Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tank fixing device for a slurry injector that facilitates storage and removal of a suction hose.

Conventional slurry tanks in slurry injectors are often made of iron plates, and a suction hose receiving fitting is welded to the outer circumferential surface of the slurry tank, or a hose receiving fitting is attached to the side of the machine frame on which the tank is mounted.

However, in the case of a so-called direct-mounted slurry injector that is connected to a tractor so that it can be raised and lowered via a three-point linkage mechanism, it is necessary to reduce the weight of the work equipment as much as possible, and it is desirable that the slurry tank be made of lightweight resin. However, integrally forming a protrusion such as a hose receiving hook on a resin tank has the disadvantage of being too costly due to the mold, and if the receiving fitting is attached to the aircraft frame side, the suction hose The storage will be wrapped around the lower side of the tank, and when removing the hose when suctioning slurry, it will be necessary to go around the tank one by one to remove it, or to remove it by pulling up several wraps from the bottom of the tank to the top. It was an incredible inconvenience.

The present invention is an attempt to improve the above-mentioned drawbacks, and the slurry tank is tied and fixed onto the fuselage frame by a tank fixing band that is stretched from the top surface of the tank to the sides of the tank on both sides of the fuselage frame. The tank fixing band is characterized in that a suction hose receiving fitting is integrally attached to a portion of the band along the side surface of the tank and located closer to the top surface of the tank.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, FIGS. 1, 2, and 3 are a front view, a rear view, and a side view of a slurry injector A, and 1 is a body frame; 2 is a synthetic resin slurry tank mounted on the fuselage frame 1, and a three-point link mounting frame 3 is mounted on the front of the fuselage frame 1.
However, mounting frames 5 for the tail wheel 4 are integrally built into the rear part, and these front and rear mounting frames 3 and 5 are used to restrict displacement of the tank 2 in the longitudinal direction and to prevent the tank 2 from shifting in the lateral direction. The displacement can be prevented by left and right side stoppers S. 6 is a slurry injection nozzle, 7 is a coulter, and slurry injector A (not shown) is connected to the rear of tractor B in FIG. A connected pump 8 injects the slurry in the tank 2 into the soil through a nozzle 6 and fertilizes the soil.

9 is a suction hose with a strainer 9a attached to its tip, 10 is a strainer receiver, and 11 is a stand.

12 is a band for fixing the tank, and this band 1
2 is hung in the longitudinal direction of the fuselage frame 1 from the side to the top of the tank 2, and its rear end is locked to the tail wheel mounting frame 5 via a hook 13, and its front end is secured to a bolt 14 and a nut 15. It is connected and fixed to the three-point link mounting frame 3 via.

Reference numeral 16 denotes a receiving fitting for the suction hose 9. As shown in FIG. It is installed integrally.

Figures 6 and 7 show the mounting structure of the tail wheel 4, and the vertical adjustment of the tail wheel 4 is made at the pivot point P of the hawk 4a.
Lift up the U-shaped planar handle 4b fixed nearby with one hand, remove the pin 4c, and align the pin hole 4'd of the adjustment part 4d with the pin hole 4'e of the bracket 4e fixed to the tail wheel mounting frame 5. and insert pin 4c. At this time, the tail wheel 4 and the hawk 4a are in a state where they can freely rotate relative to the adjustment part 4d, but since they are lifted by the handle 4b, they can be lifted and adjusted easily without being unnecessarily rotated from side to side. Furthermore, since the handle 4b is located near the rotation fulcrum P, it also functions as a rotation stopper that prevents the handle 4b from rotating beyond a predetermined angle α during work (see Figure 7). .

FIG. 8 is a detailed view showing the state in which the pump 8 is attached to the tractor B. The pump 8 is connected to a drawbar C installed in the transmission case b of the tractor B via a bracket d and a pin e. , the pump drive shaft 8a is fitted onto the PTO shaft a so that power is transmitted thereto. The pump bracket d is used to prevent the pump 8 from rotating and coming off when the PTO shaft a is rotated, but when the pump 8 is removed from the tractor B, the pump bracket d
As shown in the figure, by storing the pump 8 by suspending it using the pump bracket d from the end hook 18' of the cheese bracket 18 attached to the front part of the fuselage frame 1, the pump body and hose can be prevented from getting in the way. It is designed to prevent damage from being hit.

In the above-mentioned configuration, when urine is sucked into the tank 2 from a cowshed urine collection etc., a receiving metal fitting 16, which is integrally attached to the tank fixing band 12 and provided on the upper side of the tank 2, is used. 16, the suction hose 9 is wound around the upper outer circumference of the tank 2.
Remove the wrapped bundle from above the tank, stretch it, and insert the tip strainer 9a into the urine reservoir T as shown by the phantom line in FIG. In this state, the pump 8 is operated to transfer urine into the tank 2. When the suction work is completed, the suction hose 9 is placed in the receiving fitting 16 as shown in the figure and wound around the outer circumference of the tank.

As described above, the present invention securely fixes the slurry tank onto the fuselage frame by means of a tank fixing band that extends from the top surface of the tank to the sides along both sides of the fuselage frame. Since the suction hose holder is integrally attached to the part of the band along the side of the tank and located near the top of the tank, it is possible to install a hose holder integrally with the slurry tank, or attach a hose holder to the aircraft frame side. It has a simpler structure and is less expensive than the one that is attached to the tank, and the suction hose can be wrapped around the top of the tank via the receiving metal fitting near the top of the tank, so when removing the hose, it is easy to wrap it around. The bundle of hoses can be easily removed from above the tank, and the hoses can be stored just as easily.
