Description

Technical Field

[0001] The invention relates to the field of coarse grain planting, and in particular to an adjustable coarse grain seeding device. Background Art

[0002] Coarse grains usually refer to grain and bean crops other than the five major crops of rice, wheat, corn, soybean and other crops. They mainly include: sorghum, millet, buckwheat (sweet buckwheat, bitter buckwheat), oats (naked oats), barley, foxtail millet, millet, sorghum, amaranth, kidney beans (kidney beans), mung beans, adzuki beans (red beans, red beans), broad beans, peas, cowpeas, lentils (lentils), black beans, etc. They are characterized by short growth period, small planting area, special planting areas, low yields, and generally contain rich nutrients.

[0003] The seeding device is specially designed for a certain type or category of crops. It can realize different sowing methods such as spot sowing and row sowing. It can complete spot sowing, row sowing, furrowing, sowing, covering soil, and array pressing at one time. The existing seeder has two sets of sowing wheels, and different seeds can be sown by replacing the sowing wheels. However, the existing sowing wheels are troublesome to replace, and require multiple workers to operate, which is time-consuming and laborious. Summary of the invention

[0004] One object of the present invention is to provide an adjustable grain seeding device, in which a fixed plate is detachably connected to a first rotating disk. When in use, different seeds can be sown by replacing the first rotating disk. There is no need to replace the seeding device, and the first rotating disk can be directly replaced. The operation is simple and convenient, and it does not occupy a large area, which is more conducive to long-term use.

[0005] This purpose is achieved by adopting the following technical solutions:

[0006] An adjustable grain seeding device comprises a first rotating disk and a seeding cavity, wherein the first rotating disk and the seeding cavity are detachably connected to the seeding device, and the seeding device can be a larger vehicle-type seeding device or a hand-push seeding device. The first rotating disk and the seeding cavity are detachably connected to a fixed plate.

[0007] Specifically, a seed storage cavity and several planting channels are provided in the first rotating disk, and the seeds in the first rotating disk are placed in the seed storage cavity. When one end of the sowing cavity is located in the planting channel, one end of the sowing cavity hinges the seed storage cavity at the planting channel with a baffle to lift it upward, and the baffle rotates. One end of the sowing cavity has an opening. Therefore, when one end of the sowing cavity is located in the planting channel, one end of the sowing cavity lifts the baffle and inserts it into the seed storage cavity. The seeds planted in the seed storage cavity enter the sowing cavity through the opening at one end of the sowing cavity, and are inserted into the soil during the downward movement of the sowing cavity, so that the seeds enter the soil.

[0008] An adjusting member is provided between the first rotating disk and the sowing chamber, which can rotate the first rotating disk and drive one end of the sowing chamber to move up and down and insert into several planting channels in sequence during the rotation of the first rotating disk, so that the sowing chamber inserts the seeds in the seed storage chamber into the soil.

[0009] The fixing plate is fixedly connected to other structures, such as wheels. When the first rotating disk needs to be replaced to sow grains of other sizes, the first rotating disk, the sowing cavity and the adjusting member of the device are separated from the fixing plate, and the first rotating disk is replaced again to match seeds of different sizes.

[0010] Compared with the existing structure, this structure only needs to replace the first rotating disk, the operation is simple and convenient, and no extra area needs to be occupied. It is more conducive to the planting and use of grains and can effectively save costs.

[0011] Furthermore, the adjusting member may include a variety of structures, as long as it can drive the first rotating disk to rotate and the seeding chamber to move up and down. The adjusting member may be a combination of a rotating structure and an up and down moving structure, wherein the rotating structure drives the first rotating disk to rotate, and the up and down moving structure drives the seeding chamber to move up and down. The rotating structure may be a motor or other structure that can achieve rotation, and the up and down movement may be a telescopic rod or other structure that can achieve up and down movement.

[0012] In order to further reduce the weight and simplify the structure, the inventor has preferably selected an adjusting member. Specifically, the adjusting member includes a first action rod, a second action rod, a third action rod and a second rotating disk; a plurality of first action blocks are arranged on the first rotating disk, a second action block is detachably connected to the fixed plate, and both ends of the second action rod have grooves; the second action block is located in the groove at the upper end of the second action rod; a plurality of first action blocks correspond to a plurality of planting channels one by one. The sowing chamber is mounted on the third action rod, and the third action rod moves the sowing chamber in a vertical direction; the first action rod is connected to the sowing chamber by a first connecting block, the first action rod is connected to the second action rod by a second connecting block, the second action rod is connected to the second rotating disk by a third connecting block, and the second rotating disk is concentrically arranged with the first rotating disk;

[0013] When in use, the second rotating disk rotates, and the third connecting block is driven to rotate together during the rotation of the second rotating disk. During the rotation of the third connecting block, the second acting rod is acted on, so that the second acting block on the second acting rod moves in the groove at the upper end of the second acting rod.

[0014] The second rotating disk drives the third connecting block to rotate. Under the action of the third connecting block and the second acting block, the groove at the lower end of the second acting rod is inserted into several first acting blocks in sequence to drive the first rotating disk to rotate; at the same time, the second acting rod acts on the first acting rod, driving the sowing cavity to be inserted into several planting channels in sequence along the direction of the third acting rod.

[0015] Therefore, under the rotation of the second rotating disk, the structure can simultaneously make the first rotating disk and the sowing cavity be inserted into a plurality of planting channels in sequence along the direction of the third action rod, thereby simplifying the operation and structure and being more conducive to long-term use.

[0016] Preferably, a through hole is provided at the center of the first rotating disk, and a second rotating disk is provided in the through hole. The second rotating disk is connected to the first rotating disk and can rotate circumferentially on the first rotating disk.

[0017] In addition, the third action rod is connected to the lower end of the fixing plate. The sowing cavity is detachably connected to the third action rod by sliding into the third action rod from top to bottom.

[0018] At the same time, a connecting plate is provided on the fixed plate, a sliding groove is provided on the connecting plate, the sliding groove opens at the upper end of the connecting plate, and a sliding block corresponding to the sliding groove is provided on the first rotating plate. The sliding block slides into the sliding groove from top to bottom to make the fixed plate and the first rotating plate detachably connected.

[0019] The fixing plate is provided with a connecting groove, and the second acting block is detachably connected to the connecting groove.

[0020] Preferably, eight planting channels are arranged in the first rotating disk, and when the first rotating disk rotates so that the planting channels reach the vertical direction in sequence, one end of the sowing cavity is inserted into the planting channel. Eight planting channels are arranged in the first rotating disk, and when the first rotating disk rotates, each planting channel can be better positioned at the vertical direction below for sowing, and the sowing positions are spaced at an appropriate distance.

[0021] During use, when the first rotating disk needs to be replaced, the second action block is separated from the connecting groove, and the first rotating disk and the seeding chamber are moved upward. During the upward movement of the seeding chamber, the third action rod is disengaged, and during the upward movement of the first rotating disk, the slider is disengaged from the slide groove, thereby realizing the replacement of the first rotating disk. The operation is simple and convenient.

[0022] When one end of the sowing cavity is located outside the planting channel, the other end of the sowing cavity is inserted into the soil, and the depth of the sowing cavity inserted into the soil is greater than 5 cm, thereby improving the planting efficiency.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] The present invention discloses an adjustable grain seeding device, which can quickly and conveniently replace the first rotating disk, and grain seeds of different sizes can be sown by replacing the first rotating disk, so as to have a wider range of uses. Moreover, the operation during replacement is simple and convenient, and there is no complicated operation, and the replacement can be realized by directly extracting upward.

[0025] When the device is adjusted for grains of different sizes, there is no need to replace the entire seeding device structure, only the first rotating disk in the seeding device needs to be replaced, and the first rotating disk occupies a small volume, so it is more suitable for sowing grains of different sizes. There is no need to prepare multiple seeding device structures, and it can be better suitable for sowing grains.

[0026] On the other hand, when replacing the first rotating disk, the operation is simple and there is no complicated operation, which is more conducive to long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example 3

[0056] On the basis of the above embodiment, a through hole is provided at the center of the first rotating disk 1 , and a second rotating disk 17 is provided in the through hole. The second rotating disk 17 is connected to the first rotating disk 1 and can rotate circumferentially on the first rotating disk 1 .

[0057] like Figure 7 As shown, the fixing plate 3 is provided with a connecting plate 4, and the connecting plate 4 is provided with a sliding groove 41, and the sliding groove 41 opens at the upper end of the connecting plate 4. Figure 8 As shown, a slider 13 corresponding to the slide groove 41 is provided on the first rotating disk 1 , and the slider 13 slides into the slide groove 41 from top to bottom so that the fixing plate 3 is detachably connected to the first rotating disk 1 .
