Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a gravel discharging device for a dump truck that allows only one person who uses a unicycle to perform the gravel discharging operation without an operator on the platform. A discharge port 1D is formed in a central portion of a case 1A arranged on a rear wall portion of a loading platform 2A of a dump truck 2, and a lid 1D1 is provided on the discharge port 1D so as to be openable and closable. A right-handed screw 1B is rotatably installed inside 1A, and a left-handed screw 1C is installed rotatably at a right position.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gravel discharging device in a dump truck.

[0002]

[Prior Art]

 Conventionally, this kind of thing is as follows. One to three workers were on the platform to scoop the gravel onto the unicycle.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. The work of discharging gravel with a scoop into a unicycle was a great effort. Moreover, when dumping the loading platform, all the gravel will fall by the loading platform width.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the case of the present application, the case 1A arranged on the rear wall portion of the loading platform 2A of the dump truck 2 includes a rear wall portion 1A1 configured to correspond to the rear wall portion of the loading platform 2A, and the rear surface of this rear wall portion. It is composed of a cylindrical screw case portion 1A2 that is continuously installed on the rear side wall and side wall portions 1A3 that are stretched to the left and right of this screw case portion. The rear wall portion 1A1 has openings to the left and right except for the central portion 1A11. 1A 12, 1A13 are formed, an outlet 1D is formed in the central portion of the screw case portion 1A2, and a lid 1D1 is provided on the outlet 1D so as to be openable and closable to the left in the case 1A. Gravel discharging device for a dump truck in which a right-handed screw 1B is rotatably installed in a position and a left-handed screw 1C is rotatably installed in a right orientation. A.

【Example】

 Examples will be described with reference to the drawings. 1 is a gravel discharging device in the dump truck of the present invention. Reference numeral 2 is a known dump truck, the rear wall portion of the loading platform 2A is removed, and the gravel discharging device 1 is disposed in this portion.

Therefore, the gravel discharging device 1 is composed of a case 1A, left and right screws 1B and 1C rotatably arranged in the case, and a discharging port 1D. The case 1A includes a rear wall portion 1A1 configured to correspond to the rear wall portion of the luggage carrier 2A, a cylindrical screw case portion 1A2 continuously provided on the rear surface of the rear wall portion, and left and right sides of the screw case portion. The rear wall portion 1A1 is formed with a side wall portion 1A3 stretched, and openings 1A12 and 1A13 are formed on the left and right sides except the central portion 1A11.

Further, the screw case portion 1A2 has a discharge port 1D formed in the center thereof, and the discharge port 1D is provided with a lid 1D1 which can be opened and closed. In the case 1A thus configured, a right-handed screw 1B is rotatably installed at the left position and a left-handed screw 1C is rotatably installed at the right position. Reference numeral 1E is a shaft of these screws, and is connected to an engine 1F arranged on the upper surface of the case 1A via a speed reducer 1G, a chain 1H, a sprocket 1I, and the like.

Reference numeral 1J is an engine mounting frame provided on the case 1A, and 1J1 is a fixing plate of the engine mounting frame. The case 1A is attached to the loading platform 2A of the dump truck 2 with a support arm 1K above and a connecting pin 1K1 below. Therefore, by pulling out the pin 1K1 of the support arm 1K and pulling out the connecting pin 1L, the case 1A can be removed from the platform 2A of the dump truck 2.

The present invention operates as follows. 1) Dump the loading platform 2A of the dump truck 2 equipped with the gravel 3 a little. 2) Open the lid 1D1 of the discharge port 1D, and arrange the known unicycle 4 below the discharge port. 3) When the right-handed screw 1B and the left-handed screw 1C are rotated, the gravel 3 is conveyed toward the discharge port, and is dropped and stored in the unicycle from this discharge port.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. 1) There is no need for a worker to ride on the platform, and only one person using a unicycle can work. 2) Even if the cargo bed is dumped, the gravel will drop at one discharge port, preventing the entire gravel from falling. 3) Since the artificial work time can be changed to the mechanical work time, the labor can be significantly reduced and the work time can be significantly reduced. 4) The labor shortage can be compensated and the labor cost can be significantly reduced.

Further, the screw case portion 1A2 is provided with a discharge port 1D at a central portion thereof, and the discharge port 1D is provided with a lid 1D1 which can be opened and closed. In the case 1A thus configured, a right-handed screw 1B is rotatably installed at the left position and a left-handed screw 1C is rotatably installed at the right position. Reference numeral 1E is a shaft of these screws, and is connected to an engine 1F arranged on the upper surface of the case 1A via a speed reducer 1G, a chain 1H, a sprocket 1I and the like. Incidentally, the hydraulic motor instead of the engine, electric motor, it is the other power and child.

Reference numeral 1J is an engine mounting frame provided in the case 1A, and 1J 1 is a fixing plate of the engine mounting frame. The case 1A is attached to the loading platform 2A of the dump truck 2 with a support arm 1K above and a connecting pin 1K1 below. Therefore, by pulling out the pin 1K1 of the support arm 1K and pulling out the connecting pin 1L, the case 1A can be removed from the platform 2A of the dump truck 2. Although the above description is based on the assumption that gravel is used, it is natural that it can be used for volcanic ash, crushed stone, sand, asphalt mixture, and cement mixture.
