technical field

The invention belongs to the field of sowing agricultural machinery, in particular to a scoop-type pinellia seed metering device for a seeder.

Background technique

With the improvement of modern agricultural mechanized production level, many crops have been mechanized from sowing to harvesting. The root of increasing farmers' income is to increase labor productivity, and agricultural mechanization is the key to improving agricultural labor productivity. Agricultural mechanization not only liberates manpower, but also improves agricultural production efficiency and brings huge economic benefits to farmers. At present, the existing seed metering devices include outer groove wheel seed metering device, centrifugal seed metering device, inner capsule seed metering device, vertical disc seed metering device, air suction seed metering device and horizontal disc seed metering device. Devices, inclined disc seed meters, pneumatic seed meters, etc.

The national annual demand for Pinellia pinellia is about 4.5 million kilograms, and the export volume is about 1.2 million to 2 million kilograms. The contradiction between supply and demand is increasing day by day, so the mechanization of its sowing is imperative. Pinellia sowing is the primary link in the production of Pinellia. Realizing mechanized sowing and continuously improving its mechanization level is the only way to achieve high yield of Pinellia. Most domestic pinellia seeders are improved corn, potato and other seeding equipment similar to pinellia seeds. At present, there is no seeder specially designed for the planting environment requirements and different regions of pinellia. The seeder invented by Shandong Heze Runkang Institute of Chinese Medicinal Materials is also small, simple, and inefficient, and can only achieve single seeding. According to the survey, there is very little supply of pinellia seeders in the market at present, and most of them are designed and manufactured according to orders, and there is no market supply in large quantities.

The existing seed metering device does not have a special spoon structure designed for the characteristics of pinellia seeds, so it is easy to cause waste of pinellia seeds during the seed picking process of the seed metering device, and it will cause damage to the seeds during the seed picking process , affecting the survival rate of pinellia seeds after sowing. The existing seed clearing device does not clear the seeds thoroughly, which easily causes the waste of pinellia seeds during sowing, and the structure is relatively complicated, which also brings troubles to operation and maintenance.

A scoop-type pinellia seed metering device, comprising a seed scoop assembly, a driving wheel 1, a driven wheel 2, a conveyor belt 3, a seed cleaning device, and a guide located on the right side of the conveyor belt 3 and cooperating with the seed scoop assembly. seed tube 4;

The driving wheel 1 is arranged above the driven wheel 2, and the conveyor belt 3 is looped around the outside of the driving wheel 1 and the driven wheel 2. At least one row of seed scoop assemblies is arranged on the conveyor belt 3, and the seed spoon assemblies are arranged at equal intervals; In the embodiment, there are two rows of seed spoon assemblies arranged on the conveyor belt 3, and the distance between the two rows of seed spoon assemblies is the row spacing.

The seed spoon assembly includes a seed spoon 5 and a mounting block 6, the mounting block 6 is fixedly arranged on the upper side of the seed spoon 5, and the mounting block 6 is provided with two mounting holes for installing the seed spoon assembly on the conveyor belt 3, The kind of spoon 5 is an approximately hemispherical structure identical to the similar spherical shape of Pinellia seeds, and the opening direction of the kind of spoon 5 is towards the running direction of the conveyor belt 3;

The shape of kind spoon 5 depends on the shape of pinellia seed, because pinellia seed is similar to spherical shape, so kind of spoon 5 upper end size, height all depend on pinellia seed diameter. There are four kinds of diameter grades of pinellia seeds, which are above 20mm, 15-20mm, 10-15mm, and below 10mm. The first three types can be sown mechanically, and the last type of seeds are too small to be sown, so three corresponding seed spoon structures are designed for the first three diameters. Pinellia seeds of different diameter grades adopt seed spoons 5 of different sizes. In order to ensure that most seeds of the same diameter grade can be applied, it is guaranteed that one seed spoon 5 can only scoop up one seed and ensure that the seeds can be scooped up every time. 0.5 times, specifically: when the diameter grade of pinellia seeds is more than 20mm, the depth of the seed spoon 5 is 16mm, and the maximum diameter of the upper opening is 30mm. When the diameter grade of Pinellia seeds is 15-20 mm in diameter, the depth of the seed spoon 5 is 9 mm, and the maximum diameter of the upper opening is 24 mm. When the diameter grade of pinellia seeds is 10-15 mm in diameter, the depth of the seed spoon 5 is 6 mm, and the maximum diameter of the upper opening is 19 mm.

In order to prevent the seed coat from being damaged by the seed spoon 5, its edge is specially set. The outer edge of the upper end of the seed spoon 5 is provided with a downwardly folded arc-shaped protective sheet 9 , and the arc-shaped protective sheet 9 is arranged higher than the outer edge of the upper end of the seed spoon 5 . Because the pinellia seed is approximately spherical, so the shape of the kind of spoon designed is also approximately hemispherical, and the edge has the circular arc-shaped protective sheet 9 of turning down, can increase the cross-sectional area of kind of spoon 5 like this, in the process of scooping up kind The contact area of the neutralized seeds increases, so that the seed coat can be avoided from being damaged by the seed spoon.

The seed clearing device comprises a first-stage seed clearing device for removing redundant seeds in the seed spoon 5, and a second-stage seed clearing device for removing redundant seeds on the conveyor belt 3 outside the seed spoon 5, and the first-stage seed clearing device It is a vibrating component located in the middle of the inner side of the conveyor belt 3. The vibrating component is a cylindrical roller disc cam mechanism. The cam 10 acts on the conveyor belt 3 as a vibration source, and the motor drives the cam 10 to rotate. Rod 11, the other end of the protruding rod 11 is in contact with the conveyor belt 3. Without changing the eccentricity of the original cam 10, the range of movement of the rod end is adjusted by changing the length of the protruding rod 11, so as to change the conveyor belt 3 The purpose of the amplitude is to convert the rotational motion of the motor into a linear motion, thereby generating horizontal vibration, so that the redundant seeds in the seed spoon will fall due to vibration, and achieve the first level of seed cleaning;

The second-stage seed clearing device is a seed clearing plate 7 positioned at the top of the conveyor belt 3. The seed clearing plate 7 is connected to the frame 8 and is arranged between each row of seed scoop assemblies. At the same time, due to the blocking effect of the seed clearing plate 7, the entrained seeds are dialed back to the seed box to realize the second level of seed clearing;

Because the pinellia seed is similar to a spherical shape, so the seed spoon 5 of design is also similar to a hemispherical shape, so that precision sowing can be realized. The planter can be pulled by a wheeled tractor, and the power is transmitted to the driving wheel 1 through the ground wheel at the front end of the frame 8, thereby driving the seed meter to run, and completing the process of scooping seeds from the seed box and transporting them upward. If more than one seed enters the seeds in the seed spoon 5, when the seed spoon 5 moves to the first-stage seed clearing device, the redundant seeds are removed by the vibration type seed clearing device to realize the first seed clearing; 5. When moving to the highest point, clear the seed for the second time through the fixed seed clearing plate 7, and ensure that there is only one seed in the seed spoon 5 by twice clearing the seed. After the seed spoon 5 moves to the highest point and crosses the driving wheel 1, the seeds fall and fall to the back of the previous seed spoon 5, then move to the lowest point along the seed guide tube 4 along with the seed spoon 5, and finally break away from the seed spoon 5 and fall into the In the seed ditch, complete the seeding operation.

Pinellia seeds are divided into four diameter grades. The first three grades are sown by on-demand sowing, and the last grade is sown by sowing. Different diameter grades have different sowing row spacing and plant spacing. The existing planter spacing adjustment device is changed by replacing the sprocket, but frequent replacement of the sprocket will cause damage to the parts, and it is inconvenient to maintain. The row spacing is adjusted by changing the distance between the seed meters To change the line spacing, the operation is not only troublesome but also difficult to guarantee accuracy.

Pinellia seed diameter grades are different, and the row spacing and plant spacing of sowing are also different. If the diameter is above 20mm, the row spacing is 200mm, and the plant spacing is 70mm; if the diameter is 15-20mm, the row spacing is 180mm, and the plant spacing is 50mm; if the diameter is 10-15mm, the row spacing is 150mm, and the plant spacing is 30mm. So design three kinds of conveyor belts 3 accordingly, the arrangement mode of seed spoon 5 on conveyor belt 3 just arranges according to the required row spacing and plant spacing of three kinds of diameter grades of pinellia seeds, and is all designed into double row.

When the diameter of Pinellia seeds is above 20mm, the distance between the two rows of seed spoon assemblies is 200mm; when the diameter of Pinellia seeds is 15~20mm, the distance between the two rows of seed spoon assemblies 180mm; when the diameter of pinellia seeds is 10-15mm, the distance between the two rows of seed spoon components is 150mm.

The above-mentioned embodiments only illustrate the principles and effects of the present utility model, but are not intended to limit the present utility model. Anyone familiar with this technology can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the utility model should still be covered by the claims of the utility model.
