Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side-discharging type agricultural fertilizer spraying device that is pulled by a tractor or the like and sprays fertilizer from the side.

[0002]

[Prior art]

 Conventionally, there is known a spraying device in which a fertilizer-holding and movable tank, a sprayer provided outside the tank, and a single auger for transporting the fertilizer to the sprayer are provided near the bottom of the tank. .

[0003]

[Problems to be solved by the device]

 However, conventional spraying equipment can spray fertilizers with low stickiness such as high-moisture compost, but when fertilizer 5 such as hard and sticky compost or sludge is added, as shown in Fig. 4, the auger at the bottom of the tank Only the four parts of the fertilizer 5a were discharged, and the fertilizer above the auger remained without falling, and the fertilizer formed a bridge. An object of the present invention is to provide an agricultural fertilizer spraying device capable of preventing the fertilizer from forming a bridge and uniformly spraying the fertilizer.

[0004]

[Means for Solving the Problems]

 A configuration of the present invention for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. The present invention has a movable tank 11 having a substantially V-shaped cross section, which stores fertilizer and has a fertilizer discharge port on a front side wall, and a tank provided near the bottom of the tank 11 so as to be horizontally rotatable in the moving direction of the tank 11. A first auger 14 for crushing the fertilizer in 11 and transporting it to the front part of the tank 11, and a sprayer 12 provided at the fertilizer discharge port for spraying the fertilizer transported by the first auger 14 to the side of the tank 11. It is an improvement of an agricultural fertilizer spraying device provided with a drive means 13 for rotationally driving the first auger 14.

A characteristic configuration thereof is that a second auger 16 that rotates in conjunction with the first auger 14 is provided above the first auger 14 in parallel with the first auger 14.

[0006]

[Action]

 The first auger 14 rotates to convey the fertilizer in the surroundings to the front of the tank 11 while crushing the fertilizer. The second auger 16 adds fertilizer located above the first auger 14 around the first auger 14.

[0007]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, the agricultural fertilizer spraying device of the present invention stores a fertilizer and has a tank 11 having a fertilizer discharge port on a front side wall with respect to a traveling direction and a lateral side of the tank provided at the fertilizer discharge port. It comprises a sprayer 12 for spraying the fertilizer in the tank 11 and a drive means 13 for driving the auger 14.

The tank 11 is made of a steel plate and has a substantially V-shaped cross section. Flat plates are welded to both ends of the tank 11 and have an opening 11 a at the top. The bottom of the tank 11 is welded to the towing frame 11b connected to the tractor together with the reinforcing member 11e, and a fertilizer discharge port (not shown) is provided on the side wall on one side of the front portion. An axle 11c is welded to the towing frame 11b in a direction orthogonal to the frame 11b so that the tank 11 can be moved, and a pair of or a plurality of rotatable tires 11d are provided at the tip thereof. As shown in FIG. 2, a first auger 14 that is horizontally rotatable in the moving direction of the tank 11 and a second auger 16 that rotates in conjunction with the first auger 14 are provided above the first auger 14 near the bottom of the tank 11. It is installed parallel to the auger 14. As shown in FIG. 2, the inner bottom surface of the tank 11 is curved along the rotation locus of the first auger 14 and is formed with a proper gap.

The sprayer 12 provided at the fertilizer discharge port of the tank is carried in through a shutter and a fertilizer discharge port, which are provided in a cover formed so as to surround the fertilizer discharge port and which can be opened and closed, though not shown. It has a spraying mechanism for spraying the fertilizer to the side of the tank 11.

A driving means 13 for driving the auger 14 and the spreader 12 by a dynamic force obtained from a tractor (not shown) through the PTO 13a is provided at the front of the tank 11. The driving means 13 has a decelerating means or an accelerating means such as a chain, a bearing or a gear and is covered with a cover.

In the first auger 14, a spiral fin 14b is welded around a cylindrical shaft 14a. One end of the shaft 14a is rotatably supported by a bearing 14c at the rear part of the tank 11, and the other end is pivotally supported by the front part of the tank and the extension part penetrates and is connected to a driving means 13 provided at the front part of the tank. The second auger 16 has a spiral fin 16b welded in the opposite direction to the first auger 14 around a prismatic shaft 16a, and has a bearing 16c axially supported at the front of the tank and the other end at the rear of the tank. Penetrate. A sprocket 16d is provided at the other end extension of the second auger 16 and is connected to a sprocket 14d provided at one end of the first auger 14 by a chain 17. The sprockets 14d and 16d and the chain 17 are covered with an openable / closable cover 18.

The operation of the agricultural fertilizer spraying device thus configured will be described. In this agricultural fertilizer spraying device, a traction frame 11b is connected to a tractor, and a PTO 13a for sending power to a driving means 13 is connected to a power unit of the tractor. Fertilizer such as compost for spraying is carried into the tank 11 through the opening 11a in the upper portion of the tank 11. Next, the fertilizer is moved by a tractor to a position where the fertilizer is to be sprayed, and the sprayer 12 is directed to where the spraying is required. In this state, the power from the tractor is transmitted to the PTO 13a. Then, the power is converted into an appropriate rotational power by the driving means 13 to drive the sprayer 12 provided at the fertilizer discharge outlet of the tank 11 and the first auger 14 provided inside the tank 11.

The first auger 14 provided near the bottom of the tank 11 rotates and conveys the fertilizer in the surrounding area to the front of the tank 11 while crushing the fertilizer. The fertilizer transported by the first auger 14 moves from the fertilizer discharge port to the spreader 12 and is spread by the spreader 12 to the side of the tank 11. Around the first auger 14 to which the fertilizer has moved, the fertilizer in other places accumulated in the tank 11 newly invades and the fertilizer is constantly sent to the sprayer 12. In this case, the second auger 16 is rotated in the same direction as the first auger 14 by the chain 17 provided at the rear part of the tank 11, and the fertilizer located above the first auger 14 is moved to the rear of the tank 11 to remove the fertilizer. Fertilizer is added around the moved first auger 14 while crushing.

Although the tank is pulled by the tractor in this embodiment, it may be provided on the bed of the vehicle. Further, in the present embodiment, the axis of the first auger is formed in a cylindrical shape, but it may be a prismatic shape, and the axis of the second auger may be a cylindrical shape. Further, in the present invention, the second auger is interlocked with the first auger by the chain at the rear part of the tank, but this may be interlocked in the driving means provided at the front of the tank.

[0015]

[Effect of device]

 As described above, according to the present invention, since the second auger is provided above the first auger provided near the bottom of the tank, even if the fertilizer such as compost and sludge that is hard and sticky is sprayed, the second auger is used. Always crushes the fertilizer above the first auger, so the fertilizer does not form a bridge. Accordingly, the first auger can always supply the fertilizer to the fertilizer sprayer, and as a result, the fertilizer can be uniformly sprayed.
