Description

Technical Field

[0001] The utility model relates to the technical field of a seed guiding pipe frame of a seeding machine, in particular to a separating device for a seed guiding pipe frame and a drill seeder. Background Art

[0002] The seed guiding pipe frame of a drill seeder is a device for fixing the seed guiding pipe. The seed guiding pipe frame is located below the fluted wheel metering device, and multiple seed guiding pipes in a row are fixed on the seed guiding pipe frame. Before operation, seed calibration is required. At this time, the seed guiding pipe frame needs to be moved to separate the seed guiding pipe from the fluted wheel metering device, so that the seeds of the fluted wheel metering device fall into the hopper, and the seeding rate is calculated by weighing.

[0003] The currently commonly used structure is that the seed guiding pipe frame can slide up and down along the side of the frame. The two sides of the frame are respectively connected to the seed guiding pipe frame through independent spring lifting devices and limiting shafts. When the limiting shaft is pulled out, the seed guiding pipe frame drops to the bottom of the frame, and then the limiting shaft is inserted into the limiting hole at the bottom of the frame to fix the seed guiding pipe frame for seed calibration. After the seed calibration is completed, the limiting shaft is pulled out, and the seed guiding pipe frame is lifted by the combined force of manual and spring tension to achieve the purpose of labor saving. In the actual operation process, when the seed guiding pipe frame drops, due to the spring tension and the frame resistance, the descending process is prone to jamming and the movement is not smooth. During the lifting process, both sides need to exert force simultaneously, and two people need to cooperate closely, resulting in a large working intensity and inconvenient operation. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: how to realize the separation and combination movement of the seed guiding pipe frame and the fluted wheel metering device and reduce the working intensity.

[0005] The technical solution for the utility model to solve the above technical problems is as follows:

[0006] The utility model provides a separating device for a seed guiding pipe frame, including a frame, a rotating shaft, and a seed guiding pipe frame. Both ends of the rotating shaft are rotatably connected to the frame. One end of the rotating shaft is provided with a driving member capable of driving its own rotation. A crank is provided on the rotating shaft. One end of the crank is hinged to a connecting rod, and one end of the connecting rod is hinged to the seed guiding pipe frame; sliding rails are provided on the opposite inner side walls of the frame, and both ends of the seed guiding pipe frame are slidably connected to the sliding rails.

[0007] The beneficial effects of the utility model are:

[0008] By adopting the utility model, the separation and combination movement of the seed guiding pipe frame and the fluted wheel metering device is realized; the power is transmitted to the seed guiding pipe frame through the rotating shaft, the crank, and the connecting rod. The sliding rails can restrict the seed guiding pipe frame to make a horizontal or inclined linear movement, reducing the change of gravitational potential energy during the movement of the seed guiding pipe frame, with small movement resistance and reduced working intensity; only by operating the driving member can the seed guiding pipe frame be driven to move, without the need for two people to cooperate, and the operation is convenient.

[0009] Based on the above technical solutions, the present utility model can also be improved as follows.

[0010] Further, cranks are provided at both ends of the rotating shaft. Connecting rods are hinged to both cranks, and the two connecting rods are respectively hinged to both ends of the seed guiding pipe rack.

[0011] When the rotating shaft rotates, power is simultaneously transmitted to the two cranks. The two cranks simultaneously drive the two ends of the seed guiding pipe rack to move through the connecting rods, making the force on the seed guiding pipe rack symmetrical, avoiding jamming, and having good movement smoothness.

[0012] Further, both the crank and the connecting rod are located inside the frame.

[0013] There is no need to open slots on the side wall of the frame for the seed guiding pipe rack to extend, avoiding jamming caused by scraping between the seed guiding pipe rack and the frame, and reducing the process, with low manufacturing cost.

[0014] Further, a limiting arm is also provided on the connecting rod. When the connecting rod pushes the seed guiding pipe rack to move to the designed stroke, the limiting arm overlaps on the side surface of the crank.

[0015] Over - movement of the seed guiding pipe rack is avoided. At the same time, when the seed guiding pipe is separated from the fluted wheel metering device, it is avoided that the connecting rod moves to the return stroke and causes the seed guiding pipe rack to move in the return direction, with good reliability.

[0016] Further, an adjustment section is provided at one end of the connecting rod. One end of the adjustment section is hinged to the crank, and the other end of the adjustment section is fixedly connected to the connecting rod by a screw; the limiting arm is located on the adjustment section.

[0017] The total length of the adjustment section and the connecting rod is the effective length of the connecting rod, which is convenient for adjusting the effective length by replacing the adjustment section or the connecting rod, and can adapt to different models; at the same time, the limiting arm is replaced along with the adjustment section, so that the designed stroke can be adjusted, with good flexibility.

[0018] Further, a long screw hole is provided on the connecting rod. The screw passes through the long screw hole and is connected to the adjustment section, and the nut part of the screw presses the connecting rod.

[0019] By sliding the adjustment section along the long screw hole, it is convenient to adjust the total length of the adjustment section and the connecting rod. After adjustment, the nut part of the screw is used to press the connecting rod, with good stability.

[0020] Further, at least two screws and long screw holes are provided.

[0021] Rotation of the adjustment section relative to the connecting rod is avoided; at the same time, sliding of the screw relative to the long screw hole during operation is avoided; the stability is improved.

[0022] Further, the driving member is a crank handle, and at least one end of the rotating shaft extends out of the frame and is provided with a crank handle joint.

[0023] When not in use, the driving part can be detached, occupying little space and having low cost; by inserting the crank handle into the crank handle joint at the end of the rotating shaft, the rotating shaft can be driven to rotate, and the operation is convenient.

[0024] Furthermore, the slide rails are arranged horizontally and face each other.

[0025] When the seed guiding pipe rack moves, there is no change in gravitational potential energy, eliminating energy storage components such as springs, saving effort during operation, and having good movement smoothness.

[0026] The utility model provides a drill seeder, which includes a seed box and the above-mentioned seed guiding pipe rack separating device. The seed box is fixed to the top of the frame. A fluted roller metering device is provided at the lower part of the seed box. The seed guiding pipe rack is located below the fluted roller metering device. Seed guiding pipes are provided on the seed guiding pipe rack, and the number of seed guiding pipes is the same as the number of outlets of the fluted roller metering device.

[0036] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0037] Refer to the present utility model Figures 1-6 。

[0038] The present utility model provides a seed guiding pipe rack separating device, which includes a frame 1, a rotating shaft 2, and a seed guiding pipe rack 6. Both ends of the rotating shaft 2 are rotatably connected to the frame 1. One end of the rotating shaft 2 is provided with a driving member 7 capable of driving its own rotation. A crank 4 is provided on the rotating shaft 2. One end of the crank 4 is hinged with a connecting rod 5, and one end of the connecting rod 5 is hinged to the seed guiding pipe rack 6; Slide rails 3 are provided on the opposite inner side walls of the frame 1, and both ends of the seed guiding pipe rack 6 are slidably connected to the slide rails 3.

[0039] Principle:

[0040] The slide rails 3 can be arranged horizontally or obliquely, so as to restrict the horizontal movement or inclined movement of the seed guiding pipe rack 6. The rotating shaft 2, the crank 4, the connecting rod 5, the seed guiding pipe rack 6, and the slide rails 3 form a crank-slider mechanism. When the driving member 7 drives the rotating shaft 2 to rotate forward and backward, the crank 4 swings, and the connecting rod 5 transmits power to the seed guiding pipe rack 6. The seed guiding pipe rack 6 moves linearly under the constraint of the slide rails 3. The driving member 7 can be a motor or a crank handle, etc.

[0041] In a drill seeder, a seed box 20 is provided at the upper part of the frame 1. A fluted roller metering device 21 is connected to the lower part of the seed box 20. The seed guiding pipe rack 6 is located below the fluted roller metering device 21. A plurality of seed guiding pipes 61 on the seed guiding pipe rack 6 are respectively connected to a plurality of outlets of the fluted roller metering device 21. When the seed guiding pipe rack 6 moves, as Figures 1-2 shown, the seed guiding pipes 61 are separated from the fluted roller metering device 21; when the seed guiding pipe rack 6 moves in the reverse direction and returns to its original position, as Figures 3-4 shown, the seed guiding pipes 61 are connected to the fluted roller metering device 21.

[0042] By adopting the present utility model, the separation and combination movement of the seed guiding pipe rack 6 and the fluted roller metering device 21 are realized; power is transmitted to the seed guiding pipe rack 6 through the rotating shaft 2, the crank 4, and the connecting rod 5. The slide rails 3 can restrict the seed guiding pipe rack 6 to move linearly horizontally or obliquely, reducing the change of gravitational potential energy when the seed guiding pipe rack 6 moves, with small movement resistance and reduced working intensity; only by operating the driving member 7 can the seed guiding pipe rack 6 be driven to move, without the need for two people to cooperate, and the operation is convenient.

[0043] Furthermore, cranks 4 are provided at both ends of the rotating shaft 2. Connecting rods 5 are hinged on both cranks 4, and the two connecting rods 5 are respectively hinged to both ends of the seed guiding pipe rack 6.

[0044] When the rotating shaft 2 rotates, power is simultaneously transmitted to the two cranks 4. The two cranks 4 simultaneously drive the two ends of the seed guide pipe support 6 through the connecting rods 5, making the forces on the seed guide pipe support 6 symmetrical, avoiding jamming, and having good movement smoothness.

[0045] Furthermore, both the crank 4 and the connecting rod 5 are located inside the frame 1.

[0046] There is no need to open a slot on the side wall of the frame 1 for the seed guide pipe support 6 to extend, avoiding jamming caused by rubbing between the seed guide pipe support 6 and the frame 1, and reducing the manufacturing process with low manufacturing cost.

[0047] Furthermore, a limiting arm 8 is also provided on the connecting rod 5. When the connecting rod 5 pushes the seed guide pipe support 6 to move to the designed stroke, the limiting arm 8 is lapped on the side surface of the crank 4.

[0048] Note: The designed stroke is the maximum stroke specified by the designer, which can be the stroke required for the seed guide pipe support 6 when the seed guide pipe 61 is separated from the fluted wheel metering device 21.

[0049] Over - movement of the seed guide pipe support 6 is avoided. At the same time, when the seed guide pipe 61 is separated from the fluted wheel metering device 21, the connecting rod 5 moving to the return stroke causing the seed guide pipe support 6 to move in the return direction is avoided, and the reliability is good.

[0050] Furthermore, an adjustment section 9 is also provided at one end of the connecting rod 5. One end of the adjustment section 9 is hinged to the crank 4, and the other end of the adjustment section 9 is fixedly connected to the connecting rod 5 by a screw; the limiting arm 8 is located on the adjustment section 9.

[0051] The total length of the adjustment section 9 and the connecting rod 5 is the effective length of the connecting rod 5, which is convenient for adjusting the effective length by replacing the adjustment section 9 or the connecting rod 5 to adapt to different models; at the same time, the limiting arm 8 is replaced with the adjustment section 9, so that the designed stroke can be adjusted, and the flexibility is good.

[0052] Furthermore, a long screw hole 10 is provided on the connecting rod 5. The screw passes through the long screw hole 10 and is connected to the adjustment section 9, and the nut part of the screw presses against the connecting rod 5.

[0053] By sliding the adjustment section 9 along the long screw hole 10, it is convenient to adjust the total length of the adjustment section 9 and the connecting rod 5. After adjustment, the nut part of the screw is pressed against the connecting rod 5, and the stability is good.

[0054] Furthermore, there are at least two screws and long screw holes 10.

[0055] Rotation of the adjustment section 9 relative to the connecting rod 5 is avoided; at the same time, sliding of the screw relative to the long screw hole 10 during operation is avoided; the stability is improved.

[0056] Furthermore, the driving part 7 is a crank handle, and at least one end of the rotating shaft 2 extends out of the frame 1 and is provided with a crank handle joint.

[0057] When the driving member 7 is not in use, it can be removed, occupying a small space and having a low cost; by inserting the crank into the crank joint at the end of the rotating shaft 2, the rotating shaft 2 can be driven to rotate, and the operation is convenient.

[0058] Furthermore, the slide rails 3 are arranged horizontally, and the two slide rails 3 face each other.

[0059] When the seed guiding pipe rack 6 moves, there is no change in gravitational potential energy, eliminating energy storage components such as springs, saving effort during operation, and having good movement smoothness.

A fluted roller metering device 21 is provided at the lower part of the seed box 20. The seed guiding pipe rack 6 is located below the fluted roller metering device 21. Seed guiding pipes 61 are provided on the seed guiding pipe rack 6. The number of the seed guiding pipes 61 is the same as the number of the outlets of the fluted roller metering device 21. Each seed guiding pipe 61 is connected to an outlet of the fluted roller metering device 21. A hopper 22 is further provided on the inner side wall of the frame 1. The hopper 22 extends to directly below the outlet of the fluted roller metering device 21 and is lower than the seed guiding pipe rack 6.

[0061] Only by operating the driving member 7 can the movement of the seed guiding pipe rack 6 be driven, thereby realizing the separation and combination movement of the seed guiding pipe rack 6 and the fluted roller metering device 21; the operation is convenient; before operation, the seed guiding pipe rack 6 is separated from the fluted roller metering device 21, so that the seeds of the fluted roller metering device 21 fall into the hopper 22, and thus the seeding rate can be weighed and calculated to realize seed calibration.
