Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reciprocating rotary scraper conveyor having a main bucket cart and an auxiliary bucket cart.

In recent years, localized repair work on asphalt road surfaces has become more common, but when repairing the asphalt road surface, the waste material cut with road cutters etc. is carried off site, or when the waste is carried out during road surface cleaning. In such cases, a loading machine is required to load loading materials such as waste materials onto a transport machine such as a truck. The loading machine uses a pair of left and right blades or an auger (rotary drill) attached to its front end to scrape up loading materials such as waste materials from the outer end to the inner end, and transfers the loading materials inside. This device uses a scraper conveyor installed close to the end to scoop up the waste, transport it to the rear of a loading machine, and load it onto a transport machine such as a truck.

However, in the scraper conveyor used in the loading machine, a large number of buckets of the same type are fixed between a pair of endless chains placed opposite each other inside the casing, and the endless chains move the buckets in one direction inside the casing. The problem is that the capacity of each bucket is relatively small, and that there is a lot of waste left behind when scooping up waste materials with the buckets.
In order to clean the leftover waste to the desired degree, the current method is to either manually clean it using a bamboo duster, scoop, etc., or mechanically clean it using a road cleaning machine such as a motor sweeper. However, if a bamboo duster or the like is used, 2 to 3 people are required, and if a sweeper or the like is used, it becomes expensive. The biggest drawback is the disposal of waste materials.

In addition, when removing snow in cold, snowy regions, it is necessary to scoop a large amount of snow, and when collecting empty cans, etc., it is necessary to scoop a small amount, but this machine is used as a multipurpose machine that satisfies both of these requirements. There was no scraper conveyor that could do this.

The purpose of this invention is to solve the above-mentioned problems by providing a forward and reverse rotary scraper conveyor that can selectively use relatively large-capacity buckets and relatively small-capacity buckets for loading materials such as waste materials. This is what we are trying to provide.

In order to achieve this purpose, the forward and reverse rotary scraper conveyor according to the present invention, unlike conventional bucket carts, uses a bucket cart that integrates a relatively large-capacity main bucket cart and a relatively small-capacity auxiliary bucket cart back to back. When the amount of conveyance is large, the scraper conveyor is rotated in the forward direction and the main bucket is used, and when the amount of loaded materials such as waste materials is to be reduced, the conveyor is rotated in the reverse direction and the auxiliary bucket is used. This makes it possible to reduce time and effort.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a forward-reverse rotary scraper conveyor having a main bucket cart and an auxiliary bucket cart according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an outline of a blade-type loading machine 1, and the loading machine 1 is a self-propelled type. At the front end of the main body 2 of the loading machine, a pair of blades 3, 3 for scraping up loading materials such as waste materials and snow from the asphalt road surface is installed at a desired angle left and right by a hydraulic cylinder (not shown) or the like. It is attached so that it can be expanded. In order to scoop up the loading material scraped up by the pair of blades 3, 3, a scraper conveyor 4 is attached to the loading machine body 2 in close proximity to the inner ends of the pair of blades 3, 3. , and the scraper conveyor 4 is mounted at an angle to accommodate the transfer of the material to the belt conveyor 16.

As shown in FIGS. 3 to 5, the scraper conveyor 4 is connected to the loading machine main body 2 so as to be vertically movable, and a shaft 8 and a shaft 9 are provided inside a frame 5 and are opposed to each other. A pair of driving sprockets 6 and a pair of driven sprockets 7 are supported on shafts 8 and 9, respectively, and a pair of endless chains 10 are wound around the driving and driven sprockets 6, 7.
A large number of buckets 1, which will be described later by means of a shape holder 11,
2 are mounted at regular intervals, and when driven by a drive motor 13, the bucket 12 moves within the frame 5 through the drive sprocket 6 and the chain 10 in the forward and reverse directions (counterclockwise rotation of the driven sprocket 7 shown in FIG. 3). and clockwise direction).

A back plate 14 is fixed to the frame body 5 so as to extend diagonally along the slope of the scraper conveyor to prevent spillage when the bucket cart 12 moves in the reverse direction (clockwise rotation direction of the driven sprocket 7). A discharge port 15 is provided at the upper end of the back plate 14 , and a belt conveyor 16 is connected to the discharge port 15 . The loaded material A scooped upward by the scraper conveyor 4 is transferred to the belt conveyor 16 . It is then transported backwards and loaded onto a transport machine such as a truck from its rear end.

As shown in FIG. 5, the plurality of buckets 12 include a main bucket 12a with a relatively large capacity and an auxiliary bucket 12b with a relatively small capacity, which are integrally connected back to back, and the main bucket 12a is connected to an endless chain 10.
is formed such that it can be scooped in when the endless chain 10 rotates in the forward direction (rotation to the left) and can be reliably discharged from the discharge port 15, and the auxiliary bucket 12b can be scooped in when the endless chain 10 rotates in the reverse direction (rotation to the right). It is formed so that it can be reliably discharged through the discharge port 15. When rotating to the left, the main bucket 12a
A large amount of waste material is carried out by the auxiliary bucket 12b during clockwise rotation, and the waste material that cannot be removed at the final stage during counterclockwise rotation is scooped up. Also, when rotating to the left, it is possible to remove snow, and when rotating to the right, it is possible to collect empty cans, etc.

In this embodiment, the bucket tot 12 is exemplified as one in which the main bucket tot 12a and the auxiliary bucket tot 12b are integrally connected back to back, but the main bucket tot and the auxiliary bucket tot can also be separated from each other.

Next, the operation of the forward and reverse rotary scraper conveyor according to the present invention will be explained.

First, the loading machine itself is moved forward at low speed, and the lower end of the frame 5 of the scraper conveyor 4 is grounded on the road surface. Therefore, when the drive motor 13 is rotated to the left in FIG.
b also rotates to the left. The effective bucket during counterclockwise rotation is the main bucket 12a, and when the main bucket 12a reaches the lower surface a along the back plate 14, scooping in of waste material begins, and at point b, scooping in of waste material continues. At point c, the conveyance mode is entered, and the waste material is discharged to the discharge port 15 at the upper point d.

Since the main bucket 12a is required to scoop a large amount of waste material, the shape of the bucket is adapted to suit the nature of the waste material. The discharged waste material is conveyed rearward by a belt conveyor 16 and continuously loaded onto a dump truck or the like. The main bucket 12a and the auxiliary bucket 12b are grounded so that the remaining amount of waste material is minimized.

The effective bucket belt when the drive motor 13 rotates clockwise is the auxiliary bucket belt 12b, and the auxiliary bucket belt 12b descends along the endless chain 10, reverses at the driven sprocket 7, scoops up to the positions A to B, and cuts the back plate. 14. At this time, the back plate 14 and the auxiliary bucket 12b discharge the waste materials when passing the terminal end position N of the back plate 14.

That is, when rotating in the forward direction (rotating to the left), a large amount of waste material is scooped up by the relatively large-capacity main bucket 12a, maximizing the amount of waste material loaded within a unit time, and at the time of final loading, rotating in the reverse direction (rotating to the right) The remaining amount can be loaded to a minimum using the auxiliary bucket cart 12b.

Since the forward and reverse rotary scraper conveyor according to the present invention is constructed as described above, a large amount of waste material is discharged by the main bucket which works effectively when rotating in the forward direction, and works effectively when rotating in the reverse direction. By scooping up and discharging a small amount of leftover waste using the auxiliary bucket, it is possible to maximize the waste processing machine, reducing the labor of auxiliary workers for cleaning. It can be used as a multi-purpose machine, such as collecting empty cans by rotating in the opposite direction.
