Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fertilizer-seeding device that directly sows fertilizer in a dry field.

[0002]

[Prior art]

 Conventionally, a technique related to a dry-field direct-seeding device for paddy rice, wheat, etc. is known. In this type of dry-field direct sowing, a fertilizer applicator is placed on the front of the rotary tiller attached to the tractor to disperse fertilizer, and a seeder is placed at the rear of the rotary tiller to cultivate and fertilize the fertilizer. The seeds were sowed after stirring. The fertilizer sowing machine was driven by a motor that supplied electric power from a battery.

[0003]

[Problems to be solved by the device]

 If the motor is used to drive the feeding device of the fertilizer sowing machine as described above, fertilizer and seeds are fed at a constant speed regardless of the traveling speed of the tractor, so load is applied to the tractor, and when starting work. If there is a change in the speed of the fertilizer, the amount of fertilizer applied and the amount of seeding will change, resulting in poor accuracy. It is also difficult to adjust the feeding speed, and it would be costly to detect and control the speed with a sensor. Moreover, the fertilizer feeding device and the seed feeding device were driven simultaneously by the motor.However, since each feeding shaft used a single shaft, the seeding device closed the shutter by closing the shutter of the feeding device for each row. However, in the case of the fertilizer application, the fertilizer tanks consist of several fertilizer tanks, so it is not possible to stop the fertilizer, and the fertilizer is overloaded at the end of the field, resulting in excessive fertilizer and adversely affecting growth. There was.

[Means for solving the problem]

 The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, the fertilizer applicators are independently arranged in parallel, the seeding device is placed in the rear part of the fertilizer application device, the seed feeding device is driven by the compression roller, the feeding shaft of the seed feeding device is extended to both sides, and the seed feeding device is extended. Power is transmitted from the shaft to the input shafts of the left and right fertilizer applicators, and power transmission on / off means are arranged on the left and right input shaft portions, respectively.

[0005]

[Action]

 Next, the operation will be described. In the present invention, the rotation of the compression roller rotates the feeding shaft 30 of the seeding device through a sprocket, a chain, etc. to feed a certain amount of seeds, and the seedling is fed from both sides of the feeding shaft 30 via a sprocket, a chain, etc. The input shaft of the fertilizer application device is rotated, and the left and right fertilizer feeding shafts 35L and 35R are driven through the power transmission on / off means A to feed the fertilizer and input the power transmission on the unworked side at the field end. -The cutting means A is cut so that fertilization and seeding can be performed uniformly.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. That is, since the sowing device and the fertilizer applying device are configured to be driven by the compression roller, the work can be performed at the speed of the traction device, and the right and left means for turning on / off the power can be provided from both sides of the payout shaft of the seed paying device. Since the fertilizer feeding device is configured to be driven via the fertilizer feeding device, the fertilizing work can be performed on only one side by operating the power input / turn means, and the fertilizing feeding device on the left and right sides of the feeding shaft of the seed feeding device can be operated. Since it is driven, the power transmission structure is simple, and it is only necessary to arrange the power on / off means in two places.
