Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a material supply device for mixing and supplying materials such as ready-mixed concrete, mortar, soil for improvement and greening.

[0002]

[Prior Art]

 For example, in the case of greening on flat or sloping ground after cutting mountains, a mixed material that mixes several kinds of materials such as seeds, soil for soil and fertilizer is supplied to the spraying equipment, and the mixed material supplied by the spraying equipment is supplied. Is sprayed onto flat or sloping ground.

However, conventionally, there has been no material supply device capable of continuously supplying the mixed material to the spraying device.

[0004]

[Problems to be solved by the device]

 As mentioned above, since there was no material supply device that could continuously supply the mixed material to the spraying device, efficient greening work could not be performed.

Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a material supply device capable of continuously supplying the mixed material together with the material mixing. .

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a pair of mixing chambers partitioned by partition walls, each of which has an independent material input port on the upper part and a lower part which is connected to each other by a communication part. A chamber, a material mixing section for mixing the materials put into the respective mixing chambers, and a rotor shaft capable of forward and reverse rotations, and a part of which faces the communication section such that the rotor axis is parallel to the partition wall. And a rotary feeder arranged below the partition wall. Further, the rotary feeder may have a plurality of blades protruding around the rotor shaft at equal angles, and the bottom portion between the blades may be formed substantially flat.

[0007]

[Action]

 The operation of the present invention thus constructed will be described.

When the material is supplied to one of the mixing chambers, the material mixing unit starts mixing the material. When the material is supplied to the other mixing chamber later than this, the material mixing section starts the mixing of the material. The materials that are sufficiently mixed in one of the mixing chambers are partially supplied to the communication section. When the rotor shaft is rotated from one mixing chamber to the other mixing chamber, the rotary feeder supplies downwardly the material that is sufficiently mixed in one mixing chamber and supplied to the communicating portion. In this case, the material supply amount can be controlled by controlling the rotation speed of the rotor shaft. By the time the well mixed material in one of the mixing chambers is exhausted, the material supplied to the other mixing chamber is well mixed. Then, when the rotor shaft is rotated in the reverse direction, the rotary feeder supplies the well mixed material in the other mixing chamber downward.

Further, the material can be easily dropped by forming the bottom portion between the blades to be substantially flat.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a usage state of a material supply apparatus 1 according to an embodiment of the present invention. The material supply device 1 mixes the material 3 input from a container bag (about 1200 kg) 2b suspended by a crane 2a of a truck 2 and supplies the material 3 to a spraying device 5 via a belt conveyor 4. .

The material 3 introduced into the material supply device 1 is, for example, a seed, soil, and fertilizer for greening, which are mixed in a predetermined ratio. Power is supplied from the generator 6 to the spraying device 5, the supply device 1, etc., compressed air is supplied to the spraying device 5 from the compressor 7, and the mixed material 3 ′ is cut by the pressure supply hose 8 into, for example, a sloping ground where a mountain is shaved. The greening work is done by spraying on F. The control panel 9 controls various parts such as the supply device 1 and the spraying device 5.

FIG. 2 is a cross-sectional view of the present supply device 1 as seen from the front side, and FIG. 3 is a cross-sectional view of the present supply device 1 as seen from the side direction. The supply device 1 includes a pair of mixing chambers 10 (10 a, 10 b), a material mixing section 20 arranged in each of the mixing chambers 10 a, 10 b, a rotary feeder 30, and a material mixing unit under the control of a control panel 9. It has a unit 20 and a drive unit 40 for driving the rotary feeder 30.

The pair of mixing chambers 10 are partitioned by a partition plate 11 serving as a central partition wall, each upper part is provided with an independent material charging port 12, and the lower parts are communicated with each other by a communication part 13. It has a structure.

In the material mixing section 20, a plurality of mixing blades 23 are fixed by an arm 22 to a rotating shaft 21 which is horizontally installed in the mixing chamber 10 substantially at the center.

The rotary feeder 30 includes a rotor shaft 31 that can be rotated forward and backward, a plurality of (in this example, four) blades 32 that project from the rotor shaft 31 at equal angles, and a root of the blade 32. And a housing 34 which is opened at the upper side and communicates with the communicating portion 13 to cover the rotor shaft 31, the blades 32, the connecting plate 33, and has a downwardly opened hole. The connecting plate 33 prevents the material 3 from entering the base of the blade 32 and makes it easy for the material 3 to drop downward. The buckets between the blades 32 have the same capacity. Further, the rotary feeder 30 is arranged so that a part of it faces the communication portion 13 so that the rotor shaft 31 is parallel to the partition plate 11 of the mixing chamber 10, and the rotary feeder 30 is arranged in the communication portion 13 at every predetermined rotation angle. It supplies a certain material 3 downward.

The drive unit 40 rotates the respective material mixing units 20 in opposite directions via the belt 41, and the mixing drive sources 42 and the rotor shaft 31 of the rotary feeder 30 in the normal or reverse direction. And a drive source 43 for supply.

The control panel 9 includes a mixing switch (not shown) that activates and deactivates the mixing drive source 42 of the drive unit 40, and a supply switch (not shown) that activates the supply drive source 43 of the drive unit 40. The rotary feeder 30 is provided with a knob (not shown) for setting the rotation direction and the rotation speed of the rotor shaft 31.

Next, the operation of the apparatus 1 of the embodiment having the above-mentioned configuration will be described with reference to FIGS. 4 to 6.

From the truck 2, for example, the unmixed material 3 is charged into the material charging port 12 of the left mixing chamber 10a. When the operator operates the mixing switch of the control panel 9 to activate the mixing driving source 42, the mixing driving source 42 drives the material mixing section 20. In the mixing chamber 10a on the left side, the unmixed material 3 is mixed by the material mixing section 20. While mixing is being performed in the left mixing chamber 10a, the unmixed material 3 is charged from the truck 2 into the material charging port 12 of the right mixing chamber 10a. Mixing is similarly started in the mixing chamber 10b on the right side.

Then, as shown in FIG. 4, the material 3 in the left mixing chamber 10a becomes a sufficiently mixed material 3 ', and the material 3 in the right mixing chamber 10b is not yet sufficiently mixed. The material 3 remains as it is, and the mixed material 3 ′ is supplied to the bucket toward the communicating portion 13.

Here, the operator operates the knob of the control panel 9 to rotate the rotor shaft 31 to the right a predetermined number of times, and further operates the supply switch to activate the supply drive source 43 of the drive unit 40. . The supply drive source 43 performs an operation of rotating the rotor shaft 31 of the rotary feeder 30 rightward a predetermined number of times to stop the rotor shaft 31. In the state where the rotor shaft 31 is rotated by 1/2, as shown in FIG. 5, the material 3'which was initially in the communication portion 13 drops. While the rotor shaft 31 is rotating clockwise, only the mixed material 3'in the left mixing chamber 10a is dropped. That is, when the rotor shaft 31 is rotated to the right from the state shown in FIG. 4, when the blades 32 pass through the communication part 13, the buckets that face the communication part 31 are already sufficiently mixed in the left mixing chamber 10a. The material 3 which has been filled with the mixed material 3 ′ that has been mixed and is not yet sufficiently mixed in the mixing chamber 10 b on the right side does not enter the bucket.

By the time the well-mixed material 3'in the left-side mixing chamber 10a is exhausted, the material 3 supplied to the right-side mixing chamber 10b is sufficiently mixed. Therefore, when the rotor shaft 31 is reversely rotated in the same manner as described above, the rotary feeder 30 drops the well-mixed material 3'in the right mixing chamber 10b downward.

The mixed material 3 ′ thus dropped from the rotary feeder 30 of the supply device 1 is supplied to the spraying device 5 by the belt conveyor 4. The spraying device 5 sprays the mixed material 3 ′ from the pressure-feeding hose 8 onto the sloped ground F, for example, where the mountain is shaved, by the compressed air supplied from the compressor 7 to perform the greening work.

According to the apparatus 1 of the embodiment as described above, the material in any of the mixing chambers can be freely supplied only by switching the rotation direction of the rotor shaft without providing a special supply switching valve or the like. Since the structure of the supply device 1 can be simplified and a fixed amount can be supplied only by controlling the rotation speed of the rotor shaft, the supply amount can be easily managed.

Further, while supplying the sufficiently mixed materials from one of the mixing chambers, the materials of the other mixing chamber can be mixed, and after the materials of the one mixing chamber are completely supplied, the rotor shaft It is possible to continuously mix and supply the materials, since the sufficiently mixed materials can be supplied in the other mixing chamber by switching the rotation direction of.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, the case of greening work was explained, but it can also be applied to the case of mixing and supplying materials such as ready-mixed concrete and mortar for protection work on rocks and roads.

Since the materials can be supplied in a predetermined amount, it is possible to provide a material supply device capable of mixing the materials and continuously supplying the mixed materials. Further, the material in any of the mixing chambers can be freely supplied only by switching the rotation direction of the rotor shaft without providing a special supply switching valve or the like, so that the structure of the supply device can be simplified.
