[0002] The sowing device used in agricultural planting is a mechanical device used for sowing in farmland. Its main function is to spread seeds evenly in the farmland to achieve seed placement. Using the sowing device to sow soybeans can ensure the planting density and leaf area of ​​the crop through precise sowing control, improve the utilization rate of cultivated land, thereby increasing crop yield and quality, and greatly reducing the labor intensity of the staff.

[0003] In the prior art, in order to evenly sow soybean seeds in the farmland, a seed delivery mechanism is set at the discharge end of the seed storage silo. The delivery mechanism is controlled by a programmed program to move at the output end of an actuator such as a motor or a cylinder, so as to realize automatic intermittent opening and closing of the delivery mechanism. When it is opened, sowing and feeding are carried out, and when it is closed, sowing is stopped, thereby completing the quantitative delivery of seeds.

[0004] However, the above design still has some shortcomings. When sowing, the driver is required to operate the sowing device to move. Due to the driver's lack of operating experience or improper operation, the sowing device cannot maintain a uniform speed. Since the delivery mechanism opens and closes at regular intervals, the distances between the delivered seeds are different, resulting in different distances between subsequent plants, which makes some plants unable to receive sufficient light, affecting crop growth and the use effect is not ideal. Utility Model Content

[0005] The utility model provides a sowing device for agricultural planting, and aims to solve the problem that: in the existing sowing devices for agricultural planting, the distances between the seeds dropped are different, resulting in different spacings between subsequent plants, so that some plants cannot receive sufficient light, affecting the growth of crops and the use effect is not ideal.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Refer to the instruction manual Figures 1 to 6 A sowing device for agricultural planting, comprising a frame 1, a sowing mechanism 2 is arranged on the frame 1, and the frame 1 is used to drive the sowing mechanism 2 to move; the sowing mechanism 2 comprises a silo 21, and the silo 21 is used to store seeds, and a disc 22 is rotatably arranged in the silo 21, and a material dividing trough 221 is opened on the disc 22; a transmission mechanism 3 is arranged on the frame 1, and the transmission mechanism 3 comprises a driving shaft 31, and the disc 22 is fixedly arranged on the driving shaft 31, and the movement of the frame 1 synchronously drives the driving shaft 31 to rotate, and the driving shaft 31 drives the disc 22 to rotate, and the rotation of the disc 22 is used to sow the seeds in the material dividing trough 221.

[0027] It should be noted that a cover plate is rotatably provided on the silo 21 , and the cover plate is used to shield the interior of the silo 21 to prevent impurities such as gravel particles from entering the silo 21 .

[0028] It should also be noted that a rotating drive is installed outside the silo 21 or on the frame 1, and the rotating drive is configured as a motor. Pulleys are fixedly provided on the output shaft of the motor and the driving shaft 31, and the two pulleys are connected by the same belt drive. The rotation of the motor output shaft realizes the effect of driving the driving shaft 31 to rotate.

[0029] The specific implementation scenario is: the device is placed in a farmland, and a tractor or other driving device is used as a driving source to drive the frame 1 to move. The frame 1 is fixed to the driving source device, and the soybean seeds to be sown are loaded into the silo 21. The soybean seeds have been sorted by a screening machine, and the soybeans do not contain defective seeds or impurities. When the silo 21 is filled with the required amount of seeds, some seeds fall into the dividing trough 221, and the frame 1 is driven to move by the driving source device. During the movement of the frame 1 on the farmland, the motor output shaft drives the disc 22 to rotate. When the disc 22 rotates 90°, the seeds in the dividing trough 221 fall under the action of gravity, thereby achieving the effect of automatic sowing.

[0030] Refer to the instruction manual Figure 1 and Figure 2 In the process of the frame 1 moving in the farmland, in order to prevent the frame 1 from pressing uneven dents on the surface of the farmland, specifically, the frame 1 includes a supporting beam 11, a connecting shaft is rotatably provided on the supporting beam 11, a roller 12 is fixedly provided on the connecting shaft, and a traction frame is fixedly provided on the supporting beam 11.

[0031] It should be noted that the roller 12 includes three circular rings, on which a plurality of convex plates arranged at equal intervals are fixedly arranged. The convex plates are used to contact the soil on the surface of the farmland. Since the contact area between the convex plates and the soil is small, serious crushing marks on the soil are avoided during the movement of the frame 1.

[0032] It should also be noted that the support beam 11 is fixed to the driving source device by a traction frame, which is convenient for disassembly and installation of the support beam 11 .

[0033] Refer to the instruction manual Figures 1 to 4 In order to ensure the fluidity and uniformity of the soybean seeds in the silo 21, specifically, the sowing mechanism 2 includes a mounting frame, the silo 21 is fixedly arranged on the supporting beam 11, a stirring rod 23 is rotatably arranged in the silo 21, a baffle 24 is fixedly arranged in the silo 21, the baffle 24 is adapted to the disc 22, a discharge pipe 25 is fixedly connected to the bottom end of the silo 21, a discharge hopper 26 is fixedly arranged on the mounting frame, and the bottom end of the discharge pipe 25 is located in the discharge hopper 26.

[0034] It should be noted that a motor is fixedly mounted on the silo 21 , an output shaft of the motor is extended into the silo 21 , and a stirring rod 23 is fixedly mounted on the output shaft of the motor.

[0035] It should also be noted that, during the process of the support beam 11 driving the silo 21 to move, the motor drives the stirring rod 23 to rotate, and the stirring rod 23 stirs the soybean seeds in the silo 21 to improve the fluidity and uniformity of the soybean seeds in the silo 21. The disc 22 rotates in the silo 21. After the soybean seeds enter the dividing trough 221, the baffle 24 and the surface of the disc 22 are adapted to push the excess soybean seeds in the dividing trough 221 to one side to prevent blockage in the dividing trough 221.

[0036] Refer to the instruction manual Figures 1 to 4 , to sow seeds, in order to automatically adjust the soil on the surface of the farmland so that the seeds can be efficiently buried in the soil, specifically, a plowshare 27 is fixedly provided on the mounting frame, the bottom end of the lower hopper 26 is adapted to the plowshare 27, the bottom end of the lower hopper 26 is located at the middle position of the plowshare 27, and a leveling roller 28 and a leveling roller 29 are rotatably provided on the mounting frame.

[0037] It should be noted that when the supporting beam 11 drives the mounting frame to move, the leveling roller 28 first contacts the soil of the farmland to roll the soil and trim the uneven soil, and then the plowshare 27 moves to plow pits on the surface of the soil, and the feed pipe 25 puts seeds into the pits, and then the leveling roller 29 trims the ground and backfills the pits, so that the seeds are automatically buried in the soil, thereby improving the sowing efficiency.

[0038] Refer to the instruction manual Figures 1 to 3 When the roller 12 rotates, in order to drive the disc 22 and the roller 12 to rotate synchronously and avoid uneven sowing due to uneven moving speed of the driving equipment, specifically, the transmission mechanism 3 includes a second driving shaft 32, the second driving shaft 32 is rotatably arranged with the silo 21, the stirring rod 23 is fixedly arranged on the second driving shaft 32, the first driving shaft 31 is rotatably arranged on the supporting beam 11, the first driving shaft 31 and the second driving shaft 32 are both fixedly provided with pulleys 33, the two pulleys 33 are connected by belt transmission, and the connecting shaft and the first driving shaft 31 are both fixedly provided with sprockets 34, and the two sprockets 34 are connected by chain transmission.

[0039] It should be noted that when the roller 12 rotates, the transmission chain through the sprocket 34 is that the sprocket 34 and the roller 12 rotate synchronously, and the rotation of the sprocket 34 drives the disc 22 to rotate, thereby achieving the effect of uniform feeding and sowing. The rotation of the drive shaft 1 31 drives the pulley 33 installed on its outer side to rotate, and the pulley 33 drives the drive shaft 2 32 to rotate. The rotation of the drive shaft 2 32 drives the stirring rod 23 to rotate, which not only achieves the purpose of synchronous sowing with the rotation of the roller 12, but also reduces the driving source and reduces the production cost of the equipment.

[0040] Refer to the instruction manual Figures 1 to 6 Since the selected soybean seeds are all high-quality seeds, and the high-quality seeds are larger in size, in order to prevent the seeds from being stuck in the dividing trough 221 and being unable to be sown by falling due to gravity, specifically, a filter screen 222 is fixedly arranged on the inner wall of the dividing trough 221, an annular groove 224 is provided on the front side of the dividing trough 221, an exhaust hole 223 is provided on the inner wall of the annular groove 224, and the exhaust hole 223 is connected to the dividing trough 221, and an exhaust hole 225 is provided on the inner wall of the annular groove 224, and the exhaust hole 225 is connected to the edge of the disc 22, and a negative pressure pump is fixedly arranged on the silo 21, and the exhaust end of the negative pressure pump is in contact with the inner wall of the annular groove 224.

[0041] It should be noted that a guide plate is fixedly provided in the silo 21, and the second exhaust hole 225 is connected to the edge of the disc 22. Since the second exhaust hole 225 and the guide plate are provided, when the exhaust end of the negative pressure pump does not coincide with the first exhaust hole 223, the wind force generated by the negative pressure pump is discharged through the second exhaust hole 225, and the second exhaust hole 225 guides the wind force to the bottom of the silo 21 and is discharged through the bottom end of the discharge pipe 25. The wind force generated by the negative pressure pump will not blow the seeds in the silo 21, and can prevent the seeds in the silo 21 from floating.

[0042] It should also be noted that when sowing is carried out by rotating the disc 22, the negative pressure pump is started, the negative pressure pump absorbs external air, and discharges the absorbed gas through its discharge end. When the discharge end of the negative pressure pump coincides with the exhaust hole 223, the wind is discharged through the dividing trough 221. The wind force in the dividing trough 221 blows the seeds in the dividing trough 221, and the seeds are prevented from being stuck in the dividing trough 221 under the action of gravity. At the same time, the wind force can also clean the dust and impurities stuck in the dividing trough 221 to prevent the dividing trough 221 from being blocked by dust.

[0043] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
