[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a shutter device that prevents the root vegetables in the tank of a root vegetable harvester from spilling when the tank is dumped up.

[0002]

[Prior art and problems]

 A shutter device for a tank of a root vegetable harvester having a structure as shown in FIG. 13 is known. This shutter device is provided with a concave-shaped inlet / outlet portion 2'in which a conveyor moves in and out on one side of a tank body 1 ', and an arc-shaped sled 5 is provided inside columns 3'standing and fixed on both sides of the inlet / outlet portion. 'Is attached vertically, and aside from this, a flexible shutter plate 8' (rubber plate 8 ') having a width corresponding to the height of the sled 5'and a width corresponding to the lateral width of the entrance / exit portion 2'is formed. The lower end of the shutter plate is fixed to the lower end edge of the entrance / exit portion 2'over the entire length, and the mounting rod 7'is attached horizontally to the upper end of the flexible shutter plate 8 '(rubber plate 8'). Insert both ends of the'into the sled 5'through the rollers 4 ', and project both ends of the mounting rod 7'outside the sled 5', and put both ends of the mounting rod above the upper part with a coil spring 6 '. It is a structure stretched over. (See Japanese Utility Model Publication No. 3-45535)

To use this shutter device, the tank main body 1 ′ is dumped down, the lower surface of the conveyor (not shown) is lowered, the lower surface of the conveyor rides on the mounting rod 7 ′, and further down, the mounting rod 7 ′ is removed. Since the roller 4'rolls down along the inside of the sled 5'and the sled 5'bends in an arc toward the inside of the tank body 1 ', the flexible shutter plate 8' (rubber The plate 8 ') is folded in half from the middle, and the roller 4'is guided along with the mounting rod 7'to the lower part of the sled 5', and abuts on the column 3'and stops.

When the conventional technique is used as described above, the descending direction of the conveyor and the descending direction of the mounting rod 7'which is pushed down by the conveyor while bulging inward of the tank body 5'along the sled 5 ', Since it is in a different direction, the descending movement of the mounting rod 7'which is pushed down by the descending conveyor is awkward, and there is a concern that it will not descend smoothly. Therefore, the folding operation of the flexible shutter plate 8 '(rubber plate 8') is also awkward, and there is a concern that it will not be smoothly folded. Since the shutter plate is composed of the flexible shutter plate 8 '(specifically, the rubber plate 8'), if it is repeatedly folded in two, it will have a crease and there is a risk of tearing from the crease. There is a problem in terms of strength.

The present invention has been made by paying attention to the above-mentioned problems of the prior art. A root vegetable harvester in which a shutter plate pushed by a conveyor can move smoothly and the strength of the shutter plate is improved. The purpose is to propose a shutter device for tanks.

[Means for solving problems]

 Means for achieving the above-mentioned object is to provide a means in which a conveyor is provided at one side of a tank main body so that the conveyor is rotatable in and out vertically, and the conveyor is provided with a concave-shaped inlet and outlet. Pulleys are provided on the outer surfaces of the columns that are erected and fixed on both sides of the entrance / exit, and the other end of the tension spring is attached to one end of the rope hung on the pulley, and one end of the tension spring is stopped on the outer surface of the tank body. Attached to the other end of the rope that is attached to the pulley and attached to the inside and outside of the conveyor is a connecting rod that is attached to and disengages from the inner surface of the strut. The upper part of the shutter plate is fixed, and the lower part of the inflexible shutter plate is rotatably attached to the inner surface of the tank body below the in / out part of the conveyor. Panned metal or perforated plate, etc. It is that it was constructed.

[0007]

[Work]

 Push the mounting rod with the conveyor while rotating it downward into the concave-convex conveyor entrance / exit on one side of the tank body, and the lower part of the inflexible shutter plate will center on the part where it is attached to the inside of the tank body. Then, the inflexible shutter plate is rotated toward the lower inside of the tank body against the elastic force of the tension spring to open the inlet / outlet portion of the conveyor, and the carry-out end portion of the conveyor is projected into the tank body. To do. Then, when the conveyor is rotated upward to move it out of the inlet / outlet part of the conveyor and return to the original position, the lower part of the inflexible shutter plate pulls the inflexible shutter plate centering on the attachment part with the inner surface of the tank body. The elastic force of the spring causes the conveyor to rotate upward, and at the same time, the conveyor rotates upward toward the inlet / outlet portion of the conveyor, thereby closing the opened inlet / outlet portion of the conveyor.

As described above, the rotation direction of the conveyor and the rotation direction of the shutter plate are substantially the same as the vertical rotation direction.

【Example】

 The tank body 1 is provided with a concave-shaped inlet / outlet portion 2 on one side of the tank wall 10, and the conveyor C can be moved in and out of the inlet / outlet portion. The conveyor C is a well-known conveyor for transporting the harvested product transported by the rotary bucket conveyor 11 into the tank main body 1. Outside the one side of the tank main body 1, the conveyor C is vertically moved toward the tank main body 1 side. It is rotatably installed and can be put in and taken out of the entrance / exit section 2.

The support column 3 is erected and fixed to the tank wall 10 on both sides of the entrance / exit portion 2 of the conveyor C, the pulley 4 is rotatably provided on the outer surface of the support column, and the cord 5 is hung on the pulley. To do.

There are two ways to arrange the pulley 4; one is on the outer surface of the column 3 on one side (see FIGS. 3 and 6) and the other is on the outer surface of the columns 3 on both sides (see FIG. 9). Conceivable. The rope 5 to be hung on the pulley 4 is composed of a rope (not shown), a chain (not shown), etc., the other end of the tension spring 6 is attached to one end of the rope, and the other end of the rope is A mounting rod 7 arranged on the upper side of the inlet / outlet 2 of the conveyor C and engaged with the inner surface of the column 3 is connected.

If the rope 5 is a rope, the connecting means between the rope 5 and the attachment rod 7 is one end portion of the attachment rod 7 (the left end of the portion out of the concave-shaped inlet / outlet portion 2 in FIGS. 3 and 6). Part) or both ends (the left and right ends of the part where the concave-shaped inlet / outlet 2 is removed in FIG. 9), the rope is made to penetrate through a diametrical connecting hole (not shown) and project from the connecting hole. A locking part (for example, a knot that is larger than the connecting hole, a bundling of a locking rod that is longer than the diameter of the connecting hole, etc.) is formed at the end so that it can be locked in the connecting hole. If the rope 5 is a chain, the connecting means may be a connecting means for attaching the end of the chain to the mounting rod 7 with a U-shaped bolt.

The tension spring 6 has one end (the lower end in FIGS. 3, 6 and 9) fixed to the outer surface of the tank body 1 and the other end (the upper end in the same figure) of the cord 5. It is attached to one end portion (the lower end portion in the figure) so as to be constantly urged toward the outer lower side of the tank body 1.

The mounting rod 7 is configured to have a length that can be engaged with and disengaged from the inner surface of the column 3 across the exit / entrance portion 2 of the conveyor C, and the upper side of the inflexible shutter plate 8 for the entrance / exit portion 2 is fixed to the shutter. The shutter plate is pivoted upward about the pivot rod 9 on the lower side of the shutter plate itself, and when the entrance / exit portion 2 is closed, it is arranged above the entrance / exit portion.

The inflexible shutter plate 8 is a sturdy and hard plate member that is unlikely to be broken, bent, or torn, for example, a metal plate (Claim 1, FIG. 1 to FIG. 10), expanded. It is made up of metal (see FIG. 11), perforated plate (see FIG. 12), FRP plate (not shown), etc., and the upper part is fixed to the mounting rod 7, and the lower part is attached to the rotating rod 9. A rotating rod is rotatably attached to the inner surface of the tank body 1 below the inlet / outlet 2 of the conveyor C, and the rotating rod 9 is rotated so that the inlet / outlet 2 can be opened and closed. To do. As a fixing means for the inflexible shutter plate 8 and the mounting rod 7, if both materials can be welded, welding means is used. If both materials cannot be welded, bolts / nuts fixing, bonding, etc. are adopted.

The rotating rod 9 is configured to have a length that traverses the entrance / exit portion 2 of the conveyor C and reaches the inner surface of the support column 3, and both ends thereof are provided on the inner surface of the mouth frame of the tank body 1 (see FIGS. 2 and 8) or The support piece 3 is rotatably attached to the lower side (see FIG. 5) of the column 3.

By the way, in place of the rotating rod 9, a fixing rod (not shown) having the same length as the mounting rod 7 is attached to the lower side of the inner surface of the mouth frame of the tank body 1 or the inner surface of the column 3. 12 and the lower part of the inflexible shutter plate 8 is rotatably wound around the fixed rod, and thus the inflexible shutter plate 8 is rotatably disposed on the tank body 1. The pulley 4, the cord 5, the tension spring 6, the mounting rod 7 and the like described above can be organically combined to form the opening / closing portion 2 so as to be opened and closed.

Next, the usage will be described. While the conveyor C is rotated downward to enter the concave-shaped inlet / outlet 2 provided on one side of the tank wall 10 of the tank main body 1 that has been dumped down, the mounting rod 7 is attached by the rotating conveyor C. When is pressed, the lower side of the inflexible shutter plate 8 is moved to the lower inside of the tank main body 1 against the elastic force of the tension spring 6, with the inflexible shutter plate 8 being centered on the attachment part with the inner surface of the tank body 1. If it is possible to transfer the harvested product conveyed by the rotary bucket conveyor 11 into the tank body 1, the conveyor C is opened to open the in / out section 2 of the conveyor C, and the carry-out end of the conveyor is projected into the tank body 1. Close. Then, as soon as the transfer of the harvested product into the tank body 1 is completed, the conveyor C is rotated upward toward the original position and withdrawn from the entrance / exit portion 2, and the lower side of the inflexible shutter plate 8 is the inner surface of the tank body. The flexible shutter plate 8 is rotated upward by the elastic force of the tension spring 6 toward the entrance / exit portion 2 around the attachment portion of the and, and the attachment rod 7 is released by engaging with the inner surface of the column 3. The inflexible shutter plate 8 closes the inlet / outlet portion 2 that was used to allow the tank body 1 to be dumped up.

[0019]

[Effect]

 Since the present invention is configured as described above, the rotation direction of the conveyor and the rotation direction of the inflexible shutter plate are substantially the same, and the movement of the inflexible shutter plate when the mounting rod is pushed by the conveyor is performed. , And the movement of the inflexible shutter plate due to the elastic force of the tension spring are both effective. Then, when the inflexible shutter plate rotated downward (inclined inflexible shutter plate) is rotated upward by the elastic force of the tension spring to close the entrance / exit, the inflexible shutter plate is erected, so Contaminants (leaves, mud, and gravel that were mixed in or attached to the harvested product) fell from the conveyor to the upper surface of the inflexible shutter plate that was rotated downward (inclined inflexible shutter plate) during transportation of the harvested product. Etc.) is automatically flipped and peeled off when the inflexible shutter plate is erected.

Further, since the shutter plate is an inflexible shutter plate such as a metal plate, an expanded metal, or a perforated plate, the shutter plate is not bent, bent, or has a crease. The worry of tearing is eliminated, and the shutter plate has excellent strength and durability.

Further, if the inflexible shutter plate is composed of an expanded metal or a perforated plate, the harvested product is transferred to the tank main body, and the downwardly rotated inflexible shutter from the conveyor (the inflexible inflexible shutter plate) is placed on the inflexible shutter. There is no small amount of foreign matter that has fallen into the tank body from meshes, through holes, etc. and adheres to the inflexible shutter plate, reducing the risk of overloading the ropes, tension springs, etc. It enables long-term use of strips and tension springs.
