Description

  The present invention relates to a spraying device, and more particularly to a spraying device that can be attached to and detached from a transport vehicle with a dump function and that can prevent a cross-linking phenomenon due to the influence of moisture content of an object to be sprayed.

  2. Description of the Related Art Conventionally, various fertilizer spraying vehicles and spraying devices have been proposed for spraying materials to be spread, particularly compost, fertilizers, and the like while traveling in a field. Various spraying devices for antifreezing agents on road surfaces in winter have also been proposed.

  For example, a fertilizer is equipped with an impeller at the rear end in the dump box of a dump vehicle, and the impeller is driven by a drive source on the vehicle body side via an intermediate drive wheel positioned on the axis of the load box dump shaft. There is a spreader (see Patent Document 1).

  Further, there has also been proposed a bridging prevention device in a fertilizer spraying device that is provided with two or more shafts with protruding wings that are not in contact with each other at the lower part of the tank and rotated in the right direction and the left direction, respectively (Patent Document 2). reference.).

  Furthermore, in the container base, two screws, a supply screw in the container for the object to be sprayed and a discharge screw for the object to be sprayed, are in the opposite conveying direction, and the discharge screw is parallel to the supply screw. There is also a spraying device provided below the side (see Patent Document 3).

  However, the technique of the above-mentioned utility model registration document 1 is connected to the drive source of the dump car to drive the impeller, and it takes time to install the impeller, and there is no problem with the horizontal dump mechanism. Was not considered. Moreover, the technique described in the above-mentioned utility model registration document 2 is to prevent the bridging of organic fertilizer by rotating two or more shafts each having a protruding wing attached to the lower part in the tank in the opposite direction. Since it is a dedicated device, it is expensive, and depending on the moisture content of the organic fertilizer, there is a risk of cross-linking on the shaft. And the technique of the above-mentioned utility model registration document 3 is to provide a feeding screw and a discharging screw in the container in the opposite conveying directions, respectively, to enable a fixed amount of spraying. When a large amount of material to be sprayed is supplied to the supply screw side, there is a problem that crosslinking cannot be prevented.

  The present invention has been made in view of the above-described conventional problems, and can be mounted even on a transport vehicle with a different dump direction, can be easily mounted, is inexpensive, and is in a state of an object to be sprayed (for example, moisture). It is an object of the present invention to provide a spraying device that can easily cope with a cross-linking phenomenon caused by a change in the amount (such as some amount).

  For this reason, the spraying device of the present invention is a spraying device that is detachably attached to the dumper-equipped transport vehicle, and a plurality of screws are spaced apart and arranged in parallel at the center of the spraying device body, The plurality of screws are each formed in a screw shape in the opposite conveyance direction, and the objects to be collected assembled by the inclination of the dumping function are mounted on the objects to be dispersed by turning the plurality of screws in the same direction. The first feature is that the sprayed material is always sprayed in a fixed amount while stirring in the reverse movement direction.

  The second feature is that the plurality of screws are at least three screws.

  According to the spraying apparatus which concerns on this invention, it has the outstanding effect that a to-be-scattered object can be sprayed by fixed quantity with the transport vehicle with a dump function.

  In addition, since a plurality of fules formed in screw shapes with different conveying directions are spaced apart and arranged in parallel and rotated in the same direction, it is possible to agitate even objects to be sprayed with different moisture contents. It has the effect that it can be sprayed without crosslinking.

It is a perspective view which shows the spreading | diffusion apparatus of this invention. It is a perspective view which shows the state which uses the spreading | diffusion apparatus of a device.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings, but it goes without saying that the present invention is not limited to this embodiment. FIG. 1 is a perspective view showing a spraying device according to the present invention, and FIG. 2 is a perspective view showing a state in which the spraying device according to the present invention is used.

  FIG. 1 is a perspective view showing a spraying device 1 according to the present invention, and three screws 2 are attached to a central portion in parallel at a predetermined interval. Each screw 2 is formed in a screw shape in the opposite conveyance direction, and can be rotated in the same direction by a driving device (not shown).

  FIG. 2 shows a state in which a non-sprayed material is loaded on a dump vehicle 3 on which the spraying device 1 is mounted. As shown in the figure, the object 5 is loaded on the packing box 4 of the dump vehicle 3, and the container 5 is dumped backward by driving a hydraulic cylinder (not shown) so that the object 5 is Move backwards. And the spreading | diffusion apparatus 1 with which the rear end of the packing box 4 of the dump vehicle 3 was driven by the drive of a drive device, and the to-be-dispersed object 5 is spread | dispersed uniformly from the back of the dump vehicle 3. FIG.

  The drive device uses a drive motor or the like and is rotated by an automobile battery. The drive device is connected by a rotation transmission device such as a gear or a chain provided at each end of the three screws 2. Rotates in the same direction and the screw 2 rotates in the same direction. By rotating the screw 2, the loaded objects 5 are always sprayed from between the screws 2 while being stirred in the reverse movement direction, so that it can be uniformly sprayed.

  The spraying device 1 of the present invention configured as described above is mounted on the discharge side of the cargo box 4 of the dump vehicle 3 at a right angle to the dump direction, and the sprayed object 5 is uniformly sprayed without cross-linking in the vicinity of the screw 2. Can be performed. In addition, since the structure of the spraying device 1 is simple and can be mounted on any dump vehicle, it is very inexpensive unlike a dedicated device.

  As described above, according to the spraying device according to the present invention, the object to be sprayed can be sprayed quantitatively by being detachably mounted at right angles to the dumping direction of the transport vehicle with a dumping function. In addition, it is possible to perform uniform spraying without causing cross-linking of the object to be sprinkled by the swinging of the plurality of screws having different transport directions.

  The spraying device according to the present invention is not only widely used in the fields of agriculture, livestock industry and road maintenance, but can also be used as equipment for maintenance of parks and public facilities.
