Description

Technical Field

[0001] The invention relates to a nettle seeder and belongs to the technical field of seeders. Background Art

[0002] Nettle is a perennial herb native to Eurasia. There are about 50 species in the world, 23 in my country, and they are widely distributed in North China, Northeast China, Northwest China and other places. The plants of the nettle family not only have strong ecological adaptability, but also can grow in cold, arid and barren environments, and can maintain green and high yield for more than 30 years; they also have high nutritional value, with a protein content of up to 35%, rich in mineral elements such as calcium, magnesium, iron, and active substances such as saponins, polyphenols, and flavonoids. However, the weight of 1,000 nettle seeds is only 0.65g, and the germination potential is low, and the sowing emergence rate is low. In order to improve the germination potential and emergence rate of nettle, it is required to sow shallowly, with a soil covering depth of about 5mm. At the same time, according to the growth characteristics of nettle, the surviving plants are required to be distributed in clusters. In order to enhance the soil-topping ability of the seed group, the sowing is done in piles. The growth characteristics require that the surviving plants are distributed in clusters. In order to enhance the soil-topping ability of the seed group, the sowing is done in piles. Then, the existing seed drill generally sows in strips, all in the order of furrowing → planting → covering with soil → pressing. The seed drill has a high seeding height, and the seed discharge port is generally 50-100 cm from the ground. The seeds from the seed discharge port pass through a 100 cm long seed delivery tube and fall into the seed furrow, and then the seeds are distributed in strips. This sowing method cannot meet the sowing requirements of nettles. At the same time, since nettles require very shallow soil covering when sowing, it is difficult to ensure the soil covering depth of nettles with conventional sowing methods.

[0003] In order to ensure the quality of nettle sowing, the nettle seeder follows the following sowing procedure: harrow the ground → press the seed bed with the pressure wheel → the seed meter scatters the seeds in piles with intervals on the seed bed → the subsequent pressure meter compacts the seeds without covering the soil to complete the sowing task. In order to ensure that the seeds falling from the seed meter remain in a pile, the height of the seeds from the seed outlet to the ground is reduced, and the seed tube is removed at the same time. Since the nettle seeds are small and the sowing amount per mu is only 50-100g, it is difficult for the seeds to pile up during sowing. Therefore, they are mixed with fillers during sowing, with a ratio of about 1:20. The fillers are organic materials, such as grass powder, crushed cattle and sheep manure, and the remaining seeds from the threshing (which need to be fried at high temperature to lose the germination rate). After sowing, there is no more soil covering, and the fillers act as the covering soil. These organic fillers are easy to absorb and retain water, and will not cause difficulties in topsoil after the nettle seeds germinate. Summary of the invention

[0004] The invention aims to solve the problem that there is no nettle seeder on the market and provides a nettle seeder.

[0005] The present invention provides a nettle seeder comprising a suspension frame, a seeding box, a first transmission sprocket, a transmission chain, a frame, two roller fixing frames, a second transmission sprocket, a cluster seeding device, two rollers, a ground wheel, a ground wheel bracket, a ground wheel shaft and a seeding shaft; a suspension frame is installed above the front end of the frame, two roller fixing frames are respectively installed below the front and rear ends of the frame, a roller is installed below each of the roller fixing frames, a ground wheel bracket is installed below the frame between the two roller fixing frames, a ground wheel is installed below the ground wheel bracket through the ground wheel shaft, and a first A transmission sprocket, a seeding box is installed on the side of the frame, and the seeding box is located between the ground wheel bracket and the rear roller fixing frame. A cluster seeding device is installed at the bottom of the seeding box, and a seeding shaft is arranged in the cluster seeding device. The cluster seeding device sows seeds by rotating the seeding shaft. A second transmission sprocket is installed outside the seeding shaft, and the first transmission sprocket is connected to the second transmission sprocket by a transmission chain. The rotation of the ground wheel drives the ground wheel shaft to rotate, and then transmits it to the first transmission sprocket, and then transmits it to the second transmission sprocket through the transmission chain, and then transmits it to the seeding shaft, thereby driving the cluster seeding device to seed.

[0006] Preferably, the nettle seeder further comprises a pin, and the roller is fixedly connected to the roller fixing frame via the pin.

During the operation of the seeder, the seed box is filled with seeds, the seed wheel is in the seed box, and the cylindrical holes on the seed wheel are filled with seeds. The seeding shaft drives the seed wheel to rotate, and brushes away excess seeds when passing through the brush.

[0017] Specific implementation method 1: See Figure 1 The nettle seeding machine described in this embodiment includes a suspension frame 1, a seeding box 2, a first transmission sprocket 3, a transmission chain 4, a frame 5, two packer fixing frames 6, a second transmission sprocket 7, a cluster seeding device 8, two packers 9, a ground wheel 11, a ground wheel bracket 12, a ground wheel shaft 13 and a seeding shaft 14; the suspension frame 1 is installed above the front end of the frame 5, two packer fixing frames 6 are installed below the front and rear ends of the frame 5 respectively, a packer 9 is installed below each of the packer fixing frames 6, a ground wheel bracket 12 is installed below the frame 5 between the two packer fixing frames 6, a ground wheel 11 is installed below the ground wheel bracket 12 through a ground wheel shaft 13, and a ground wheel shaft 13 is installed outside the ground wheel shaft 13. A first transmission sprocket 3, a sowing box 2 is installed on the side of the frame 5, and the sowing box 2 is located between the ground wheel bracket 12 and the rear pressure device fixing frame 6, and a cluster seed meter 8 is installed at the bottom of the sowing box 2, and a seeding shaft 14 is arranged in the cluster seed meter 8, and the cluster seed meter 8 sows by rotating the seeding shaft 14, and a second transmission sprocket 7 is installed outside the seeding shaft 14, and the first transmission sprocket 3 and the second transmission sprocket 7 are connected by a transmission chain 4, and the ground wheel 11 rotates to drive the ground wheel shaft 13 to rotate, and then transmits it to the first transmission sprocket 3, and transmits it to the second transmission sprocket 7 through the transmission chain 4, and then transmits it to the seeding shaft 14, thereby driving the cluster seed meter 8 to seed.

[0018] The packer 9 is fixedly connected to the packer fixing frame 6 via a pin 10 .

[0019] The suspension frame 1 is suspended from the tractor, and the seed drill is welded to the frame 5 by the suspension frame 1. The seed box 2 is fixed on the vertical beam of the frame 5, and a pressure frame 6 is welded below the frame 5. The pressure frame 9 is connected to the pressure frame 6 by a pin 10. The ground wheel bracket 12 is welded to the frame 5, and the ground wheel 11 is connected to the ground wheel bracket 12 by a ground wheel shaft 13. The first transmission sprocket 3 is installed on the ground wheel shaft 14. The cluster seeding device 8 is installed at the bottom of the seeding box 2, and the seeding device is rotated by the seeding shaft 14 to sow, and the transmission chain 4 connects the first transmission sprocket 3 with the second transmission sprocket 7.

[0020] The cluster seeding device 8 includes a seeding box 15, a seeding wheel 16 and a brush 17. The seeding shaft 14 is installed in the seeding box 15 filled with seeds, and passes through the seeding wheel 16 to drive the seeding wheel 16 to rotate. The brush 17 is installed at the bottom of the inner side of the seeding box 15, and the upper part is close to the seeding wheel 16. The surface of the seeding wheel 16 is evenly provided with a plurality of cylindrical holes 18. During the operation of the seeder, the seeding box 15 is full of seeds, the seeding wheel 16 is in the seeding box 15, and the cylindrical holes on the seeding wheel 16 are full of seeds. The seeding shaft 14 drives the seeding wheel 16 to rotate, and brushes away excess seeds when passing through the brush 17.

[0021] The seeding wheel 16 is made of plastic material by injection molding, and a cylindrical hole 18 is provided on the cylindrical surface. It is a volumetric seeding device. During the operation of the seeder, when the cylindrical hole 18 on the cluster seeding device 8 is full of seeds, the seeding shaft 14 drives the seeding wheel 16 to rotate, and the excess seeds are brushed off by the brush 17. Because the seeding position of the seeding device is very close to the vertical center line, the seeds will fall on the ground in piles. At the same time, since there is no seed delivery tube, the seeding height is very close to the ground, which ensures that the seeds fall in piles. In addition, the right side of the seeding box 15 is far away from the seeding wheel 16, which reduces the friction resistance of the fine seed particles caused by the small gap between the seeding wheel and the seeding wheel of the conventional seeder, thereby avoiding seed breakage.

[0022] The specific operation process and working principle of the nettle seeding machine described in the present invention are as follows:

[0023] When the nettle seeding machine is working, the tractor moves forward, the front row of rollers 9 flattens the seed bed, and the ground wheel 11 drives the cluster seeding device 8 through the sprocket 3 to drop the seeds on the flattened seed bed. Subsequently, the rear row of rollers 9 compacts the seeds so that they are in close contact with the soil to complete the sowing operation.

[0024] In order to ensure that the seeds dropped by the cluster-shaped seeding device 8 are piled up during sowing, the seeding tube is omitted in this seeding machine, and the seeding device is close to the seed bed.

[0025] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. It can also be a reasonable combination of the features recorded in the above embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
