Technical Field

[0001] The invention relates to the field of coarse grain planting, and in particular to a rotary tillage and fertilization coarse grain seeder. 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 seeder is mounted on the frame through a connecting frame, including a sowing port, a precision sowing disc and a loading hopper. The furrow opener and the rolling roller are used to open furrows and compact the soil to ensure smooth sowing of seeds. The existing device is also equipped with a drip irrigation laying device and a spraying device, which are used for drip irrigation and spraying pesticides respectively.

[0004] The existing seeder has two sets of sowing wheels, and different seeds can be sown by replacing the sowing wheels. However, the planting area of ​​grains is small, the planting area is special, and the yield is low. Therefore, when planting, different grains need to be equipped with different grain seeders to suit the planting of grains of different sizes. In actual use, the cost is high. Summary of the invention

[0005] One purpose of the present invention is to provide a rotary tillage and fertilization grain seeder. The device sows seeds of different sizes by adjusting the inner diameter of the planting channel of the first rotating disk. There is no need to replace the first rotating disk. The operation is simple and convenient, and it does not occupy a large area, which is more conducive to long-term use.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] A rotary tillage and fertilization grain seeding machine comprises a frame, a first rotating disk and a seeding chamber are arranged on the frame; a plurality of planting channels are arranged in the first rotating disk, an adjustment chute is arranged on the side of the planting channel, an adjustment plate is arranged in the adjustment chute, and the adjustment plate can slide in the adjustment chute to adjust the inner diameter of the planting channel; the adjustment plate slides in the adjustment chute, and one end of the adjustment plate moves in the planting channel to adjust the inner diameter of the planting channel. When the first rotating disk is used to sow grain seeds of different sizes, the adjustment plate slides in the adjustment chute, and the inner diameter of the planting channel is adjusted to match the size of the grain seeds to be sown, and the grain seeds are sown through the seed channel located at the lower end and vertical.

[0008] Compared with the existing structure, the present device does not need to replace the first rotating disk or the entire seeder to be suitable for the sowing of grain seeds of different particle sizes, and during the adjustment process, the inner diameter of the planting channel can be adjusted by only sliding the adjustment plate in the adjustment groove.

[0009] Preferably, the side of the first rotating disk is provided with a plurality of action chutes corresponding to the plurality of adjustment chutes, the action chutes are connected to the corresponding adjustment chutes, the side of the adjustment plate is connected to the upper end of the moving rod, the other end of the moving rod passes through the action chutes, and the moving rod is driven to slide in the action chutes, and the adjustment plate is driven to slide in the adjustment chutes, so as to adjust the inner diameter of the planting channel. When adjusting, the operator can directly adjust the moving rod to drive the adjustment plate to slide in the adjustment chutes, which is simple and convenient to operate, without any operation problems, and is more conducive to long-term use.

[0010] At the same time, a nut is threadedly connected to the moving rod, and the nut is used to fix the position of the moving rod in the action chute. When the moving rod needs to be adjusted, the nut is first rotated to separate the nut from the first rotating disk, and then the moving rod can be slid. After the moving rod is moved to the desired position, the nut is rotated to make the nut contact with the first rotating disk, and the nut presses the moving rod against the first rotating disk, thereby fixing the position of the moving rod in the action chute, so as to avoid the moving rod moving during sowing, causing the adjustment plate to move in the adjustment chute, affecting sowing.

[0011] Furthermore, a protective cover is concentrically mounted on the first rotating disk, and the first rotating disk can rotate circumferentially in the protective cover; the protective cover opens at the sowing cavity, and when the sowing cavity moves upward, the upper end of the sowing cavity is located in the opening of the protective cover. The protective cover blocks the openings at the lower ends of the planting channels at other positions of the first rotating disk to prevent seeds from flying out of other planting channels during rotation, and the protective cover enables the planting channel of the first rotating disk to enter the sowing cavity at the upper end of the sowing cavity, that is, when the planting channel is located at the lower end of the first rotating disk and is in a vertical state and is located on the same straight line as the sowing cavity, the seeds in the first rotating disk can enter the sowing cavity through the planting channel.

[0012] Furthermore, when the sowing cavity moves upward, the upper end of the sowing cavity is located in the opening of the protective cover, so that the seeds in the planting channel can better enter the opening at the upper end of the sowing cavity and be sown through the sowing cavity.

[0013] Furthermore, the adjusting member includes a rotating motor and a telescopic assembly, wherein the rotating motor is used to drive the first rotating disk to rotate circumferentially, and the telescopic assembly is used to drive the seeding cavity to move up and down. The adjusting member may include a variety of structures, as long as it can achieve the goal of driving the first rotating disk to rotate and the seeding cavity 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 cavity to move up and down. The rotating structure may be a motor or other structures that can achieve rotation, and the up and down moving may be a telescopic rod or other structures that can achieve up and down movement.

[0014] 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;

[0015] 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 to make the second acting block on the second acting rod move in the groove at the upper end of the second acting rod.

[0016] 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 to drive the seeding cavity to move up and down along the direction of the third acting rod.

[0017] 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.

[0018] 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.

[0019] Preferably, a fixing plate is provided on the frame and is detachably connected to the first rotating disk; the fixing plate is connected to the first rotating disk via a buckle.
