Abstract

PURPOSE:To simply adjust the height of a driving wheel and the width between wheels and improve travel performance by making the driving wheel adjustable vertically by an adjusting device and making it movable in the right and left direction together with the adjusting device. CONSTITUTION:When a pin 20 inserted into the coupling hole 18 of a shaft tube 15 fitted to the bearing section 14 of a chain case 13 and into one of multiple coupling holes 19 of a driving shaft 17 protruding from a mission case 16 is pulled out, the shaft tube 15 is made slidable against the driving shaft 17. A slidable fitting shaft 26 fitted with the height adjusting shaft 23 of the chain case 13 is slidably inserted into the shaft tube 25 of a frame 24. Therefore, when the chain case 13 is pushed or pulled together with a driving wheel 11, the shaft tube 15 and slidable fitting shaft 26 slide, thus the width between the driving wheel can be adjusted. On the other hand, the height of the wheel 11 can be adjusted by adjusting a positioning nut 28 screwed into the screw section 27 of the height adjusting shaft 23.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an adjustment device for harvester wheels.

Harvesters equipped with wheels were known.

(Problems to be Solved by the Invention) However, in the above-mentioned known device, the wheel width of the drive wheel could not be adjusted to match the ridge width, so it was inconvenient to handle.

(Means for Solving the Problem) Therefore, the present invention provides a weeding body 6, a grain culm pulling device 7, a cutting blade 8, etc. on the front side of a machine body l having an engine 2, a fuel tank 3, a walking control handle 5, etc. A reaping device 5 is provided, and a pair of drive wheels 11 are provided on both the left and right sides of the machine body l. This is an adjustment device for the wheels of a harvester, which is provided so that its movement can be adjusted in different directions.

(Configuration) An embodiment of the present invention will be described with reference to the drawings. l is the body of a harvester, and the body l includes an engine 2, a fuel tank 3,
You can see the walking control handle 4, etc. In addition, a reaping device 5 is provided on the front side of the machine 1, an early fall weeding device 6 is provided at the leading edge of the reaping device 5, and a grain culm pulling device 7 is provided behind the weeding device 6.
will be established. 8 is a cutting blade for reaping grain culms in the field; 9 is a height adjustment wheel for adjusting the cutting height of the reaping device 5; and 10 is an operating lever for operating the height adjustment heavy wheel 9.

A pair of drives 14111 are provided on both left and right sides of the body l. The drive wheels 11 are mounted on shafts 12 at the lower portions of left and right chain cases 13, respectively. A bearing part 14 is provided at the -L portion of the chain case 13, and a horizontal shaft cylinder 15 that projects inward can be attached to the bearing part 14. The shaft cylinder 15
Insert the drive shaft 17 protruding from the mission case 16 of the fuselage l. An engagement hole 18 is formed in the shaft cylinder 15, and a plurality of engagement holes 19 are formed in the drive shaft 17 in the axial direction, and either the engagement hole 18 or the engagement hole 19 is selectively matched with each other to secure the pin. 20 and fix it. That is, chain case 1
3, the drive wheel 11 is attached to the transmission case 16 so as to be movable in the left and right direction, and the width of the drive wheel 11 is adjusted. The engagement hole 18 of the shaft cylinder 15 is aligned with the engagement hole 19 by sliding in and out in the direction and fixed with the pin 20, and the drive wheel 11 is moved step by step. The drive wheels 11 are each individually adjustable in movement.

A bearing plate 21 is provided at the rear of the chain case 13.

A shaft 22 in the left and right direction is rotatably attached to the bearing plate 21,
The shaft 22 has a height adjustment shaft 2 in the front-rear direction that projects rearward.
Fix the front end of 3.

The front end of a frame 24 is fixed to the rear part of the mission case 16, and the left and right shaft cylinders 2 are attached to the rear end of the frame 24.
Install 5. The shaft cylinder 25 has a sliding mounting shaft 26 for left and right force directions.
is slidably inserted from the outside, and the screw portion 27 at the rear end of the height adjustment shaft 23 is loosely fitted into the outer end of the sliding mounting shaft 26 so as to be slidable back and forth. A positioning nut 28 is attached to the screw portion 27.
screw together. The positioning nut I/28 is the height adjustment shaft 2
Prevent 3 from moving backward 11-.

29 is a focusing device.

(effect) Next, the action will be described.

Since the present invention has the configuration described in -, the engagement hole 1 of the shaft cylinder 15 installed in the bearing part 14 of the chain case 13 is
8 and a drive shaft 17 protruding from the mission case 16.
When the pin 20 inserted into any one of the plurality of retaining holes 19 is removed, the shaft cylinder 15 becomes slidable in and out of the drive shaft 17. Furthermore, since the sliding mounting shaft 26 to which the height adjustment shaft 23 of the chain case 13 is attached is slidably inserted into the shaft tube 25 of the frame 24 from the beginning, the chain case 13 can be mounted together with the drive wheel 11. When pushed and pulled inward and outward, the shaft cylinder 15 and sliding mounting shaft 26 slide,
The drive wheels 11 can be moved.

In this state, when the engagement hole 18 of the shaft tube 15 is aligned with the other retaining hole 19 and the bin 20 is inserted, the width of the drive wheel 11 is adjusted to the ridge width of the field.

Thus, the screw portion 27 at the rear end of the height adjustment shaft 23 is loosely fitted to the outer end of the sliding mounting shaft 26 so as to be slidable back and forth.
is rotatably attached to the bearing plate 21 at the rear of the chain case 13, and a positioning nut 28 is screwed into the threaded portion 27 at the rear end of the height adjustment shaft 23, so that it can be easily adjusted against the slope of the field. , this is adjusted using the locating nut 28.

Then, when the engine 2 is started and the machine moves forward while supporting it with the walking control handle 4, the reaping device 5
The weeding body 6 separates the grain culms in the field, the separated grain culms are raised by the grain culm pulling device 7, are harvested by the cutting blade 8, and the concentrator 29
Focus by.

(Effects) As mentioned above, conventionally, a reaping device consisting of a grass cutting body, a grain culm pulling device, a cutting blade, etc. is provided on the front side of a machine body having an engine, a fuel tank, a walking steering handle, etc. Harvesters were known which were equipped with a pair of drive wheels. However, in the known method, the width of the drive wheel could not be adjusted to match the width of the ridges, so it was inconvenient to handle.

However, in the present invention, a reaping device 5 consisting of a weeding body 6, a grain culm pulling device 7, a cutting blade 8, etc. is provided on the front side of a machine body l having an engine 2, a fuel tank 3, a walking control handle 5, etc.
A pair of driving wheels 11 are provided on both left and right sides of the aircraft body 1, and the driving wheels 11 are formed to be adjustable vertically by an adjusting device, and the driving wheels 11 are movable and adjustable in the horizontal direction together with the adjusting device. Since it is used as an adjustment device for the machine's wheels, a. The wheels can be adjusted by adjusting the ridge height.

Wheel width can be adjusted by adjusting the mouth and ridge width.

C. It is easy to adjust.

This effect is achieved.
