Description

Technical Field

[0001] The utility model relates to the technical field of agricultural breeding, in particular to a conical two-stage seed divider. Background Art

[0002] Nowadays, plot breeding is a scientific breeding method in scientific research bases and actual production, and plot breeding is carried out with plot breeding machines, which greatly improves the breeding efficiency. However, the seed separation device on the common plot breeding sowing equipment has the problem of uneven seed separation during the machine driving and breeding process. The main reason is that the seeds are easily affected by the shaking and tilting of the machine equipment itself, which leads to large differences in the seed separation amount, resulting in poor sowing uniformity and sowing quality, thus affecting the experimental results of field breeding. Especially in terms of seed separation devices, the uniformity of seed separation amount is very important for high-quality field breeding.

[0003] In order to solve the above problems, the inventors designed a quadrangular pyramid seed divider, such as a quadrangular pyramid seed divider in a Chinese patent (application number is 201911300785.3), which includes a quadrangular pyramid with the top of the quadrangular pyramid facing upward; a seed dividing grid plate, the quadrangular pyramid is arranged in the inner cavity of the seed dividing grid plate with the opening facing upward, the quadrangular pyramid divides the inner cavity of the seed dividing grid plate into four sub-cavities, and the bottom ends of the sub-cavities are provided with openings; four seed dividing tubes, the top ends of the seed dividing tubes are respectively connected to the openings of the seed dividing grid plate; two three-way pipes, the top end of each of the three-way pipes is respectively connected to the bottom ends of the two seed dividing pipes arranged diagonally; and two seed dropping tubes, the top ends of the seed dropping tubes are respectively connected to the bottom ends of the three-way pipes, and the bottom ends of the seed dropping tubes are connected to the seed discharger. The beneficial effects of the present invention are: reducing the damage to the uniformity of seeding caused by the tilting and shaking of the vehicle body, improving the uniformity and reliability of seeding, thereby improving the uniformity of seeding, and thus improving the experimental effect of field breeding.

[0004] Although this technical solution can solve the damage to the uniformity of seeding caused by the tilting and shaking of the vehicle body and improve the uniformity and reliability of seeding, this technical solution still cannot evenly distribute the seeds to a certain depth, the seeding effect is not good enough, and there is still a certain unevenness problem.

[0005] In view of this, we propose a conical two-stage seed divider to solve the existing problems. Utility Model Content

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0032] like Figure 1 As shown, a conical two-stage seed divider proposed by the utility model comprises a feeding funnel 1 and a dividing funnel 2. The feeding funnel 1 is installed just above the dividing funnel 2. The lower end of the feeding funnel 1 is rotatably provided with a uniform discharge pipe assembly 3. A conical dividing grid piece 4 is fixedly provided inside the upper end of the dividing funnel 2. A discharge pipe group 5 is fixedly provided at the lower end of the dividing funnel 2. When in use, seeds are dropped from the upper end of the feeding funnel 1, and the seeds fall into the uniform discharge pipe assembly 3 after being blocked inside the feeding funnel 1. After being blocked by the six-dividing grid piece of the uniform discharge pipe assembly 3 and reaching three-level equal division, they are divided into six parts and fall into the dividing funnel 2. After being blocked by the cone 41 and six baffles 42 in the dividing funnel 2, they are further dispersed into six parts for seeding. Then, they are further guided to a group of sowing port pipes through the symmetrical seeding of the discharge pipe group 5, thereby avoiding the problem of insufficient and uniform seeding caused by factors such as equipment tilt, and ensuring strict and uniform seeding.

[0033] like Figure 1 As shown, the upper end of the feeding funnel 1 is in the shape of a funnel and six partitions 6 are evenly and fixedly arranged inside along its own axis; when in use, the six evenly distributed partitions 6 are used to separate the dropped seeds to prevent the seeds from piling up after being dropped, so that after the seeds are dropped in, the seeds will not be excessively gathered on one side due to the tilt of the equipment, thereby ensuring the uniformity of the initial sowing of the feeding funnel 1 as much as possible and preventing the initial sowing from being biased to one side due to seed accumulation; the lower part of the feeding funnel 1 is connected to the uniform discharge pipe assembly 3, and when in use, the seeds are directed to the uniform discharge pipe assembly 3 for the next step of even sowing.

[0034] like Figure 1 and Figure 3 , Figure 6 to Figure 7As shown, the uniform discharge pipe assembly 3 includes a discharge pipe 31, a first six-part grid member 32, a second six-part grid member 33, and a third six-part grid member 34. The first six-part grid member 32 and the second six-part grid member 33 and the third six-part grid member 34 are fixedly arranged at equal intervals inside the discharge pipe 31 and their axes coincide with each other. The radial angles of the first six-part grid member 32 and the second six-part grid member 33 along their own axial projections are staggered by 30°, and the first six-part grid member 32 and the third six-part grid member 34 along their own axial projections coincide with each other. When in use, the first six-part grid member 32 performs the first-level blocking and dispersion on the seeds falling from the discharge funnel 1, and disperses them into six portions. However, the uniformity of the seeds at this time is not enough. It further falls onto the second six-part grid member 33. Because the six grid plates of the first six-part grid member 32 and the six grid plates of the second six-part grid member 33 are staggered by 30°, each of the six portions of seeds dropped in the previous step is further blocked and broken up into six portions by the second six-part grid member 33. The six grid plates of the third six-part grid member 34 and the six grid plates of the second six-part grid member 33 are staggered by 30°, thereby further breaking up the six portions of seeds and redistributing them into six portions. When the seeds fall, they are blocked three times by these three structural members and broken up into six portions. At this time, the number of seeds in each of the six portions is almost the same, thereby further reducing the uneven seed placement caused by equipment vibration, tilt and other factors.

[0035] like Figure 5 As shown, the conical material distribution screen 4 includes a cone 41 with the apex facing upward and six baffles 42. The six baffles 42 are evenly fixed on the outer periphery of the cone 41. The six baffles 42, the cone 41 and the inner wall surface of the distribution funnel 2 enclose six drop openings 7 of the same shape. When in use, the six portions of seeds dropped in the previous step slide down through the guide of the cone 41 to achieve further equal distribution, and then are divided by the guide of the six baffles 42, so that the dropped seeds are evenly divided into six portions and fall from the drop opening 7.

[0036] like Figure 5 and Fig.10 As shown, the six drop openings 7 include a first group of drop openings 71, a second group of drop openings 72, and a third group of drop openings 73 which are symmetrically positioned; when in use, the first group of drop openings 71, the second group of drop openings 72, and the third group of drop openings 73 guide the two symmetrically falling portions of seeds into the discharge pipe group 5 for further equal distribution, thereby ensuring strict equal distribution of the falling mass.

[0037] like Figure 1 to Figure 2 and Figures 8 to 10As shown, the discharge pipe group 5 includes a first discharge pipe assembly 51, a second discharge pipe assembly 52, and a third discharge pipe assembly 53. The upper ports of the first discharge pipe assembly 51, the second discharge pipe assembly 52, and the third discharge pipe assembly 53 are all two feed ports, and the lower ports are all one discharge port. The upper port of the first discharge pipe assembly 51 is connected to the first group of blanking ports 71, the upper port of the second discharge pipe assembly 52 is connected to the second group of blanking ports 72, and the upper port of the third discharge pipe assembly 53 is connected to the third group of blanking ports. 73 are connected; when in use, since each guide tube of the discharge pipe group 5 has two feed ports at the upper end and one discharge port at the lower end, three groups of two portions of seeds falling symmetrically are guided by the first discharge pipe assembly 51, the second discharge pipe assembly 52, and the third discharge pipe assembly 53, and each symmetrical two paths are combined into one group for sowing, so that the uniformity of seed placement is further increased, avoiding the problem of insufficient and uniform seed placement caused by factors such as equipment tilt, and ensuring strict and uniform seed placement.

[0038] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
