Description

[Detailed explanation of the invention] (Industrial application field) This invention is an attachment that is detachably attached to a front loader of an agricultural tractor, and is particularly useful for handling bulky grass, corn, or snow. This relates to buckets used for loading, dumping, etc.

(Prior Art) Conventionally, when it was desired to load and transport a large amount of cargo in a bucket, the shape of the bucket was made larger to increase its capacity.

(Problems to be solved by the invention) However, when the shape of the bucket is made large, the following disadvantages occur.

a The dumping angle of the bucket is insufficient, making it difficult to release.

b Dumping clearance is insufficient during bucket dumping. For example, it becomes difficult to discharge onto a truck bed.

c. Furthermore, since a heavy load is applied to the bucket cart during dumping, a shock may occur when the bucket cart rotates toward the dumping side, which is dangerous.

The purpose of this invention is to solve the above problems and increase the capacity of the bucket.

(Means for solving the problem) In order to achieve the above purpose, this invention has the following configuration.

The bucket is provided with a bottom plate that opens and closes around an axis perpendicular to the longitudinal direction of the front loader.

Further, the bucket bag is provided with a shock absorber for connecting the bucket bag and the bottom plate, and a locking means for locking and releasing the bottom plate from the bucket bag.

(Structure and operation of embodiments) This invention will be described below based on illustrated embodiments.

Reference numeral 1 is a bucket bag, and except for a bottom plate 7 to be described later, a wire mesh 3 is attached to a frame 2, and the entire bag is shaped like a box. 4 is a rear wall on the front loader 22 side, and 5 is a front wall opposite to the rear wall 4. The rear wall 4 is higher than the front wall 5 and is formed to be inclined forward and upward.

Reference numeral 6 denotes a mounting plate fixed to the frame 2a on the rear wall 4 side, and is configured so that the bucket 1 can be detachably attached to the tip of the lift arm 23 of the front loader 22 by means of a pin.

Reference numeral 7 denotes a bottom plate that can be opened and closed, and is rotatably supported by a support shaft 9 on a pair of left and right brackets 8 whose bases on the front wall 5 side are attached to the frame 2b of the front wall 5.

A pair of left and right shock absorbers 10 connect the bottom frame 2c and the bottom plate 7.

A hook 11 is rotatably attached to a bracket 12 fixed to the rear wall frame 2a by a pin 13, and is used to lock and release the rear end of the bottom plate 7. 14 is a return spring. This hook 11 is adapted to be operated by the driver via a wire 15 connected thereto.

The locking means may be replaced by the hook as shown in FIG.
Reference numeral 16 denotes a locking pin which is loosely fitted into a hole formed through the rear wall frame 2a and is constantly pressed toward the bottom plate 7 by a spring 18 attached to this pin 16 between the mounting bracket 17 and the rear wall frame 2a. Reference numeral 19 denotes a pin hole recessed in the rear end of the bottom plate 7. Therefore, when the bottom plate 7 is closed, the pin 16 is pressed by the spring 18 and fits into the pin hole 19, supporting the bottom plate 7. To release the bottom plate 7, the wire 15 connected to the pin 16 is simply pulled.

Further, depending on the use of the bucket bag 1, the opening and closing direction of the bottom plate 1 can be reversed from the above-described embodiment, and the bottom plate 1 can be opened and closed with the rear wall 4 side as an axis.

Next, the effect will be explained.

When loading bulky cargo W such as grass,
As shown in FIG. 6, for easy loading from a harvester 31 connected to an agricultural tractor 21,
The lift arm 23 is raised and the bucket tote 1 with the bottom plate 7 closed is tilted so that the front wall 5 side of the bottom plate 7 is higher. If the rear wall 4 is made higher than the front wall 5 as in the embodiment, the center of gravity of the bucket 1 is on the front loader 22 side when the load W is loaded, so the bucket 1 is stable.

Dumping of the load W is carried out using the wire 15 as shown in FIG.
Pull to release the hook 11. At this time, since the bucket 1 and the bottom plate 7 are connected by the shock absorber 10, the bottom plate 7 does not open suddenly.

To close the bottom plate 7, as shown in FIG. Loosen to lock the hook 11 to the bottom plate 1. Alternatively, when the bottom plate 7 rotates toward the rear wall 4, the bottom plate 7 pulls down the hook 11, thereby automatically closing. The closure of the bottom plate 7 also
Due to the shock absorber 10, this is not done suddenly.

(Effects) The effects of this invention are listed below.

(1) Since the bottom plate can be opened and closed, the capacity of the bucket can be increased, and the dumping clearance is also large, making it easy to load onto the loading platform of a truck.

(2) If the back wall of the bucket is made higher than the front wall,
The center of gravity of the loaded bucket is on the lift arm side, providing good stability.

In addition, with the lift arm raised, it can be shot from the rear work equipment such as a harvester or snow blower, so one person can work on it.

(3) When the bottom plate of the bucket is opened and closed, the shock absorber operates and there is no impact, so the load will not fly off or be damaged.

(4) Since the bottom plate is opened and closed slowly by the shock absorber, there is no risk of damage even if it interferes with the loading platform of the truck, and it is safe because the bottom plate does not wobble. Furthermore, the tractor does not shake much and there is no risk of it falling over.

(5) Since the bottom plate is closed with the lift arm raised, the operator can confirm the status of the bucket, and if the load is feed such as grass or corn, the feed will not be contaminated with soil.

(6) No hydraulic equipment is required to open and close the bottom plate, and the structure is simple and can be provided at low cost.
