Description

[Detailed explanation of the idea] The present invention relates to an agricultural and horticultural vehicle.

Conventionally, in this type of vehicle, as shown in Figure 1.2, a loading device A for loading packed grass onto a truck or the like is detachably attached to the side of a cradle C of the vehicle body B. There are some with a hole for pulling in with a tractor.

However, in this vehicle, when the pedestal C was full of grass, the device A was removed, transported to the grass collection area, unloaded, and then returned again to attach the device A and carry out the loading work. The work efficiency was poor, and there was a risk that the device A would come into contact with the vehicle body B and be damaged when working on a slope in a narrow space.

An object of the present invention is to provide an agricultural and horticultural vehicle that allows the driver to work safely and improve work efficiency.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. The agricultural and horticultural vehicle according to the present invention includes a vehicle main body 1
It is equipped with a loading device 3 for loading agricultural and horticultural products on the ground onto a cradle 2 arranged at the rear of the vehicle body 1.
from the front side of the device 3 to the front part of the pedestal 2,
can be freely folded approximately at its center by a central horizontal axis 4,
A switching means 5 is provided for switching the device 3 between an extended use state and a folded storage state E suitable for vehicle travel.

The vehicle main body 1 has a pedestal 21 at the rear, a driver's cab 6 at the front right side, and a loading section 7 for the loading device 3 at the front left side. A doglegged link 8 is rotatably supported via a first horizontal shaft 9, and the tip of the link is rotatably connected to the front portion 3a of the loading device 3 via a second horizontal shaft 11. Ru.

Further, the base ends of two supporting members 12.13 are connected to the upper part of the mounting portion 7 by respective shafts 14.15, and both supporting members 12.1
3 are overlapped with each other and are connected and fixed to each other by a reinforcing material 16.

The rear portion 3b of the loading device 3 is rotatably supported at the overlapping end portion of the support member 12, 13 via a third horizontal shaft 18.

A four-speed link mechanism 17 is constituted by the virtual link 10 between the first horizontal shaft 9 and the third horizontal shaft 18 of the loading section 7, the doglegged link 8, and the front section 3a and rear section 3b of the loading device. be done.

Further, the switching means 5 is constituted by a pneumatic or hydraulic cylinder 19 whose base end is pivoted to the lower end of the mounting portion 7 and whose tip end is connected to the bracket 8a of the link 8.

The cylinder can be switched between a free state in which it is allowed to expand and contract, and a held state in which it maintains its extended and contracted position.

Further, the loading device 3 is provided with a claw-equipped transfer conveyor 3C on the surfaces of its front portion 3a and rear portion 3b, and a running wheel 20 is provided at the lower end of the front portion 3a.

In the above configuration, during loading work, as shown in FIG. 4, the cylinder 19 is shortened, the running wheels 20 are placed on the ground, and the loading device 3 is placed in the extended use state.

In this case, the packed agricultural and horticultural products are pulled up to the upper part of the pedestal 2 by the conveyor 3c of the device 3.

In addition, since the virtual link 10, the doglegged link 8, the front part 3a and the rear part 3b of the device 3 constitute a four-speed link mechanism 17, if the cylinder 19 is switched to the free state, it is possible to move on uneven ground while driving. It is possible to overcome it.

Next, at the time of forwarding, if the cylinder 19 is extended as shown in FIG.
a is lifted upwards.

At the same time, the device 3 rotates around the horizontal axis 18, but since the front part 3a and the rear part 3b are pivotally connected around the horizontal axis 4,
The front part 3a moves substantially vertically and the rear part 3b moves substantially horizontally, and the device 3 is folded into a dogleg shape and switched to the folded storage state E.

At this time, by holding the cylinder 19,
It is possible to stop the swinging of the device 3 in the vertical and horizontal directions,
General driving is possible.

As is clear from the above explanation, the present invention provides an agricultural and horticultural vehicle equipped with a loading device for loading agricultural and horticultural products on the ground onto a pedestal placed at the rear of the vehicle body. The loading device is arranged from the front side of the loading section of the vehicle body to the front part of the cradle, and the loading device is divided into two parts at approximately the center thereof, into a front part and a rear part, and the front part and the rear part. is foldable around a central horizontal axis, a rear end of the rear part of the apparatus is pivotally connected to a virtual link formed from the mounting part, and a second link is provided between the front end of the front part of the apparatus and the virtual link. (in the embodiment, the dogleg link 8) is interposed to form a four-speed link mechanism. A switching means consisting of a cylinder interposed between the second link and the mounting section is provided in order to switch the lower end of the link to a folded storage state suitable for vehicle travel when the lower end approaches the mounting section. This invention relates to an agricultural and horticultural vehicle characterized by the following.

Therefore, according to the present invention, agricultural and horticultural products can be loaded from the front of the vehicle, so the driver only needs to pay attention to the front, improving work safety. Because it is firmly attached to the vehicle body without protruding from the surface, it can be used for work on slopes or in narrow spaces.

Furthermore, according to the present invention, the loading device can be folded, the overhang on the front side can be reduced, and driving during forwarding is very easy. There is no need to remove the device from the vehicle body as in the past, and work efficiency can be improved.
