Description

TECHNICAL FIELD

[0001] The utility model belongs to rice fertilization technical field especially, relate to a kind of rice side deep fertilizer distributor. BACKGROUND

[0002] In the process of rice planting, fertilization is the key link to improve yield and quality, base fertilizer should be applied, before transplanting, combine with land preparation, organic fertilizer, compound fertilizer is evenly applied in field, lay a good foundation for the growth of rice, organic fertilizer can improve soil structure, enhance the ability of fertilizer and water conservation, nitrogen fertilizer is applied during tillering stage, promote rice tillering, make plant more luxuriant, improve effective ear number, pay attention to nitrogen, phosphorus, potassium cooperation during earing stage, appropriate amount of potassium fertilizer is applied, can strengthen stem, improve resistance to lodging, help ear big and grain more.

[0003] For example, the patent number CN221996032U discloses a rice side deep fertilizer distributor, which belongs to the technical field of agricultural machinery. It can adjust the fertilization depth with simple means and realize quantitative fertilization. The fertilization assembly is connected with the fertilizer box through the fertilization pipe and is fixed below the rack for quantitative fertilization. The depth adjusting device is installed below the rack and located in front of the fertilization assembly for adjusting the ditching depth of the ditcher. The ditcher is installed on the depth adjusting device. The fertilization assembly of the utility model not only can realize quantitative fertilization, but also can change the fertilization amount on the basis of quantitative fertilization according to different needs of crops, and can also realize uniform fertilization, with good fertilization effect. Compared with the existing fertilization device, it is more suitable for fertilization operation. The depth adjusting device can adjust the ditching depth of the ditcher, which can be achieved by rotating the screw handle, and the operation is simple. At the same time, the scale can realize accurate adjustment, and the cost is low.

[0004] The above-mentioned patent has the following problems:

[0005] The device has some shortcomings when in use, such as: when fertilizing, the device uses a driving motor to drive a plurality of quantitative bowls to rotate, thereby indirectly achieving continuous discharging effect. However, the time required for ditching by personnel is different, which may result in discharging before the ditch is properly opened, thereby causing waste of fertilizer. If the driving motor is repeatedly turned on and off, the work efficiency will be reduced. Moreover, the driving motor needs to be charged for a long time in the rice field, which is inconvenient. Therefore, we propose a rice side deep fertilizer distributor. UTILITY MODEL CONTENTS
