[Industrial applications]

 The present invention relates to a processing machine for branching down tree trees in a street or a park to finely crush pruned branches or leaves.

[0002]

[Prior art]

 Conventionally, there is no processor of this kind, and when a tree or a tree in a park is dropped down, workers first pick up the branches and leaves that have fallen to the ground, and then the branches and leaves are trapped. It was loaded on a truck such as a truck and transported to a designated treatment site, and then incinerated at the treatment site.

[0003]

[Problems to be solved by the device]

 However, the conventional work described above has various disadvantages as described below. First, since the pruned branches and leaves were loaded into the loading vehicle in the pruned state, the bulkiness reduces the loading capacity, resulting in an increase in the number of loading vehicles or a round trip between the site and the treatment plant. If we did not increase the number of times, we would not be able to deal with it, resulting in soaring transportation costs. In addition, the large amount of smoke generated by incinerating the large amount of branches and leaves that were transported to the treatment plant caused smoke damage to nearby residents.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to automatically and continuously perform a two-step pulverization process, thereby It is an object of the present invention to provide a branch and leaf crushing and discharging processor capable of efficiently crushing and dropping the crushed branches and leaves into chips.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the technical means of the present invention are: a first treatment section for finely crushing pruned branches and leaves thrown in through a feeding hopper; and a branch leaf crushed by the first processing section. A second processing unit that guides it through a duct and further crushes the finely crushed branches and leaves into chips and discharges it, and is installed at the discharge port of the second processing unit and crushed to a certain particle size. And a pedestal on which the first processing section and the second processing section are placed, and the first processing section has a rotatable drum. A plurality of cutters for crushing branches and leaves are provided on the peripheral surface at desired intervals, and the second processing unit is provided so as to be respectively swingable with respect to the rotary shaft, and is rotationally operated in accordance with the rotation of the rotary shaft. A plurality of cutters for crushing leaves and leaves and a cutter for crushing the leaves and leaves. Each branch leaf crushing cutter passes between the slits during rotation of the blade, and multiple comb blades projecting from the inner surface of the casing are arranged so that the branches and leaves are crushed when they rub against each other. The discharge limiting section has a large number of discharge holes through which only crushed substances having a predetermined crushing particle size or smaller can pass.

[0006]

[Action]

 By the above technical means, the pruned leaves thrown in through the feeding hopper are first sent to the first processing section, and finely cut by a cutting cutter for branching leaves provided on the rotating drum peripheral surface so as to cut them. The shredded wood pieces (fine pieces) are sequentially sent to the second processing section through the duct by the centrifugal force of the drum. Then, the wood pieces (thin pieces) sent to the second processing unit are further finely crushed between the plurality of rotating blade crushing cutters and the plurality of comb blades. Then, only the wood chips crushed to a certain size or less fall through the discharge holes of the discharge control section and are discharged.

[Effect of device]

 Since the present invention has the above-mentioned configuration, the conventional problem of high transportation cost can be sufficiently solved by crushing the pruned branches that have been dropped down into chips in the field to improve the transportation efficiency. By automatically and continuously carrying out the two-stage pulverization process, a novel and useful pulverization / discharging treatment machine of branches and leaves that can efficiently pulverize the branches and leaves into chips can be provided.

That is, a two-step crushing process in which thick branches and leaves are first crushed to some extent by the first treatment section, and the finely crushed branches and leaves (wood chips) are further crushed by the second treatment section to obtain a certain particle size. Since it is configured to automatically and continuously perform, it is possible to reduce the efficiency of crushing thick branches and leaves with a single crusher for a long period of time until a certain particle size is reached until a certain particle size is reached. The crushing can be completed well and the workability can be improved and the working time can be shortened.

Further, unnecessary branches and leaves after branching, which have been simply discarded conventionally, are pulverized into chips and discharged by using the processing machine of the present invention, so the chip material after the processing is processed. It is also possible to recycle as fuel chips, soil improvement material or mulching material, which not only solves the problems of waste disposal that had been present in the past, but is also very useful.
