Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tractor-mounted wagon device.

(Prior art) As a harvesting machine for maize, forage, etc., a harvesting device is attached to the rear part (in the front part in the direction of work progress) of a tractor that can move forward and backward, and a wagon for storing harvested products is mounted on the front bonnet. Some wagons are equipped with a wagon or the wagon is pulled by a tractor.

(Problems to be Solved by the Invention) When a wagon is mounted on the bonnet of a tractor, there is a problem in that a sufficient capacity of the wagon cannot be secured due to the bonnet.

In addition, the tractor-pulled type had problems with turning performance, and moreover, the overall longitudinal length was large.

The present invention aims to solve these problems.

(Means for Solving the Problems) In order to solve the problems of the conventional art, the technical means taken by the present invention are characterized by the fact that the steering wheels 9 and the driving 2 with a ring 10
A tractor-mounted type tractor is equipped with a harvesting device 15 at the front of an axle-wheel type tractor 1 in the direction of work progress, and a wagon 21 for storing the harvested material released from the harvesting device 15 is provided at the rear side of the tractor 1 in the direction of work progress. In the wagon device, the steering wheel 9 on the side of the wagon 21 is connected to the harvesting device 1.
A support frame 27 is attached to the tractor body 5 at an intermediate portion in the front-rear direction with the drive wheel 10 on the 5 side, and the mounting machine frame 23 of the wagon 21 connected to the support frame 27 is extended rearward in the work progress direction. The wagon 21 is mounted on a machine frame 23, and the machine frame 23 has caster wheels 26 near the steering wheel 9, and furthermore, the wagon 21 is mounted on the tractor bonnet 7 provided on the steering wheel 9 side. To provide a tractor-mounted wagon device characterized in that the front end portions of a wagon 21 mounted on a frame 23 on the side in the work progress direction are overlapped in the front-rear direction.

(Function) The harvested material from the chute 19 of the harvesting device 15 is put into the wagon 21 and stored therein, but the weight of the harvested material is not only supported by the steering wheels 9 and drive wheels 10 of the tractor 1; Steering wheel 9 of tractor 1
and a caster wheel 26 provided with a wagon frame 23.
Wagon 21 is also supported by
It is possible to increase the load capacity of the vehicle.

Furthermore, since the caster wheels 26 are provided as wagon wheels near the steering wheels 9 of the tractor 1, the turning performance and steering performance of the tractor 1 are improved, making driving easier for the operator.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The tractor 1 is a two-axle wheel type having a front wheel 9 as a steering wheel and a rear wheel 10 as a driving wheel, and in this example, it is a four-wheel type.

The tractor body 5 of the tractor 1 includes an engine 2, a transmission case 3, a front axle frame 4 protruding forward from the engine 2, and the like.

A pair of left and right vertical frames 6 are erected in the center of the tractor body 5 in the longitudinal direction. It is installed.

The rear side of the vertical frame 6 is a control section 8, and the seat 11 and handle 12 of the control section 8 can be freely changed between a forward position (imaginary line in Fig. 1) and a rearward position. It is said to be a dual-use type that can be switched freely.

In addition, in the case of harvesting work, since the seat 11 and handle 12 in the control section 8 are in the solid line state in Figure 1, they will be referred to as the front part (front) or rear part (backward) hereinafter based on the direction of work progress. .

A harvesting device 15 such as a maize harvester is attached to the front part of the tractor 1 via a three-point link so as to be movable up and down.

This harvesting device 15 has a cutting section 1 in front of a blower 16.
7 and a divider 18, and a chute 19 is provided on the upper part of the chute 19, and this chute 19 extends above the eaves part 13 so that the harvested product can be thrown into a wagon 21 disposed on the upper part of the bonnet 7. has been done.

The wagon device 22 is disposed on the rear side of the tractor 1 in the direction of work progress, and the wagon device 22 is attached to a machine frame 23 and an upper end of a support 25 projecting upward from the rear of the machine frame 23 via a horizontal shaft 24. The wagon 21 is rotatably supported and is disposed astride the bonnet 7 so that the front end side of the wagon 21 overlaps the bonnet 7 in the front-rear direction.

The machine frame 23 has a pair of left and right caster wheels 2 at the rear lower part.
6, the caster wheels 26 of which are located close to the steering wheels 9 of the tractor 1.

Further, the machine frame 23 is located at the front of the tractor body 5 at a longitudinally intermediate portion thereof, that is, the steering wheel 9 and the driving wheel 10.
It has a connecting portion 28 that is connected to a pair of left and right support frames 27 fixed between the The wagon device 22 is removably connected to the tractor 1 so as to be vertically rotatable about a horizontal axis.

The wagon 21 has a frame made of a rod frame, and is formed by attaching netting or plate materials to the peripheral side surfaces and the bottom surface, and the bottom surface is placed on the bottom of the machine frame 23.

The bottom of the wagon 21 is the front bottom 4 midway in the width direction.
0 is a raised bottom higher than the rear bottom part 41, and the lower part thereof is a fitting part 42 which is open forward and downward, and the bottom surface of this fitting part 42 is mounted on the bottom of the machine frame 23. In this state, it can be fitted to the front upper part of the bonnet 7 (rear upper part in the working direction) with a gap therebetween. Although the entire width of the front bottom portion 40 may be made into a raised bottom, it is better to make it bifurcated as shown in FIG. It is large and desirable.

The rear part of the wagon 21 has a low rear bottom part 41, so it is the place where a large amount of harvested material is stored and is the heaviest part.
6 is placed. This caster wheel 26 is 1
A wheel may be used, but two wheels are preferable.

Reference numeral 31 denotes a hydraulic cylinder for lifting and lowering the wagon, which is pivotally connected to the upper part of the wagon 21 side and the bottom of the machine frame 23. Reference numeral 32 denotes a tilt mechanism disposed above the discharge port A at the rear upper part of the wagon 21, and is supported by one end of a pair of left and right swinging rods 33. One end of the link 35 is connected to the other end, and the other end of the link 35 is pivotally supported to the support 25 of the machine frame 23, and the swing rod 33, the link 35, etc. A link mechanism 36 that operates the tilt 32 is formed by this.

When the wagon 21 is rotated upward by the operation of the hydraulic cylinder 31, the tilt 32 is shifted from the discharge port A rear shielding position (working position) shown in FIG. 1 to the upward retracting position shown in FIG.

(Effects of the invention) In the present invention, since the connecting portion 28 of the machine frame 23 on which the wagon 21 is mounted and the tractor 1 is located at the intermediate portion in the longitudinal direction between the steering wheel 9 and the drive wheel 10 of the tractor 1, the wagon 21 The weight of the harvested crops is also borne by the steering wheels 9 and the driving wheels 10, so there is no problem even if the amount of cargo is increased.

Since the wagon 21 is partially overlapped with the bonnet 7 of the tractor 1 in the longitudinal direction, even if the wagon 21 is constructed with a large capacity as described above, the overall longitudinal length does not become much larger.

Further, the machine frame 23 on which the wagon 21 is mounted is equipped with caster wheels 26, and since the caster wheels 26 are located near the steering wheels 9 of the tractor 1, the steering performance of the tractor 1 can be fully demonstrated. Not only can the turning performance be improved without impairing the turning performance, but also the caster wheels 26
Because it can bear the weight of cargo,
You can increase your harvest capacity.
