Description

[Detailed Description of the Invention] (Industrial field of application) This invention automatically forms fertilizer application grooves with multiple lines, drops fertilizer on both sides in the fertilizer application groove, and then, with the fertilizer and soil. It is related to a multi-row rotary fertilizer applicator that covers and suppresses soil by rubbing.

(Prior Art) A conventional fertilizing method of this type is, as described in Japanese Utility Model Publication No. 53-26326, after forming fertilizing grooves with a groove cutter and applying fertilizer to both sides in the fertilizing grooves. Immediately, soil is covered on the fertilizer ditch by the soil-covered discs on both sides.

(Problems to be solved by the invention) Recently, the amount of fertilizer applied is increasing year by year.

Therefore, in the above-mentioned conventional fertilization method, since the fertilizer is located in Nijo in the state of being hardened in the soil, when sowing on the fertilizer application section or planting seedlings of the crop, at first, seeds and crops Since the distance between the fertilizer and the fertilizer is large, it is difficult for the crop to grow. On the other hand, when the root of the crop extends to the fertilization part, the fertilizer burns and the growth is impaired due to the large amount of fertilizer.

(Means for Solving Problems) In order to solve the above-mentioned problems, the present invention provides a box (14) with an appropriate number of fertilizer tanks (2) above a frame (7) connected to the rear of a tractor. ) Are arranged side by side in the left-right direction, and the gear casing (10) is attached to the central portion of the front end.

Next, the operation will be described. Put the machine in the field, put fertilizer from the tank (2) into the receiving box (14), and then start the operation of the tractor and move the machine forward, and the transmission shaft (12) from the output shaft of the tractor. , Input shaft (11),
All rotary tillers ( 4 ) pass through the gear mechanism, the main shaft (13), the transmission mechanism (22), and the tiller shaft (21) in the gear housing (10) to rotate in the arrow direction of FIG. On the other hand, the wheel (29) rotates on the ground, and from the axle (30) through the transmission mechanisms (31) and (17), the front and rear rotary shafts (15) and (1).
Since 6) rotates, the fertilizer in the front part of the receiving box (14) is fed into the rear part of the receiving box (14) while being stirred by the agitating and feeding claws of the front rotating shaft (15), and the rear rotating shaft is fed. By the scraping piece of (16), the fertilizer is splashed into the discharge trough (18), and the fertilizer is divided into the fertilizer hoses (3) and (3) from their lower ends to both sides in the groove cutter (1). To fall.

Therefore, fertilizer is applied from the fertilizer hoses (3) and (3) to both sides of the fertilizer application groove while forming the fertilization application groove having a required depth and width by scraping the topsoil to both sides with the groove cutter (1). Then, the fertilized groove portion was cultivated by a rotary tiller ( 4 ) to mix fertilizer and soil on both sides of the fertilized groove, and then the soil on both sides separated by the groove cutter (1) was scraped. The soil-covered discs (5) on both sides return the fertilizer to the fertilizer application groove, cover the soil with the soil, and compress the soil with a pressure roller (6) to perform fertilizer application.

(Effect of the Invention) The multi-row rotary fertilizer applicator of the present invention has the following remarkable effects.

(1) A gear casing is attached to the center of the frame, and a main shaft is laterally mounted on the gear casing, and the main shaft is driven from the output shaft of the tractor through the transmission shaft, the input shaft of the gear casing and the gear mechanism, and the main shaft Since power is transmitted to each cultivating shaft of each cultivator of the multi-row rotary fertilizer applicator, the rotary tillers of the multi-row rotary fertilizer applicator always rotate equally and the soil of the fertilized part is agitated to even out the multi-fertilizer application. You can do it.

(2) While applying fertilizer in two rows at appropriate intervals, the soil in the fertilized area is mixed with a rotary tiller, so the soil to be sown afterwards grows loose due to tillage, and the crop grows. In addition, the fertilizer is easy to decompose because the fertilizer has two rows and a wide area is mixed well with the soil.

(3) When seeding or planting seedlings in the upper part between the fertilizer mixing parts on both sides, even if there is a large amount of fertilizer, the fertilizer is dispersed and effectively acts on the crop over a long period of time, and the fertilizer burns and grows on the crop. Disability is prevented.

Therefore, all crops such as beets, potatoes and beans can be harvested with high yield.

(4) On the fertilizer ditch where the fertilizer and soil on both sides are mixed, the soil on the both sides initially separated by the groove cutter is returned by the soil cover discs on both sides and covered with the soil, so there is no topsoil on the fertilizer ditch. With fertilizer,
Weeds are hard to grow and fertilizer can be effectively applied.

(5) Since the operations of multi-row double-row fertilization, mixing of fertilizer and soil, covering of soil, and crushing are mechanically performed in series, the work can be performed accurately and efficiently.

(6) An appropriate number of front ends of chain cases are fitted to the main shaft, and a cultivating shaft that is transmitted from the main shaft is laterally installed at the rear part of each chain case, and a plowing knife is attached to both side protruding parts of the cultivating shaft to attach the rotary shaft. Since the cultivated body is constructed, a multi-row rotary cultivated body can be easily manufactured in a small size and is advantageous in work.

(7) The amount of tillage is small and the vehicle can be driven lightly.

(8) The structure is simple and can be easily manufactured at low cost.
