Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a grain tank. More specifically, it relates to a grain tank used for transporting grains harvested in a rice field by a large-scale agricultural machine such as a combine to a drying room etc. on a bed such as a truck, particularly from a grain tank to a drying room etc. The present invention relates to improvement of transfer capacity of a grain tank equipped with a transfer means for transferring grains.

(Background of the Technology) As this type of grain tank, a tank main body formed of a metal plate or a synthetic resin plate in a box shape, and an outflow which is disposed in the tank main body and causes the grain main body to flow in one direction There is a type including a mechanism and a transfer mechanism that is connected to a delivery end of the delivery mechanism and that transfers grain from the inside of the tank body to the outside.

This type of grain tank equipped with a delivery mechanism and a transfer mechanism allows the grains in the tank body to be smoothly and quickly dried in a drying chamber, etc., compared to the case where separate slouches are connected one by one to suck grain from the tank body. It has the advantage of being transportable and is becoming widely used.

(Prior art and its problems) Conventionally, as a delivery mechanism of the above-mentioned type grain tank, a groove provided with a delivery member such as a coil spring or a screw conveyor is known, and as a transfer mechanism, It is known that a flexible tube is provided with a transfer member composed of a coil conveyor inside.

In this conventional grain tank, since the transfer mechanism is provided with a transfer member having a large flow resistance inside a flexible tube having a narrow transfer cross section, clogging may occur depending on the moisture content of the grain. In some cases, a problem such as a decrease in the transfer amount may occur, and there is a problem that the transfer capability is insufficient.

(Problems to be solved by the present invention) The present invention has been made in view of such conventional circumstances, and it is possible to smoothly and effortlessly and easily improve the transfer ability to a drying chamber and the like, and pull out to the drying chamber. It is an object of the present invention to provide an improved grain tank for obtaining.

(Means for Solving the Problem) The technical means taken by the present invention to achieve the above-mentioned object is a grain tank in which a delivery mechanism for unidirectionally flowing grain is arranged at the bottom of the tank body. A drop opening formed downward at the delivery end of the delivery mechanism, a belt conveyor slidably stored under the delivery mechanism, and a belt conveyor projecting forward from below the drop opening to outside the tank body. It is composed of a sliding mechanism and an adjusting mechanism that adjusts the protrusion angle of the belt conveyor to the outside of the tank body to the left, right, up and down, and the adjusting mechanism moves the belt conveyor to the outside of the tank body through the guide wheel of the sliding mechanism. A base that supports the drawer so that it can be moved is arranged below the drop port, and the other end of an arm that has a shaft that supports the base so that it can rotate horizontally is pinned to the bottom frame of the tank body. To Via a pin, the lower side of the shaft is pivotally attached to one end of the arm, and the end of the arm is rotatably and rotatably attached to the end of the arm. It is characterized in that a coil spring for urging coaxially backward from the upper side to the pin at the other end of the arm is installed.

(Operation) Thus, according to the above-mentioned technical means of the present invention, the belt conveyor, which is supported and accommodated by the sliding mechanism and the adjusting mechanism, is provided below the delivery mechanism at the bottom of the tank body. When pulling out to project to the outside front,
The belt conveyor is supported by the spring force of a coil spring that extends from a shaft that is attached to one end of the arm of the adjusting mechanism so as to be rotatable back and forth and a pin that vertically pivots the other end of the arm. As a result, when the belt conveyor is pulled out toward the drying room, etc., the weight of the conveyor itself is not directly applied to the operator, so the burden on the operator is greatly reduced, and it is smooth and unreasonable toward the drying room. Can be pulled out without.

In addition, this type of grain-like tank is placed on the loading platform with the transfer mechanism facing the rear of the loading platform such as a truck, and conveys the grain harvested in the rice fields to the drying chamber, etc. The belt conveyor used as a transfer mechanism to the outside of the tank is supported by the base of the adjustment mechanism, which is supported on the shaft at one end of the arm so as to be rotatable in the horizontal direction, in the left and right directions outside the tank body, and by the pin that supports the other end of the arm in the vertical direction. Since it is rotatably supported, the above-mentioned projecting projection angle to the outside of the tank main body can be freely changed to left and right and up and down, particularly to the left and right direction. As a result, a place where the truck bed cannot be linearly directed toward the drying chamber due to an obstacle between the drying chamber and the drying chamber, that is, the belt conveyor cannot be linearly drawn toward the drying chamber. Even at a place or the like, the grain can be transferred to the drying chamber by changing the pull-out protruding angle of the belt conveyor in the right or left direction avoiding obstacles.

Further, the belt conveyor is housed and placed below the transfer mechanism except for transferring the grains to the drying chamber or the like, whereby the device can be made compact. For example, the size of a truck or the like used for transportation from the rice field to the drying room or the like may be such that the tank body is mounted. As a result, the tank body can be transported to a place having a road width about the size of the tank body.

(Example) Hereinafter, an example of a grain tank according to the present invention will be described with reference to the drawings.

In this embodiment, the tank main body A, the feeding mechanism B, the belt conveyor C, the sliding mechanism D, and the adjusting mechanism E are adopted. The tank main body A stores the cut grain, and the metal plate, A synthetic resin plate or the like is formed in a box shape, and is provided with an inclined plate 1 that inclines toward both sides from the upper portions on both sides of the short side toward the bottom, and a rectifying plate 2 installed above the inclined plate 1.

The delivery mechanism B causes the grain stored in the tank body A to flow in one direction (the delivery end direction).
It is provided on the lower part of the inclined plate 1 and has a groove 3, a screw conveyor 4, and a motor 5. The groove 3 has a gutter shape, is fixed to the lower part of the inclined plate 1 and is arranged from one side of the longitudinal side of the tank body A to the other side thereof, and a hopper opened downward at its delivery end. A drop port 6 of the shape is provided. The screw conveyor 4 is housed and installed in the groove 3, and is supported by both side walls on the longitudinal side of the tank body A. The motor 5 is mounted in the space below the groove 3 in the tank main body A, and rotates the screw conveyor 4 via a belt 7.

The belt conveyor C transfers the grains that are fluidly delivered by the delivery mechanism B to the outside of the tank main body A, and corresponds to the above-described conventional transfer mechanism. The belt conveyor C is housed below the groove 3 along the groove 3 in the tank body A, and has a motor 8, a drive shaft 9 driven by the motor 8, and a driven shaft 10 facing the drive shaft. Belt 11 stretched between drive shaft 9 and driven shaft 10.
And a guide shaft 12 for supporting a belt 11 arranged at a constant interval between the drive shaft 9 and the driven shaft 10, and a skirt 13 made of a rubber material or the like for preventing overflow and scattering of grain from the belt 11. Become. Further, the belt conveyor C has a hanger 14 attached to its front end side in the stored state as shown in FIG.
The hook 15 is attached to the tank main body A so as to project to the outside of the tank main body A, so that it does not fly out unintentionally due to vibration during transportation by a truck or the like, and the stored state is maintained. is there.

The sliding mechanism D makes it possible to shift the belt conveyor C from the stored state shown in FIG. 1 to the pulled-out state shown in FIG. 2 or vice versa. The sliding mechanism D is a guide supported on the tank body A side below the drop port 6 with respect to a U-shaped rail 16 fixed along both sides of the belt conveyor C and opened to the outside. Assemble the wheel 17,
The guide wheel 17 is used as a support member to slide the rail 16 to move the belt conveyor C in and out. Since the guide wheel 17 is provided below the drop port 6, the end of the guide wheel 17 does not come off the drop port 6 when the belt conveyor C shown in FIG.

The adjusting mechanism E adjusts the protrusion angle of the belt conveyor C pulled out of the tank body A as shown in FIG.
As shown in the figure, it is adjusted in the vertical and horizontal directions. This adjusting mechanism E has a substantially U-shaped base 18 that opens upward.
The guide wheels 17 are attached to both side plates 18a of the
A bottom plate 18b for connecting the above is supported by a shaft 19 described later so as to be rotatable in the horizontal direction, and the other end (rear end) of the bottom frame 24 of the tank body A below the drop port 6 is vertically rotated by a pin 20. The shaft 19 is attached to one end (front end) of an movably mounted arm 21.
The lower side is pivotally attached by a pin 22, and the upper side is mounted so as to be capable of undulating and pivoting in the front-rear direction.

That is, the angle of protrusion of the belt conveyor C to the left and right is allowed by the horizontal rotation of the base 18 about the shaft 19 via the rail 16 and the guide wheel 17. Also, belt conveyor C
The projection angle of the rail 16, guide wheel 17
It is allowed by the vertical rotation of the base 18 and the arm 21 centering on the pin 20 via the. Further, the downward movement of the belt conveyor C causes the pin 22 to pass through the rail 16 and the guide wheel 17.
It is allowed by the rotation of the base 18 and the shaft 19 around the center.

Further, the adjusting mechanism E urges the shaft 19 rearward between the pin 20 that rotatably supports the arm 21 on the bottom frame 24 of the tank main body A and the upper side of the shaft 19. A coil spring 23 is installed to urge the shaft 19 which oscillates in the front-back direction about the fulcrum 22 so as to tilt it backward.
It is designed to prevent the belt conveyor C pulled out as shown in FIG. 2 by the spring force from moving downward due to its own weight.

That is, the coil spring 23 constantly pulls the shaft 19 backward by the spring force so that the shaft 19 supporting the base 18 on which the belt conveyor C is slidable forward and backward can be turned and rotated backward (rotated upright). Since it is supported so that it does not rotate sideways (see Fig. 5), the operator can
Care is taken so that the operator does not directly bear the weight of the belt conveyor C when the hanger 14 is grasped and pulled out of the tank body A.

Therefore, when the belt conveyor C is pulled out toward the drying room or the like, the burden on the operator due to the weight is greatly reduced, and the belt conveyor C can be pulled out smoothly and comfortably.

In the grain tank of the present embodiment configured as described above, after the grain harvested in the rice field is placed on the loading platform such as a truck and conveyed to the drying chamber or the like, the grain stored in the tank body A is transferred to the drying chamber or the like. When transferring, first remove the hooked state of the hanger 14 from the hook 15 and remove the belt conveyor C.
2 by using the sliding mechanism D, and by using the adjusting mechanism E in accordance with the withdrawal height and direction of the transfer location (the input hopper, etc.) such as the drying chamber, the vertical and horizontal withdrawal. Change the protrusion angle. At this time, since the weight of the belt conveyor C is supported by the coil spring 23, the operator can pull out the belt smoothly and smoothly.

After that, the feeding mechanism B is driven, and the grain stored in the tank body A is guided by the inclined plate 1 and the straightening plate 2 to guide the flow.
It is flow-delivered to the delivery end through and dropped from the drop port 6. Grain that has fallen from the drop port 6 is prevented from scattering by the hopper shape of the drop port 6 and placed on the belt 11 of the belt conveyor C, and is transferred from the tank body A to the drying chamber or the like by the drive of the belt conveyor C. become.

The transfer of grain by the belt conveyor C is sufficiently secured by opening the transfer cross section upward, and there is no member that becomes a flow resistance in the transfer line, so that it does not cause clogging or decrease in transfer speed. The grain of can be transferred promptly.

In addition, except the above-mentioned transfer, the belt conveyor C
Can be stored and placed below the bottom of the tank main body A, so that there is no problem such as the belt conveyor C protruding (jumping out) backward from the bed of the truck during transportation, and the device can be made compact.

As described above, in addition to the illustrated embodiment, the sliding mechanism D and the adjusting mechanism E may have a structure using a pivot or the like, and when the sliding mechanism D and the adjusting mechanism E are applied to a large apparatus, an air cylinder or the like is used to slide these. It is also possible to automatically control the moving mechanism D and the adjusting mechanism E.

(Effect of the device) Since the grain tank of the present invention is configured as described above,
The following operational effects are achieved.

． Since the belt conveyor is supported by the spring force of the coil spring that extends from the shaft that is attached to one end of the arm of the adjusting mechanism so as to be able to rotate back and forth, to the pin that pivotally connects the other end of the arm in the vertical direction, work the belt conveyor. When the operator himself holds it and pulls it out toward the drying room, the weight of the conveyor itself is not directly applied to the operator. Therefore, the burden on the operator is greatly reduced, and the belt conveyor can be smoothly and forcibly pulled out toward the drying room or the like.

． The belt conveyor is rotatably supported in the left and right directions outside the tank body by a base rotatably supported horizontally on the shaft of one end of the adjusting mechanism, and vertically by a pin supporting the other end of the arm. Therefore, the projecting projection angle to the outside of the tank main body can be freely changed to left and right and up and down, particularly to the left and right direction. Therefore, even in a place where the truck bed cannot be oriented straight toward the drying room due to obstacles between the drying room and the like,
The grain can be transferred to the drying chamber by changing the pull-out protruding angle of the belt conveyor in the right or left direction avoiding obstacles.

． Since the belt conveyor can be stored and placed below the transfer mechanism except for transferring the grains to the drying room or the like, the device can be made compact and the handling becomes simple.
