Description

The present invention relates to, for example, a receiving hopper arranged at a receiving place in a cereal drying preparation facility such as a country elevator.

Conventionally, a receiving hopper for receiving raw materials to be stored in the facility has been provided at a receiving place in a grain drying preparation facility such as a country elevator. The consignment hopper generally includes a hopper body having a raw material introduction port that opens upward, and a counter that is erected in at least a part of the peripheral edge of the opening of the raw material introduction port, and is upward toward the raw material introduction port. The raw material to be input from the hopper is introduced into the hopper main body through the raw material introduction port while being guided by a tsuitate, and is temporarily stored inside the hopper main body before being transported to the downstream side of the facility.

By the way, at the time of receiving work, when the raw materials loaded on the truck bed or container are put into the raw material introduction port of the receiving hopper, the raw materials are scattered to the outside of the tsuitate and scattered on the floor surface of the receiving place. It may end up. In such a case, after the consignment worker scrapes the scattered raw materials using a dust collector and a broom, the collected raw materials must be re-injected from the upper opening of the counter to the raw material introduction port, which complicates the work. There was a problem that it was. In addition, when the receiving worker re-loads the raw material, the receiving worker approaches the upper opening of the suitate, so that it is necessary to stop the feeding of the raw material from the truck bed or the like into the raw material introduction port of the receiving hopper. There was also a problem that the efficiency of the receiving work was reduced.

In order to avoid these, for example, as in Patent Document 1, it is conceivable to re-load the raw materials scattered on the floor surface of the receiving yard into the receiving hopper without using dust collecting. A rectangular opening wide in the horizontal direction is formed in the lower portion of the side wall of the hopper body in the cargo handling hopper of Patent Document 1, and the lower end edge of the opening is positioned corresponding to the floor surface of the cargo receiving area. A bottom wall that tilts downward toward the lower end edge of the opening and an inclined plate that tilts downward from the upper end edge of the opening toward the inside of the hopper body are arranged near the opening inside the hopper body. The inclined plate is rotatable around a rotating rod extending along the upper end edge of the inclined plate. One end side of the rotating rod penetrates the side wall of the hopper body, and a pedal composed of a frame having a substantially L-shape when viewed from the opening side is attached to one end of the rotating rod. There is. Then, when the raw material to be input from the upper opening of the tsuitate is introduced into the hopper main body by a truck bed or the like, the inclined plate closes the opening and the raw material is transferred from the inside of the hopper main body to the outside of the hopper main body through the opening. While preventing it from overflowing, when the tilt plate is rotated upward by operating the pedal, the opening communicates with the inside of the hopper body, and in this state, the consignment worker uses a broom. Raw materials scattered on the floor of the cargo receiving area can be swept into the hopper body through the opening.

However, the structure for opening and closing the opening for refilling the raw material as in Patent Document 1 by rotating the inclined plate is complicated, increases the parts and assembly cost, and may easily cause the device to break down. Further, it is necessary to rotate the inclined plate every time the raw material scattered on the floor surface of the receiving place is re-loaded into the receiving hopper, which causes a problem of poor work efficiency.

The present invention has been made in view of these points, and an object of the present invention is to easily and efficiently re-load the raw materials scattered on the floor surface of the receiving yard during the receiving work into the receiving hopper. Moreover, it is an object of the present invention to provide a low-cost receiving hopper that is unlikely to break down even after repeated use.

In order to achieve the above object, the present invention forms an opening for re-injection of raw materials scattered on the floor surface of the receiving yard in the abutment of the receiving hopper, and at a position corresponding to the opening for re-injection inside the tsuitate. It is characterized in that a partition wall portion is provided.

Specifically, the hopper body having a raw material introduction port that opens upward and the raw material that is erected in at least a part of the peripheral edge of the opening of the raw material introduction port and is input from above toward the raw material introduction port are the raw materials. The following measures were taken for the consignment hopper, which was configured to introduce raw materials into the hopper body through the raw material introduction port, which was equipped with a counter to guide the raw material to the introduction port.

That is, in the first invention, one or more first openings formed in the lower part of the tsuitate and the lower edge portion is set to a height corresponding to the floor surface of the receiving place, and the first opening. A partition wall portion extending inward and downward from the upper edge portion so as to cover the opening region of the first opening portion and forming a passage for scattering raw materials between the upper edge portion and the first opening portion, and a partition wall portion of the partition wall portion. It is provided with a second opening formed between the extending end and the lower edge of the first opening and at a position corresponding to the raw material introduction port and communicating with the scattering raw material passage. It is characterized by that.

In the second invention, in the first invention, the partition wall portion includes an inclined wall portion having one end continuous with the upper edge portion of the first opening and extending obliquely downward toward the other end. It is characterized by including a vertical wall portion extending linearly downward from the other end of the inclined wall portion.

In the third invention, in the first or second invention, the extending end of the partition wall portion is set to the same position as the lower end edge portion of the first opening portion or at a position lower than the lower end edge portion. It is characterized by being done.

In the fourth invention, in any one of the first to third inventions, the first opening is provided between the first opening and the partition wall, and is fixed to the upper edge of the first opening. It is characterized by comprising a flexible sheet extending downward from the upper edge portion of the first opening so as to close the opening region of the first opening.

In the first invention, since the first opening whose lower end edge is at a height corresponding to the floor surface of the receiving place is formed at the lower part of the tsuitate, the receiving worker can use the raw materials scattered on the floor surface of the receiving place. It will be possible to sweep inward of the tsuitate through the first opening while collecting with a broom. The raw material swept inward through the first opening moves downward through the scattering raw material passage while being guided to the outer surface of the partition wall, passes through the second opening, and then the raw material. It is introduced inside the hopper body through the introduction port. In this way, it is not necessary to use dust collector for the re-loading work of the raw material scattered on the floor surface of the receiving place, so that the raw material scattered on the floor surface of the receiving place can be easily re-loaded into the hopper body during the receiving work. be able to. In addition, when the raw material is charged from the upper opening of the counter by a truck bed or the like and introduced into the hopper body, the raw material charged inside the counter is guided to the inner surface of the partition wall to introduce the raw material. It will be introduced inside the hopper body through the mouth. In this way, the partition wall portion can prevent the raw material located inside the tsuit from coming out from the first opening to the outside of the load receiving hopper. Further, at the time of re-loading the raw material scattered on the floor surface of the receiving place into the hopper main body, the operation of the receiving worker other than the work of sweeping with a broom such as rotating the inclined plate as in Patent Document 1 is eliminated, so that the receiving work is received. The worker can efficiently re-load the scattering raw material. In addition, since the structure of the part where the raw material is re-injected into the receiving hopper as in Patent Document 1 does not have a moving part, parts and assembly costs can be reduced, and even if the use is repeated, the device will break down. Occurrence can be reduced.

In the second invention, the raw material input from above the counter is smoothly guided to the raw material introduction port by the inclined surface of the inclined wall portion. Therefore, it is possible to prevent the inclined wall portion from hindering the smooth movement of the raw material input from above the counter, or to prevent the raw material from bouncing back and scattering to the outside of the counter due to the inclined wall portion. In addition, since the vertical wall part that is continuous with the inclined wall part has a shape that extends linearly up and down, the scattering raw material passage to the raw material introduction port inside the tsuitate is provided while making the scattering raw material passage the minimum necessary space. The area to be removed becomes a sufficiently large space, and the raw materials input from above the counter can be efficiently introduced into the hopper body.

In the third invention, since the first opening is located on the rear side with respect to the traveling direction of the raw material when the raw material input from above the counter is passing through the extending end of the partition wall portion, the counter is It is possible to prevent the raw material input from above from unexpectedly jumping out from the first opening to the outside of the load receiving hopper.

In the fourth invention, when the raw material on the floor of the receiving place collected by the broom is moved to the first opening, the flexible sheet bends toward the scattering raw material passage side so that the raw material enters the scattering raw material passage. become. On the other hand, during normal cargo receiving work, the flexible sheet closes the first opening, so that the raw material input from the upper opening of the tsuitate is surely prevented from coming out from the first opening to the outside of the receiving hopper. On the other hand, it is possible to prevent dust and the like scattered on the floor surface of the receiving place from entering the inside of the tsuitate through the first opening.

It is a perspective view which shows the cargo receiving hopper which concerns on Embodiment 1 of this invention. FIG. 5 is a cross-sectional view taken along the line II-II of FIG. It is a figure corresponding to FIG. 2 which concerns on Embodiment 2 of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiment is essentially merely an example.

<< Embodiment 1 of the invention >>
1 and 2 show a load receiving hopper 1 according to the first embodiment of the present invention. The receiving hopper 1 is a facility arranged in a receiving place for receiving the raw material 10 in a grain drying preparation facility such as a country elevator, and is made of a substantially rectangular parallelepiped metal embedded in a pit P1 on the floor surface F1 of the receiving place. A hopper main body 2 and a metal tsuitate 3 provided above the hopper main body 2 are provided, and a bucket elevator (not shown) is installed behind the hopper main body 2.

A rectangular raw material introduction port 2b that opens upward is provided on the upper portion of the hopper main body 2. A metal frame 2c extending in a grid pattern is assembled to the inside of the raw material introduction port 2b, and the raw material 10 is introduced into a storage portion 2a provided inside the hopper main body 2.

The abutment 3 is provided along the first wall portion 5 erected along the long side portion in front of the equipment at the opening peripheral edge of the raw material introduction port 2b and both short side portions on the equipment side at the opening peripheral edge of the raw material introduction port 2b. The space S1 above the raw material introduction port 2b is surrounded by the first wall portion 5 and both second wall portions 6 in a substantially U shape in a plan view. There is.

That is, the upright 3 is erected in at least a part of the peripheral edge of the opening of the raw material introduction port 2b, and guides the raw material 10 to be input from above the upright 3 toward the raw material introduction port 2b to the raw material introduction port 2b. It has become like.

At the lower part of the first wall portion 5, a plurality of rectangular first openings 5a communicating with the inside of the countersunk 3 are arranged side by side in the horizontal direction, and the lower end edge of each of the first openings 5a receives a load. The height is set to correspond to the floor surface F1.

A partition wall portion 7 is fixed to the inner surface of the first wall portion 5 so as to cover the opening region of the first opening portion 5a.

The partition wall portion 7 has one end continuous with the upper edge portion of the first opening 5a, while the inclined wall portion 7a extends obliquely downward toward the other end, and the other end of the inclined wall portion 7a. A vertical wall portion 7b extending linearly downward and a vertical wall portion 7b extending linearly downward from each side edge portion of the inclined wall portion 7a, and each side edge portion of the first opening 5a and each side of the vertical wall portion 7b. A pair of side wall portions 7c connecting the square edge portions are provided, and the extending end 7d of the partition wall portion 7 is at substantially the same position as the lower edge portion of the first opening portion 5a.

That is, the partition wall portion 7 extends from the upper edge portion of the first opening portion 5a to the inside and lower side of the first wall portion 5 to form a scattering raw material passage R1 between the partition wall portion 7 and the first opening portion 5a. The second opening 8 communicating with the scattering raw material passage R1 is located between the extending end 7d of the wall portion 7 and the lower edge of the first opening 5a and at a position corresponding to the raw material introduction port 2b. Is provided.

The bucket elevator (not shown) is arranged so that the housing portion on the upstream side of the bucket elevator (not shown) is along the long side portion behind the equipment at the peripheral edge of the opening of the raw material introduction port 2b.

The inside of the bucket elevator (not shown) communicates with the storage unit 2a of the hopper main body 2, and the raw material 10 introduced into the storage unit 2a is transported to the downstream side of the facility via the raw material introduction port 2b. It has become.

Next, the receiving operation to the receiving hopper 1 of the first embodiment of the present invention will be described in detail.

For example, when a truck (not shown) loaded with the raw material 10 on the loading platform arrives at the loading platform, the raw material 10 is thrown into the upper opening of the counter 3 in the receiving hopper 1 by tilting the loading platform or the like. Then, the raw material 10 charged inside the tsuitate 3 is introduced into the hopper main body 2 via the raw material introduction port 2b while being guided by the tsuitate 3. At this time, since the inner side surface of the partition wall portion 7 guides the raw material 10 to the raw material introduction port 2b and covers the first opening 5a, the raw material 10 located inside the counter 3 is the first opening. The partition wall portion 7 can prevent the load receiving hopper 1 from coming out from the 5a.

Further, since the inclined wall portion 7a of the partition wall portion 7 has a shape that extends obliquely downward, the raw material 10 input from above the countersunk 3 is smooth along the inclined surface of the inclined wall portion 7a. You will be guided to the raw material introduction port 2b. Therefore, it is possible to prevent the inclined wall portion 7a from hindering the smooth movement of the raw material 10 input from above the counterbore 3, or to prevent the raw material 10 from bouncing back and scattering to the outside of the counterbore 3 due to the inclined wall portion 7a. Can be done.

Further, since the vertical wall portion 7b continuous with the inclined wall portion 7a has a shape extending linearly in the vertical direction, the raw material introduced inside the counter 3 is introduced while keeping the above-mentioned scattering raw material passage R1 in the minimum necessary space. The area excluding the scattering raw material passage R1 up to the mouth 2b becomes a sufficiently wide space, and the raw material input from above the counter 3 can be efficiently introduced into the hopper main body 2.

Further, since the extending end 7d of the partition wall portion 7 is at substantially the same position as the lower edge portion of the first opening 5a, the raw material 10 input from above the countersunk 3 extends from the partition wall portion 7. The first opening 5a is located on the rear side with respect to the traveling direction of the raw material 10 when passing through the end 7d. Therefore, it is possible to prevent the raw material 10 to be input from above the counter 3 from unexpectedly jumping out from the first opening 5a to the outside of the load receiving hopper 1.

Next, the work of re-loading the raw material 10 scattered on the floor surface F1 of the receiving place into the receiving hopper 1 during the receiving work of the first embodiment of the present invention will be described in detail.

For example, when the raw material 10 is put into the upper opening of the countersunk 3 in the load receiving hopper 1, the raw material 10 may scatter to the outside of the countersunk 3 and scatter on the cargo receiving area floor surface F1. In such a case, the consignment worker collects the raw materials 10 scattered on the floor surface F1 of the consignment yard with a broom, and moves the collected raw materials 10 toward the first opening 5a as shown by the arrow X1 in FIG. Let me. Then, since the lower end edge of the first opening 5a is formed at the lower part of the tsuitate 3 at a height corresponding to the floor surface F1 of the receiving place, the collected raw material 10 is formed in the tsuitate 3 through the first opening 5a. Sweeped inward. The raw material 10 swept inward through the first opening 5a moves downward through the scattering raw material passage R1 while being guided by the outer surface of the partition wall portion 7, and also moves through the second opening 8. After passing through, it is introduced into the hopper main body 2 via the raw material introduction port 2b. As described above, since it is not necessary to use the dust collector for the re-injection work of the raw material 10 scattered on the receiving place floor surface F1, the raw material 10 scattered on the receiving place floor surface F1 during the receiving work is placed inside the hopper main body 2. Reloading can be done easily.

From the above, according to the first embodiment of the present invention, the raw material 10 scattered on the floor surface F1 of the receiving place during the receiving work can be easily recharged into the receiving hopper 1.

Further, at the time of re-loading the raw material 10 scattered on the floor surface F1 of the receiving place into the hopper main body 2, the operation of the receiving worker other than the operation of sweeping with a broom such as rotating the inclined plate as in Patent Document 1 is eliminated. Therefore, the consignee worker can efficiently re-load the scattering raw material 10.

Further, in the consignment hopper 1 of the first embodiment of the present invention, the structure of the portion where the raw material is re-injected into the consignment hopper as in Patent Document 1 does not have a movable portion, so that the parts and the assembly cost can be reduced. At the same time, it is possible to reduce the occurrence of device failure even after repeated use.

<< 2nd Embodiment of the Invention >>

Therefore, when the raw material 10 on the floor surface F1 of the receiving place collected by the broom is moved to the first opening 5a, the flexible sheet 9 bends toward the scattering raw material passage R1 as shown by the arrow Y1 in FIG. Then, the raw material enters the scattering raw material passage R1. On the other hand, during normal cargo receiving work, since the flexible sheet 9 closes the first opening 5a, the raw material 10 to be charged from the upper opening of the counter 3 comes out from the first opening 5a to the outside of the cargo receiving hopper 1. While it is possible to surely prevent it from being stored, it is possible to prevent dust and the like scattered on the floor surface F1 of the receiving place from entering the inside of the tsuitate 3 through the first opening 5a.

In the first and second embodiments of the present invention, the first opening 5a is provided in the first wall portion 5 of the tsuitate 3, but it may be provided in the second wall portion 6 of the tsuitate 3.

Further, in the first and second embodiments of the present invention, the abutment 3 is provided with a plurality of first openings 5a, but only one first opening 5a may be provided.

Further, in the first and second embodiments of the present invention, the first opening 5a formed in the strut 3 has a rectangular shape, but other opening shapes may be used as long as they communicate with the inside of the strut 3. ..

Further, in the first and second embodiments of the present invention, the extending end 7d of the partition wall portion 7 is at substantially the same position as the lower end edge portion of the first opening portion 5a, but the lower end edge of the first opening portion 5a. The configuration may be set at a position below the unit.

Further, in the first and second embodiments of the present invention, the cross-sectional shape of the partition wall portion 7 is a dogleg shape including an inclined inclined wall portion 7a and a vertical wall portion 7b extending vertically. The shape is not limited to the above, and may be, for example, a shape extending diagonally downward from the upper edge portion of the first opening 5a to the extending end 7d, or extending from the upper edge portion of the first opening 5a. The shape may be gently curved to the end 7d, and may be any other shape as long as the scattering raw material passage R1 is formed between the first opening 5a and the partition wall portion 7.

Further, in the second embodiment of the present invention, the flexible sheet 9 is formed of a rubber material, but the present invention is not limited to this, and for example, it may be formed of a resin material and is manufactured of a flexible material. Anything that has been done will do.

The present invention is suitable for, for example, a receiving hopper arranged at a receiving place in a cereal drying preparation facility such as a country elevator.
