Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to improvements in grain conveying machines such as throwers.

[Conventional technology and its issues]

Conventionally, grain conveying machines have been common in which a hopper is attached to one side of a thrower case and grains are fed into the hopper.
A large amount of intake air is required to transport grain by lifting it up. Therefore, since it was not possible to provide an intake hole in the thrower case on the side where the hopper is attached, an intake hole was provided in the center of the thrower case on the opposite side to the side where the hopper is attached, and the shaft of the rotor was protruded from the center of the thrower case on this side, a pulley was attached to the shaft of the rotor, and it was connected to a separately installed motor by a belt.

Grain conveyors such as thrower cases having such a structure have the following problems.

(a) The thrower case must be firmly fixed to the underframe.

(b) A frame is required to install and secure the motor.

(c) Exposed belts are dangerous, so a structure that protects them with a cover is required.

(d) It requires a large installation area and a large number of parts, resulting in high costs.

The purpose of this invention is to rationally solve the problems of the conventional technology by directly connecting the rotor to the motor shaft and attaching the thrower case to the motor, and to provide a transport machine with excellent lifting and transport efficiency at a low cost. It is something to do.

[Means to solve the problem]

The configuration of the present invention, which solves the problems of the prior art, is to mount and support the motor on a support stand provided on one side of the underframe, attach a thrower to the motor, and attach the rotary blades that make up the thrower to the shaft of the motor. The hopper is connected directly to the opposite side of the thrower attached to the motor, and the inclined lower end of the grain dispensing tube of the hopper attached to the underframe is connected to the opposite side of the thrower attached to the motor, and the amount of grain supplied to the hopper is adjusted. The present invention is characterized in that an adjustment plate for guiding grains to the bottom surface of the grain threshing tube is slidably provided obliquely, and the upper surface of the grain threshing tube is constructed of an air intake plate member.

〔Example〕

Next, details of embodiments of the present invention will be explained with reference to the drawings.

FIG. 1 is a partially cutaway side view, and FIG. 2 is a plan view of the same.

1 is an underframe, and on one side of this underframe 1 is a support stand 2.
is fixed, and a motor 3 is mounted and supported on the support base 2. A rotary blade 5 constituting the thrower A is directly connected to the rotating shaft 4 of the motor 3, and one side wall portion of a thrower case 6 that accommodates the rotary blade 5 is fixed to the motor 3 via a motor metal 7. has been done. 8 in the figure is a grain barrel.

Reference numeral 9 denotes a case lid that is removably attached to the thrower case 6 on the side opposite to the mounting side of the motor 3 using a stopper 20, and approximately in the center of this case lid 9 is a grain threshing barrel of a hopper, which will be described later. A window 10 is formed into which the discharge end is inserted. Reference numeral 11 denotes a hopper having a rectangular planar shape supported on the underframe 1 via a mounting support rod 12.The hopper 11 has a hopper on the inside upper part thereof that is inclined downwardly toward the thrower A direction. A grain receiving plate 14 is attached which forms a grain gap 13 between the inner surface of the hopper 11 and the grain receiving plate 14.
This is to control the flow rate of grain that is introduced from the top of the pipe. Reference numeral 15 denotes an adjusting plate for controlling the amount of grain flowing, which is disposed below the grain receiving plate 14 provided on the hopper 11. Tilt downward in the opposite direction,
The grain gap 16 between the inclined lower end of the adjusting plate 15 and the inner surface of the hopper 11 is adjusted in size to adjust the actual amount of grain supplied to the thrower A.

Reference numeral 17 denotes a grain shovel attached to the lower end of the hopper 11, tilted downward in the direction of the thrower A, and having its lower end inserted into the window 10 of the case lid 9 constituting the thrower case 6. . The cross-sectional shape of the grain threshing tube 17 is made rectangular, and a wire mesh 18 is stretched over the upper surface of the grain threshing tube 17, so that the air necessary for transporting the grains by the thrower case A can be supplied. This is what I did. Of course, the mesh size of the wire mesh 18 should be so large that the grains to be fried will not pass through. You may also use a punch plate. In the figure, reference numeral 19 denotes a grain feeder such as a belt conveyor that continuously feeds grains into the hopper 11.

[Explanation of action]

Next, to explain the operation based on the above embodiment, the grains continuously fed by the belt conveyor 19 are fed falling onto the grain receiving plate 14 as shown by the chain line in FIG. The grain is fed onto the adjustment plate 15 with its flow velocity relaxed, and the grain whose flow rate is adjusted by the grain flow gap 16 flows down from the lower part of the hopper 11 along the slope of the bottom plate of the grain distribution tube 17 to the thrower A. The grains are then lifted up and conveyed along the grain lifting tube 8 by the lifting action of the rotary blades 5 and the wind action caused by the intake of air from the wire mesh 18. For example, this machine is used to transport and supply paddy dried by a paddy dryer to another working machine, such as a paddy pounding machine.

[Effect of idea]

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) The thrower and motor are integrated by attaching the thrower case to the motor and directly connecting the rotor blades to the motor shaft, so the thrower can be installed on the underframe by attaching the motor support to the underframe, which is easier than before. The installation area is smaller compared to technology, and
Since the number of parts is small, it is suitable for low-cost mass production.

(b) The suction plate member formed on the top surface of the grain feeding tube is not blocked by the grains supplied downstream;
Efficient wind lift transport using the thrower.

(c) The amount of grains flowing down can be adjusted by the adjustment plate, and since the grains are guided toward the bottom of the grain tray, the blocking effect of the intake plate member can be further prevented.
