DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0037] Example

[0038] Figure 1 A front view of a seed box for a precision seed drill according to one embodiment of the present invention is shown; Figure 2 A left side view of a seed box for a precision seed drill according to one embodiment of the present invention is shown;

[0039] Figure 3 Shows Figure 2 AA direction schematic diagram.

[0040] like Figures 1 to 3 As shown, this embodiment provides a seeding box for a precision seed drill, the seeding box comprising:

[0041] The seeding box body 1 is arranged below the seed box, the inlet of the seeding box body 1 is aligned with the outlet of the seed box, and a slide groove is arranged at the inlet of the seeding box body 1;

[0042] The seed box inserting plate 5 is arranged in the slide groove, and the seed box inserting plate 5 is located between the entrance of the seed box body 1 and the exit of the seed box, and the seed box inserting plate 5 can move back and forth along the slide groove;

[0043] The fine seeding disc 3 is arranged in the seeding box body 1 through the seeding disc shaft 6. The fine seeding disc 3 is arranged near one end of the seed box. The fine seeding disc 3 is sleeved on the seeding disc shaft 6. The fine seeding disc 3 and the seeding disc shaft 6 are clearance-matched. The fine seeding disc 3 is fixedly connected to the seeding disc shaft 6 through the set screws 9.

[0044] The common seeding disc 2 is arranged in the seeding box body 1, the common seeding disc 2 is coaxially arranged with the fine seeding disc 3, the common seeding disc 2 is clearance-matched with the seeding disc shaft 6, the common seeding disc 2 and the fine seeding disc 3 are connected by a limit pin 8, and the limit pin 8 can move on the fine seeding disc 3 and the common seeding disc 2;

[0045] Among them, the seed box shaft is connected to the gearbox of the precision seed drill.

[0046] When the ordinary seed tray 2 and the fine seed tray 3 are connected together by the limit pin 8, the sowing of large seeds, such as wheat, rice, mustard, adzuki beans, etc., is realized. When the limit pin 8 moves to the ordinary seed tray 2, the seed tray shaft 6 only drives the fine seed tray 3 to work, so as to realize the sowing of fine seeds, such as rapeseed, celery, radish, mustard, alfalfa, etc., without repeatedly replacing the seed tray, the operation is simple, the sowing efficiency is improved, and the production cost is reduced.

[0047] It should be noted that since the ordinary seed disk 2 and the fine seed disk 3 are clearance-matched with the seed disk shaft 6, the rotation of the seed disk shaft 6 cannot directly drive the ordinary seed disk 2 and the fine seed disk 3 to rotate, and then the fine seed disk 3 and the seed disk shaft 6 are fixedly connected by the set screws 9, so that the rotation of the seed disk shaft 6 drives the rotation of the fine seed disk 3, and the fine seed disk 3 and the ordinary seed disk 2 are connected again by the limit pin 8, which further drives the ordinary seed disk 2 to rotate. When sowing fine seeds, the positioning pin is moved to the side of the ordinary seed disk 2 to disengage the fine seed disk 3, then only the fine seed disk 3 rotates, and the ordinary seed disk 2 is clearance-matched with the seed disk shaft 6, so the seed disk shaft 6 cannot drive the ordinary seed disk 2 to rotate together.

[0048] Furthermore, the seed box is provided with a plurality of outlets, each outlet corresponding to a seed box, and the seed box plug plate 5 between the seed box and the seed box can move back and forth between the seed box and the seed box to adjust the size of the opening between the seed box and the seed box, and then adjust and control the size of the opening according to the required sowing amount.

[0049] Furthermore, the seed box also includes:

[0050] The flow adjustment seat 4 is arranged in the seeding box body 1 at one end away from the fine seeding disc 3 through the adjustment shaft 7;

[0051] A flow adjustment bushing 10, one end of which is connected to the flow adjustment seat 4 via a bolt 11, and the other end of which is connected to the flow adjustment seat 4 and the adjustment shaft 7 via a fastening screw 13;

[0052] A spring 12 is provided between the flow adjustment bushing 10 and the flow adjustment seat 4 .

[0053] The flow regulating bushing 10 is made of cast aluminum.

[0054] The flow regulating bushing 10 made of cast aluminum is not only light in weight but also has good wear resistance, thereby increasing the service life of the seed box.

[0055] The flow adjustment seat 4 is equipped with a flow adjustment bushing 10 made of cast aluminum. The flow adjustment seat 4 and the flow adjustment bushing 10 are connected to the adjustment shaft 7 through the fastening screws 13, that is, the fastening screws 13 fasten the flow adjustment seat 4 to the adjustment shaft 7. Through the adjustment handle at the outer end of the flow adjustment seat 4, since the adjustment handle and the adjustment shaft 7 are fastened together, the adjustment shaft 7 is turned to drive the rotation of the flow adjustment seat 4, change the distance between the ordinary seeding disc 2 and the fine seeding disc 3 and the flow adjustment seat 4, and then control the size of the flow of seeds flowing out of the seeding box to meet different seeding requirements. During sowing, there are multiple seeding boxes under the seed box, and the flow adjustment seat 4 is installed on the adjustment shaft 7. The adjustment shaft 7 is a through shaft. When the adjustment handle is used to turn the adjustment shaft 7, all the flow adjustment seats 4 of the entire machine rotate together and are in the same position, ensuring that the openings of the flow adjustment seats 4 of each seeding box are consistent, and the flow of each seeding box is consistent. The adjustment is very simple and convenient.

[0056] Furthermore, the provision of the spring 12 can play a role in shock absorption and buffering, thereby preventing the flow adjustment bushing 10 and the flow adjustment seat 4 from colliding, thereby increasing the service life of the flow adjustment bushing 10 and the flow adjustment seat 4.

[0057] It should be noted that the seed box of this embodiment is made of high-strength plastic as a whole, has a simple structure, is easy to manufacture, has a small size, and is light in weight, which reduces production costs and improves the economy of the seed box.

[0058] Furthermore, the seed box also includes:

[0059] The gap retaining ring is arranged between the ordinary seeding disc 2 and the fine seeding disc 3.

[0060] There is a gap retaining ring between the ordinary seeding disc 2 and the fine seeding disc 3. The gap washer 15 is made of elastic material to ensure that the two seeding discs can be in flexible contact, reduce the friction between the two seeding discs, and increase the service life of the two seeding discs.

[0061] Furthermore, a positioning wedge 16 is provided on the seed box body 1 , and the seed box body 1 is connected to the seed box via the positioning wedge 16 .

[0062] Multiple openings are provided on both sides of the outlet of the seed box, so as to avoid using screws. Only the positioning wedge 16 on the seed box body 1 is inserted into the opening of the seed box to realize the connection between the seed box and the seed box, which is simple to operate and has a good positioning effect.

[0063] Furthermore, the seed box also includes:

[0064] The seed box baffle 14 is arranged outside the seed box body 1. The seed box baffle 14 is located at an end away from the seed box. The seed box baffle 14 is arranged close to the fine seeding disc 3 and the common seeding disc 2.

[0065] When the fine seeding disk 3 works alone, or the fine seeding disk 3 and the ordinary seeding disk 2 work at the same time, the setting of the seed box baffle 14 can ensure that the seeds to be sown are all in the fine seeding disk 3 and the ordinary seeding disk 2, and the excess seeds in the fine seeding disk 3 and the ordinary seeding disk 2 are scraped into the seed box body 1 to ensure the uniformity of sowing.

[0066] Furthermore, the common seeding disc 2 comprises a first disc 21 and a second disc 22 , and transmission grooves are provided on the outer circumferences of the first disc 21 and the second disc 22 .

[0067] It should be noted that the first plate 21 and the second plate 22 are integrally formed, wherein the transmission groove is used to place seeds to be sown, and the seed box baffle 14 is used to scrape off excess seeds in the transmission groove.

[0068] Furthermore, the transmission grooves on the first plate 21 and the transmission grooves on the second plate 22 are arranged alternately.

[0069] The staggered transmission grooves can ensure the continuity of sowing and the accuracy of seeding amount.

[0070] When the common seeding disc 2 and the fine seeding disc are working at the same time, that is, when large-grain seeds are sown, the staggered transmission grooves can ensure the continuity of seed sowing.

[0071] Similarly, two rows of transmission grooves are evenly arranged on the outer circumference of the fine seeding disc, and the two rows of transmission grooves are staggered.

[0072] Specifically, the seeds to be sown are poured into the seed box and enter the seed box body 1 through the outlet of the seed box. When sowing large seeds (such as wheat, rice, mustard, adzuki beans, etc.), the fine seed disc 3 and the ordinary seed disc 2 rotate at the same time, and the staggered transmission grooves realize the continuity of sowing large seeds. When sowing fine seeds (such as rapeseed, celery, radish, mustard, alfalfa, etc.), the ordinary seed disc 2 is separated from the fine seed disc 3, and only the fine seed disc 3 works. There is no need to repeatedly replace the seed disc, and the operation is simple.
