Abstract

PURPOSE:To prevent accumulation of grains at the connecting section by making the outer diameter of a carrier in a coreless coil form greater than the outer diameter of the spiral vane of an auger provided within a grain hopper, and thereby arranging the spiral vane which is made greater than the spiral vane of the auger in diameter, at the connecting section between the starting section of the carrier and the end section of the auger. CONSTITUTION:The starting section 30 of the carrier 3 in a coil form of a grain conveyor (a) which takes over grains from the end section of an auger 4, feeds grains in the grain flow accelerated by the spiral vane 41' of a large diameter in a considably long range in the carrying direction so that the grains are taken over smoothly. Since the outer diameter R3 of the carrier 3 is made greater than the outer diameter R2 of the spiral vane 41 of the auger 4, the feeding capability of the carrier 3 is enhanced. By this constitution, the grains taken over by the carrier 3 can be delivered without being accumulated at the connecting section between the auger 4 and the carrier 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a grain transport vehicle having a grain hopper mounted on the bed of a truck, in which grains are delivered to a desired location from a discharge port provided at the bottom of the grain hopper. The present invention relates to an improvement in a grain discharging device configured by connecting a flexible grain conveyor to its discharge port so as to transport the grains.

The grain discharging device in the above-mentioned grain transport vehicle usually has a first
As shown in the figure, in a grain transport vehicle A having a grain hopper 1 mounted on the loading platform of a truck T, a discharge port is installed at the bottom of a machine wall 10 of the grain hopper 1. 11
A connecting cylinder part 12 having a mounting collar part 120 is installed in the connecting cylinder part 12, and a transporting body 3 in which a steel wire or the like is wound in a coreless coil shape inside a flexible transporting cylinder 2 is rotatably attached to the connecting cylinder part 12. The grain conveyor a, which is stored in a grain conveyor a, has its transport tube 2 whose end is closed to the mounting flange 120, and whose spiral transport body 3 wound in a coreless coil is connected to the grain hopper. The spiral conveying body 3 is connected to the outer end of the rotating shaft 40 of an auger 4 for discharging grains, which is horizontally arranged at the bottom of the inside of the auger 1.
rotates, and the grains carried out to the discharge port 11 by the auger 4 are received in the conveying cylinder 2 of the grain conveyor a, and then transferred to the conveying cylinder by the rotating spiral conveying body 3 in the shape of a coreless coil. 2
The material is configured to be transported toward a discharge port opened at the other end.

This means that the grain transport vehicle A of the above-mentioned form transports raw grains harvested by a harvester such as a combine harvester in the field to a workhouse where a grain dryer is installed or to a grain drying facility. When transporting grain to a work building or facility and discharging it, the position where the grain transport vehicle A stops is set at the reception port of the installed grain dryer. Normally, the grain transport vehicle A is parked at an appropriate location, and the grain conveyor A connected to the outlet 11 of the grain dumper 1 is used for positioning. For simplicity and ease of operation, the aforementioned grain conveyor a connected to the outlet 11 of the grain hopper 1 is
This is because the conveying tube 2 has a so-called spring-contact configuration in which it can be freely bent.

From this, as mentioned above, the conveyor 3 in which steel wire or the like is wound in a coreless coil is attached to the terminal end of the grain discharge auger 4 facing the discharge port 11 of the grain dumper 1. In the grain discharging device of the grain transport vehicle A, which is constructed by connecting the grain conveyor a stored in the flexible transport tube 2, the grain conveyor a is connected to the terminal end of the spiral blade 41 of the auger 4. By connecting the starting end of the conveyor 3, which is made of a coiled steel wire, etc., the grains are not received smoothly at this connection site, and the connection site may become clogged with grains. There are some problems that can easily occur.

The present invention has been made in order to solve this problem, and includes an outlet 11 of the grain hopper 1 of the grain transport vehicle A.
A grain conveyor a is connected to a flexible transport cylinder 2 in which a transport body 3 made of a coreless coil of steel wire or the like is rotatably stored, and the grains in the grain hopper 1 are discharged. When the grain conveyor a is
and the spiral blade 41 of the auger 4 in the grain hopper 1
It is an object of the present invention to provide a new means that can prevent grain from clogging at the connection site with the terminal end of the grain.

Therefore, the present invention was completed based on knowledge obtained through various studies and experiments in order to solve the above-mentioned problems. In other words, since the conveyor 3 wound in a coreless coil of steel wire or the like has a small conveyance area, the conveyor 3 wound in a coil with the same diameter as the helical blade 41 of the auger 4 has a small conveyance area. It was found that the grain feeding capacity is lower than that of the spiral blade 41, and that the grain feeding capacity can be increased by increasing the outer diameter of the coiled blade. Although the ability to scrape out and send out the grains is small due to the small size of the grain, it has been found that the grains that have flowed out and are transported smoothly. 3, spiral BK4 with outer diameter of auger 4
The spiral blade 41 of the auger 4 has a larger diameter than that of the auger 4.
When the grains sent out were sent to the starting end 30 of the coreless coil-shaped conveyor 3 by increasing the flow velocity with a spiral blade having a larger diameter than the spiral blade 41, clogging occurred at the connecting part. This is due to the fact that it was possible to smoothly discharge the grains without constricting them, and from this,
In the present invention, a conveying body made of a coreless coil of steel wire is placed inside a flexible conveying cylinder at the outlet provided at the bottom of the wall of a grain hopper mounted on the bed of a truck. The starting end side of the conveying tube of the grain conveyor rotatably stored in the grain conveyor is connected, and the starting end side of the coreless coil-shaped conveying body of the grain conveyor is placed horizontally at the bottom of the grain hopper. In a grain discharging device for a grain transport vehicle, which is connected to a terminal end of a helical blade of a grain discharging auger which is supported on a shaft and whose terminal end faces a discharge port, the above-mentioned coreless coil-shaped transport The outer diameter of the body is larger than the outer diameter of the spiral blade of the auger provided in the grain hopper, and at the connection site between the starting end of the coreless coil-shaped conveying body and the terminal end of the auger, This invention proposes a grain discharging device for a grain transport vehicle, which is provided with a spiral blade having a diameter larger than the outer diameter of the spiral blade of the auger.

In the grain discharging device, the outer diameter of the coreless coil-shaped conveyor is larger than the outer diameter of the helical blade of an auger provided in the grain hopper, and the coreless coil-shaped conveyor is Since the helical blade, which has a diameter larger than the outer diameter of the auger's helical blade, is disposed at the connection point between the starting end of the body and the auger's terminal end, the auger's end and the grain are connected to each other. Grain transfer at the connection point with the starting end of the coil-shaped transport body of the grain conveyor is accelerated by the large-diameter spiral blades installed at the connection point, and the flow of grains sent out is accelerated.
