Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a cross-sectional view of a portion of the lorry to which the present invention is applied, and FIGS. 2 to 5 show an operation state and a cross-sectional view of a transfer mechanism of the present invention, and FIG. Incision plan section.

Here, the present invention is a freight car having a flat bottom surface, and does not need to have a lift device or a conveyor device such as a dump truck on its own, and the device of the present invention has an upper surface of which the bottom surface slides back and forth. The rack mechanism 10, the rack bar portion 20 which is connected to the left and right side walls and installs and attaches the lower rack bar and the upper rack bar, and the lower conveyance mechanism portion 30 and the upper conveyance mechanism portion 40 which mesh with the rack bars to convey the carry-out wall. ), And a switching mechanism 50 before and after, and a carrying-out wall 60 for mounting the carrying-out wall.

The upper slide mechanism 10 is located on the bottom surface of the lorry, and has a bottom surface reciprocating in the front and rear direction by connecting a driving device such as a reciprocating hydraulic cylinder to a part thereof.

For example, as shown in FIG. 1, a roller 14 is installed at an upper end of a horizontal frame 13 installed on an upper portion of the base frame 11, and the reciprocating hydraulic pressure connected to the base frame 11 is mounted on the roller 14. The bottom member 15 which repeats the slide motion in the front-back direction by the reciprocation of the cylinder 12 is equipped.

The bottom member 15 may be composed of one plate, or a plurality of plates may be combined to slide each other at different time intervals. Here, the forward direction refers to the direction of lowering (unloading) the load, and refers to the rear door direction of the loading box, and the backward direction refers to the opposite direction of carrying out (lowering) the loaded cargo.

In addition, the drive source of the hydraulic cylinder 12 may be utilized from the hydraulic apparatus arrange | positioned at a truck, or may install and use a separate drive source.

Next, the rack bar 20 is connected to the support column 21 by being directly connected to the bottom member 15 for the reciprocating slider as shown in FIG. 1, and further includes a lower rack bar 22 having a gear 23 attached to the side wall. Have it.

For example, the lower rack bar 22 may be formed of a steel plate having a cross-section “c” shaped as shown in FIG. 5, and the transfer roller 24 may be installed on the wall to smoothly move to the center.

The lower rack bar 22 is installed so that the two lower rack bars oppose along the left and right side walls. In addition, the upper rack bar 25 is fixed to the side wall surface separately from the lower rack bar 22 that interlocks with the bottom member 15 to some extent parallel to the lower rack bar 22 and the gear 26 is installed. Install it to face left and right.

In other words, the lower rack bar 22 moves along the reciprocating slide of the bottom member 15, but the upper rack bar 25 is fixed to the wall and does not slide.

The lower transfer mechanism unit 30 and the upper transfer mechanism unit 40 are installed, and the lower transfer mechanism unit 30 forms a frame 31 coupled to the lower rack bar 22 as shown in FIGS. 2 to 4, and the frame At 31, the support piece 32 is installed vertically, and the support plate 32 is attached to the support piece 32 with the shaft 33 interposed therebetween, and at the same time, the engaging plate 35 having the shaft plate 34 fitted thereto is attached. It arrange | positions, The latching piece 36, 37 is crimped | bonded by the shaft 36a, 37a on each of the front and back sides of the locking plate 35, respectively.

In addition, a spring is installed between the engaging pieces 36 and 37, and the stoppers 38 and 39 are provided at the outer positions of the shafts 36a and 37a.

That is, either the front side engaging piece 36 and the rear side engaging piece 37 stop at either side when the lower rack bar 22 moves forward or backward, but when the lower rack bar 22 moves in the opposite direction, the locking piece moves upward. It is a mechanism that moves while sliding and stops only in one direction when the stop is terminated.

This is installed on each of the left and right side wall surfaces as shown in FIG. 6 and is moved by the switching mechanism unit 50 described later.

The upper conveying mechanism part 40 is also substantially the same as the lower conveying mechanism part 30, and has a frame 41 that engages the upper rack bar 25, and vertically supports the support piece 42 from the frame 41. In addition, the shaft 43 is mounted on the support piece 42, the shaft plate 44 is fixed, and the locking plate 45 is sandwiched between the shaft plates 44, and the upper rack bar ( The front locking piece 46 and the rear locking piece 47 are provided as the shaft 47a so as to be engaged with the gear of 25) and are tensioned with a spring between them.

However, the lower transfer mechanism unit 30 moves forward when the lower rack bar moves forward, and stops at the position when the lower rack bar retreats, but the upper rack mechanism 25 is fixed to the upper transfer mechanism unit 40. It does not reciprocate itself, and functions to fix the carry-out wall 60 there when the lower transfer mechanism part reciprocates.

Therefore, in the upper conveyance mechanism part 40, when the upper conveyance mechanism part 40 advances, the front side catching piece 46 slides a gear upper surface, and conversely, when the upper conveying mechanism part 40 retreats, the front side catching piece 46 The position of the stopper 48, 49 is made into the inner position of the shaft 46a, 47a with the lower feed mechanism part 30 so that () becomes in gear with the gear 26. As shown in FIG.

In addition, a switching mechanism 50 is provided between both the lower transfer mechanism 30 and the upper transfer mechanism 40. The switching mechanism 50 is first relatively long in consideration of the distance between the shaft plate 44 of the upper transfer mechanism portion 40 and the shaft plate 34 of the lower transfer mechanism portion 30, and the left and right upper transfer mechanism portion 40 at its tip. The switching rod 51 is installed between the shaft plates 44 of the head).

The engaging plates 35 and 45 of the lower conveyance mechanism part 30 and the upper conveyance mechanism part 40 connect the shafts 36a, 46a, 37a, and 48a to the interlocking bars 52 and 53. By connecting by the front and rear rotation of the switching rod 51, the locking plate 45 of the left and right upper transfer mechanism portion 40 moves in the front and rear direction and at the same time the lower transfer mechanism portion 30 by the interlocking of the interlocking bars (52, 53). The locking plate 35 also moves forward and backward at the same time.

The switching rod 51 is fixed to the motor 54 to the carrying-out wall 60 in the center as shown in Figure 7 and is connected to the arm 56 to the rotation shaft 55 of the motor 54, arm 56 ) And the rotation bar 51 is installed freely.

However, the arm 56 rotates by the rotation of the motor 54, and the switching rod 51 can be switched back and forth by the action thereof.

It is connected to the frames 31 and 41 of the upper conveyance mechanism part 30 and the lower conveyance mechanism part 40 to form a carrying-out wall 60 which is orthogonal to the left and right sidewall surfaces.

The carrying out wall 60 is fixed at the position when the upper surface retreats, and since the loaded cargo blocks the retreat according to the retreat of the upper surface, the loaded cargo 60 is advanced according to the shape or type of the loaded cargo. Determine the size or material of the dose.

Referring to the operation of the present invention made of such a configuration as follows.

First, the carrying-out wall 60 is located in the inner corner of the storage box of a wheel, and it demonstrates sequentially from the case where it moves forward.

When advancing the carrying out wall 60, it starts and rotates the motor 54 of the switching mechanism part 50, the arm 56 is rotated, and the switching rod 51 is rotated in a forward direction. That is, as shown in FIG. 3, the engaging plates 35 and 45 of the upper conveying mechanism part 40 and the lower conveying mechanism part 30 are inclined in the left and right directions in the drawing, and the front locking pieces 36 and 46 are the upper rack bars. And gears 23 and 26 of lower rack bar 22.

Next, when the hydraulic cylinder 12 connected to the base frame 11 is driven to extend the rod, the bottom member 15 connected to the rod slides forward on the roller 14.

When the bottom member 15 slides, the lower rack bar 22 directly connected to the support column 21 moves along the feed roller 24 installed on the side wall. As the lower rack bar 22 moves forward, the front locking piece 36 is brought into contact with the gear 23 of the lower rack bar 22 as described above. As a result, the entire lower transfer mechanism 30 is lowered. Attached to the rack bar 22, the carrying-out wall 60 connected thereto is interlocked. At this time, the load loaded on the bottom member 15 is advanced at the same time as the sliding action of the bottom member 15, which is smoothly transported while being back-pressured by the interlocking wall 60.

On the other hand, the upper transfer mechanism portion 40 is the upper rack bar 25 is fixed to the wall can not be advanced like the lower rack bar (22). That is, the front locking piece 46 of the upper transfer mechanism portion 40 is engaged with the gear 26 of the upper rack bar 25 as shown in FIG. 3, but the stopper 48 of the front locking piece 46 is the shaft 46a. When the upper transfer mechanism 40 is advanced in the inner position of the front side, the front engaging piece 46 acts on the gear 26 upper portion and simply moves to the lower transfer mechanism 30 through the movement bars 52 and 53. Therefore, only the forward is not active to send the export wall (60).

However, when the hydraulic cylinder 12 is switched in reciprocation and the piston rod contracts, the upper transfer mechanism 40 serves to fix the discharge wall 60. In other words, when the bottom member 15 slides backward in the hydraulic cylinder 12 and the lower rack bar 22 moves backward through the support column 21, first, the front side of the lower transfer mechanism part 30 is caught. 36 slips over the upper gear 23 of the rack bar 22, and the gear is not engaged in the reverse direction. Thus it stops at that location.

However, in reality, the load is compressed according to the retreat of the bottom member 15 due to the heavy load, and the lower transfer mechanism part 30 is also inevitable.

However, the upper transfer mechanism portion 40, in which the stopper 48 of the front locking piece 46 is inside the shaft 46a, moves downward by the lower transfer mechanism portion 30 to move upward through the movement bars 52 and 53. When a force for retreating movement is applied to the mechanism part 40, the rear locking piece 47 is securely engaged with the gear 26 of the upper rack bar 25 to the upper rack bar 25 of the upper transfer mechanism part 40. While in the state, the lower transfer mechanism part 30 and the carrying out part 60 connected thereto are firmly fixed at the position.

When the bottom member 15 retreats, the carry-out wall 60 fixed to the upper transfer mechanism 40 with respect to the cargo to be retracted interlocks in that position and the upper surface retreats. It stops in the state and secures the position as it advanced.

Next, when the hydraulic cylinder 12 transfers the bottom member 15 in the forward direction while the reciprocating motion is started again, the above action is repeated. As a result, the load is forwarded one by one whenever the reciprocating force of the hydraulic cylinder 12 is repeated. It is then discharged completely as it reaches the end close to the door of the loading box.

The discharge is in the form of moving forward and at the same time moving the cargo loaded on the bottom member 15 is fixed to the carrying out wall 60, and is a form that goes forward daily, even if the required amount of take out is very efficient.

When the carry-out wall 60 reaches the door and the closest position, the engagement of the engaging plates 35, 45 and the engaging pieces 36, 37, 46, 47 is switched in the front-back direction.

That is, the motor 54 of the switching mechanism part 50 is started, and the switching rod 51 is rotated backward by the rotation of the arm 56. As shown in FIG. Then, the shaft plate 44 is rotated by the rotation of the switching bar 51, the locking plate 45 is rotated around the shaft 43, the engagement of the locking piece 46 is terminated, and the locking piece 47 is reversely Engage with the gear 26 of the upper rack bar 25. (See FIG. 4) At the same time, the locking plate 35 of the lower transfer mechanism part 30 also rotates through the movement bars 52 and 53, and the engagement of the locking piece 36 is released to reverse the locking piece 37. It becomes a relationship to mesh with the gear 23 of the lower rack bar 220.

When the hydraulic cylinder 12 is reciprocated in the same shape, the same action as described above this time moves with the gear 23 of the locking piece 37 of the lower transfer mechanism part 30, the locking piece 46 of the bar 22, and moves daily. The retraction movement returns the carry-out wall 60 to the initial position. At this time, the carry-out wall 60 can also be stopped at an arbitrary position in accordance with the load position of the load.

As a result of this function, only the reciprocating motion of the hydraulic cylinder is an easy mechanism for both forward and backward movements of the discharge wall.

In addition, the red cargoes that are the subject of the present invention are a) fertilizer, feed, grass, bark b) demolition or tob, timber, beet pulp pulp) c) glass powder, airspace d) waste paper, boxes, tires, pulp, etc. e) solid waste and dismantled wood, etc.

8 is a view showing another embodiment of the present invention.

Install a hydraulic cylinder connected to a part of the base frame to install a roller on the yellow port on the main port, and install a bottom member on the upper part of the roller, and connect the bottom member and the hydraulic cylinder to the bottom by reciprocating the hydraulic cylinder. The reciprocating sliding of the member in the front-rear direction is the same as described above.

Therefore, the description of FIG. 8 is a structure in which the sprockets 72 and 73 are provided on the left and right side wall surfaces, and the carry-out wall 60 is provided between the chains 71 by winding the chains 71 thereon.

The sprockets 72 and 73 are electrically connected to the hydraulic cylinders to rotate the motor connected to the sprockets 72 and 73 which are matched when the hydraulic cylinders reciprocate, and at the same time as the bottom member 15 advances. The carrying out wall 60 is advanced.

However, when the hydraulic cylinder is restored, the rotation of the motor of the sprockets 72 and 73 is stopped to operate the lock mechanism on the discharge wall 60.

As a result, as in the above-described embodiment, it is possible to move forward one by one along the reciprocating slide of the hydraulic cylinder and to carry out the cargo.

As described above, the present invention can be carried out in the form of advancing the cargo forward in a daily manner by combining the bottom slide and the transport wall at the same time, so that the amount of the cargo is reduced and the structure and mechanism are reasonable. In addition, the operation cost is also low, and there is no need for a lifting device such as a dump truck, so there is no danger of falling during work, and safe work is possible. It also has a simple structure because no conveyor is required.

The device itself is light in weight, and the length of the bottom plate can be freely designed so that the load can be greatly increased.
