Abstract

PURPOSE:To make residue on a receiving pan so as to be easily taken out, by setting up the receiving pan retractably in an opening part at the lower end of a lifting vase, while linking a vertical motion of a wheel body at the lower side of an endless belt provided with plural scoop bodies with movements of the receiving pan. CONSTITUTION:At the time of taking out residual grains after drying work for grains and the like, first of all, a handle A of a receiving pan 4 is gripped, pulled toward an arrow and then the receiving pan 4 is slidden in a horizontal direction along guide rails 12 of a lifting case 2. At the time, since an actuating pin 17 comes into contact with an end face of a notch groove 16 of an actuating arm 15 and drawn nearer to a tension direction, an upper and part of the actuating arm 15 is also moved upward centering on a pin 20, causing a fulcrum shaft 13 to move upward along a guide groove 14. And, when the fulcrum shaft 13 reaches to an upper end of the guide groove 14, tension in an endless belt 8 by the lower wheel body 7 is relieved to some extent and the endless belt 8 is thus freed for motion. Therefore, the receiving pan 4 is in no case subjected to resistance of each scoop body 5 and the wheel body 7, thus residual grains on the receiving pan 4 can be easily taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevating device having a pumping body that pumps up objects to be pumped supplied into an elevating case. It is an object of the present invention to provide a residue removal device that can easily remove remaining residue.

If this kind of lifting device has a structure in which a tray is installed at the bottom of the lifting case, and the residue is taken out of the machine by inserting and removing the tray, the case body can be turned sideways and the bottom removed each time. Although it is simpler than the one that is disassembled and raised, if the entire tray is not removed, some residue may be left behind.

Further, if a removable shutter is provided at the bottom of the elevating case, most of the residue can be removed, but when the bottom is close to the ground, cleaning and collecting the residue takes time and effort.

In order to solve the above problem, the present invention takes the following technical measures. That is, there is a lifting case (2) formed in a box shape with an opening (1) at the lower end, and a receiving part (3) communicating with the opening (1), which can be inserted into and removed from the case (2). The two-side transport body (6) and the case (2) are arranged with saucers (4) arranged above and below, placed inside the elevating case (2), and rotatably mounted on the upper end of the case (2). An endless band (8) is rotatably mounted on a shaft at the lower end, and is wound around a lower wheel body (7) which can be moved in two directions so that the lifting body (5) can retract the inner thread of the lifting case (2). When the lower transport body (7) is located on the upward movement side, the mJ marking tray (4) is on the extraction side, and when the lower wheel body (7) is on the downward movement side, it is on the insertion side. The structure of the residue removal device in the lifting device is such that the movement of the saucer (4) and the vertical movement of the lower wheel body (7) are related to each other.

Such a configuration provides the following technical effects unique to this invention. That is, since the pumping body (5) enters into the receiving part (3) of the receiving tray (4) and pumps up the object when the lower end is rotated, the pumping efficiency is high and the amount of material remaining on the receiving tray (4) is improved. You can reduce things. On top of that,
When taking out the residue, move the pumping body (5) to the lifting case (
2), so when the tray (4) is pulled out, it can be pulled out without being blocked by the pumping body (5) or the lower wheel body (7). Lifting device (2) that easily lifts the remaining materials left on the top.
It can be taken outside.

Furthermore, since the saucer (4) can be taken out even if its lower surface is close to the ground, the effort required for cleaning etc. can be significantly reduced.

Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings.

First, to explain its configuration, the grain dryer (9)
is a circulation type, and a grain storage chamber is provided at the top of the dryer, and a pair of left and right drying chambers that are elongated in the front and back are connected to each other at the bottom, and the lower end of each drying chamber has a low rotation speed. A rotary droop is installed so that grains from the drying room are fed out little by little into the grain collection room below. The left and right side walls of both drying chambers are each made of a mesh or a perforated plate, so that the drying chamber can be ventilated from side to side. The hollow chamber formed between the left and right drying chambers (5) is configured as a hot air chamber, and the drying air created by mixing the hot air from the burner 00 and the suction air from the outside air by the suction fan is uniformly distributed between each drying chamber. The supply is made to pass through the drying chamber. Therefore, while the grains flow down from the drying chamber to the grain collection chamber, they are subjected to a drying effect by this drying air. Further, the outer spaces of each drying chamber are communicated with each other to form an exhaust chamber, and the hot air passing through the drying chamber is collected and discharged to the outside of the machine by a suction fan.

In addition, a lower helix is installed in the lower part of the grain collection room facing forward and backward, and after transferring the dried grains to one side, the grains are lifted upward by a lifting device αυ, and then The grains are fed into the center of the upper part of the grain storage chamber in a helical manner and supplied to the diffusion ring via a rotatably mounted diffuser.

The elevating device 0) consists of an elevating case (2) with open upper and lower ends, an upper wheel body (6) and a lower wheel body ( 7) and pumping bodies (5) are arranged at predetermined intervals to
) (7) and an endless belt (8) wrapped around it.

The saucer (4) has a receiving portion (3) that communicates with the opening (1), the front, left, right, and bottom portions are closed with plates, and the upper ends of the front and rear surfaces are each shaped like a horizontal U-shape. A guide rail is formed by bending the front and rear lower end surfaces of the elevating case (2) outward (the guide rail is configured so that it can be slid freely in and out. This is the left-right direction, that is, the direction perpendicular to the axial direction of the support shaft α of the lower transport body (7).The support shaft 03 is arranged in an arc shape in the vertical direction on the front and rear surfaces of the lifting case (2). It is constructed so that it can move up and down along the drilled guide groove α→, and the lower end of this guide groove α is used to raise the pumping body ( 5) Provided on the free end side or in a position close to the top surface of the bottom of the saucer (4), and the upper end of the guide groove 0 is provided on the free end side of the pumping body (5) or in a position retracted into the lifting case (2). ing.

0υ is formed into a key shape, the middle part is rotatably connected to the elevating case (2) via the pin (1), the upper end is pivotally connected to the support shaft (to), and the lower end is U-shaped notch groove α
The actuating arm is formed by forming a groove 0119 with the groove 0119 projecting outward from the saucer (4) and fitting into the actuating bin a. It is set up. And the operating arm 0υ is the ammunition 08)
Therefore, the mJ support shaft α is constantly being pulled to move toward the lower end of the guide groove 0.

Next, its effect will be explained. First, during grain frying, when you hold the handle of the saucer (4) and push the saucer (4) to the right side (that is, the insertion side), the operating pin Q71 comes into contact with the operating arm 00, and the lower end moves in the same direction. push.

Then, the upper end of the actuating arm 0Q rotates downward around the pin (A), but at this time, in conjunction with this rotation, the support shaft 04 is moved downward along the guide groove (14). , the lower transponder (7) is provided with an endless band (8). Then, when each rotating part is driven, the endless band (8) moves to the upper transport body (6) on the drive side.
) and the driven side lower wheel (7) rotate in the same direction as these wheels (6) and (7), so that the flow from the supply hopper 0υ into the lower part of the lifting case (2) The supplied grains are pumped up by a pumping body (5) pulled by the endless band (8) and fried to the transport start side of an upper helix installed at the upper part of the grain storage chamber of the main body of the dryer (9). Ru. When this pumping body (5) rotates along the outer periphery of the lower transport body (7) and reaches the lowest end, it is close to the bottom upper surface of the saucer (4).
Therefore, it becomes possible to pump up the grains accumulated in the receiving part (3) from the lower layer, reducing the amount of remaining grains and improving the grain frying performance.

Next, a case will be described in which the remaining grains (residues) are taken out after finishing the grain drying operation. First, the worker places the saucer (4)
When the handle (A) is grasped and pulled toward the supply hopper ■υ, this tray (4) slides horizontally along the guide rail 02 of the lifting case (2). During this sliding, the actuating pin α force comes into contact with the end face of the notch groove 0O of the actuating arm θ0 and pulls it in the pulling direction, so that the actuating arm α
The upper end of 0 is also moved upward around the pin (A), and the support shaft α■ is moved upward along the guide groove αY. When the bullet (18) passes over the fulcrum of the pin (A) during this upward movement, the operating arm 0υ is moved by the tensile force of the bullet 08) until the support shaft 0 crease contacts the upper end of the guide groove 0. Rotate further upwards. In this way, when the support shaft 03 reaches the end of the guide groove Oa,
The endless belt (8) can move freely until the tension on the endless belt (8) due to the lower transport body (7) is released and the pumping body (5) can be retracted into the lifting case (2). When the tray (4) is pulled out, the tray (4) can be smoothly taken out without being subjected to any resistance or obstruction by the pumping body (5) or the lower transport body (7).

Therefore, the remaining grains on the tray (4) can be collected and processed outside the machine, reducing time and effort. For example, when drying different types of grains subsequently, the drying efficiency can be improved. I can figure it out.
