Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and relates to a seeding machine, especially an electric seeding machine. Background Technology

[0002] In agricultural planting, broadcasters are often used for sowing. Existing broadcasters are mainly hand-push type suitable for small-area sowing or PTO shaft drive type suitable for connecting to tractors on large areas of land. This drive method depends on the tractor's travel speed to control the rotation speed of the dial, which has poor stability and is prone to throwing seeds off the intended path.

[0003] In addition, the discharge channel of traditional broadcasters cannot control the even drop of seeds, which leads to uneven sowing density and makes it easy for seedlings to be missing or clustered after germination. Since there is no additional device to guide the seeds inside the seed bin of traditional broadcasters, the seed bin is prone to lack of flow when there are too many seeds, which can block the discharge port and cause large-scale seedling loss.

[0004] Therefore, it is necessary to provide a seed broadcaster that is not prone to clogging the seed chamber outlet, has a uniform discharge speed, and can throw the seeds out at a uniform speed to improve the sowing quality. Utility Model Content

[0005] The purpose of this utility model is to provide an electric seeder to solve the technical problems existing in the prior art, such as the inability to uniformly throw seeds to a predetermined route, uneven seed discharge, and easy clogging of the seed bin discharge port.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] An electric seeding machine includes a seed bin, a discharge channel, a dial, and a traction frame. The seed bin is fixed to the rear end of the traction frame. The discharge channel is located below the seed bin. The dial is located below the discharge port of the discharge channel. The machine also includes a power drive mechanism, a dial, and a flow guiding mechanism. The front end of the traction frame is connected to the rear end of an ATV vehicle. The power drive mechanism is located below the discharge channel and fixed to the traction frame.

[0008] The discharge channel is cylindrical, and the flow guiding mechanism includes a flow guiding shaft and a flow guiding plate spirally arranged in the middle of the flow guiding shaft. The flow guiding shaft is coaxially arranged with the discharge channel. The lower end of the flow guiding shaft is connected to the power output end of the power drive mechanism, the middle part with the flow guiding plate extends into the discharge channel, and the upper end extends into the seed bin.

[0009] The dial is located at the lower end of the flow guide shaft and is connected to the power drive mechanism via the flow guide shaft.

[0010] The flow guiding mechanism also includes a baffle plate, which is an obtuse-angled arc plate. The lower end of the baffle plate is fixed to the upper end of the flow guiding shaft, and the upper end extends away from the axis of the flow guiding shaft.

[0011] The number of the baffles is multiple, and the multiple baffles are evenly arranged around the circumference of the flow guide shaft.

[0012] The power drive mechanism includes a drive motor, a drive mounting box, and a control box. The drive mounting box is fixed on the rear side of the towing frame. The control box is electrically connected to the drive motor and the power supply of the ATV vehicle. The drive motor is housed inside the drive mounting box, and its power output end extends out of the drive mounting box and is connected to the guide shaft for transmission.

[0013] The drive motor is a variable frequency motor.

[0014] It also includes a baffle plate, which is fixed to the top of the power drive mechanism near the traction frame. The baffle plate includes an arc-shaped baffle and a guide baffle. The arc-shaped baffle is coaxially arranged with the dial. The guide baffle is integrally formed with the arc-shaped baffle and is arranged on both sides of the arc-shaped baffle. The outer side of the guide baffle extends out of the power drive mechanism.

[0015] The arc-shaped baffle has an arc of 120°-180°.

[0016] The beneficial effects of this utility model are as follows: This utility model provides an electric seeder, which replaces the traditional method of using PTO transmission to drive the dial rotation with an external power source powered by the battery of an ATV vehicle or other vehicle to drive the dial rotation. The motor drives the dial to rotate at a uniform speed, which can effectively ensure that the seeds falling from the discharge channel receive uniform centrifugal force on the dial, so that they fall neatly in the same straight line range, thereby improving the uniformity of the seedling position in the later stage.

[0017] Furthermore, by setting a guide mechanism in the discharge channel, the rotation of the guide vanes drives the seeds to fall, effectively controlling the uniformity of seed fall and thus ensuring uniform seed sowing density. The selection of a variable frequency motor for the drive motor allows for adjustment of the motor speed according to sowing needs, thereby adjusting the sowing density. On this basis, by setting a baffle at the upper end of the guide shaft, the baffle can be driven to stir at the discharge port at the bottom of the seed bin while the guide shaft and guide vanes are rotating, effectively preventing seeds from accumulating at the bottom of the seed bin and clogging the discharge port.

[0018] The technical solution provided by this utility model can significantly improve the straightness of the sowing position and effectively control the sowing density, avoiding seed blockage of the seed chamber outlet, and is suitable for widespread application in broadcast sowing.

[0026] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this utility model provides an electric seeding machine, including a seed bin 2, a discharge channel 3, a dial 4, and a traction frame 1 constituting the main body of the seeding machine. The front end of the traction frame 1 is fixedly connected to the rear end of an ATV vehicle, and is towed by an ATV vehicle or other vehicles that can be equipped with an external battery power supply 12. The seed bin 2 is fixed to the rear end of the traction frame 1. The discharge channel 3 is located below the seed bin 2, and the dial 4 is located below the discharge port of the discharge channel 3.

[0028] Based on the above, the electric seeder in this embodiment also includes a power supply 12 drive mechanism, a dial 4, and a flow guiding mechanism 5, such as... Figures 1 to 4 As shown. The power supply 12 drive mechanism is located below the discharge channel 3 and is fixed to the traction frame 1 to drive the flow guiding mechanism 5 and the dial 4.

[0029] The discharge channel 3 connected to the discharge port of seed bin 2 is cylindrical. The flow guiding mechanism 5 includes a flow guiding shaft 6 and a flow guiding plate 7 spirally arranged in the middle of the flow guiding shaft 6, such as... Figure 6As shown, the outer edge of the guide vane 7 is clearance-fitted with the discharge channel 3. The guide shaft 6 is coaxially arranged with the discharge channel 3. The lower end of the guide shaft 6 is connected to the power output end of the power supply 12 drive mechanism, the middle part where the guide vane 7 is located extends into the discharge channel 3, and the upper end extends into the seed chamber 2. Under the drive of the guide shaft 6 and the power supply 12 drive mechanism, the guide vane 7 rotates around the axis of the guide shaft 6, causing the seeds in the discharge channel 3 to fall at a uniform speed.

[0030] In order to fling the fallen seeds into the soil, in this embodiment, the dial 4 is located at the lower end of the guide shaft 6 and is connected to the power supply 12 drive mechanism via the guide shaft 6. Figure 3 , Figure 5 As shown.

[0031] Furthermore, to prevent seeds from clogging the outlet of the seed chamber 2 during the sowing process, causing the dial 4 and guide vane 7 to idle, the guide mechanism 5 in this embodiment also includes a baffle 8, such as... Figure 6 As shown, the baffle plate 8 is an obtuse-angled arc-shaped plate with a certain curvature. The lower end of the baffle plate 8 is fixed to the upper end of the guide shaft 6, and the upper end extends away from the axis of the guide shaft 6. Driven by the guide shaft 6, the baffle plate 8 rotates, thereby agitating the seeds at the bottom of the seed chamber 2 and preventing them from clogging and accumulating. The number of baffle plates 8 can be one or more. In this embodiment, there are two, and the two baffle plates 8 are evenly arranged around the circumference of the guide shaft 6.

[0032] Furthermore, such as Figure 4 As shown, the power supply 12 drive mechanism in this embodiment includes a drive motor 9, a drive mounting box 10, and a control box 11. The drive mounting box 10 is fixed to the rear side of the traction frame 1. The control box 11 is electrically connected to both the drive motor 9 and the external power supply 12 of the ATV vehicle battery, and is used to control the drive motor 9. The drive motor 9 is housed inside the drive mounting box 10, and its power output end extends out of the drive mounting box 10 and is connected to the guide shaft 6 for transmission. To facilitate the adjustment of the speed of the drive motor 9 and thus the seed sowing density, the drive motor 9 in this embodiment is selected as a variable frequency motor.

[0033] Furthermore, to prevent seeds from being thrown off course after falling onto the dial 4, a baffle plate 13 is provided on the side of the dial 4 near the traction frame 1 in this embodiment. The baffle plate 13 is fixed to the top of the drive mounting box 10 and includes an arc-shaped baffle 131 and a guide baffle 132. Figure 3 , Figure 5As shown, the arc-shaped baffle 131 is coaxially arranged with the dial 4 to prevent seeds from being thrown onto the ground in the direction of the traction frame 1. The arc of the arc-shaped baffle 131 is 120°-180°, preferably 120°, which ensures that the seeds are thrown to the side of the broadcaster. The guide baffle 132 is integrally formed with the arc-shaped baffle 131 and is arranged on both sides of the arc-shaped baffle 131. The guide baffle 132 extends outward from the arc, and the extension direction forms an angle of 0-45° with the tangent direction of the arc-shaped baffle 131, preferably 30°. Furthermore, the outer side of the guide baffle 132 extends outside the power supply 12 mounting box, thereby preventing the seeds from being thrown behind the broadcaster due to the excessive rotation speed of the dial 4.
