Description

[Detailed description of the invention] In this case, a mounting bracket 3 for attaching the tractor tilling rotary 2 to the rear part is provided on the upper part of the machine frame 1, compaction rollers 4, 4 are provided on the lower part, and a seeding tank support frame 5 is used for rotating the seeding valve. A ratchet wheel 6 is provided, a sowing valve 7 and a sowing hose 8 are supported on the same frame 5, and a downward pin 9 provided on the same frame 5 is removably fitted into a pin hole 10 provided on the machine frame 1. The machine frame 1 and the seeding tank support frame 5 are formed so as to be separable, and the pin hole 11 of the downward pin 9
The present invention relates to a seeding machine in which the support frame 5 and the hitch 14 of the tailor 13 are detachably formed by a connecting fitting 12 having the following. One set of compaction rollers 4, 4 is provided on both sides of the machine frame 1, and short pipes 15, 15 that can be freely adjusted up and down are provided in the center thereof, and the mounting bracket 3 is provided with a forward U-shaped bracket 16 on the short pipes 15, 15. This is fitted into the hitch 17 of the tilling rotary 2, and the hitch 17 and the metal fitting 3 are connected by the pin 18.
Formed to connect with. The compacting rollers 4, 4 connect a downward arm 19 provided on the machine frame 1 and a mounting arm 21 of a roller shaft 20 with a connecting rod 22, and press the ground with the force of a spring 23. A seeding tank 2 is placed on the upper surface of the support frame 5.
4 and fertilizer tank 25, both tanks 2
A rotary seeding valve and a fertilizing valve 7, 26 are provided at the lower part of the rotary valves 4, 25, respectively, and hoses 8, 27 are provided at the lower part thereof, respectively, and open toward the ground. Pin holes 10 and 11 are upright short pipes 28 and 29
formed by. As shown in FIGS. 2 and 3, the connecting fitting 12 consists of the above-mentioned upright short pipe 29 provided at the rear of the backward U-shaped fitting 30 and the upright short pipe 31 provided at the front. 31 is inserted into the backward U-shaped hit 14 and connected with a pin 32. The tailor 13 has a pair of rolling wheels 33, 33 supported on the machine frame, and consists of a driving motor 34 provided on the machine frame and a walking handle 35 extending rearward, and a hitch 14 is provided at the rear end of the machine frame. , the same hitchi 1
Various working machines are attached to 4, and rolling wheels 33,
33 can be replaced with a tire wheel. 36 in the diagram
39 is the chain case, and 40 is the chain that is wound around the axle 37 and intermediate shaft 38 of the ratchet wheel 6.
42 is a chain that is wrapped around the intermediate shaft 38 and the rotating shaft 41 of the rotary valve (seeding valve) 7, 42 is a chain that is wrapped around the rotating shafts 41 and 43 of both valves 7 and 26
44 is a spring for lowering the ratchet wheel provided between the chain case 39 and the support frame 5, and 45 is a support rod for the ratchet wheel 44.

Therefore, as shown in FIG. 1, the support frame 5 and the machine frame 1 are connected by the downward pins 9 and the pin holes 10 mutually fitting, and the mounting bracket 3 of the machine frame 1 is connected to the tractor tiller rotary 2. By attaching it to the rear, plowing and seeding can be done at the same time using a tractor. In addition, in the corner of the fishing field or in a fishing field where it is difficult to use a tractor, the fitting between the downward pin 9 and the pin hole 10 is separated, the support frame 5 is removed from the machine frame 1, and this is connected to the hitch 14 of the tailor 13 with the connecting fitting. 12, the handle 35 is held, and the tailor 13 only performs seeding work.

Conventionally, the seeding machine attached to the rear of the tractor tilling rotary is used exclusively for tractors, so sowing by a Taylor is carried out in the corners of the field and other areas where tractors cannot be used. It was necessary to prepare various types.

Since the present invention is constructed as described above, it is possible not only to combine the machine frame 1 and the support frame 5 and easily use it in the tractor tillage rotary 2 to perform plowing and sowing operations at the same time, but also to be able to carry out plowing and sowing operations at the same time. Separate the frame 5 and connect it to the tailor 13.
The seeding work according to No. 3 can be easily performed, and there is no need to prepare two types of dedicated machines, and the seeding work can be simplified.
