Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The agricultural work of the present invention relates to a riding-type working machine towing vehicle for towing machinery.

[Prior art] Conventional riding type work machine towing vehicle/V-tow vehicle In particular, a riding type work machine towing vehicle that tows various types of agricultural work machines such as rice field machines by connecting them to the rear of the vehicle body is easy to operate. The main focus is often placed on the vehicle body structure and parts arrangement, and although the driving operation is generally satisfactory, on the other hand, it is difficult to perform operations related to the working machinery towed by the vehicle, such as towing a rice transplanter. There were many inconveniences and inconveniences in the operations of replenishing seedlings and in getting on and off between the width and the ground at that time. In other words, when replenishing the rice transplanter with the next seedling, even if this supplementary seedling is loaded on the side of the vehicle in an adapter cage, it is not possible to pick up and load the supplementary seedling from the vehicle. It was difficult, and I had to get out of the mold each time to perform replenishment operations, which was a hassle.

In addition, it is customary to have a minimum of 4 steps for going up and down at that time, so it is necessary to be very careful when going up and down narrow roads, etc., and you may be forced to take an unreasonable posture. Tozuru.

[Purpose of the Invention] This invention was devised in view of the above-mentioned problems, and it is possible to prevent the towing vehicle from moving on the left and right sides of the driver's seat and behind the driver's seat without deteriorating the drivability of the towing vehicle. The purpose is to improve the ease of opening operation.

[Structure of the Invention] In order to achieve the above-mentioned object, the present invention provides a method for towing a rice transplanter or other working machine connected to the rear of the vehicle body in a riding-type towing operation, in which the upper floor surface of the vehicle body frame for this towing operation is towed. The engine is surrounded by an engine cover with a driver's seat located above, and a steering mechanism support frame including instruments and other equipment is surrounded by the cover, and the driver's seat can be rotated horizontally. A configuration of a riding-type agricultural working machine, which is characterized by having a mechanism capable of carrying the vehicle and having a floor surface around the driver's seat on which one can place his or her feet while sitting on the driver's seat. And so.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The engine 3 for towing a rice transplanter as the working machine 1 of this embodiment is not installed on the body frame 5 in front of the driver's seat as in the conventional case, but is shifted to the rear and placed behind the driver's seat 7. It's below. An engine cover 9 with a driver's seat 7 provided above is provided to surround the engine 3. The driver's seat 7 has an engine cover 9 at the center of its lower surface.
It is supported on the upper surface by a shaft support 11NM411 so as to be horizontally rotatable in the entire circumferential direction. The driver's seat 7 can be oriented and fixed in any direction using a stopper mechanism 13 that is a combination of a lever operation locking pawl and a toothed shaft that can be operated while sitting on the driver's seat 7. 49 is a front wheel, and 51 is a rear wheel.

The level near the top of the vehicle body frame 5 of this vehicle is defined as a floor surface 15, and a steering mechanism support frame 17 is protrudingly disposed in front of the driver's seat 7 and surrounded by a cover 19. The lower portion of the steering mechanism support frame 17 is slightly enlarged, and is provided with a speed change operation lever 21, a working machine operation lever 23, etc., which are arranged adjacent to the steering mechanism. A steering handle 25, a throttle lever 27, instruments, various lamps, etc. are provided on the upper part of the steering mechanism support frame 17.

A brake pedal 29, a clutch pedal 31, etc. are provided on the left and right floor surfaces of the steering mechanism support frame 17.

In the above, the parts arranged on the floor surface 15 above the vehicle body frame 5 are only the engine 3, the engine cover 9, the steering mechanism, the support frame 17, the cover 19, various levers, various pedals, etc. Around the driver's seat 7, which can be rotated and stopped, a floor surface 15 of a width and height is provided all around the driver's seat so that the driver can comfortably place his or her feet while sitting on the driver's seat. In front of the driver's seat 7, there is a link mechanism 33 for connecting and operating the working machine 1 behind the driver's seat 7.
Although the floor surface 35 is at a slightly higher level than the side portions, the height is such that the driver can comfortably place his or her feet on the rear floor surface 35 while sitting with the driver's seat 7 facing rearward.

The rice transplanting device, which is the working machine 1, includes a seedling tank 43 for loading and supplying seedlings, and a planting H@45 for separating and planting the seedlings supplied from the seedling tank 43. It consists of a float 47 supporting the lower part, etc., receives power from the engine 3 to plant seedlings, and can be raised and lowered with respect to the vehicle body frame 51 by a hydraulic mechanism via a link mechanism 33.

With the above-described arrangement, the floor surfaces 15, 35 in front, sides, and rear of the driver's seat 7 on the vehicle body frame 5 are wide and can be used as work passages. A frame 37 with rails is attached to the front and rear of the vehicle, that is, to the side of the vehicle body frame 5 as shown in the figure, and a shelf frame 39 for storing spare seedlings is mounted on this frame via wheels 41 so that the frame 37 can be moved in the front and rear direction of the vehicle body. In order to automatically stop the shelf frame body 39 moving forward and backward of the rail, a car locking mechanism (not shown) consisting of a locking pawl with a spring and a bottle hanging on the pawl is provided. ing.

With this configuration, a wide and low floor surface 15 is secured on the upper surface of the vehicle body frame 5, which serves as a work space and a work passage. Also, by eliminating the engine compartment, bonnet l-, etc. that used to be in front of the driver's seat 7, the forward visibility has been greatly expanded, making it possible to check the ground, rice fields, etc. in front of the car, especially in the direction of the car's path. It became so.

In addition, a floor surface 15 connected to the floor surface 15 in front of the driver's seat 7 is secured on both the left and right sides of the driver's seat 7, and from these floor surfaces 15 to the floor surface 35 behind the driver's seat 7, although there is a slight difference in level. Because the driver's seat 7 can be rotated 360 degrees and stopped, there is no need for the driver to forcefully twist or bend his body. Seedling loading work can be carried out extremely easily. By turning the driver's seat 7 in that direction and stopping it, depending on the situation, the operator can work even while seated. Or driver seat 7 in the back
It is also easy to observe in detail the picking up of seedlings, planting status, etc. Driving operations with the driver's seat 7 facing forward can be done in the same way as before, or the visibility has been significantly improved, making operations safer and easier.

The present invention is not limited to the embodiments described above, but can be similarly applied to riding-type work equipment towing vehicles that tow various types of work machines, and exhibits the functions described above.

[Effects of the Invention] As detailed above, the riding type work equipment towing vehicle using the configuration of the present invention has greatly improved operability by improving the forward visibility, and is particularly effective when moving on small objects. Movement and work on both sides of the driver's seat and behind the driver's seat can be done extremely easily and reliably, and it is also extremely easy to get on and off the vehicle between the vehicle and the ground. Therefore, safety, including driving, work, and other operations, is greatly improved.
