Description

Crop seeder convenient to control seeding amount

Technical Field

The invention relates to the technical field of sowing machines, in particular to a crop sowing machine convenient for controlling sowing quantity.

Background

The sowing quantity refers to the weight or the quantity of seeds sown in a unit area (such as mu or square meter) in agricultural production. The determination of the amount of seeding needs to take into account a number of factors including the number of basic seedlings planned, thousand seed weight of the seeds, germination rate, field emergence rate, soil fertility and moisture content, time of seeding, etc. Proper seed quantity is critical to ensure the yield and quality of crops. Different crops and planting environments may require different seed amount adjustments. With the development of science and technology, seeds are sowed by a sowing machine, and the mode of planting crops is replaced by artificial sowing. The seeder is a modern agricultural device, and is mainly used for improving planting efficiency and crop yield and reducing fatigue strength. The seeding depth, the seed spacing, the seeding quantity and other parameters are accurately controlled, so that seeds can be uniformly and accurately planted in soil, the seeds can be prevented from being eaten by birds and animals or being dried due to exposure to sunlight, and the germination rate of the seeds and the uniformity of crops are improved. In addition, the seeder is also suitable for different farmland soil properties, can be adjusted according to different soil conditions, and can realize quantitative and uniform seeding under various soil conditions. In the prior art, the seed sowing machine usually completes single seed collection and subsequent discharge sowing through the seed sowing plate and the seed grooves on the seed sowing plate, but different types of seeds have different shapes, meanwhile, the sizes of the seed grooves on the seed sowing plate have certain gaps, and the seed grooves on the seed sowing plate are all required to be adjusted according to the sizes and the shapes of the seeds and accord with the sizes of the seeds so as to discharge the seeds. When the seed grooves are different, the discharge of seeds can not be confirmed, even if the seeds of the same type have individual size differences, single seeds or multiple seeds can be blocked in the seed grooves and cannot be left up or down when entering the seed grooves on the seed metering disc, so that the condition of missing sowing and multicasting is caused in the sowing process, the control of the sowing quantity is influenced, the integral sowing uniformity is influenced, and the integral sowing condition is influenced.

When the user needs to sow, the user needs to determine whether the shape of the seeds meets the requirement, such as the crop seeds of peanuts, soybeans and the like which are round or oval, and determine the average diameter of the seeds to be sown, then input and record the seeds through the console 12, then the console 12 drives the first electric slide block 45 to start, and the movement of the first electric slide block 45 drives the movement of the limiting circular plate 46, so that one end of the limiting circular plate 46 begins to squeeze the part of the conveying hose 32 which is not provided with the limiting plate 50, the part of the conveying hose 32 which is not provided with the limiting plate 50 is deformed by squeezing, So as to limit the caliber of the part of the conveying hose 32 without the limiting plate 50, after the limiting circular plate 46 moves, the space of the crossing part of the three limiting circular plates 46 is equal to the average diameter of seeds input in advance, so that the part of the conveying hose 32 extruded by the limiting circular plate 46 can just pass through the range of one seed, the subsequent operation is convenient, meanwhile, the second electric slide block 61 starts to start under the action of the console 12, the second electric slide block 61 drives the limiting plate 50 to move towards the center of the conveying hose 32 after being started until the second electric slide block 61 moves for a certain distance, The distance between the limiting plates 50 after moving is also equal to the average diameter of the seeds inputted previously, the conveying hose 32 between the limiting plates 50 is pulled by the pulling rope 49, so as to keep the shape of the conveying hose 32 stable, then the motor No. two 37 is started under the action of the console 12, the motor shaft of the motor No. two 37 will drive the pulley No. two 35 to rotate after being started, so that the pulley No. one 34 is driven to rotate by the driving belt 36, and along with the rotation of the pulley No. one 34, the fixing post 48 on the pulley No. one 34 will rotate together, thereby driving the part of the conveying hose 32 pulled by the pulling rope 49 to rotate together, so that the surplus part of the conveying hose 32 pulled by the pulling rope 49 is wound on the surface of the limiting plate 50 under the action of the rotation of the first belt wheel 34, the surplus gap is reduced, the subsequent falling of seeds is facilitated, the electric push rod 38 is started under the action of the

limiting plate 50), then the oil pump 15 is started by a user through the control console 12, so that under the action of the control console 12, the oil in the oil pump 15 enters the hydraulic telescopic rod 17 through the oil delivery pipe 16, the ditching disc 24 enters the ground to facilitate the subsequent operation, then the user can throw the seeds of the required seeds into the seed temporary storage bin 19, the seeds in the seed temporary storage bin 19 fall into the first-stage hopper 27 under the action of gravity, the first-stage hopper 27 falls into the conveying hose 32, the seeding vehicle 11 is started by a user to start moving, the first motor 41 is started under the action of the console 12, the motor shaft of the first motor 41 drives the second gear 42 to rotate after being started, the second gear 42 drives the first gear 28 to rotate, the first gear 28 drives the threaded plate 43 to rotate through the limiting rod 52 along with the rotation of the first gear 28, the threaded plate 43 starts moving towards the first gear 28 under the cooperation of the threads of the fixed threaded sleeve 29, so that the screw plate 43 is in the condition of rising while rotating, and the position between the limit circular plates 46 is limited in advance, the limit circular plates 46 can synchronously rotate and rise under the action of the screw plate 43, and the pushing balls 47 on the limit circular plates 46 squeeze all seeds out of the overlapped parts of the three limit circular plates 46 in the process of rising while rotating, so that only one vertical row of seeds in the overlapped parts of the three limit circular plates 46 is left, thereby enabling the seeds to smoothly pass, preventing clamping and guaranteeing seed output, and the first motor 41 is a stepping motor, When the screw plate 43 is in contact with the first gear 28, the first motor 41 will rotate reversely after running for a certain time, so that the screw plate 43
