Problems solved by technology

Due to economic reasons and terrain constraints, there are still few tractor seeders, and the most commonly used seeders are still tracted by manpower or power storage. This kind of hand seeder has a simple structure, easy to use and good economy. It is widely used in rural areas. But there are still some things that need to be improved, such as the driving wheel is usually made of steel, the weight of the planter will increase the driving resistance, and due to the need to save material and control the weight, the driving wheel with a larger diameter cannot be used. This makes the bearings at both ends of the driving wheel closer to the ridge platform, and it is very easy to get involved in sand and soil during work, resulting in a shortened service life of the bearings; since there is only one driving wheel, it will slide along the slope when planting on the ridge, resulting in a change in the sowing route. For this reason, it is often necessary for the operator to apply a large force through the hand handle to keep the drive wheel from deflecting, which increases the workload of the sowing personnel; a flow switch is installed on the seeding box, and the flow of the seed outlet can be adjusted before the sowing starts. size, so that the amount of sowing can be determined according to the needs of the farmers themselves, but the flow of seeds cannot be adjusted flexibly at any time; the depth of the main plowshare entering the soil is uncertain, and it is very easy to adjust the sowing depth mainly by the pressure exerted by the operator. Make operators feel tired and affect efficiency

Abstract

The invention discloses a four-wheel hand sowing machine, which has the advantages of good using effect, light weight, flexibility, easiness in control and the like. The structure of the four-wheel hand sowing machine comprises double driving wheels, double tail wheels, a frame, a hopper, a sowing pipe, a handle, a hand brake, an opening controller, a furrower and a main plough share, wherein thetyre type double driving wheels are connected through a through shaft and fixed at the front end of a cross beam of the frame; a sleeve for adjusting wheel distance, a spring and a pin shaft are arranged on the through shaft; a traction rod is arranged at the top of the cross beam; the hopper is fixed on the frame, and the rear end of the frame is fixed on the sowing pipe; the sowing pipe is divided into two sections, wherein the upper end of the first section of the sowing pipe is connected with the handle, the lower end of the second section of the sowing pipe is fixedly connected with the main plough share and the furrower, and the double tail wheels are fixed on the first section of the sowing pipe through a connecting rod; an iron sheet of the opening controller is tightly attached to the upper end of a seed outlet on the wall of the hopper through an adjusting screw; and the operating end of the hand brake is fixed below the handle, a lever is arranged at the acting end of the hand brake and connected with a brake lining in the hopper, and the operating end is in contact with the acting end through a cam.

Description

Technical field [0001] The invention relates to a four-wheel type hand-held planter, which belongs to the field of agricultural machinery. Background technique [0002] At present, my country's planters are dominated by traditional grain planters, and planters and power planters matched with small tractors dominate. Due to economic reasons and terrain restrictions, there are still fewer tractor planters, and planters that are pulled by manpower or accumulating power are still commonly used. This kind of hand-held planter is simple in structure, convenient to use, and economical. It is available in rural areas. It is widely used; but there are still some areas for improvement. For example, the driving wheel is usually made of steel, and the driving resistance of the planter is increased if the weight is too large. In order to save material and control weight, it is impossible to use a driving wheel with a larger diameter. This makes the bearings at both ends of the driving wheel ...
