Problems solved by technology

[0009] However, the sowing speed of the sowing device of the above-mentioned Patent Document 1 is about 0.6 m / s or less, and if it operates at high speed, it is easy to cause deflection on the belt, so it is not suitable for high-speed operation.
[0010] As for the current seeders, foreign ones are large and heavy, so workability is poor and the price is high, while domestic ones have the problem that it is difficult to ensure the accuracy and speed of seeding at the same time.
In addition, there are many types of feed crops such as corn, soybeans, sorghum, rice, and wheat. It is necessary to prepare multiple seeders according to the size and shape of the seeds of each crop and the sowing conditions (single seed sowing or hole sowing), which becomes an operating cost. Reasons for the increase

Embodiment 1

[0057] For seeds of different varieties, sizes, and shapes, a performance test was conducted to investigate the influence of the feeding speed of the seeds on the accuracy using the distribution device of the present invention. As for the feeding speed of corn, it is assumed that when mounted on a seeder, the seeding operation is carried out at a maximum speed of 2m / s per hole and one grain, and is performed at a rotation speed of 4 times / s, 8 times / s, and 12 times / s test. Regarding the variety of corn, there are four types of pellets: KD777LR (thousand-grain weight: 397g) and NS129SR (thousand-grain weight: 226g); flat grains: KD772スーパーLF (thousand-grain weight: 326g) and KD670SF (thousand-grain weight: 263g).

[0058] The index of precision is 1 grain rate. In addition, the assumption speed of the above-mentioned seeding work is set to be equal to the commercially available air pressurized seeder for single seed sowing. The test results are shown in Table 1.

[0059] [Tab...

Embodiment 2

[0064] In the same manner as in Example 1, a performance test was performed on sorghum to investigate the influence of delivery speed on accuracy. As for the delivery speed, it is assumed that the sowing operation of 1 seed per hole is carried out at a maximum speed of 2 m / s when mounted on a seeder, and tests are performed at rotation speeds of 8 times / s, 16 times / s, and 24 times / s. The variety of sorghum is スーパーシュガー (thousand-grain weight 32g).

[0065] The index of precision is the same as the corn of Example 1, which is the rate of 1 grain. The test results are shown in Table 2.

[0066] [Table 2]

[0067] .

[0068] In Table 2, the rate of 1 grain, the rate of lost holes, and the rate of 2 grains are the average values ​​of three consecutive 200 times of sending out respectively. As in Example 1, a high-speed camera is used to take a picture of the place where the seeds fall, and then use a monitor to Give feedback and it counts. The symbols of the distribution plate...

Embodiment 3

[0071] In the same manner as in Example 1, a performance test was performed to investigate the influence of the delivery speed on the accuracy of feed paddy and wheat that were sown in holes. As for the sending speed, it is assumed that the sowing operation of one hole and multiple seeds is performed at 1.5 m / s, and the rotation speed is 4 times / s, 6 times / s, and 8 times / s. The varieties of feed rice were リーフスター (thousand-grain weight: 27g) and Nishiaoba (thousand-grain weight: 37g), and the variety of wheat was Nonglin No. 61 (thousand-grain weight: 39g).

[0072] The assumed speed of the above-mentioned sowing operation is set to be equal to or higher than that of a commercially available irrigation direct seeding machine for row sowing of rice. The index of accuracy is the average number of grains in one hole, and 50 times of continuous sending are performed once, and the average value, standard deviation and variation coefficient of the number of grains in one hole are cal...

Abstract

A distributing device for granular materials is provided, which is suitable for granular materials of various sizes and shapes, and can realize high-speed and high-precision distribution no matter one grain at a time or multiple grains at a time. There is a rotating mechanism for rotating the drive shaft, a supply side frame, a distribution plate having a holding seat on the outer peripheral portion for storing granular materials supplied to the supply side frame in a given amount, and a distribution plate on the outer peripheral portion corresponding to the position of the holding seat. A discharge plate that houses recesses for granular materials, a delivery plate that is disposed between the distribution plate and the discharge plate and has delivery holes that deliver granular materials from the distribution plate to the discharge plate are formed in the upper portion, and a discharge plate that covers the outer periphery of the discharge plate and has a The discharge-side frame, the distribution plate, and the discharge plate of the discharge outlet of the discharge port of the granular matter housed in the recess rotate in the same direction and at the same speed around the drive shaft.

Description

technical field [0001] The present invention relates to a dispensing device for granular materials, capable of distributing and discharging granular materials such as seeds, fertilizers, tablets, etc. at a high speed each time with a certain number of grains. Background technique [0002] For example, in the distribution device used in a seeder for sowing seeds at a given number of seeds at a given time at a time, there are vacuum or pressurized air utilization based on fans and blowers, by means of grooved rollers and with The rotation of the orifice plate distributes the seeds in a roller type or an inclined orifice plate type, etc. [0003] In the past, when picking up and sowing large seeds such as corn one by one at a high speed, a vacuum type or a pressurized type for one-seed sowing was used to sow smaller seeds such as rice and wheat on multiple grains. For more seeds, use a roller type or a perforated plate type that accommodates many seeds in a certain volume. ...
