Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a seeding machine used for agricultural work.

[Conventional technology]

Conventional negative pressure seeding machines were pulled by a tractor or the like, and did not have to be pushed manually.

[Problem that the invention attempts to solve]

Conventional negative pressure seeding machines have a power source and a vacuum pump mounted on a cultivator or the like that is pulled by a tractor, and the vacuum pump is connected to the negative pressure port and positive pressure port of the negative pressure seeding machine via two flexible tubes. It was connected. A negative pressure seeding machine was used while being towed by a tractor.

However, if it is towed by a tractor, etc., the negative pressure seeding machine cannot be used unless the person has a tractor or the like.

If you are trying to eliminate the need for a tractor or the like, you can consider moving it manually, but if you try to move it manually, the problem becomes where to place the power source and vacuum pump. For example, if a power source and a vacuum pump are mounted on a negative pressure seeding machine, the negative pressure seeding machine becomes heavy and difficult to push.

Therefore, we suspended a combination of a power source such as an engine and a vacuum pump from the human body like a brush cutter, and connected the vacuum pump and the main body of the negative pressure seeding device with a flexible pipe, without increasing the weight of the negative pressure seeding device. , the negative pressure seeding machine can be easily pushed. This invention enables the inclination angle of the hand tool to be adapted to the user's individual requirements in such a hand-pushed negative pressure seeding machine, and the negative pressure for suctioning seeds can be checked and adjusted, thereby improving the suction action. The goal is to increase efficiency.

[Means for solving problems]

This will be explained with reference to the drawings.

The base end of the paddle tool 2 is pivotally attached to a substantially horizontal vehicle frame 1 that is long in the front-rear direction, and configured to be fixed and released at any inclination angle, and an arcuate hole 4 centered on the pivot 15 is fixed to the vehicle frame 1. A bolt 6 is provided on the vertical plate 5 and protrudes outward through the circular arc hole 4 and the through hole 21 of the paddle tool 2, and can be tightened and fixed with a nut 7.
A combination 13 of a power source and a vacuum pump is fixed to a horizontal member 16 at an arbitrary point in the middle of the paddle 2, and a gas pressure gauge 8 facing the rear upper end of the paddle is fixed, and is suspended from the human body. Connected to the flow rate adjustment valve 18 via the flexible tube 17, the flow rate adjustment valve 18
By connecting the air passage 14 connecting the negative pressure seeding device main body 5 to the gas pressure gauge 8, a hand tool and an instrument of the manual negative pressure seeding device are constructed.

〔Example〕

Reference numeral 1 denotes a vehicle frame, which has a front wheel 19 and a trench digging tool 9 at the front, wheels 10 at the rear, and a negative pressure seeding device main body 11 placed in the center. Seeds in the negative pressure sowing device main body 11 are sown via a drop tube 12. 5,
5 is a vertical plate provided on both sides of the vehicle frame 1, and 15, 15 is a horizontal pivot inserted through the center of the lower part of the vertical plate fixed to the vehicle frame 1 in the vicinity of the vertical plate 5, 5. 2
is an iron double-branched lever, and the pivots 15, 15 are fitted into the pivot holes 3, 3 provided at the lower front end, and the nuts 2
It is locked at 0. 4 is a circular arc hole provided in the vertical plate 5 with the pivot 15 as the center; 6 and 6 are circular arc holes 5;
A bolt protrudes outward through a through hole 21 of the double-legged paddle 2, and by tightening a nut 7 screwed onto the bolt 6, the paddle 2 can be fixed at a desired position on the vertical plate 5. .

Reference numerals 18 and 8 denote a flow rate adjustment valve and a gas pressure gauge attached to the cross member 16 of the paddle tool, and an air passage 14 connecting the flow rate adjustment valve 18 and the negative pressure seeding device main body 11 is communicated with the gas pressure gauge 8.

A combination 13 of a power source (such as an engine) and a vacuum pump suspended from the human body is connected to a flow rate regulating valve 18 via a flexible tube 17.

[Effect]

The present invention is constructed as described above, and when the wing nut 7 is loosened and the fixation is released, the paddle tool 2 becomes rotatable about its pivot 3, and the inclination of the paddle tool 2 can be changed as desired. Then, tighten the nut 7 to fix it at any desired angle. Furthermore, since a gas pressure gauge 8 is provided, the seed adsorption and pressure can be determined using this, and the pressure can be adjusted using a flow rate adjustment valve.

[Effect of idea]

According to the present invention, the height of the hand tool is adjusted as described above to obtain the easiest handling condition of the seeding machine.
It is easy to operate, has certain benefits, and
The pressure gauge and flow regulating valve can increase the efficiency of the seeding machine operation. Further, it is extremely easy to disassemble and assemble, and is convenient for transportation and storage.
