Agricultural uniform sowing device

Abstract

The invention discloses an agricultural uniform sowing device, which comprises a mounting plate. A barrel penetrates through the left end of the mounting plate. A No.1 piston block and a No.2 piston block are slidingly arranged inside the barrel. The No.1 piston block and the No.2 piston block are fixedly connected through a drive spring, which has the effect of buffering the downforce to help prolong service life of the device. A drive screw is vertically arranged at the middle position of the lower end of the No.2 piston block. The lower end of the drive screw penetrates through a nut block,which cooperates with the drive screw. A rolling bearing is arranged at the outer side of the nut block. Two ends of the rolling bearing are fixedly connected with the internal wall of the barrel through a locating rod. The device has a simple and reasonable structure, requires no electric drive, is used to effectively realize uniform sowing of seeds, and also can help uniformly mix seeds in a material loading chamber and a fertilizer so as to effectively enhance the sowing effect of the device, and has strong practicality.

Description

technical field [0001] The invention relates to the technical field of agricultural sowing equipment, in particular to an agricultural uniform sowing device. Background technique [0002] In modern agriculture, in many mountainous areas where the economic development is not good, farmers basically use manual sowing, and very few use seeding machines for sowing, and seeding machines are not easy to popularize due to their high cost. It is also often difficult to bear. [0003] The application number is "201420160979.4", and the patent title is "A Air Suction Precision Seed Meter". In this patent, the vacuum suction chamber is connected to the fan through a hose, so when the seed meter needs to work, it needs an external fan. Fans need to be powered or energy can be used, which not only makes the structure complex and cumbersome, but also increases the cost of energy when planting seeds, which is not easy to popularize in poor areas, so it is necessary to provide a simple and...
