Description

A crushing and returning machine for oil-tea residues

Technical Field

The utility model relates to the technical field of oil-tea residue processing, and more specifically, to a crushing and returning machine for oil-tea residue.

Background Art

In the cultivation and management of oil tea forests, it is necessary not only to prune the branches of oil tea trees, but also to weed and de-shrub the forest land. During these operations, a large number of discarded oil tea and shrub branches and weed stems will be left in the forest land. These debris scattered randomly in the forest land will hinder subsequent operations. At present, the main way for most oil tea forest growers to deal with these debris is centralized stacking, pile burning, and on-site burial, which will not only cause safety hazards and environmental pollution, but also cause a large amount of waste of biomass resources. If these debris can be crushed and returned to the field and spread on the soil surface, it can not only turn waste into treasure and reduce the use of chemical fertilizers, but also have a positive effect on the maintenance of soil moisture. Therefore, it is urgent to develop machinery for crushing and returning oil tea forest debris to the field.

Although many mature crushing and returning machines have been developed, most of them can only crush a single material, and most of them can only crush materials with similar characteristics; CN202320681554.7 discloses a water grass crushing device. In order to prevent the crushed material from winding around the main shaft, a cutting knife is provided to cut the material into small sections before the crushing knife is used to crush it. The overall structure is complex, and the main shaft of the cutting knife may be entangled; CN202320598584.1 discloses a grape branch crushing device, which uses a screen to screen the crushed material. The material that has not been completely crushed will be retained in the screen, which may easily cause the screen to be blocked during screening, affecting the working efficiency of the crusher.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model discloses a crushing and returning machine for oil-tea residues. When working, the driving pulley 202 on the output shaft of the motor 201 drives the fixed axis of the crushing blade shaft 103 fixedly connected to the driven pulley 203 to rotate through the transmission belt 204, thereby driving the moving blade holder 107 and the hammer mounting seat 114 fixedly installed on the crushing blade shaft 103 to rotate, so that the moving blade 109 and the hammer 108 rotate around the crushing blade shaft 103, and the hammer 108 rotates around the connecting hinge with the diameter of the hammer mounting seat 114 under the action of centrifugal force and is thrown away. After weeds, oil-tea tree branches and other debris are put into the crushing chamber 1 from the feed port 101 by workers, the branches and other harder debris will be directly hammered and crushed by the swinging hammer 108, and the longer and more tough debris will be shortened by the cooperation of the moving blade 109 and the fixed blade 106 and then hammered and crushed by the hammer 108. At the same time, the rotation of the crushing blade shaft 103 will also drive the air supply impeller 102 and the centrifugal impeller 110 to rotate. The rotation of the air supply impeller 102 generates wind force to select the debris in the crushing chamber 1 through the wind guide plate 104. After the debris with qualified crushing particle size is blown to the right end centrifugal impeller 110 under the action of wind force, the wind force generated by the rotation of the centrifugal impeller 110 is discharged from the discharge port 111 and returned to the field. The debris with unqualified crushing particle size will not be blown away but will continue to remain in the crushing chamber 1 and continue to be crushed until it reaches the qualified crushing particle size.

When not in operation, the hammer 108 is in a naturally hanging state, and the space in the crushing chamber 1 is large, which is convenient for maintenance and adjustment or replacement of the hammer 108, the movable knife 109 and the fixed knife 106.

The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several replacements and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
