Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinder such as a tree having a retractable hopper for shredder and / or a hopper for chipper provided with a safety guard for storage.

[0002]

2. Description of the Related Art In order to pulverize branch and foliage trees generated by pruning for the purpose of promoting tree growth, and to pulverize and reuse waste wood, for example, Utility Model Registration No. 25
A pulverizer disclosed in Japanese Patent Application No. 65965 and Japanese Patent Application Laid-Open No. 9-66507 has been proposed.

As shown in FIGS. 15 and 16, the above-mentioned Japanese Patent Application Laid-Open No. 9-66507 discloses that a self-propelled truck 1a is
A crusher 3a including a motor 2a, a shredder for crushing the input branches and leaves, a chipper for cutting and crushing the input branches, and a blower for discharging the crushed pieces crushed by the shredder or chipper to the outside. And a power transmission means from the motor 2a to the crushing device 3a, a shredder hopper 8a for feeding branches and leaves to the shredder of the crushing device 3a, and a chipper for feeding branches and trees to the chipper of the crushing device 3a. A crusher, such as a movable tree, is disclosed in which a hopper 9a is attached, and a shooter 11a for attaching crushed pieces discharged by a blower to a desired position at a crushed piece discharge port of a crusher 3a is attached.

Further, as shown in FIGS. 17 and 18, Utility Model Registration No. 2565965 discloses a hopper 9b for putting in a branch and a tree, and the branch and the tree mounted on the hopper and rotating the branch with the principle of a rotary plane. A chipper for cutting, a pulverizing mechanism for pulverizing the cut pieces with a hammer-type pulverizer, a sending mechanism for sending out the pulverized pieces of the pulverizing mechanism by a lifting blade, and a sent pulverized piece behind the chipper. There is disclosed a vehicle-type branch-and-tree crushing apparatus in which a storage platform having a discharge mechanism for discharging stored crushed pieces and storing the stored crushed pieces is mounted on a vehicle. The hopper 9b is fixed to the fixed hopper section 91.
b (corresponding to the base end of the present invention) and the movable hopper 92b (corresponding to the storable portion of the present invention).
It is disclosed that an opening / closing lid 93b (corresponding to a storage safety guard of the present invention) rotatably supported by a cantilever is provided at an opening of the fixed hopper section 91b when b is in a retracted state. .

[0005]

However, in the pulverizer disclosed in Japanese Patent Application Laid-Open No. 9-66507, as shown in FIGS. 15 and 16, the shredder hopper 8a and the chipper hopper 9a are self-propelled trolleys 1a. From the outside, and there is a problem that it is not easy to use because it is obstructive when moving.

The pulverizer disclosed in Utility Model Registration No. 2565965 has solved the above-mentioned problem.
However, the opening / closing lid 93b is of a manual type, so that the opening of the fixed hopper 92a is not closed unless it is intentionally operated. Even when the movable hopper 92b is in the retracted state, the opening / closing lid 93b is forgotten to be closed and fixed. There is a concern that the opening of the hopper section 91b remains open.

Normally, a feed roller for feeding an object to be crushed into a crusher is provided at the base of the hopper, and when the hopper is moved as disclosed in Japanese Utility Model Registration No. 2565965. In the case of a split type in the middle for storing, etc., the feed roller is exposed at the time of storage, and if the crushed material is inadvertently stored in the stored state,
Since the number of guide portions is small, there is a concern that the crushed object may jump or that clothes or the like of an operator may be bitten by the feed roller.

The present invention has been made in view of the above problems, and has a configuration in which the front end side can be stored by being divided at appropriate positions, and the opening of the hopper is securely covered with a safety guard in the stored state. It is an object of the present invention to provide a safe and easy-to-use crusher for trees and the like having a shredder hopper and / or a chipper hopper.

[0009]

Means for Solving the Problems, Functions and Effects In order to achieve the above-mentioned object, a first aspect of the present invention provides a method for manufacturing
A shredder for crushing the input branches and / or a crusher equipped with a chipper for cutting and crushing the input branches is provided, and a shredder hopper for inputting the branches and leaves is attached to the shredder of the crusher, and crushing is performed. A chipper hopper for feeding a branch tree is attached to a chipper of the apparatus, and the shredder hopper and / or the chipper hopper are attached to the shredder and / or the chipper, respectively. In a crusher such as a tree having a retractable portion attached to be openable and closable in a manner such that the respective retractable portions are operated to the retracted state and are deployed so as to cover the openings of the respective base end portions, A retractable hood provided with a storage safety guard stored outside the shredder hopper and / or the chipper hopper in conjunction with the operation of each storable portion to the operating state. Is a tree like grinder having a path.

According to the above configuration, when the crusher is not operating, the hopper can be stored to reduce the area of the crusher, which does not hinder the work in the vicinity, and is easy to carry. In addition, by simply operating the hopper storage section to the storage state or the operating state, the storage safety gart can be expanded or stored, and the base end opening of the hopper in the storage state can be securely covered with the safety guard. As a result, the crushed object is not accidentally thrown in while the hopper is in the stored state, so that the operation is easy and the usability is good. Also, during operation, the storage safety guard is stored outside the hopper, so that the object to be ground can be smoothly fed into the hopper.

According to a second aspect of the present invention, based on the configuration of the first aspect, a tree or the like having a retractable hopper is characterized in that each storage safety guard has a locking function in a retracted state of each storable portion when deployed. It is a crusher.

According to the above construction, in addition to the operation and effect of the first invention, the storage safety gart is deployed in conjunction with the operation of the hopper in the storage state in the storage state, and the hopper is locked in the storage state. The operation is easier because it is possible.
