Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hazard prevention body for a side tensioning device in a grain dryer, and in particular, to improve the safety of grain tensioning work in a grain dryer. This invention relates to a safety device for a side tensioning device in a machine.

[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 port of the grain lifting machine. Then, the grains to be dried, which are put into the hopper, are lifted up and conveyed to the upper central part of the dryer by the upper conveying means, and are 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 conveying means 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. The cycle is repeated, during which time the grain is dried.

[Problems to be solved by the invention] By the way, a long loading hopper is used at the upper edge of the loading port of the grain lifting machine of the grain dryer in order to increase the amount of grain input. . Moreover, a frame body for preventing danger and preventing intrusion of foreign matter is provided above the cross-feeding mechanism consisting of the screw conveyor of the side tensioning device. The size of the gap portion of the frame is variously set depending on the dimensions of the side tensioning device.

Furthermore, although it is generally necessary for safety to make the size of this gap as small as possible, if the gap is made extremely small, there is a risk that the grain will not flow into the cross-feeding mechanism. There is an inconvenience that the tensioning function of the tensioning device is degraded. Furthermore,
If the gap is made larger than necessary, there is a risk that the combine bag will be wedged into the cross-feeding mechanism, and it will also be possible to insert hands from both ends of the cross-feeding mechanism, creating a dangerous situation. It has the disadvantage of being large.

[Purpose of the invention] Therefore, in order to eliminate the above-mentioned inconvenience, the purpose of this invention is to provide a safety body that opens and closes the grain stacking opening at least at both ends of the stake hopper, and to open and close the grain stacking opening. By providing a biasing member that biases in the closing direction, it is possible to prevent hands or the combine bag from being bitten into the side tensioning device, there is no inconvenience that impairs the grain tensioning function, and the structure is simple. The object of the present invention is to realize a hazard prevention body for a side tensioning device in a grain dryer that can reduce costs.

[Means for solving the problem] In order to achieve this purpose, this invention installs a grain fryer on either the front or rear sides of the grain dryer, and also installs a long gutter on either the left or right sides. In a grain dryer, the gutter is installed horizontally, this gutter has a built-in cross-feeding mechanism for feeding grain to the loading port of the grain lifting machine, and a long loading hopper is installed in the upper part of the gutter. In the side tensioning device, at least both end portions of the tensioning hopper are provided with danger prevention bodies for opening and closing the grain tensioning opening to the gutter, and the danger prevention body is biased in a closing direction to close the opening. The present invention is characterized in that it is provided with a biasing member.

[Function] With the above-described configuration, when grain is put into the hopper for tensioning, grain pressure acts on the danger prevention body, and the danger prevention body is opened against the biasing force of the biasing member. By moving in the opening direction, the side tensioning device is loaded with grain. Furthermore, when grain is not put in, the danger prevention body is positioned in the open closed position due to the biasing force of the biasing member, which improves safety and eliminates the risk of impairing the tensioning function. Therefore, the cost can be reduced.

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

2 is installed horizontally and removably. Further, the gutter 12 has a built-in cross-feeding mechanism 14 consisting of a screw conveyor, as shown in FIG.
The structure is such that the grain to be dried is fed to the loading port 16. Further, on the upper part of the gutter 12, second and third
As shown in the figure, a long hopper 18 for tensioning is arranged, and the tip portion 1 of the hopper 18 is
The distance to 8a is, for example, approximately 45 cm or more. This constitutes the side tensioning device 20.

Further, at least both end portions of the hopper 18,
For example, near both ends, a danger prevention plate 24 is provided as a danger prevention body that opens and closes the opening 22 for filling grain into the gutter 12, and the upper end side of this danger prevention plate 24 is rotated toward the dryer 2 side. Can be installed freely. That is, the fixing plate 28 is attached to the upper end of the danger prevention plate 24 via the screw 26, and this fixing plate 28 is attached to the fixing tool 3.

Further, the danger prevention plate 24 is provided with a biasing member 32 made of a spring or the like that biases the grain loading opening 22 in the closing direction so as to close the grain loading opening 22 by the danger prevention plate 24. In detail, this biasing member 32
The danger prevention plate 24 is centered around the hinge 26.
The structure is such that it is biased to rotate upward, which is the opening closing direction.

2 is a transmission belt.

Next, the effect will be explained.

When loading grain into the circulating grain dryer 2, the grain is loaded, for example, from the grain input port 38 of the hopper 18 using a combine bag or a truck. Then, the grains pass through the hopper 18, reach the gutter 12, are conveyed by the cross-feeding mechanism 14, and are loaded into the grain lifting machine 10 through the loading port 16 of the grain lifting machine 10. Circulatory drying of grains is performed by the lifting function and the drying function of the dryer 2.

Further, when a large amount of grain is thrown into the hopper 18, the grain is spread in the longitudinal direction of the hopper 18, and the grain is stacked on the danger prevention plate 24.
At this time, the grain pressure consisting of the weight of the grain acts on the danger prevention plate 24, and the danger prevention plate 24 moves downward, which is the opening opening direction, against the urging force of the urging member 32.
is rotated, and the grains fall into the gutter 12.

As a result, the danger prevention plate can be opened as the grain pressure increases, preventing hands and combine bags from getting wedged in the cross-feeding mechanism of the side tensioning device, and improving the safety of grain tensioning work. can be improved.

In addition, there is no inconvenience that the safety plate impairs the grain tensioning function, and the grain tensioning work can be carried out as efficiently as in the past.
