Abstract

PROBLEM TO BE SOLVED: To solve problems on secondary crushing and crushing of soft grass or trees, in a tree crusher (hammer crusher). SOLUTION: This crushing chamber structure in the tree crusher is provided with a partition plate 4 and a partition blade plate 3, by both of which a secondary crushing stage of the crushing process using the crusher is formed through utilization of wind pressure and centrifugal force caused when the crushing operation is performed, and also has a feed roller 1, crushing hammers 2 and an intermediate sprocket, each of which is movable in a linked manner with an engine while interposing a centrifugal clutch between them, wherein when any clogging with a crushed material is caused in the crushing chamber, the linkage of each of the above devices 1, 2, etc., with the engine is temporarily released, to enable free rotation of the device and easy removal of the clogging crushed material.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a structure which was invented during the development of a machine which mainly performs tree crushing. The tree crushing system of the hitherto-free hammer type (impact crushing method) which has been manufactured so far has an excellent impact crushing ability, but the biggest disadvantage is the centrifugal wind pressure generated by the high speed rotation of the free hammer. Due to the centrifugal wind pressure, the debris that has completed the primary pulverization moves outside and outside the free hammer and steps. The deposited pulverized material was softer and lighter, and was pushed back to the inlet, so that the pulverized material could not be pulverized. In addition, due to the clogging phenomenon, an overwork state occurs and the engine stops. Therefore, if this centrifugal wind pressure is used, secondary pulverization becomes possible, and pulverization of weeds, straws, weeds, etc., and fibrous peach mulberry kabosu yuzu, etc., which were not possible in the past, has become possible. This provides the operator with much higher efficiency and simplicity of removing the crushed material, and is effective in rapidly growing the compost when composting the crushed material.

BACKGROUND OF THE INVENTION This was a fatal flaw in the currently used blow-milling method. This is different from cutting and crushing with a knife, because of the impact crushing, it is not possible to cut and crush decisively and it is not possible to cut the fibrous material of fibrous tree soft plant flour,
Even if it is made, the amount is small, and the balance between the amount to be charged and the amount to be crushed is lost, so that the engine cannot be discharged and the engine stops. Once the engine has stopped, considerable time and skill are required to remove the crushed material that has clogged the crushed portion. This is because the step is pressed in the direction of the feed roller by a strong spring in order to ensure that the crushed material bites in and to prevent the danger of the crushed material jumping back. In order to remove the crushed material in a stopped state, a gap is provided between the step and the feed roller, a metal rod is held, and the crushed material that has been cut is taken out by leverage. According to the experience so far, working with women is almost impossible and even men need two people.

[0003]

As a problem of claim 1, the disadvantages of the impact pulverization are that the pulverized material is coarse and re-pulverization is required, and that weed straw is a tree with strong fibrous substances.
It was not possible to grind kabosu yuzu. Therefore, the research was made based on the recognition that compensating for this drawback was an important problem, and the following structure was found to be the best. Another object of the present invention is to provide a solution to a means for removing the crushed material by stopping the engine when the crushed material bites between the step and the biting roller during the crushing operation. The state in which the pulverized material is clogged is strongly suppressed by the three points of the step, the feed roller and the hammer so that the pulverized material does not escape. To unlock this requires considerable technical skills and experience. This can be done easily.

[0004]

Embodiments of the present invention will be described with reference to the drawings. Claim 1 Drawing. The first condition is that trees to be crushed are fed to feed rollers at an angle of 55 ° to 70 °. In order to supplement this condition, a partition blade plate and a partition plate are provided. The partition plate plays an important role in controlling and utilizing the wind pressure generated by the high-speed rotation of the hammer to perform secondary pulverization. The gap between the tip of the feed roller and the tip of the hammer is kept at 3 mm to 4 mm.
As for the pulverized material, the pulverized material that has passed by the diameter of the sieve pierced on the screen falls to the lower portion to become a pulverized material. The effects of the above device configuration will be described. Put the trees to be crushed into the slot. Even if it is thrown in arbitrarily, the partitioning plate enters the pulverizing step by the feed roller at an angle most suitable for pulverization. In the conventional impact crushing method, most of them are driven by the high speed rotation of the hammer.
It is blown off by the centrifugal force with the outer side and falls down in the downward direction only by one impact crush. The crushed material having a high fibrous property becomes a thread and is entangled with the hammer, halving the utility of the hammer and eventually interrupting the crushing work. The invented method uses a wind pressure and a centrifugal force generated by the hammer to pulverize the pulverized material by a hammer and collides the pulverized material with a partition blade plate to guide the pulverized material downward. The secondary grinding is performed by the gap. The hammer and the partition plate rotate in the same direction, but the speed of rotation is varied. Claim 2 Drawing 2. Cross section A hexagonal bolt for manual reverse rotation is press-fitted into the center of the roller sprocket, and a clogging release handle is detachably interposed. The roller sprocket, the centrifugal clutch, and the intermediate sprocket are connected by a V-belt chain or the like, and all parts operate by rotation of the engine. When the crushing ability of the hammer shown in FIG. 1 decreases, the centrifugal clutch stops the rotation of the feed roller, stops the supply of the crushed material, and waits for the ability of the engine to recover. When the recovery of the engine recovers, the centrifugal clutch of FIG. 2 operates to operate the feed roller to supply the pulverized material. The structure is as described above. If the crushed material is clogged during the crushing operation and the engine is stopped, switch off the engine, insert and remove the removable, ie, release, hook into the hex bolt for manual reverse rotation, and rotate the release, handle, manually. .
Crushed clogs can be easily removed safely.

According to the present invention, it is possible to perform secondary pulverization by the impact pulverization method, which has been impossible in the past, and also to pulverize soft pulverized material such as grass mulberry peach. It is.

Claims (2)

[Claims] 1. A certain gap is provided between the feed roller and the free hammer, and a partition blade plate is provided between the feed roller and the free hammer. Due to this relationship, the ground material having high hardness is secondarily ground to reduce the size of the ground material. Further, the fibrous pulverized material is hit and pulverized by a gap between the feed roller and the free hammer. Therefore, this gap is restricted to 3 mm to 4 mm. The fibrous pulverized material is relatively light in weight and scattered in the air due to the wind force generated by the rotation of the free hammer, causing play and reducing the pulverization efficiency. In order to prevent this phenomenon, the injection angle of the pulverized material is controlled. It was clarified by experiments that this angle was the best angle of 55 ° to 70 °. 2. If the crushed material becomes too thick and becomes inoperable due to being caught between the feed roller and the free hammer / partition blade plate, a centrifugal clutch is interposed between the roller sprocket and the intermediate sprocket to eliminate the crushed material, and the feed roller can be moved freely. Structure that eliminates crushed material by rotating
