Description

  The present invention relates to a spreader for a load that spreads a load such as compost mounted on the vehicle while the vehicle is running.

The amount of domestic animal excrement generated in Japan is about 90 million tons per year, and it is important to promote the use such as appropriate treatment, processing into compost, etc., and effectively returning to farmland. is there.
However, in the current situation in the livestock industry, not all are being used effectively, and improper treatments such as padding, unearthing and drifting are being carried out, and environmental problems such as water pollution and odor In addition, water pollution caused by nitrate nitrogen and Cryptosporidium (protozoa) may affect human health problems. For this reason, it is necessary to quickly resolve such a situation.
Farmers, on the other hand, endeavor to sell agricultural products that meet consumer demands. In order to produce safe, good-tasting agricultural products without the use of chemical agents, natural compost such as livestock compost can be used. Organic compost that can effectively use resources is attracting more and more attention. In this compost, crop harvesting scraps, trash, wood scraps, garbage, etc. are also effectively used, which also helps to recycle waste. However, farmers are becoming labor shortaged and aging, and the current situation is that they must rely on machines to process and spread compost.

As a means of efficiently spreading a large amount of compost etc. over a large area of land in a short time, a load spreading car that spreads the load of compost mounted on the car while driving the car is used, Compost and the like were difficult to spread and difficult to spread evenly. Usually, since the load is loaded by a loading machine such as a tire excavator, the center part is generally raised from the left and right ends in the direction orthogonal to the traveling direction of the spreading car. However, the amount of spraying in the center portion is larger than that in the left and right ends, and there is a disadvantage that uniform spraying cannot be performed. The applicant of the present application has proposed a loader-dispersing vehicle for the purpose of smoothly transferring the loader to the rear and spraying the load evenly (see Patent Document 1). As a result, appropriate measures were not taken.
JP 2003-289703 A

  The present invention improves the conventional problems as described above, and moves the mounted object having a shape in which the center part is raised from the left and right end parts in the direction orthogonal to the traveling direction to move from the center part to the left and right. It is an object of the present invention to provide an on-board dispersal vehicle that enables a uniform and smooth dispersal by transporting an object rearward so as to have a uniform height horizontally.

  The present invention achieves such an object, and the invention according to claim 1 is such that the bottom part of the loading platform has a shape in which the center part rises from the left and right end parts in the direction orthogonal to the traveling direction. A roller belt for transferring objects toward the rear is arranged, and a spiral in the opposite direction from the center to the left and right ends in the direction orthogonal to the traveling direction is provided above the vicinity of the rear end of the roller belt. This is a loader spreading vehicle characterized in that one beater is arranged, a second beater for spreading and spreading the load is arranged at the end, and an openable / closable rear gate is arranged.

  According to the loader dispersal vehicle of the present invention, it is possible to evenly transfer a load having an uneven height in a shape in which the center portion is raised from the left and right end portions in a direction orthogonal to the traveling direction. In addition, uniform and smooth spraying is possible, and it is particularly useful as an agricultural spreader for compost etc. It is also useful as a disperser for freeze-removal agents and other various dispersers.

Hereinafter, the present invention will be described in detail according to the illustrated embodiments.
In FIG. 1, reference numeral 1 denotes a loader spreading vehicle according to the present invention, and the loader spreading vehicle 1 includes a loading platform 2 including a first roller belt 3, a first beater 5, a second beater 6, and a rear gate 7. The second roller belt 4 can be arranged after the first roller belt 3, and FIG. 1 shows an embodiment thereof. When the second roller belt 4 is not used, as shown in FIG. 12, the second beater 6 is disposed after the first beater 5, and the mounted object accumulated after the first beater 5 is the second beater. 6 can be sprayed.

  The first roller belt 3 is an endless belt that is driven by the rollers 31 and is arranged on the bottom of the loading platform 2 to transfer a load such as compost rearward. The lower surface of the first roller belt 3 is provided with a large number of rollers 32 at intervals in order to reduce the transfer resistance of the belt on which the load is mounted, so that the load can be smoothly transferred. It is.

  The first roller belt 3 is driven by using the power from the engine of the car. However, as shown in FIG. 1, the power transmission to the first roller belt 3 is performed by, for example, driving the engine with a power take-off (PTO). ) 10, drive shaft 11, pulley 12 (with a v-belt), power transmission shaft 13, etc., are transmitted to the gear box 14, and from here, as shown in FIGS. 2 to 4, the sprocket 15, the clutch 16, and the speed reducer 17. Then, the first roller belt 3 is driven by being transmitted to the driving roller 31 of the first roller belt 3.

  The transfer speed of the first roller belt 3 is one of the adjustment elements for making the amount of the spread material uniform, but it is important that the transfer speed is higher than the transfer speed of the second roller belt 4 described later. For example, the speed can be set to about three times the maximum speed of the second roller belt 4. Since the transfer amount of the load by the first roller belt 3 varies depending on the change in the load amount per unit area of the load of the first roller belt 3, it is held in a state larger than the actual spraying amount, and finally The appropriate spray amount is further determined by the transport amount of the rear second roller belt 4.

  Since the speed of the first roller belt 3 is higher than that of the second roller belt 4 here, a large amount of load is stored at the rear end portion of the first roller belt 3. Therefore, by measuring the degree of the load of the load on the first beater 5 described later disposed in the vicinity of the rear end portion of the first roller belt 3, the load transferred excessively exists. In this case, the transfer of the first roller belt 3 is stopped when the predetermined load to the first beater 5 is detected, and the transfer of the first roller belt 3 is started when the predetermined load to the first beater 5 is not detected. can do. At this time, it is also possible to vary the transfer speed of the first roller belt 3 by detecting or not detecting the load on the first beater 5.

  The first beater 5 is for agitating the load (including the effect of crushing the load) so that the load can be easily transferred to the second roller belt 4 from the state in which the load is stored. Smooth transfer is possible by reducing the occurrence of bridging of objects. The driving force of the first beater 5 is transmitted from the gear box 14 directly or through an appropriate sprocket 50 through the chain 18 as shown in FIG. 4, and on the slack side of the chain 18, FIGS. As shown in FIG. 2, a tensioner 19 and a limit switch 20 having a weak tension force are provided to remove the dandruff of the chain 18 to prevent the chain 18 from coming off and to detect the amount of stored material.

  When the load on the first beater 5 is less than a predetermined load, the force of the tensioner 19 exceeds the driving force of the chain 18, and the idler sprocket 191 and the chain 18 are in the state of the solid lines in FIGS. The first beater 5 rotates. At this time, the limit switch 20 is on and the clutch 16 of the driving portion of the first roller belt 3 is connected, and the first roller belt 3 transfers the load to the rear. continue.

  When the load is transferred to a predetermined amount or more and the load of the load is applied to the first beater 5, the driving force of the chain 18 surpasses the tensioner 19, and the idler sprocket 191 and the chain 18 are shown by dotted lines in FIGS. (The first beater 5 is still rotating at this time), the limit switch 20 is turned off, the clutch 16 is disconnected, no power is transmitted, and the first roller belt 3 moves. Stops and overflow is avoided. A predetermined amount can be transferred to the second roller belt 4 by repeating the running and stopping of the first roller belt 3, and this mechanism enables more uniform and smooth spraying.

  As shown in FIG. 7, the shape of the first beater 5 is a reverse spiral shape of a right spiral and a left spiral with the central portion as a boundary, and a mounted object in which the central portion rises from the left and right end portions. It has an important function of moving the object to be scattered from the center part to the left and right so as to have an even height horizontally. In general, since the load is loaded by a loading machine such as a tire excavator, the center portion is generally raised from the left and right ends, so it is important to cope with this tendency. .

  The second roller belt 4 is used for transferring the load transferred to the rear end of the first roller belt 3 to the rear gate 7, and the load transferred by the first roller belt 3 is used as a bridge. It is desirable to transfer smoothly without causing it. Therefore, the second roller belt 4 can be traveled so as to be changeable to a desired speed, and it is possible to prevent the bridge of the load due to traveling at a constant speed.

  The second roller belt 4 is also driven using the power from the engine of the car, but the power transmission to the second roller belt 4 is the same as in the case of the first roller belt 3 up to the gear box 14, As shown in FIGS. 8 to 10, the second roller belt 4 is driven by being transmitted to the driving roller 41 of the second roller belt 4 through the clutch 21, the transmission 22 and the speed reducer 23.

  The spray amount is adjusted by changing the speed of the second roller belt 4 with the transmission 22. This transmission 22 is performed by changing the diameter from the center of the portion in contact with the belt by widening or narrowing the space between the inner vehicle and the outer vehicle, and moving the belt fitted therein to the inside and outside. Is. In order to command this speed change operation in the vehicle, a speed change switch is installed in the driver's seat, while a sprocket 25 is attached to the transmission 22 and the power package is turned on in response to the change switch command to rotate the sprocket 25. The hydraulic pressure is generated by moving the hydraulic cylinder 26, the arm 27 shown in FIG. 9 is moved, and transmitted to the speed increaser 28, the sprocket 29, the chain 30, and the sprocket 25 to change the speed. A push-pull wire 33 is provided on one side of the arm 27 so that the movement of the arm 27 can be confirmed on the operation panel in the driver's seat. Since this operation can be performed easily and smoothly with only one switch on the operation panel, it is not dangerous, requires no labor, and can be operated by anyone.

  In addition, since the 2nd roller belt 4 can change a speed as mentioned above, it can transfer a load smoothly without a bridge | bridging producing. Although the first beater 5 reduces the occurrence of bridges on the load, it cannot be completely eliminated, but it can be completely eliminated by changing the speed of the second roller belt 4.

  The second beater 6 is for diffusing the load transferred by the second roller belt 4 so that it can be easily sprayed, thereby enabling smooth spraying. The second beater 6 can be driven by transmission of power from the sprocket 51, as shown in FIG.

  The rear gate 7 is arranged at the rearmost opening of the loading platform 2 so that it can be opened and closed by the operation of an open / close cylinder or the like. The rear gate 7 is opened when spraying the load, and when spraying ends. It is designed to be closed. Since this operation can be performed with one of the operation panels on the driver's seat, the workability is very good.

  All the operations described above can be performed in the driver's seat. Here, the operation panel 34 provided in the driver's seat shown in FIG. 11 will be described. When an on / off switch 35 is provided, and when spraying is temporarily stopped to make a U-turn, the electromagnetic clutch for driving both roller belts is turned off by turning off the switch 35 so that the roller belt Stop the movement, stop spraying (the first and second beaters are spinning but not spraying), and when the U-turn is over, turn on again and move both roller belts to spray. Next, an open / close switch 36 for the rear gate 7 is provided and can be operated at the driver's seat. The open / close cylinder of the rear gate 7 can be provided with an open / close auto switch, and a lamp 37 operated by this switch can be provided on the operation panel 34 of the driver's seat and displayed. Can be confirmed in the driver's seat, it is easy to work and safe. In addition, an auto switch is further provided in the middle of the open / close cylinder, and a lamp 37 that is actuated thereby is provided on the operation panel 34, so that the auto switch can be moved to a predetermined gate open position, so that it does not fly. Can be. Further, as described above, the switch 38 for changing the speed of the second roller belt 4 is provided so that the speed can be changed. A display pointer 39 is provided so that the movement of the arm 26 indicating the shift state can be confirmed on the operation panel 34 in the driver's seat by the push-pull wire 33. In this way, all operations can be performed at the driver's seat.

  As described above, the mounted spreader of the present invention is particularly useful as an agricultural spreader for compost, granular fertilizer, etc., but the first beater 5 and the second beater 6 are removed, and as necessary. By extending the second roller belt 4 to the rear, it is possible to apply sand, gravel, etc. as a ground for road pavement such as asphalt, road freezing remover, etc. or other various types of spraying. . Further, it is possible to use the nail of the second beater 6 for turning compost back. The second beater 6 can be provided with a claw to further improve the pulverization effect.
