Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for opening a fertilizer bag to save labor for opening the bag when the bag containing the fertilizer is put into a hopper of a sprayer in a fertilizer application operation.

[0002]

2. Description of the Related Art Conventionally, opening a fertilizer bag of this kind involves putting the fertilizer in a fertilizer bag in a hopper of a spreader,
Open one end of the bag with a sickle or the like, lift the other end of the bag and put in fertilizer, or put a fertilizer bag on the edge of the hopper and open one end of the bag with a knife like a sickle, The other end of the opened bag is lifted and thrown. In these methods, it is dangerous to handle a knife such as a sickle, and it is necessary to open the bag or lift the bag.

[0003]

In the above-mentioned conventional opening operation of the fertilizer bag, during opening operation, the worker works in a state of being waisted, and there is a problem in the working posture for transporting the fertilizer bag. , Many workers complain of back pain. In particular, in the case of fertilization work for a vast grassland, etc., the handling amount is large, and improvement has been required. For that reason, it is possible to automate the bag opening work, but for this purpose many mechanical devices are required and it can not be used in situations such as agriculture, so development of a simple device that does not require power Was desired.

[0004] In situations where a supply device (such as a conveyor) is required, the handling operation of opening during the supply operation is improved. In the case of manual supply, if the supply can be opened during the supply process, labor can be saved, and the work operation is improved and the fertilization efficiency is improved. The present invention has been made to solve the above problems.

[0005]

In order to achieve the above object, the present invention conveys a fertilizer bag filled with fertilizer to a position where the bagded fertilizer is manually or conveyorly charged into a hopper of a spreader. A gutter that slides the fertilizer bag down is installed on the cargo frame or bed of the carrier, and at the lower end of this gutter, a convex opening blade that opens by pushing the bottom of the gutter due to the gravity of the fertilizer bag sliding down the gutter is opened. It is characterized by being provided.

[0006]

The fertilizer bag opening device of the present invention having the above-described structure carries the bag containing the fertilizer into the gutter of the opening device manually or by a conveyor and uses the gravity of the fertilizer bag sliding down the gutter to collide with the opening blade. As a result, the lower end of the fertilizer bag is opened, the fertilizer is discharged from the bag, and falls into the hopper of the spreader.
Then, lift the top of the fertilizer bag and remove the bag while discharging the fertilizer to the end. By repeating such operations, continuous operations are performed, and the fertilizer application operation is improved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. 1 to 3, reference numeral 1 denotes an opening device for opening a fertilizer bag 2, which is a bag containing fertilizer. The opening device 1 includes a gutter 3 on which the fertilizer bag 2 is slid and dropped. 4 is pivotally supported via a pivot pin 5, and the inclination angle of the gutter 3 can be adjusted by an angle adjusting arm 6 interposed between the gutter 3 and the retaining column 4. On the upper surface of the lower end of the gutter 3, a convex (mountain) -shaped opening blade 7 that opens by opening the bag of the fertilizer bag 2 that slides down the gutter 3 can be attached and detached with a fixing bolt 7a, and the angle can be adjusted. It is provided in.

The opening device 1 has its lower end facing above the hopper 8 of the fertilizer spreader arranged at a position where the fertilizer is manually or by a conveyor. Opening device 1
Is installed in a state in which a hook metal 4a provided on the retaining column 4 is hooked on a cargo frame 9 or a carrier of a truck for transporting the fertilizer bag 2.

When the fertilizer bag 2 is loaded into the unsealing device 1 by the conveyor 10, as shown in FIG. 4, the conveyor 10 is supported by the support legs 10a at the end of the conveyor.
The upper portion of the unsealing device 1 is pivotally supported via a pivot pin 5a, and an inclination angle of the gutter 3 can be adjusted by an angle adjusting arm 6a interposed between the unsealing device 1 and the frame of the conveyor 10.

Next, the operation of the opening device 1 for opening the fertilizer bag 2 configured as described above will be described. ． When the opening device 1 is installed and used on the cargo frame 9 of the carrier (Fig. 1), the hook metal fitting 4a is attached to the cargo frame 9 of the truck (carriage) carrying the fertilizer bag 2, and the carrier is used. The carried fertilizer bag 2 is manually slid into the gutter 3 of the opening device 1. Then, the fertilizer bag 2 slides down on the gutter 3 at a constant speed by its own weight, the tip side thereof is pierced by the opening blade 7, and the fertilizer bag 2 opened is discharged into the hopper 8 of the fertilizer spreader and supplied. Then, the worker has the rear end of the fertilizer bag 2 to discharge the fertilizer in the front part and remove the empty bag. By repeating such operations, a predetermined amount of fertilizer is supplied into the hopper 8 of the fertilizer spreader, and the fertilizer spreader performs the spraying operation.

[0011]. When the unsealing device 1 is attached to the tip of the conveyor 10 (FIG. 4) In this case, the work is performed by a group of two workers. One person carries the fertilizer bag 2 accumulated in the fertilizer storage etc. to the conveyor 10 for supplying the fertilizer spreader, lifts it up to the hopper 8 of the fertilizer spreader, and opens it with the opening device 1 attached to the tip of the conveyor 10. . Another person removes the bag and discharges the fertilizer, and puts the empty bag together.

The angle of the fertilizer bag 2 is adjusted by the angle adjusting arm 6a so as to slide down on the gutter 3 at a constant speed (5 m / sec or more). Thereby, the sliding speed on the gutter 3 can be changed depending on the material and contents of the fertilizer bag 2. The angle of the opening blade 7 is also adjusted by the fixing bolt 7a so that the opening blade 7 appropriately pierces the fertilizer bag 2.

The opening blade 7 has an inverted V shape and has a bag width of about 80.
% Is sufficient, and it is important that the tip of the inverted V-shape is sharp. In this case, since the bag is pierced below the fertilizer bag 2, the bag is dropped by the fertilizer in a stretched state so that it can be easily pierced and opened. Therefore, gutter 3
By opening the fertilizer bag 2 in, it can be opened instantly.

As described above, by using the unsealing device 1 of the present invention, the fertilizer bag 2 is directly supplied from the carrier 9 of the carrier or the fertilizer bag 2 accumulated on the floor is supplied to the spreader by the conveyor 10. In this case, the fertilizer bag 2 can be instantly opened and supplied to the hopper 8 of the fertilizer spreader. Further, the unsealing device 1 of the present invention can be made lightweight without using power, and can be manufactured at low cost because of its simple structure.

[0015]

As described above, the device for opening a fertilizer bag of the present invention has the following effects. ． Just by pouring the fertilizer bag into the gutter, the gravity of the fertilizer bag sliding down the gutter allows the lower part of the bag to be pushed open with a convex opening blade, and the process for opening is greatly omitted. ． The work of supplying fertilizer to the hopper of the fertilizer sprayer is streamlined, and the fertilizer spraying work is streamlined. ． The work posture for supplying fertilizer to the hopper of the fertilizer spreader is improved, and the work intensity is reduced. ． The fertilizer bag is opened without power and does not require complicated mechanical devices. ． Since the opening position of the fertilizer bag is in the center position at the bottom of the bag,
The remaining amount after fertilizer discharge is small.
