Description

It relates to a paddy field working machine that efficiently and surely performs paddy field work after transplanting seedlings.

Conventionally, in order to remove weeds growing around a plurality of seedlings planted in a paddy field, a weeding machine for weeding between the rows of seedlings is attached to a paddy field working machine to perform weeding. A conventional paddy weeder is described in, for example, Patent Document 1.

In the weeder described in Patent Document 1, a weeding section is provided between the front wheel and the rear wheel, and the weeding section is composed of a tooth and an inter-row rotor, and weeds grown around the seedlings planted in the field. It is for weeding.

Japanese Patent Application Laid-Open No. 2015-12302

FIG. 3 is a diagram schematically showing the flow of mud when the mud guide plate is not provided on the wheel support portion 18. The weeder described in Patent Document 1 has a front wheel structure shown in FIG. 3, and when weeding is performed in a deep wet field, the front mud is pushed by the wheel support portion 18 of the front wheel 12, and the pushed mud is shown in FIG. Seedlings N that swelled in the direction of arrow 100 in 3 and were transplanted to the paddy field were knocked down, and the seedlings Nb were sunk in the mud, resulting in a shortage of stock and a decrease in yield. There is a problem that it is necessary to dig up the work.

The present invention has been made in view of such circumstances, so that the wheel support portion of the paddy field work machine does not push mud and knock down the seedlings, and the work of raising the seedlings of the worker becomes unnecessary, and the yield is increased. The purpose is not to reduce it.

In order to solve the above problems, the first invention of the present application is to support wheels from a main frame in a traveling vehicle body of a passenger-type aircraft having a working device on the traveling vehicle body of a paddy work machine and having a main frame, front wheels and rear wheels. The wheel is supported by the portion, and a wheel support portion provided with a mud guide plate is provided.

The second invention of the present invention is the mud guide plate of the first invention, and the mud guide plate is provided in front of the wheel support portion, and the wheel side is inclined.

According to the first invention of the present application, the mud guide plate attached to the front of the wheel support portion of the paddy field working machine prevents the seedlings from being knocked down by mud, prevents the seedlings from being lost, and can expect a stable yield.

In particular, according to the second invention of the present application, by providing the inclined portion of the mud guide plate on the wheel side, the mud in front of the wheel support portion is surely flowed toward the wheel and the mud is suppressed from being pushed toward the seedling side. can do.

It is a side view of a paddy field work machine. It is a top view of the mud guide plate. It is the figure which showed typically the flow of the mud when the mud guide plate is not provided in the wheel support part. It is a figure which represented typically the flow of the mud when the mud guide plate is provided in the wheel support member.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the present application, the traveling direction of the paddy field working machine is referred to as "forward direction", and the direction opposite to the traveling direction of the paddy field working machine is referred to as "rear direction". "May be attached.

In the present embodiment, as shown in FIG. 1, a paddy field weeder in which a weeding unit is provided in the paddy field working machine will be described. FIG. 1 is a side view of the weeder 1. This weeder 1 is a device for removing weeds growing around seedlings planted in paddy fields.

As shown in FIG. 1, the weeder 1 of the present embodiment includes a traveling vehicle body 10, a weeding device 20, and a drive mechanism 30.

The traveling vehicle body 10 is a passenger-type aircraft including a main frame 11, front wheels 12, rear wheels 13, an operation unit 14, a driver's seat 15, and an elevating link 16. Mainframe 11 is. It is supported by the front wheels 12 and the rear wheels 13.

In the present embodiment, the traveling vehicle body 10 is a tricycle having one front wheel 12 and two rear wheels 13. The front wheels 12 are arranged in the front center of the traveling vehicle body 10. Further, the rear wheels 13 are arranged behind the traveling vehicle body 10 with a space between the left and right sides.

The traveling vehicle body 10 is provided with a traveling drive mechanism, and the engine 17 is used as the traveling drive mechanism. The front wheels 12 and the rear wheels 13 of the present embodiment are respectively connected to the engine 17 via a power transmission mechanism (not shown). The engine 17 is also used to drive the weeding section.

The mud guide plate 50 of this embodiment is provided from the main frame 11 to the lower front portion of the wheel support portion that supports the front wheels 12 by the wheel support portion 18.

The mud guide plate 50 has a right-angled triangle shape, and the adjacent side of the triangle is fixed to the wheel support portion 18 with bolts, and the mud guide plate 50 is installed so that the hypotenuse side comes to the front wheel 12 side.

The inclination of the mud guide plate 50 has an acute angle toward the wheel with respect to the linear plate extending in the direction of travel parallel to the wheel and the linear plate extending parallel to the wheel in a plan view. There is.

Hubcaps 19 are bolted to both ends of the front wheels 12. In the present invention, the wheel cap 19 having the wheel support portion 18 side thinned is fixed. By thinning the wheel cap 19 on the wheel support portion 18, it was possible to secure a wide space for the mud in front of the wheel support portion 18 to be pushed and enter.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and is appropriately modified and embodied as described below without departing from the spirit of the invention. You can also do it.
(1) Change the number of front wheels 12 (for example, two wheels, etc.).
(2) Install a work device (grooving machine, pesticide sprayer, granulator, etc.) other than the weeding device 20.
(3) Attach the mud guide plate 50 to the wheel support by a method other than bolts.
(4) Deform the shape of the mud guide plate 50 (fan shape, rhombus, etc.).

As an example, the operation of the mud guide plate is schematically shown in FIG. When the paddy field working machine moves forward, the mud in the field is pushed out in the direction of the arrow 100 by the mud guide plate 50 installed on the wheel support portion 18. Since the mud is not pushed out in the direction of the seedlings, the seedlings in the rearward direction R are not collapsed.
