Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a tensioning device for a grain dryer, and in particular aims to improve the efficiency of tensioning work by facilitating grain tensioning, and to improve the tensioning work efficiency. The present invention relates to a tensioning device for a grain dryer that can improve versatility.

[Prior Art] A grain dryer, for example, a circulating grain dryer, is equipped with a grain lifting machine, and a grain loading hopper is provided at a loading opening of the grain lifting machine. Then, the grain to be dried, which is put into the hopper, is lifted up and conveyed to the upper central part of the dryer by the upper conveyance mechanism, and is evenly dropped into the storage section, and then sent to the grain collection section through the drying section. The grain is guided, transported by a lower conveyance mechanism toward a grain lifting machine installed on either the front or rear sides of the dryer, and then lifted up by the grain lifting machine again. During this cycle, the grain is dried.

A loading device in which a hopper is attached to a loading port of a dryer is disclosed, for example, in Japanese Utility Model Application Publication No. 105895/1983. The tensioning device described in this publication has a lid pivotally attached to a hopper attached to a dryer, and the lid covers the supply port of the hopper during drying, and the lid is folded to serve as a loading platform when loading grain. It is.

[Problems that the invention aims to solve] However, in this staking device, the input port of the hopper is at a high position, and the grain must be fed from a high place, which requires a great deal of labor and reduces the staking work efficiency. In addition, although the lid also serves as a loading platform, only a portion of the loading platform is attached to one side of the hopper, making it difficult to carry heavy items such as combine bags. It is virtually impossible to load the grain, and furthermore, if the grain is stored in a grain bag, etc., the grain must be replaced with another small bag, making it impossible to carry out stakeout work as it is. There was an inconvenience in that the grain storage bag restricted the stakeout work.

[Purpose of the invention] Therefore, this invention eliminates the above-mentioned inconveniences, allows grain to be efficiently and easily staked at a low position, greatly reducing the labor involved, and eliminates the constraints of grain holding bags. This invention relates to a tensioning device for a grain dryer.

[Means for Solving the Problems] In order to accomplish this purpose, this invention consists of an input port provided in a cross-feeding mechanism that connects the grain collection section of the grain dryer and the lower part of the grain lifting machine, and the input port. A belt conveyor whose conveyance end is connected to a rotating belt and which conveys the grains supplied on the rotating belt and is input into the input port, and a front cover formed on the side opposite to the input port of the belt conveyor to support the belt. One side of the belt conveyor is pivotally mounted substantially parallel to the rotation axis of the belt conveyor, and is rotatable within the range of the front and upper surfaces of the belt conveyor;
a cargo receiving stand having legs rotatably provided on the opposite side so as to support the opposite side at a predetermined height with respect to the floor; and a side plate standing upright along the conveyance direction of the belt conveyor. and a locking member for fixing the load receiving platform in a vertical state to the side plate.

[Function] According to the configuration of this invention, when carrying out tensioning work, the tensioning device is connected to the lower conveyance path at the bottom of the grain collection section of the dryer, and if the grain storage bag is a combine bag, for example, the grain receiving bag is The stand is installed horizontally or on the floor, and the combine bag is placed on the receiving stand or on the floor. Then, by driving the conveyance mechanism of the loading device and loading grain from the combine bag into the loading port, the grain is loaded into the lower conveyance path of the dryer by the conveyance mechanism. Furthermore, if the grain storage bag is a grain bag, for example, if the loading platform is set up vertically, this loading platform is fixed to the tensioning device, and the grain is introduced from above the loading port, the grain will be stretched onto the lower conveyance path in the same manner as above. be included.

[Example of the invention] Hereinafter, an example of the invention will be described in detail and specifically based on the drawings.

1 to 5 show a first embodiment of this invention. In the figure, 1 is a grain dryer. This grain dryer 1 consists of a storage section 2, a drying section 3, and a grain collecting section 4, and has a grain lifting machine 5. This grain lifting machine 5 lifts the grains conveyed to the lower part of the grain lifting machine 5 to the upper part of the grain dryer 1 and conveys them into the storage section 2. The grains flowing down from the storage section 2 are dried in the drying section 3 by the hot air ventilation effect of the hot air generator 6 and the exhaust fan 7, and are guided to the grain collecting section 4. The grains are then lifted again by the grain lifting machine 5 and the circulation is repeated, during which time the grains are dried.

The grain collecting section 4 includes a lower screw conveyor 8 disposed in the front and rear direction of the grain dryer 1 and on both sides.
A vertical transport mechanism 9 is provided. The lower screw conveyor 8 is operated by a motor (not shown) and conveys the grains flowing down from the drying section 3 to the cross-feeding mechanism 10. This cross-feeding mechanism 10 includes a cross-feeding screw conveyor 11 and a case 12 surrounding the cross-feeding screw conveyor 11. The cross-feeding screw conveyor 11 and the case 12 are arranged, for example, at the front of the grain dryer 1 in the left-right direction. The grains conveyed by the lower screw conveyor 8 are transferred to a lift installed at one corner of the front surface of the grain dryer 1 by means of a horizontal screw conveyor 11 operated by a motor (not shown). The grain is transferred to the lower part of the grain machine 5.

In the upper part of the case 12 of the cross-feeding mechanism 10, an input port 13 is formed into which the suspended grain is input.
This inlet 13 is connected to the case 1 as shown in FIG.
It is formed to have a predetermined length L in the longitudinal direction of the case 12, for example up to the vicinity of one of the lower screw conveyors 8, and a predetermined width W in the direction orthogonal to the longitudinal direction of the case 12.

A loading device 14 for loading grain is connected to the input port 13. This tensioning device 14 includes, for example, a belt conveyor 15 having a width corresponding to a predetermined length L of the input port 13, and side plates 16, 16 erected on both sides along the belt conveyor 15.
, scattering prevention plates 17 , 17 erected on the upper surfaces of the side plates 16 , 16 , and a front cover 1 covering the front surface.
8, and a rear cover 19 that covers the rear upper surface and back surface.

A loading platform 20 is provided on the front cover 18. This loading platform 20 has a rear end 20a rotatably connected to the front end of the front cover 18 via a hinge 21, and a U-shape made of pipe material on the lower surface of the front end 20b of the loading platform 20. A shaped leg 22 is arranged so that its base end can be rotated, and this leg 22 can be rotated in the direction B in the same figure while the loading platform 20 is slightly rotated in the direction A in FIG. 3. Therefore, it is adapted to be accommodated on the back surface of the cargo receiving stand 20.

Further, the load receiving platform 20 accommodates the legs 22 on its back side, rotates in the direction A in FIG. For example, the cargo receiving platform 20 is erected substantially vertically, and in this state, the cargo receiving platform 20 also serves as a scattering prevention plate. (Status of ○A in Figure 3). The front end 20b of the loading platform 20 also rotates in the direction B in FIG.
can also be brought into contact with the floor (state shown in Figure 3). Furthermore, the loading platform 20 can also serve as a cover for the loading port 23 by rotating it in the direction C in FIG. 3 and storing it in the loading port 23 section.

In the figure, 24 is a rear plate. This rear plate body 24
serves as a scattering prevention plate and a lid, and is formed to be smaller in width than the cargo receiving platform 20, and one end is rotatably attached to the front end of the rear cover 19 by a hinge 25, and is used for loading grain. Sometimes it is rotated backwards and fixed at the position shown in ○D in Figure 3 to act as a scattering prevention plate. In addition, when the tensioning device is not in use, it acts as a lid by rotating forward and abutting the upper surfaces of the side plates 16, 16, and covers the entire tensioning port 23 of the tensioning device 14 together with the cargo receiving platform 20. (Situation shown in Figure 3).

The surface area of the cargo receiving platform 20 is made larger than the rear plate 24 because the tensioning side of the tensioning device 14 main body is lowered, and when grain tensioning is carried out using a gran bag or the like described later, the grains are placed on the tensioning side. This is to prevent it from flying off easily.

The belt conveyor 15 consists of a flat belt 25 and a pair of support rollers 26a, 26b, and conveys the pitched grain in the direction of arrow F shown in FIG. This belt conveyor 15 is driven and controlled by a drive motor 27 provided in the grain dryer 1. That is, the drive motor 27 is connected to a double pulley 29 via a first belt 28, and this double pulley 29 is connected to a drive shaft 31 of the support roller 26a via a second belt 30.
The drive pulley 32 is loosely fitted to the drive pulley 32.
A clutch mechanism 33 is attached to the drive shaft 31 for transmitting the rotation of the motor 27 to the flat belt 25.
is provided. As shown in FIG. 4, this clutch mechanism 33 has an operating lever 35 and a clutch 36 that is movable in directions D and E in FIG.
When the clutch 36 is operated to the "on" side, the clutch 36 moves in the direction D in the figure, engages with the clutch portion 37 of the drive pulley 32, and rotates the motor 27 so that the first belt 28, 2

2. It is transmitted via the clutch 36, the support roller 26a rotates, and the flat belt 25 rotates.

Further, on the surface of the endless flat belt 25 of the belt conveyor 15, a plurality of belts (for example, 10 to 20 The rods 38 of the book are attached at equal intervals. In this case, the height of 棧38 is 20
30 mm, the interval is 70 to 150 mm, and the driving speed of the flat belt 25 by the motor is 0.1 to 1.0 m/sec, it has been experimentally found that the tensioning efficiency is optimal.

The positional relationship between the flat belt 25 and the cross-feeding device 10 of the grain dryer, that is, the double pulley 29, is as shown in FIG. It is arranged so as to be on the feeding device 10 side (that is, on the grain dryer 1 side). Thereby, even if the speed of the flat belt 25 decreases, the grain can be prevented from returning to the tensioning device side. A rubber plate (not shown) is attached to a hole 42 (see FIG. 5) provided in the right cover of the tensioning device 14 through which the operating lever 35 moves, and this rubber plate has a sag-like cut. This ensures safety by preventing hands from entering the hole 42 without interfering with the movement of the operating lever 35.

5 so as not to interfere with the drive. Further, reference numeral 41 in the figure is a leg that supports the tensioning device.

Hereinafter, the effects of the embodiments of this invention will be explained.

Grain circulated within the grain dryer 1 is transported to a drying section 3.
and flows down onto the lower screw conveyors 8, 8. The above-mentioned grains are fed to the side of the cross-transfer mechanism 10 by the lower screw conveyors 8, 8, further transferred to the lower side of the grain lifting machine 5 by the cross-screw conveyor 11, and fried again. It is hoisted up by aircraft 5.

Next, when loading grain into the grain dryer 1,
The belt conveyor 15 is operated by rotationally driving the drive motor 27. If the grain storage bag can be held by hand, such as a combine harvester bag, the receiving platform 20 is installed horizontally,
Either place the combine bag on the loading platform 20 and feed the grain onto the belt conveyor 15, or rotate the loading platform 20 toward the floor so that the front end 20b is in contact with the floor, and in this state, combine If the bag is placed on the floor, the combine bag is tilted toward the tensioning device, and the grain is thrown onto the belt conveyor 15, the grain is conveyed to the grain dryer 1 side by the belt conveyor 15, and the grain is transferred to the grain dryer 1 side by the belt conveyor 15. The grains are put into the case 12 and conveyed to the lower part of the grain lifting machine 5 by the horizontal screw conveyor 11.

In addition, for example, if the grain storage bag is large like grain bag, first
2 is accommodated on the back side thereof, and the cargo receiving stand 20
The tensioning device 1 is rotated backward and held in a substantially vertical position.
The grain bag is fixed and held on the scattering prevention plates 17, 17 of No. 4 by a locking member, and then lifted by a lift or the like and set on the belt conveyor 15. In this state, the mouth of the grain bag is opened and the grains are dropped onto the belt conveyor 15. Then, the grain is conveyed to the lower part of the grain lifting machine 5 in the same manner as described above. In this case, since the surface area of the loading platform 20 is formed large,
The upper end of the loading platform 20 when set up is in a high position, and even if the loading side is in a low position, the loaded grain will not scatter forward.

As a result, the staking work can be performed on the floor or on the loading platform 20 which is low in height from the floor surface, so the staking work can be performed at a low position, and the staking work efficiency and usability can be improved. In addition, since the cargo receiving platform 20 can also serve as a scattering prevention plate, it is possible to perform stakeout work using large grain storage bags such as grain bags without installing new parts.
In addition to improving the versatility of staking work, when the loading platform 20 is installed and used on the floor, it closes the opening at the lower front of the loading platform 20 or the staking device.
It is possible to prevent air that does not contribute to drying from being inhaled and to prevent scattered grains from entering the lower part of the tensioning device. Furthermore, since the loading platform 20 can also be used as a lid when not in use, it is possible to prevent debris, dust, etc. from entering the belt conveyor 15 and rats from entering the belt conveyor 15 when not in use without providing any new parts.

In the above embodiment, the belt conveyor 15 of the tensioning device 14 is driven from the tensioning side to the input port 23 side of the grain dryer 1, but this invention is not limited to this in any way. For example, a belt conveyor driven in the left-right direction and a screw conveyor driven in a direction perpendicular to this belt conveyor are built into the tensioning device, and the tip of the screw conveyor is connected to the lower part of the grain lifting machine 5. death,
It is also possible to use a belt conveyor and a screw conveyor to tension the grains, and the shape of the tensioning device can be modified in various ways.

Furthermore, in each of the above embodiments, the legs of the loading platform are rotatably attached to the back surface of the loading platform, and when used as a scattering prevention plate, the legs are housed in the back surface of the loading platform. , the legs may be removably disposed on the loading platform so that they also serve as a scattering prevention plate when removed.Furthermore, in the above embodiment, the plane area of the loading platform is the area of the rear plate. Although it is larger (approximately twice as large), it may be made so that it has approximately the same height as the left and right scattering prevention plates of the tensioning device main body, for example.

[Effects of the invention] Since it is constructed as described in detail above, the grain dryer tensioning device according to this invention has the following effects. Grain can be staked at a low position, improving stakeout work efficiency. Since the loading platform is used as a scattering prevention plate without the need for new parts, highly versatile stakeout work is possible. Furthermore, the loading platform can also be used as a lid to prevent debris, dust, etc., or rats from entering the loading port.
