Description

[Detailed Description of the Invention] The present invention relates to a seeding row spacing adjustment device for a direct seeding machine.

As a device related to this invention, Jikosho
As disclosed in No. 35-4430, the fertilizer buckets of a fertilizer removal machine in which a plurality of fertilizer buckets are arranged horizontally in parallel on the machine body can be freely adjusted in position in the horizontal direction so that the spacing between the fertilizing rows can be changed. The row spacing adjustment position is widely known, but since the fertilizer bucket in this device is fixed to the aircraft body with bolts, when changing the fertilization row spacing, the bolts must be unfastened and then the fertilizer can be adjusted. This requires a series of very complicated operations such as moving the bucket to the desired position and re-fastening the bolts, and the above operations can only be performed when the aircraft is stopped.
Fertilizer application work has to be interrupted each time the fertilization row spacing is changed, reducing work efficiency. Furthermore, when the fertilizer bucket is moved to the outside of the machine to widen the fertilization row spacing, incorrect steering of the machine may occur. Accidents such as this tend to occur when the fertilizer bucket comes into contact with field ridges, etc., but due to such contact accidents, the fertilizer bucket is easily damaged because it is fixed to the machine body. It had various problems.

Therefore, the present invention has been devised to solve the above-mentioned problems regarding the seeding row spacing adjustment device in a direct seeding machine.

Next, the present invention will be explained below based on the drawings. Figure 1 shows a side view of the entire direct seeding machine.
4 is installed, and both handle rods 1, 1 are extended rearward from the rear.

Seeding devices A2, A1, and A3 are respectively arranged behind the wheels 3 and 3 and on both left and right sides of the traveling body C, and each seeding device A1, A2, and A3 is supplied from the hopper 4 above. Each sowing machine A is installed so that a predetermined amount of seeds can be fed out from the falling gutter 5 at the rear by feeding out the seeds by an internal feeding roll.
1, A2, and A3 are connected to a float 7 via a support 6, and both notches 8, 8 formed on both rear sides of each float 7 have both outlets 5a, 5a at the lower end of the drop gutter 5. Grooving bodies 9, 9 are installed on the lower surface of the float in front of both notches 8, 8, and cultivating soil bodies 10, 10 are installed on the rear, respectively, and on the outside of the left and right floats 7, 7. In addition, guard rods 11, 11 are installed respectively.

The central seeding machine A2 is fixedly supported on the traveling machine body C via a mounting device (not shown), and the central seeding machine A
2 and the traveling body C are integrated, and a support rod 13 is fitted to the support stand 6 in the center sowing machine A2 and fixed with a bolt 12, and a support rod 13 is fixed to the tip of this support rod 13. Support bodies B1 and B2 consisting of support pipes 14 are horizontally extended in the lateral direction, and on the support stands 6 of the side sowing machines A1 and A3,
A support rod 16 is provided which is fitted into this and fixed with a bolt, and the support rod 16 is slidably fitted and connected within the support pipe 14 of the supports B1 and B2 to support the supports B1 and B2. A compression spring 18 is interposed between the rod 13 and the support rod 16 as a biasing means for pressing and urging the support rod 16 laterally outward. A pipe 17 serving as a guide for guiding the sliding of the support rod 16 is fixed to the tip of the support rod 16.

Further, a detent pin 20 fixed to the support 16 is fitted into a long hole 19 in the longitudinal direction formed on the circumferential surface of the support pipe 14, and a wire is inserted into a support metal 21 fixed to the upper part of the support rod 16. Connect one end of 22,
A wire 22 is inserted through a latch 23 fixed to the upper part of the support pipe 14.

A guide plate 25 is vertically provided on a support frame 24 installed across the base sides of both handle rods 1, 1, and engagement recesses 26a, 26a and 26a are provided on the upper and lower sides of the guide plate 25, respectively.
Horizontal grooves 27a and 27b having a large number of grooves 26b are formed, and the upper groove 27a is provided with the operation lever 2a that connects the other end of the wire 22 on the left support body B1, and the lower groove 27b is provided with the operation lever 2a on the right side. The support body B2 is constructed by installing an operating lever 2b that connects the other end of the wire 22, respectively.

Therefore, during work, each sowing machine A1, A2,
Seeds fed out from A3 are sown through the notches 8, 8 of the float 7 into the trenches of the rice field formed by the trenchers 9, 9, but the handle rods 1,
The operator driving on the 1st side presses the operating lever 2a,
2b from the engagement recesses 26a, 26b, and remove the groove 2.
7a, 27b to other engaging recesses 26.
When operated to engage a and 26b, respectively,
Both wires 22, 22 can be pulled or loosened, thereby causing the support rod 16 to release the compression spring 1.
8 and are pulled toward the support rod 13 side, or are pushed outward by the compression spring 18, so that the sowing machines A1 and A3 on both sides approach or move away from the central sowing machine A2. Therefore, the spacing between sowing rows can be adjusted.

In addition, the sowing devices A1 and A3 on both sides are operated by the outward pressing force of the compression spring 18 serving as the urging means and the operation lever 2.
Since the tension of the wires 22 connected to the wires a and 2b is always balanced and maintained in a state where movement inward of the machine is permitted, the sowing machines A1 on both sides may be damaged due to incorrect steering of the machine. , A3, even if it comes into contact with a field ridge, etc., the sowing device A1, A3 will immediately
It is possible to prevent the seeds from retreating into the interior of the machine and causing major damage to the seeders A1 and A3.

In this way, the present invention has a plurality of sowing devices A1, A
In a direct sowing machine in which 2 and A3 are arranged laterally side by side on a traveling body C, supports B1 and B2 are extended to one of the sowing machines A1, A2, and A3, and supports B1 and B2 are installed to extend from the other sowing machine A1, A support rod 16 is fixed to A3, and the supports B1 and B2 and the support rod 1
A biasing means 18 for biasing the support rod 16 outward is interposed between the supports B1 and B2 and the support rod 16 to slidably fit and connect them. In order to slide the other seeding devices A1, A3 against the urging means 18, the other seeding devices A1, A3 and the operating levers 2a, 2b are connected via a wire 22, and the operating lever 2a , 2b are attached to the handle rod 1 provided on the traveling body C,
Seeding devices A1, A2, by operating levers 2a, 2b.
The spacing between A3 can be adjusted and the spacing between sowing rows can be easily changed. Therefore, unlike conventional equipment, when sowing is interrupted and adjusted and then the work is resumed, there is no interruption during the work. Since it can be adjusted, work can be made extremely efficient, and even in deformed fields, seeds can be sown in accordance with the shape of the field.

Furthermore, the other seeding device A1, A3 arranged on the side
is the outward biasing force of the biasing means 18 and the operating lever 2.
Since the seeders A1 and A3 are held in a position where the tension of the wires 22 connected to the wires a and 2b are balanced, and the movement inward of the machine is allowed, the sowing machines A1 and A3 can be moved to the field by erroneous steering operation of the machine. Even if the seeders A1 and A3 came into contact with the ridges of the field, the seeders A1 and A3 would immediately retreat into the interior of the machine, and no accidents would occur that would seriously damage them. It also has the remarkable effect of allowing good seeding.
