Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seat support device for a passenger management machine, and more particularly to a seat support device that can be easily attached and detached.

[Prior Art] Conventionally, a seat support device for a passenger management machine of this kind has a support provided on a frame, and a seat is fixed to the upper end of the support. When performing disinfection work, fertilization work, etc. using the riding control machine, a tank is placed on the rear or side of the seat, and the tank is filled with disinfectant solution or fertilizer solution and the respective work is performed. Is going.

[Problems to be Solved by the Invention] In the conventional passenger management machine, the seat support is fixed to the frame, and the seat is not configured to be easily removed. Therefore, the sheet may get in the way when a tank of disinfectant or the like is placed, or the loading space may be limited.

Therefore, a technical problem arises that must be solved in order to facilitate the attachment and detachment of the seat and to effectively utilize the loading space, and the present invention aims to solve this problem.

[Means for Solving the Problem] The present invention has been proposed to achieve the above object, and includes providing a step floor plate on the upper part of the frame, drilling an insertion hole in the step floor plate, and A passenger control device characterized in that the upper end of a mounting pipe fixed to the frame is peeked out from the insertion hole without protruding upward, and the lower end of the seat support is fitted into the mounting pipe so as to be freely inserted and removed. The present invention aims to provide a seat support device for the following.

[Function] This invention allows the upper end of the mounting pipe to be seen through the insertion hole drilled in the step floor board. The mounting vibe is erected on the frame, and its two ends are formed so as not to protrude upward from the insertion hole. Furthermore,
The lower end of the seat support is inserted into the mounting vibe to support the seat. When the seat is not in use, the loading space can be expanded by pulling out and removing the seat support from the mounting vibrator. Moreover, since the upper end of the mounting vibrator does not protrude above the upper surface of the step floor board, no protrusion will be formed on the step floor board after the seat is removed.

When installing the seat, the seat support is inserted into the mounting vibe and fixed with a lock bin or the like, if necessary. In this way, the range of use of the passenger management machine can be expanded by easily attaching and detaching the seat.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, conventionally known technical matters will also be explained at the same time. Figures 1 to 3 show a passenger management machine, and reference numeral (1) represents a frame of the passenger management machine, and an engine (2) is mounted on the front part of the frame (1). The rear part of the frame (1) is separated into a left frame (3) and a right frame (4) and extends rearward. The left and right frames (3) and (4) each have a lower link (5) (
The tip of 5) is pivotally attached, and the lower link (5X5)
A hydraulic cylinder (6) (6>) is fixedly installed on the upper surface of the rear end.

The spool (7) of the hydraulic cylinder (6) is connected to the top of an actuating piece (8) erected on the upper surface of the front end of the lower link (5), and is connected to the top of an operating piece (8) that allows the hydraulic cylinder (6) to expand and contract. The spool (7) pushes and pulls the top of the actuating piece (8) back and forth. In this way, the lower links (5) (5) rotate around the pivot joint (5), and the lower links (5X5)
The rear end moves up and down.

Also, the seat (9) pillar (1) is attached to the rear of the right frame (4).
, o), and a hydraulic control valve Q +
) will be fixed. An operating lever (O) provided on the side of the seat (9) is pivotally attached to the middle part of the support column (10), and by rotating the operating lever (O) either forward or backward, the control valve (L1) can be operated. The lower links (5) (5) are operated to raise and lower the lower links (5).Furthermore, a step floor plate (a seagull) is provided on the upper surface of the left and right frames (3) (4), and a hydraulic cylinder (6) is provided. (6) and control valve 01
) is covered.

Therefore, it is possible to maintain a sufficiently high minimum ground clearance while keeping the center of gravity low.

Here, regarding the support device of the sea 1-(9), the fourth
This will be explained according to the drawings and FIG. A plate is fixed to the lower end (100) of the pillar (10), and a cylindrical mounting portion θ is vertically provided on the lower surface of the plate. Lower the piece 00 and attach the locking piece (111
A hole (r7) is bored in the lower end of the hole (r7). On the other hand, an insertion hole is drilled in the step floor plate 01, and a vibrator is fixedly attached to the frame 0 below the ridge.

This mounting vibe ■ has an inner diameter slightly larger than the diameter of the mounting portion θ, and its upper end (1, 9a) is connected to the insertion hole (
It is formed so that the step floor plate (one hole (4) does not protrude from the top surface of the step floor plate) so that it can be seen inside. .

Therefore, before inserting the mounting part (l→) vertically installed on the lower end (10a) of the support column (10) into the mounting pipe, the locking piece (
1 [+] into the hole [phase], and then move the support column 00 downward and fit the mounting part (hook) to the mounting vibe (hook) as shown in FIG. Insert a pin to prevent removal (<21) into the hole (r7) of the frame (10).In this way, the mounting vibe (casting support Qo) of the frame (1) is fixed, and as shown in Figure 1. The seat (9) is now attached.Also, if you pull out the support (10) from the attached vibrator by performing the opposite operation to the above, the seat (9) can be attached very easily and quickly. can be removed.

In addition, the operating lever 0 which is pivotally attached to the middle part of the column Qo)
A link @ is connected to the seat (9), and when the support column Qo) is pulled out, this link (to) is also removed, and the seat (9) and the operating lever 0 are removed integrally. Therefore, the sheet (
After removing the step floor board (9), no protrusions appear on the top surface of the step floor board (1).

Since the seat (9) is capable of attaching and detaching the support column (10) and operating lever 0 in one piece, the loading space can be expanded, and the step floor plate 0 retracting protrusion is removed when removed. Since this does not occur, safety for workers is also good. Therefore, when disinfecting or fertilizing crops, for example, a large pest control tank can be placed after removing the sheet, and work efficiency can be improved. Furthermore, even when the seat (9) is installed, the step floor plate 01 at the bottom of the seat (9) is offset because the support column 00) is offset to the frame (4) on one side as shown in Fig. 3. A space (to) is formed. This space can be effectively used as a storage space for luggage, etc., and since there is no structure other than the pillar (lO), luggage can be taken in and out easily.

Note that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to such modifications.

[Effects of the Invention] According to the present invention, the seat support can be freely inserted and removed, so that the seat can be removed from the vehicle body when the seat is not in use. This attachment/detachment work is extremely simple, and all you have to do is pull out the seat support from the attached vibrator.

Moreover, there are no protrusions on the step floor board after it is removed, which improves safety for workers and makes it possible to use storage space effectively. It is an invention that plays.
