Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery equipment, in particular to a seed metering device for a drill seeder and a drill seeder with the same. Background Art

[0002] The seed guiding pipe frame of a drill seeder is a device for fixing the seed guiding pipe. Before operation, when calibrating the seeds, the 24-row seed guiding pipe is separated from the fluted wheel metering device, and a hopper is connected so that all the seeds fall into the hopper, and the seeding rate is calculated by weighing.

[0003] At present, during the overall lifting and falling process of the 24-row seed guiding pipe of the existing drill seeder, it is quite laborious. The specific structure is as follows: there are independent spring pulling devices on both sides, the seed guiding pipe frame is connected to the springs, the limit shaft is pulled out, and the seed guiding pipe frame falls, so that the limit shaft is inserted into the bottom hole position to complete the positioning; when the seed guiding pipe frame rises, the limit shaft is pulled out, and the seed guiding pipe frame is pulled up by the spring force at the rear to achieve the purpose of saving effort. In the actual operation process, when the seed guiding pipe frame falls, due to the spring force, it is quite laborious during the falling process; during the lifting process, both sides need to apply force simultaneously, that is, two people are required to operate, which is rather troublesome. Moreover, the direction of the applied force is inconsistent with the moving direction of the seed guiding pipe frame, which is rather laborious. In addition, the spring plays a negative role during the falling process and has little effect during the lifting process. Therefore, the overall operation is rather laborious.

[0025] The principles and features of the present utility model are described below in conjunction with the attached drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0026] Embodiment 1

[0027] As shown in Figure 1 , 2 , 3 ( Figure 1 a part of the hopper 5 is removed in the figure), the seed metering device of the dibbler in this embodiment includes a seed box 1 and a seed metering device 2. A seed discharging port extending towards both ends is provided at the lower end of the seed box 1, and the seed metering device 2 is installed at the seed discharging port. It also includes a seed guide pipe rack 3, a plurality of seed guide pipes 4, a hopper 5, and a crank moving mechanism 6. The seed guide pipe rack 3 is arranged below the seed metering device 2, and both ends of the seed guide pipe rack 3 are horizontally slidably connected to the side plates at both ends of the seed box 1 respectively. A plurality of the seed guide pipes 4 are respectively installed in the seed guide pipe rack 3 and are arranged in a row at intervals below the seed metering device 2. The hopper 5 is installed on one side of the seed guide pipe rack 3, and the crank moving mechanism 6 is installed on the side plates at both ends of the seed box 1 and is connected to the other side of the seed guide pipe rack 3. The crank moving mechanism 6 is used to drive the seed guide pipe rack 3 to drive the seed guide pipes 4 and the hopper 5 to move horizontally, and to make the seed guide pipes 4 and the hopper 5 alternately located below the seed metering device 2.

[0028] The seed metering device of the dibbler in this embodiment has the following two working modes:

[0029] 1) As shown in Figure 2 ( Figure 2The middle seed guiding tube 4 is not shown. Under normal operation, multiple seed guiding tubes 4 are located below the seed metering device 2. The multiple seed guiding tubes 4 are arranged in a row below the two ends of the seed box 1. The seeds coming down from the seed metering device 2 fall downward after passing through the multiple seed guiding tubes 4.

[0030] 2) As shown in Figure 3 For the calibration operation, the crank moving mechanism 6 is used to drive the seed guiding tube rack 3 to translate toward the other side of the seed box 1. In this way, the seed guiding tube rack 3 drives the seed guiding tubes 4 to move to the lower side of one side of the seed metering device 2. At the same time, the hopper 5 is located below the seed metering device 2. Rotate the ground wheel of the drill seeder to reach the specified number of turns. Take out the hopper 5 from one side, weigh the weight of the seeds received, and complete the calibration through public formula calculation.

[0031] After the calibration is completed, the crank moving mechanism 6 drives the seed guiding tube rack 3 to move back to its original position, and keeps the seed guiding tubes 4 below the seed metering device 2, then the operation can start to achieve the accurate seeding rate required by the user.

[0032] As a preferred embodiment, on the mutually approaching surfaces of the side plates at both ends of the above-mentioned seed box 1, there are respectively provided horizontally extending guide rails 11, and both ends of the above-mentioned seed guiding tube rack 3 are respectively slidably connected to the above-mentioned guide rails 11.

[0033] In the above-mentioned implementation scheme, the side plates at both ends of the seed box 1 extend downward, and both ends of the seed guiding tube rack 3 are respectively slidably connected to the guide rails 11 provided on the side plates at both ends, which can ensure that the seed guiding tube rack 3 drives the seed guiding tubes 4 and the hopper 5 to translate quickly under the drive of the crank moving mechanism 6. The operation process is relatively stable.

[0034] As a preferred embodiment, two of the above-mentioned guide rails 11 are respectively provided on the side plates at both ends of the above-mentioned seed box 1, and the two above-mentioned guide rails 11 are distributed at intervals up and down.

[0035] In the above-mentioned implementation scheme, the design of the two guide rails 11 makes the sliding assembly at both ends of the seed guiding tube rack 3 very stable and not prone to shaking.

[0036] In this embodiment, the above-mentioned guide rail 11 is a strip-shaped groove provided on the side plates at both ends of the above-mentioned seed box 1, and both ends of the above-mentioned seed guiding tube rack 3 are respectively provided with sliding short columns 31 that fit into the above-mentioned guide rail 11. The sliding short columns 31 are perpendicular to the side plates, and the ends are embedded in the strip-shaped grooves, so that they can effectively translate along the strip-shaped grooves under the action of external forces.

[0037] In this embodiment, the above-mentioned seed guiding tube rack 3 is a long rectangular frame, and the seed guiding tubes 4 are assembled inside.

[0038] As a preferred embodiment, the upper part of one side end of the above-mentioned hopper 5 is hinged to the upper part of one side of the above-mentioned seed guiding tube rack 3, and the above-mentioned hopper 5 can be turned up and down under the action of external forces.

[0039] In the above embodiment, such a design is adopted that when the seed guide tube 4 is located below the seed metering device 2, the hopper 5 is flipped upward, and the other side thereof is just close to the outside of one side of the seed box 1. Then the other side of the hopper 5 can be fixed to reduce the volume. When proofreading is required, an external force flips the hopper 5 downward so that one side of the hopper 5 is against one side of the seed guide tube rack 3. Then, the crank moving mechanism 6 is driven to drive the seed guide tube rack 3 and the hopper 5 to move, so that inoculation is carried out below the seed metering device 2 while the hopper 5 is moving.

[0040] As a preferred embodiment, one side of the seed box 1 is provided with a fixture adapted to the other side of the seed guide tube rack 3, and the hopper 5 can be flipped upwards and the other side thereof is connected to the fixture.

[0041] In the above embodiment, the function of the fixer is to flip the hopper 5 upwards and connect and maintain the other side of the hopper 5 to one side of the seed box 1 when the seed guide tube 4 is normally seeded.

[0042] More specifically, the fastener can be a structure of a hook and a hanging ring, the hanging ring is installed on the outer surface of one side of the seed box 1, and the hook is installed on the other side of the hopper 5. After the hopper 5 is flipped upward, the other side of the hopper 5 is close to the hanging ring and can be hung with the hanging ring through the hook on the other side.

[0043] In this embodiment, a rotating shaft is provided on the upper part of one side of the seed guide tube rack 3, and a hook connected to the rotating shaft is provided on one side of the hopper 5, and the two are hinged by the connection between the hook and the rotating shaft.

[0044] As a preferred embodiment, the crank moving mechanism 6 includes a first crank 61, a second crank 62 and a driving member 63, one end of the first crank 61 is vertically rotatably connected to the side plate of any one end or both ends of the seed box 1 through a first rotating pin 611, one end of the second crank 62 is rotatably connected to the other end of the first crank 61 through a second rotating pin (represented by b in the figure), and the other end of the second crank 62 is rotatably connected to the mounting portion arranged on the other side of the seed guide tube rack 3 through a third rotating pin (represented by c in the figure), and the driving member 63 is detachably connected to the first rotating pin 611, and is used to drive the first rotating pin 611 to rotate, and drive the first crank 61, the second crank 62, the seed guide tube rack 3 and the hopper 5 to be linked.

[0045] In the above embodiment, the first crank 61 can be rotated by driving the first rotating pin 611 to rotate through the driving member 63. When the first crank 61 rotates, the second crank 62 can be pushed and pulled, so that the second crank 62 pushes and pulls the seed guide tube rack 3 to translate relative to the two end side plates of the seed box 1. The design is relatively ingenious, and the operation is simple and quick.

[0046] In this embodiment, the translation stroke end point and start point of the seed guiding pipe support 3 are defined by setting the length of the guide rail 11. Among them, the start point of the guide rail 11 is close to one side of the seed box 1, and the end point is close to the other side of the seed box 1. When the seed guiding pipe 4 is located below the seed metering device 2, the connection point (sliding short column 31) between the seed guiding pipe support 3 and the guide rail 11 is located at the start point of the guide rail 11. When the hopper 5 is located below the seed metering device 2, the connection point (sliding short column 31) between the seed guiding pipe support 3 and the guide rail 11 is located at the end point of the guide rail 11. The specific force analysis is as follows:

[0047] As Figure 4 shown, assume that the axis center of the first rotating pin 611 is point A, the hinge point of the first crank 61 and the second crank 62, that is, the axis center of the second rotating pin is point B, and the rotating connection point (i.e., the rotation center) between the second crank 62 and the installation part of the seed guiding pipe support 3 is point C. When the seed guiding pipe 4 is located below the seed metering device 2 (that is, the sliding short column 31 is located at the start point of the guide rail 11), the included angle between the line connecting point A and point B and the line connecting point B and point C is α, 167° ≤ α ≤ 170° (the best is 169°), and the included angle between the line connecting point B and point C and the horizontal line where the guide rail 11 is located is β, 175° ≤ β ≤ 178° (the best is 176°). Taking the best values of α and β, the following formula is used to analyze the force:

[0048] Fc = fcos(180 - 176)

[0049] Fb = Fc

[0050] Fb = fcos(180 - 176);

[0051] Fb = Fb′cos(90 - 180 + 169)

[0052] M = Fb′·Lab

[0053] So M = f·cos(180 - 176) / cos(90 - 180 + 169)·Lab = 0.49f

[0054] Among them, both Fb and Fc fall on the BC line or its extension line, the direction of Fb′ is perpendicular to the AB line, and Lab is the length of the AB line. Through force analysis, it can be obtained that the torque required to rotate the rocker is much smaller than the friction force of the slider itself. Therefore, this solution can achieve the purpose of saving effort and being convenient.

[0055] Therefore, in the seed alignment device of the drill seeder in this embodiment, the design of the crank moving mechanism 6 is relatively ingenious and the operation is relatively labor-saving.

[0056] As a preferred embodiment, the above-mentioned first rotating pin 611 penetrates through the side plates at any one end or both ends of the above-mentioned seed box 1, and a hexagonal column is provided at the end. The above-mentioned driving member 63 is a Z-shaped crank. An internal hexagonal blind hole adapted to the above-mentioned hexagonal column is provided at one end of the crank. One end of the crank is sleeved outside the above-mentioned hexagonal column, and the first rotating pin 611 is driven to rotate under the action of an external force.

[0057] In the above-mentioned implementation scheme, during operation, insert the internal hexagonal blind hole at one end of the crank into the hexagonal column at the end of the first rotating pin 611, and the first rotating pin 611 can be driven to rotate by rotating the crank, so as to realize the displacement of the seed guiding tube 4 and the hopper 5, that is, to realize the separation of the seed guiding tube frame 3 and the seed metering device 2.
