crushing chamber internal cause of housing does not have and obviously stops the material deceleration device, so cause the speed of material to be machined in the process to reduce, material to be machined and hammer leaf movement velocity is more or less the same, and causes crush efficiency lower.

The utility model content

The purpose of this utility model provides a kind of feed grinder, defectives such as the efficient that it has fundamentally overcome existing pulverizer existence is low, inconvenient maintenance, it is reasonable in design, and the sheet processing ease is sieved in simple in structure, replacing, can significantly improve the serviceability and the crush efficiency of equipment.

The purpose of this utility model is achieved in that this machine comprises upper and lower casing, utilize the upper and lower sieve sheet of the sieve sheet fixed frame assembling of housing both sides, getting rid of of main shaft and drive thereof coiled and hammer leaf, its technical essential is: between the upper and lower sieve sheet in the described housing crushing chamber clamp is set, the spill draw-in groove is set around the clamp, clamp both sides spill draw-in groove utilizes the sieve sheet fixed frame of housing both sides to lead respectively, with the upper and lower spill draw-in groove of clamp upper and lower sieve sheet is held respectively and tensioner on sieve sheet fixed frame.

Described clamp outer surface is provided with the flank of tooth.

Because the utility model is improved on the basis of the basic structure of existing feed grinder, so be easy to realize.The clamp of spill draw-in groove around adopting, this machine is set, and the spill draw-in groove that utilizes clamp holds upper and lower sieve sheet respectively and tensioner in the sieve sheet fixed frame of housing both sides, to replace the mode of former employing bolt and fixed head gravity flow screen sheet, therefore, can fundamentally overcome defectives such as the efficient that has the pulverizer existence now is low, inconvenient maintenance.The sieve sheet fixed form of this machine is compared with existing pulverizer, and the mode that holds is reasonable in design, clamp simple in structure, the processing ease of gravity flow screen sheet.So, the operation of installation and replacing sieve sheet is just more convenient, also laborsaving especially.In addition, can also the flank of tooth be set at the clamp outer surface, processed feed contacts with the flank of tooth of clamp under the hammer leaf of quick rotation drives, when generation stops bump, can reduce the movement velocity of feed, the movement velocity that strengthens between hammer leaf and feed is poor, and this not only can reach energy-conservation effect, and can significantly improve the serviceability and the crush efficiency of this machine.

Description of drawings

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 a kind of concrete structure schematic diagram of clamp among Fig. 1.

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

Sequence number explanation among the figure: 1 upper shell, 2 top sieve sheet fixed frames, 3 top sieve sheets, 4 get rid of dish, 5 clamps, 6 hammer leaves, 7 main shafts, 8 lower houses, sieve the sheet fixed frame for 9 times, sieve sheet, 11 flank of tooth, 12 upper and lower spill draw-in grooves, 13 both sides spill draw-in grooves 10 times.

The specific embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1-3.The specification of the structure of this machine and the structural requirement of existing feed grinder, shape basically identical have just been cancelled bolt and top sieve sheet fixed head that former gravity flow screen sheet is adopted.It comprises upper shell 1, lower house 8, be arranged on the sieve sheet fixed

frame

2,9 of upper and lower casing both sides, be assembled in top sieve sheet 3 in the

fixed frame

2,9, sieve sheet 10 down, motor-driven main shaft 7 and drive get rid of dish 4 and hammer leaf 6, place clamp 5 parts such as grade in the housing crushing chamber.Wherein clamp 5 is arranged between the upper and lower sieve sheet 3,10.Upper and lower spill draw-in groove 12 and both sides spill draw-in groove 13 are set respectively around the clamp 5.The and arranged on left and right sides spill draw-in groove 13 of clamp 5 is connected to respectively on the upper and lower sieve sheet fixed

frame

2,9 of housing both sides, utilizes 2,9 pairs of clamps 5 of sieve sheet fixed frame to lead.With the end face of upper and

lower sieve sheet

3,10, be connected to respectively in the upper and lower spill draw-in groove 12 of clamp 5, with the upper and lower spill draw-in groove 12 of clamp 5 upper and

lower sieve sheet

3,10 is held respectively and tensioner in sieve sheet fixed frame 2,9.For serviceability and the crush efficiency that improves this machine, can the flank of tooth be set at the outer surface of clamp 5, processed feed under driving, the hammer leaf of quick rotation is contacted with the flank of tooth of clamp, when generation stops bump, to reduce the movement velocity of feed, the movement velocity that strengthens between hammer leaf and feed is poor, improves crushing effect.

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

Claims

1. feed grinder, comprise upper and lower casing, utilize the upper and lower sieve sheet of the sieve sheet fixed frame assembling of housing both sides, getting rid of of main shaft and drive thereof coiled and hammer leaf, it is characterized in that: between the upper and lower sieve sheet in the described housing crushing chamber clamp is set, around the clamp spill draw-in groove is set, clamp both sides spill draw-in groove utilizes the sieve sheet fixed frame of housing both sides to lead respectively, with the upper and lower spill draw-in groove of clamp upper and lower sieve sheet is held respectively and tensioner on sieve sheet fixed frame.

2. feed grinder according to claim 1 is characterized in that: described clamp outer surface is provided with the flank of tooth.
