Example (b): as shown in attached figures 1-8, a compound feed special for grouper fries comprises fish meal with the particle size of 0.10-0.15mm, krill meal with the particle size of 0.15-0.20mm, corn meal with the particle size of 0.20-0.25mm and soybean meal with the particle size of 0.30-0.40 mm.

In this embodiment, the corn flour and the soybean meal are vegetable powder, and the fish meal and the krill meal are animal powder, which are relatively more difficult to digest and poorer in adhesion performance and cohesion performance, so that the particle size of the animal powder is smaller than that of the vegetable powder in the initial direction, and finally the four different particle size ranges are determined according to different nutritional ingredients of the animal powder.

The final feed particles for the grouper fries are ensured, and have at least the following two advantages: 1. the nutrient substances are easy to digest and absorb; 2. the floating performance of the feed is enough, and the feed is not easy to be decomposed too fast.

The production method of the special compound feed for the grouper fries comprises the steps of preparing the fish meal, the krill meal, the corn meal and the soybean meal by using a movable knife type crusher, wherein the rotating speed of a main shaft of the movable knife type crusher is 4500-5000 r/min.

In this embodiment, four kinds of powder may use one main shaft rotation speed, and even the blanking speed may be the same, and the four different particle size ranges may be obtained by only adjusting the density of the cutter body of the movable knife type pulverizer, which is very convenient, and from the viewpoint of equipment structure, there is no need to use additional components such as a controller, a blanking pipeline valve, and the like.

The utility model provides a movable blade crusher, includes barrel 11, apron 12 to and feed inlet 13, still including setting up square combination post unit 1 on the barrel 11 cup joints the setting and is in blade frame unit 2 on the square combination post unit 1 sets up on the square combination post unit 1 and be used for density adjustment blade frame unit 2's clamp plate unit 3 articulates the setting and is in on the feed inlet 13 and be used for by baffle unit 4 of clamp plate unit 3 jack-up, and set up be in on the baffle unit 4 and be used for jack-up on the clamp plate unit 3 the initiative rotor plate unit 5 of baffle unit 4.

The general method of use and advantages of the movable blade mill in this embodiment are as follows.

First, blade frame unit 2 has initial density, and the rubbing crusher was opened this moment, barrel 11 department drops crushing material, if crushing material is too big, then inwards promotes pinch-off blades unit 3, immediately baffle unit 4 is rotatory perk also, this moment the effective feeding area of feed inlet 13 diminishes, blade frame unit 2's quantity does not change, promptly for increase crushing strength, and the particle diameter of crushed aggregates will diminish, otherwise then the grow.

Secondly, the clamping plate unit 3 is not moved, the baffle plate unit 4 is jacked up by the active rotation plate unit 5, and is also rotated and tilted to reduce the effective feeding area, at this time, all the blade frame units 2 are still effective, so that compared with the first adjusting mode, the second adjusting mode has the function of reducing the particle size to a small extent.

For example, if the initial blanking diameter is 0.4mm, the adjustment method of the first bar, i.e. tightening the crushing cutter head and rotating the lifting vertical rotation plate, is required to obtain a blanking diameter of 0.2mm, and if the blanking diameter is 0.3mm, the adjustment method of the second bar, i.e. rotating the lifting vertical rotation plate alone, is required to obtain a blanking diameter of 0.3 mm.

Finally, the flap unit 4 is coupled to the clamping plate unit 3, in order to avoid the clamping plate unit 3 being present during the fall of the material, which would otherwise not be crushed at the clamping plate unit 3.

The square combination column unit 1 comprises a middle square column 101, two end columns 102 which are arranged on the middle square column 101 and are inserted into the cylinder 11, and chamfer threads 103 which are arranged on the middle square column 101 and are used for being screwed with the clamping plate unit 3.

In this embodiment, the structural combination of the middle square column 101 and the chamfer threads 103 is a common threaded column, and four arc-shaped bands are cut off, so that the clamping plate unit 3 can be screwed and the blade frame unit 2 can be driven to rotate together.

Blade frame body unit 2 is including cup jointing the setting square frame 201 on the square post 101 in middle part, the setting is in crushing tool bit 202 on the square frame 201 lateral surface, and set up two adjacent jacking spring 203 between the square frame 201.

In this embodiment, for example, only 7 jacking springs 203 are needed for 8 square frames 201, so as to finally ensure that the distance between 8 groups of crushing cutter heads 202 is flexible and adjustable, and finally the distance parameter is fed back to the particle size of the crushed material.

The clamping plate unit 3 includes a square hole sliding plate 301 which is sleeved on the middle square column 101 and located at one end of all the blade frame units 2, two fastening nuts 302 which are arranged on the chamfer threads 103 and are respectively used for clamping the square hole sliding plate 301 and the square frame 201 at the most lateral side of the other end, and balls 303 which are arranged on the side surface of the square hole sliding plate 301 and are used for rolling on the baffle plate unit 4 or the active rotation plate unit 5.

In this embodiment, the fastening nut 302 directly clamping the square frame 201 is fixed, and the fastening nut 302 clamping the square hole sliding plate 301 can rotate left and right to move, so as to ensure that the crushing strength of the crushing cutter head 202 is flexible and adjustable, and finally, the balls 303 change the original sliding friction between the square hole sliding plate 301 and the baffle plate unit 4 or the active rotation plate unit 5 into rolling friction, so as to greatly reduce the wear speed.

The shutter unit 4 includes a base plate 401 disposed at a position away from the trough a in the feed port 13, a hinge shaft 402 disposed on the base plate 401, a vertical rotation plate 403 disposed on the hinge shaft 402, and a torsion spring disposed on the hinge shaft 402 and configured to press the vertical rotation plate 403 against the balls 303.

In this embodiment, after the vertical rotating plate 403 is rotated and tilted, the effective feeding area of the feeding hole 13 is reduced, the falling amount of the material in unit time is reduced, the number of the crushing cutter heads 202 below is not changed, the density is increased, the whole crushing strength is increased, and the falling crushed material can obtain a smaller particle size.

The torsion spring is disposed on the hole of the vertical rotation plate 403 and the hinge shaft 402 according to the prior art, so as to prevent the vertical rotation plate 403 from rotating and tilting accidentally.

The active rotating plate unit 5 comprises a slot 501 arranged on the side surface of the vertical rotating plate 403, and a clamping-state hinge plate 502 arranged in the slot 501, and used for rotatably jacking the vertical rotating plate 403 in a manner that the lower end edge of the hinge plate is rotated to be opened and then pressed on the ball 303.

In this embodiment, when the square hole sliding plate 301 is not changed and the density of the crushing cutter head 202 is also not changed, the clamped hinge plate 502 is broken off, and the vertical rotating plate 403 can be rotated and lifted up from the open slot 501 to rotate and tilt, so that the area of the effective feed port is reduced, the falling amount of the material in unit time is reduced, and the particle size of the crushed material can be reduced to a small extent.

The clamped hinge plate 502 refers to a hinge shaft thereof, and a large friction force exists between the hinge shaft and the hinge groove of the slot 501, and the friction force ensures that the clamped hinge plate 502 can not rotate and open without falling.

In addition, when the clamped hinge plate 502 is opened, the square hole sliding plate 301 may be fixed to inwardly tighten the crushing head 202, i.e., the position of the square hole sliding plate 301 relative to the hinge axis position line b is not fixed, and the active rotation plate unit 5 is essentially a "aggravating switch" for reducing the particle size of the crushed material.

Chamfers for receiving the balls 303 are arranged on the vertical rotating plate 403 and the upper end hinge plate 502.

In this embodiment, the chamfer functions to make the balls 303 slide onto the vertical rotating plate 403 and the upper hinge plate 502 more smoothly.

Compared with the square hole sliding plate 301, the vertical rotating plate 403 is always at a smaller horizontal distance from the trough a.

In this embodiment, the effective falling area formed at the vertical rotating plate 403 is always smaller than or equal to the distribution range of the crushing cutter 202, so as to ensure that all the materials can be hit by the crushing cutter 202.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
