Further, the cylindrical support ring 505 has multiple alternative specifications.

Further, there are two ratchet brackets 10 and two anti-falling devices, which are symmetrically distributed left and right.

When using the quantitative distribution device, the upper end of the quantitative distribution device can be connected with a hopper, and the lower end of the quantitative distribution device can be connected with a material guide device such as a guide pipe or a guide rod to perform quantitative distribution of materials.

As shown in Figure 1---Figure 6, the quantitative distribution device includes a central shaft 13, and the middle part of the shaft is connected with two ratchet brackets 10 with clearance fit, and the axial positioning is carried out by the positioning ring 12, and it is realized by the set screw 11. The circumferential and axial positioning of the positioning ring 12 can prevent the seed metering device 5 from sliding axially. body 508, in order to ensure the tightness of the cup groove, the two sides are respectively installed with 8 circular side walls 501 evenly distributed through holes for eight guide rods 503 to pass through, and a circular side wall 501 with two through holes in the vertical direction. The sealing ring 4 is welded on the outer shell 6. During the installation process, the ratchet bracket 10 is closely attached to the circular side wall 501. In order to realize the adjustable capacity of the seed metering device 5, a cylindrical support ring 505 is used at the bottom of the cup groove 502. Support the concave cup 504 and connect it to the frame body 508 with the adjusting bolt 507. When adjusting the volume of the cup groove, the cylindrical support ring 505 can be replaced to meet the requirements of different capacities. , the outside of the outer shell 6 is threadedly connected to the two ends of the outer shell 6 by the nest 902 and the central shaft 13, and the outside of the nest 902 is respectively connected to the rotating handle 9 through two bearings 901. In order to prevent the rotating handle 9 from falling off, the A baffle 904 is set at the end of the nesting 902, and the baffle is fixedly connected with fastening screws 905. In order to ensure the convenience of installation, the end of the rotating handle 9 is finally screwed to the handle end cover 903, and each end of the handle 9 is hinged with two The ratchet 8 is used to drive the ratchet bracket 10 to rotate, and each end of the upper part of the handle 9 is designed with a long rod-shaped toothed bar to drive the swing of the dial 3, so as to ensure the normal falling of the material without bridging; Figure 2 briefly introduces that the components are assembled in layers from both sides to the middle to form a material quantitative distribution device, and Figure 4 and Figure 6 are schematic diagrams of layer-by-layer assembly of the seed metering device and the rotating handle.

As shown in Figure 7---Figure 10, the inside of the cup groove 502 contains a concave cup 504 and a cylindrical support ring 505, which are screwed together with the frame body 508 through the adjusting bolt 507, in order to ensure the sealing of the cup groove 502 To ensure that the material does not spill during the movement, a circular side wall 501 made of a thin plate and a circumferential sealing ring 4 are externally connected. Because the entire seeding device 5 is in a state of circular motion, the sealing ring 4 is welded to the outer shell 6. And there is a small gap with the outer edge of the seed metering device 5 to ensure that the normal rotation of the seed metering device 5 is not affected when the material is not spilled, and the guide rod 503 can just pass through the eight through holes on the side wall, so that the side wall 501 follows and rotates together. In order to realize the adjustable capacity of the seed metering device 5, a cylindrical support ring 505 is used to support the concave cup 504 at the bottom of the cup groove 502, and the adjusting bolt 507 is connected to the frame body 508. When adjusting the volume of the cup groove, the column can be replaced. The cylindrical supporting ring 505 meets the requirements of different capacities, and the spring 506 ensures that the outer edge of the seed metering device 5 can always be in proper contact with the sealing ring 4 under different cylindrical supporting rings.

When adjusting the material of different seeding rates, the columnar support ring 505 can be exchanged into support rings of different lengths, and the adjustment screw 507 can always pass through the concave leather cup 504, the columnar support ring 505, the bottom of the cup groove 502 and the The frame body 508 is connected in one body. When the length of the cylindrical support ring 505 is longer, it indicates that the capacity inside the cup groove 502 is smaller, and then the space inside the seeding device 5 is determined by exchanging the cylindrical support ring 505, so as to realize Seed rate control.

There are eight evenly distributed through holes on the annular side wall 501, and the guide rod 503 can just pass through these through holes, so that when the seed metering device 5 rotates, the annular side wall 501 can follow the rotation in real time, so as to ensure good rowing. The overall sealing of the seeding device does not affect the normal rotation of the seeding device.

The seed metering device 5 adopts an 8-point design as a whole. For a good seed metering device, the side walls of the left and right seed metering devices are tightly connected with hexagonal screws 26 between each frame body 508 gap of the seed metering device.

As shown in FIG. 11 , use the set screw 11 to position the positioning ring 12 in both the circumferential direction and the axial direction, so as to avoid the axial sliding of the seed metering device 5 on the central shaft 13 .

As shown in Figure 12 and Figure 13, the two springs 2 are all hooked on the dial 3 in series, and the other ends of the return springs 2 are respectively connected in the U-shaped grooves designed on the inner surface of the outer shell 6, when the dial 3. When it deviates from the center position during the rotation, it can automatically return to the center position under the action of the return spring 2 to ensure the normal operation of the next toggle action; while the dial 3 and the outer shell 6 are connected by a collar screw Its center is fixed on the outer casing 6 to ensure that it will not deviate from the set position during the rotation.

As shown in Figure 14 and Figure 15, the non-return claw 7 is connected to the outer casing 6 by screws at the set position, and the connecting screw is divided into two sections with different diameters, and the non-return claw 7 is placed in the gap between the smaller diameter ends The cooperation not only ensures that the non-return claw 7 will not slide axially, but also ensures the normal operation of the non-return claw 7 .

As shown in Figure 16, the ratchet 8 is hinged to the rotating handle 9, and the other end passes through the outer shell 6 for follow-up work. As can be seen from Figure 17, when the ratchet 8 passes through the outer shell 6, in order to ensure The work of the pawl 8 driving the ratchet meets the reasonable working conditions of the design every time, and the outer shell 6 only has a 45-degree annular through hole to give it a movable space. When the pawl rotates 45 degrees each time, the device completes a For the process action of transporting materials, correspondingly when the handle 9 rotates 45 degrees, the ratchet 8 rotates to the initial position of the next process action. This design guarantees the realization of the normal operation of the machine.

As shown in Figure 18, it is a schematic diagram of the action when the handle 9 is turned to three different working positions. When the handle 9 is turned, the long-rod toothed bar on the end surface can realize the mutual meshing between one end of the dial 3 and the tooth shape. The form rotates with the rotating handle 9. When it is in the center position, the dial 3 meshes with the tooth shape. When the rotating handle 9 rotates from the central position to the position of the rotation process, the dial 3 will follow it to rotate and fall downward in the hopper. Dredge the materials (such as seeds, fertilizers, etc.) to avoid the bridging of materials, and when the handle 9 is further rotated to the aforementioned 45-degree work end position, the dial 3 will break away from the meshing relationship with the tooth shape. Under the action of the elastic force of the return spring 2, the dial 3 returns to the center position. When the handle 9 turns 45 degrees to the initial position, the dial 3 will continue to engage with the tooth shape, so as to continue the next work, and so on. , so that there will be no bridging phenomenon in the material, so as to ensure the smooth flow of the material.

As shown in Figure 19, the ratchet wheel bracket 10 adopts a ratchet design, and the ratchet bracket 10 and the seeding device 5 are fixed as a whole through screw connection. When the handle rotates, the ratchet 8 drives the ratchet bracket 10 to rotate. When the claw 8 rotates 45 degrees counterclockwise, the ratchet bracket 10 rotates 45 degrees accordingly. So far, the machine has completed a material transportation action. One rotation operation, when the ratchet 8 rotates due to the rotation of the handle, the ratchet 8 rotates clockwise along the surface of the ratchet bracket 10, in order to avoid the phenomenon of air leakage caused by the rotation of the ratchet bracket 10 and the seeding device 5, The non-return claw 7 on one side of the ratchet bracket 10 blocks the ratchet bracket 10 to prevent the ratchet bracket 10 from rotating, while the ratchet 8 enters the next working position along the outer surface of the ratchet wheel bracket to ensure smooth quantitative distribution of materials conduct.

As shown in Figure 20 and Figure 21, the anti-falling device (guide rod 503, guide groove 27) plays a considerable role in material discharge. When the materials (such as seeds, fertilizers, etc.) smoothly pass through the through hole and fall to the cup groove 502, when the cup groove 502 holds an appropriate amount of materials, the seed metering device 5 rotates with the rotation of the rotating handle 9, and the frame body 508, when the seeding device 5 rotates to the position where the material is not contained, it is closely combined with the two through holes in the vertical direction of the sealing ring 4 to ensure that the material does not fall at this time; when the rotating handle rotates 45 degrees, the seeding device 5 Also rotate 45 degrees, when the seeding device 5 completed two working procedures, the cup groove 502 reached the horizontal position, at this position, the guide rod 503 began to contact the guide groove 27 welded on the outer shell 6, when the seeding device 5 continued to When rotating along with the rotation of the rotating handle, since the guide groove 27 presents a restrained design on the outer shell 6, the guide rod 503 slides along the inner wall of the guide groove 27, so that the cup groove 502 has a tendency to shrink inwardly, and the spring 506 is good. This kind of phenomenon is solved, and the cup groove 502 is guaranteed to shrink inward under the interaction force between the guide rod 503 and the guide groove 27. When the seed metering device 5 rotates two working positions again, the guide rod 503 advances to the end of the guide groove 27, The cup groove 502 rotates to the vertical position. When the guide rod 503 falls off from the end of the guide groove 27, the cup groove 502 has a vertical downward sudden impact under the elastic force of the spring 506. This force realizes the material (such as Seeds, fertilizers, etc.) completely fall to avoid the stagnation of materials.

Under the swing of the dial 3, the materials (such as seeds, fertilizers, etc.) evenly fall into each cup groove 502 of the seed metering device 5 through the feeding port. The device 5 and the ratchet bracket 10 are connected together by screws, the central shaft 13 is screwed to the nest 902, and the rotating handle 9 is connected to the nest 902 by a bearing in order to be able to flexibly rotate. The handle rotation behavior is invalid. When the handle 9 is rotated, the seed metering device 5 rotates a working stroke under the drive of the ratchet 8, and because the bracket 10 adopts a ratchet design, the size of a working stroke is better controlled, and the ratchet The pawl 8 and the rotating handle 9 are hinged. When the user rotates the handle, the pawl 8 can rotate well without affecting the rotation stroke of the seeding device 5. The friction on the surface of the type bracket 10 drives the seeding device 5 to rotate; the long rod type rack can drive the dial 3 to swing back and forth when the handle 9 is rotated, thereby avoiding the phenomenon of material bridging.

Generally speaking, during use, the device is placed vertically on the soil surface, and when the material (such as seeds, fertilizers, etc.) falls evenly into each of the left and right cup grooves 502 under the back and forth movement of the dial 3, the workers The rotating handle 9 can be operated to make the seeding device 5 rotate with the ratchet bracket 10 under the torque of the ratchet 8. When it rotates to a certain angle, the ratchet 8 is limited by the angle of action in the outer shell 6, so that The rotation angle of the seeding device 5 and the ratchet bracket 10 is limited each time to ensure the accuracy of seeding and sowing, and when the rotating handle 9 is continued to rotate, due to the hinged characteristics of the non-return pawl 7 and the ratchet 8 on the handle 9, The seed metering device 5 and the ratchet bracket 10 will not turn around, so as to avoid seed leakage; and when the seed metering device 5 and the ratchet bracket 10 move to a certain angle with the rotation of the handle 9, the cup groove 502 is welded externally. The anti-falling device composed of the guide rod 502 and the guide groove 27 welded on the outer shell 6 operates to ensure that the material (such as seeds, fertilizers, etc.) will not fall when it enters the next device from the material quantitative distribution device ; and in this device, since the seeds and the fertilizer are in two different material distribution devices, the synchronous broadcasting of the seeds and the fertilizer can be realized, and the mutual non-contact of the seeds and the fertilizer can also be ensured to improve the efficiency; and the independent distribution of the two hoppers It can ensure the random disassembly performance of the hopper and is easy to operate.

To sum up, the material quantitative distribution device provided by the embodiment of the present invention has a simple structure, convenient operation, and ingenious conception, and can distribute materials quantitatively, saving manpower and time.

The above disclosures are only a few specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes conceivable by those skilled in the art shall fall within the protection scope of the present invention.
