Description

[Detailed Description of the Invention] This invention relates to a charging device for rice husk, etc., which is configured in a trench excavator such as a screw auger.

. As is well known, for example, a trench digging machine called a screw auger is attached to the rear of an agricultural tractor, and a large amount of rice husks is buried in the bottom of the trench formed in the farmland by the trench machine to improve drainage. There is.

In this case, it is common to have one hopper at the rear of the auger, with the lower end of the hopper facing into the forming groove, so that a large amount of rice husks can be continuously dropped and fed.

However, since the hopper type mentioned above gradually narrows downward, it is easy to get clogged, especially when the rice husks are moist. This requires a worker to peck out the paddy, and a worker is needed for this purpose. Therefore, the operator of the tractor and the worker who carries the paddy bags arranged in advance and replenishes them into the hopper are required. Since a total of three workers are required, there will be waste, and if there are many workers, the work itself will be difficult to perform, and the hopper itself will be used for purposes such as securing capacity. Although the rice husks were light because they were located high up, they were large and had to be done quite frequently, making the task of replenishing the hoppers difficult and tiring.

This idea was devised to solve the above problems, and its purpose is to reduce the number of workers involved in burying rice husks, etc., and to make the replenishment work cheap and easy to carry. At the same time, even if the rice husk etc. is quite wet, it is possible to efficiently feed it into the trench without any concern, and this can be done at an extremely simple structure and at low cost without requiring a hopper. To provide a device for introducing drainage accelerators such as rice husks into a trench excavator, which has been devised to provide a drainage accelerator such as rice husks, etc.
In a device that is provided with left and right discharging forming plates facing each other and supplying a drainage accelerator such as rice husk into the forming groove through the space between the left and right discharging forming plates, the discharging forming plates are stretched outwardly. The point is that the overhang itself is configured as a stand for placing a bag for storing rice husks, etc.

The specific examples shown in the drawings will be described below.

Figures 1 and 2 show screw auger type trench excavator 1.
An example is shown in which the trench excavator 1 is equipped to be towed at the rear of an agricultural tractor 3 via a three-point linkage 2, and the trench excavator 1 is equipped with a gearbox 5 with a top mast 4 on its upper part, which receives PTO power from the tractor. This power forcibly rotates a vertical screw 6 provided at the bottom of the box 5.

The lower end of the screw 6 is supported by a semi-cylindrical trenching guide frame 7 that is fixed to the gear box 5 and surrounds the outer circumference of the rear half of the screw 6, and a support plate 8 that is also used for digging and protrudes from the lower end of the frame. In this way, trenches are dug to a constant depth.

At the rear of the trench guide frame 7, there are vertically elongated auxiliary frames 9 that are slightly narrower than the width of the Bogo ditch and are left and right opposite. 10.10' is installed.

Both molding plates 10 and 10' are formed by laminated plates in a dogleg shape, and have a lower half as a vertical linear guide part a and an upper half as an outwardly expanding presser guide part. , the straight guide part a is configured to protrude rearward from the auxiliary frame 9 and advance while slidingly contacting the opposing surface of the forming groove to regulate and control the swing of the groove excavator 1 itself. It has the function of holding down and removing the soil raked up on both sides of the ditch as shown by the imaginary line in Figure 2, and stabilizing it so that it does not fall again. Molded plate 10'
Further, at the upper end, there is formed a storage bag mounting stand C which integrally extends outward to the right side in a horizontal position, and this corresponds exactly to the upper side of the scraped out object.

This mounting table C is for placing the bags 11 containing rice husks one after another as shown in the imaginary line, and allowing the bags 11 to face into the groove along the inclined presser guide.

In addition to this, a hopper 13 with a shutter 12 may be provided, and in this case, the receiving port 14 may be located off to one side as shown by the imaginary line in FIG. 2 for convenience of work.

Therefore, in the above configuration, the rice husk bag 11 is disposed on the right side in the direction of travel, and as the vehicle progresses, it is sequentially carried and placed on the mounting table C.
The drain pipe 15 is directly poured from the bag 11 into the bottom of the formed groove n in which the drain pipe 15 is laid. This can be done, and since it can be directly charged without using the hopper 13, it can be carried out without any problems even if the rice husks themselves are quite wet. Therefore, there is no need for a worker to clear the blockage, and only one worker is required to carry and feed the rice husks. That's enough.

Of course, you are free to use the hopper 13 exclusively for dry rice husks for feeding, especially when installed together.
The mounting table C is effective when the hopper 13 is clogged or when the operator is tired.

In addition, the hopper 13 can hardly be used during rain, but it is effective even in this case.

This invention is as described above, and therefore, the number of workers involved in burying rice husks, etc. is further reduced, it is easier and more accurate to carry the rice husks, etc., and even if the rice husks, etc. are quite damp, Not only can it be buried efficiently, it can be implemented as an extremely lightweight and simple structure by using a molded plate without requiring a hopper, and it is inexpensive and has the advantage that it can be easily constructed even when towed by a small tractor.

Furthermore, as shown in Fig. 3, the hopper is constructed by forming a vertically penetrating hopper by forming a vertically penetrating hopper by using the left and right side walls of both the cylindrical plates 10 and 10' and a facing wall 16 that closes the space between them in the front and rear directions. In this case, if the shutter 17 is fully opened, the dry material can be fed without clogging as described above, but if the shutter 17 is opened to a certain extent, it can be used as a hopper to feed dry materials without clogging. In particular, since these are arranged at low positions, the stability of the trench excavator 1 as a whole is good, and even if it becomes clogged, it is extremely easy to clear it.

For example, in this case, the platform C can be configured to be detachable.

Furthermore, the trench excavator 1 may be of a crawler type or other type.
