Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dryer configured to dry grains using hot air generated by a burner when the grains pass through a drying chamber.

In this type of dryer, the grains flowing down the drying room are collected from the grain conveyor at the bottom of the machine to the grain lifting device installed on the rear of the machine, and the grains are hoisted to the top of the machine by the grain lifting device. Generally, the grains are structured to flow down the drying chamber again, and the loading hopper for loading the grains into the machine body is provided so as to open toward the bottom of the grain lifting device. Alternatively, it is known that a grain harvesting hopper is provided on the left and right sides of the machine body so as to be stretched toward the grain harvesting hopper at the bottom of the drying room. When installing this dryer in a narrow barn, the burner installed at the bottom of the front of the machine on the opposite side from the grain lifting equipment must be spaced a minimum distance from the barn wall to prevent fires. Because of this, the grain hoisting equipment and staking hopper tend to be very close to the back wall of the barn, making it difficult to secure the space necessary for grain staking work.
Furthermore, the method of loading grain into a grain lifting device has the inconvenience of requiring a small amount of grain to be loaded over time depending on the grain lifting capacity of the grain lifting device.

Therefore, the present invention was proposed in order to solve this problem in view of the above-mentioned conventional problems. A tensioning hopper 16 is formed protruding outward from the fuselage 1 and is provided close to a corner on the front side of the fuselage 1 on the side of the burner 15, for tensioning grain into the fuselage 1. A suction fan 14 for discharging the hot air that has passed through the drying chamber 41 is provided on the back of the machine 1, and the grains collected in the grain collection hopper 3 at the bottom of the machine are transferred to the storage hoppers 2a and 2b at the top of the machine. It is an object of the present invention to provide a grain loading device for a dryer in which a grain hoisting device 7 for circulating grain hoisting is installed upright on the outside of the back part of a machine body 1. Therefore, by placing the suction fan close to the rear wall of the barn, for example, and installing the corner opposite to the stake hopper close to the side wall of the barn, a large work space can be created in front of the machine. This makes it possible to carry out the grain tensioning work, burner ignition, and adjustment work with a wide area at hand, while also being able to concentrate and efficiently carry out the work. It was designed to allow wind to be exhausted to the outside.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Funnel-shaped storage hoppers 2a, 2b, etc. are provided in the upper part of the body 1 of the dryer in parallel along the longitudinal direction of the body 1, and these storage hoppers 2

By rotating the drying chamber 4a...
... by adjusting the speed of grains flowing down the grain hopper 3.
The grains scraped to the rear of the machine body 1 by a grain collection conveyor 6 installed at the bottom of the machine are lifted to the top of the machine body 1 by a grain lifting device 7 installed upright on the rear surface of the machine body 1. The grains discharged from the spreading conveyor 8 extending from 7 to the upper center of the storage hopper 2a are spread by the spreading fan 9 into the storage hopper 2a, and also into the drying chambers 4a and 4b. A hot air outlet 11 is visible at the front of the air passage 10 surrounded by
a suction passage 1 formed by the outer plate of the
A suction tube opening 13 that communicates with the rear portions of the cylinders 2a and 12b is provided on the back of the fuselage 1, a suction fan 14 is provided inside the suction tube opening 13, and the combustion gas generated from the burner 15 provided in the hot air discharge tube opening 11 is used to generate hot air. The hot air is mixed with the outside air sucked from the rear end opening of the discharge tube port 11 and becomes hot air, which is sucked by the suction fan 14 and sent from the ventilation passage 10 to the left and right drying chambers 4a,
The grains flowing down in the drying chambers 4a and 4b across the drying chambers 4a and 4b are dried, and the exhaust gas that reaches the suction passages 12a and 12b is discharged to the atmosphere from the suction port 13 at the rear of the machine body 1 by the suction fan 14. To explain this based on an embodiment applied to a gravity flow type dryer, the tensioning hopper 16 has its upper part 16a located close to the left and right outer sides of the hot air outlet 11, and Open end 16b of hopper 16
is attached to the machine body 1 so as to be visible above the feeding start end 3a of the grain collecting hopper 3, and this chucking hopper 16 is attached to the outside in the left and right direction of the protruding part of the hot air discharge pipe opening 11 that protrudes outward from the front surface of the machine body 1. The upper parts 16a are formed so as to be lined up.

Here, if this tensioning hopper is removably attached to the fuselage 1 using a mounting bolt or a removable hinge, then if this tensioning hopper is removed after the tensioning work is completed, the hot air outlet Since the area around the burner 11 can be made wider, it becomes convenient for adjusting the burner 15 to adjust the firepower.

Also, although not shown, in some types of machines in which a burner and a hot air outlet are provided on the same side as the grain lifting device, the hopper is placed on the outside of the hot air outlet, similar to the above-mentioned embodiment. At the same time, the opening end of the lower part is exposed to the feeding start end of the grain hopper, so that it is possible to reduce the amount of unnecessary protrusion of this loading hopper from the front or rear of the machine, and also to directly feed the grain hopper. Since the grains can be staked in the grain, the time required for stake-out work can be shortened, as will be described later.

As mentioned above, the grain loading device according to the present invention has the following features:
A burner 15 is formed to protrude outward from the front of the fuselage 1.
Since the mounting hopper 16 is provided close to the corner of the front part of the machine body 1 on the side of the dryer, the overall length of the dryer can be reduced compared to conventional dryers. A stake-out hopper 16 is provided close to the corner on the front of the machine, and a suction fan 14 for exhausting air is provided on the back of the machine 1, so that it can be sucked into the rear wall of a barn, for example. While bringing the fan 14 closer, the stake-in hopper 16
By installing the opposite corner close to the side wall of the barn, a sufficiently large work space can be secured in front of the machine 1, and this work space can be used for ignition work and adjustment. In addition to making the work easier, the work of putting grain into the adjoining putting hopper 16 can be done intensively and efficiently together with the adjustment work of the burner 15. This made it possible to effectively utilize the work space of the department, and the barn could be used more widely without the need to increase the width or length of the machine body 1. Also, suction fan 1 is approaching the back wall of the barn.
The exhaust air from the 4 can be discharged to the outside easily and within a short distance, and the exhaust air does not return to the barn, resulting in an extremely hygienic and good work environment.

In the illustrated embodiment, the lower opening end 16b of the tensioning hopper 16 is exposed to the feeding start end 3a of the grain collecting hopper 3, so that the grain collecting hopper 3 has a large capacity and a large grain transporting capacity. By using the grain collection conveyor 6, the grain tacking operation by the tacking hopper 16 can be completed efficiently and in a short time.

Furthermore, since the lower opening end 16b of the tensioning hopper 16 is disposed below the hot air discharge tube opening 11, the front surface of the body 1 can be effectively utilized.

As described above, the grain loading device according to the present invention has excellent effects such as being able to effectively utilize the working space around the dryer.
