Technical Field

[0001] The utility model belongs to the technical field of sowing equipment, and particularly relates to a fixed-distance seeder. Background Technique

[0002] In agricultural production, sowing is one of the key links, and the quality of sowing directly affects the growth and yield of crops. There are various existing seeders, but most of them have problems such as complex structure, inconvenient operation, and difficult control of sowing amount. Therefore, how to design a seeder with a simple structure, convenient operation, and adjustable sowing amount has become an urgent problem to be solved. The commonly seen seeders on the market can complete sowing by inserting the seeder into the soil manually and then pulling it out, which is relatively convenient to use. However, since the seeder needs to be lifted frequently, it will cause a great burden on the user during large-area sowing. Content of the Utility Model

[0003] Based on the problems mentioned in the above background technique, the utility model provides a fixed-distance seeder for solving the problem that the existing seeder will cause a great burden on the user during large-area sowing.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A fixed-distance seeder includes a seed storage tank. A first blanking pipe is connected to the bottom of the seed storage tank. The first blanking pipe is connected to a dibbling head. A feeding assembly is arranged in the first blanking pipe. The feeding assembly includes a feeding cylinder. A reserved port is arranged on the feeding cylinder. A material guiding platform in contact with the feeding cylinder is arranged in the first blanking pipe. The feeding cylinder is coaxially connected with a rotating shaft. A wheel frame shaft is fixedly connected to the first blanking pipe. The wheel frame shaft and the rotating shaft are coaxial. Rollers are installed on both the rotating shaft and the wheel frame shaft. The rotating shaft is fixedly connected to the roller. The dibbling head includes a second blanking pipe. A soil-breaking cone piece is fixedly installed on the second blanking pipe. A cover piece is hinged to the soil-breaking cone piece. A torsion spring is connected between the soil-breaking cone piece and the cover piece. A downward-inclined top piece is fixedly connected to the cover piece. When the cover piece is in contact with the soil-breaking cone piece, the top piece is separated from the soil-breaking cone piece. A cloth pipe is connected between the first blanking pipe and the second blanking pipe. A guiding rod is installed on the first blanking pipe. A sliding sleeve is fixedly installed on the second blanking pipe. The sliding sleeve is slidably sleeved on the guiding rod. A return spring is connected between the first blanking pipe and the second blanking pipe. An eccentric wheel is installed on the rotating shaft. A contact platform corresponding to the eccentric wheel is arranged on the second blanking pipe.

[0006] On the basis of the above technical solution, the utility model has further improvements as follows:

[0007] Further, an auxiliary frame is sleeved on the seed storage tank. The auxiliary frame is connected to the rotating shaft and the wheel frame shaft through bearings. A hand-pushing frame is installed on the auxiliary frame. With the help of the hand-pushing frame and the auxiliary frame, it is convenient to push the seeder to move and convenient to use.

[0008] Further, an adjustment groove and a plurality of threaded holes are formed in the eccentric wheel, a connecting piece is arranged on the rotating shaft, and a screw matching the threaded hole is penetrated through the connecting piece. The seeding depth can be adjusted by adjusting the eccentricity of the eccentric wheel.

[0009] Further, when the eccentric wheel does not contact the contact table, the lowest point of the soil-breaking cone piece is higher than the lowest point of the roller. When seeding is not required, the eccentric wheel is adjusted to be coaxial with the rotating shaft and not in contact with the contact table, which can avoid the descent of the second blanking pipe when pulling the seeder and facilitate the handling of the seeder.

[0010] Further, an adjustment column is slidably penetrated in the feeding cylinder, and an adjustment screw for fixing the adjustment column is installed on the feeding cylinder. By changing the position of the adjustment column, the effective capacity of the feeding cylinder can be changed, and the seeding amount can be adjusted.

[0011] The beneficial effects of the present utility model are as follows:

[0012] After the seeds are put into the seed storage tank, the seeder is placed in the planting area and pulled. The rotation of the roller drives the feeding cylinder and the eccentric wheel to rotate. When the feeding cylinder rotates, the seeds in the first blanking pipe can be introduced into the second blanking pipe. When the eccentric wheel rotates, the soil-breaking cone piece and the cover piece can be pressed into the soil. When the soil-breaking cone piece and the cover piece return and rise, the top piece contacts the soil-breaking cone piece under the extrusion of the soil to open the cover piece, so that the seeds fall into the soil, and automatic fixed-distance seeding can be carried out, and at the same time, it will not cause a great burden on the user.

Detailed implementation mode

[0023] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] As Figures 1 to 7As shown in the figure, a fixed-distance seeder includes a seed storage tank 1. A first blanking pipe 11 is connected to the bottom of the seed storage tank 1. The first blanking pipe 11 is connected to a dibbling head. A feeding assembly 5 is arranged in the first blanking pipe 11. The feeding assembly 5 includes a feeding cylinder 51. A reserved opening 511 is formed in the feeding cylinder 51. The reserved opening 511 that rotates with the feeding cylinder 51 can repeatedly obtain the seeds in the first blanking pipe 11 and pour them out. A guiding platform 111 in contact with the feeding cylinder 51 is arranged in the first blanking pipe 11. The feeding cylinder 51 is coaxially connected to a rotating shaft 41. A wheel frame shaft 42 is fixedly connected to the first blanking pipe 11. The wheel frame shaft 42 and the rotating shaft 41 are coaxial. Rollers 22 are installed on both the rotating shaft 41 and the wheel frame shaft 42. The rotating shaft 41 is fixedly connected to the rollers 22. When the rollers 22 rotate, the feeding cylinder 51 can be driven to rotate through the rotating shaft 41. The dibbling head includes a second blanking pipe 12. A soil-breaking cone piece 121 is fixedly installed on the second blanking pipe 12. A cover piece 122 is hinged to the soil-breaking cone piece 121. A torsion spring is connected between the soil-breaking cone piece 121 and the cover piece 122. A downward-inclined top piece 123 is fixedly connected to the cover piece 122. When the cover piece 122 contacts the soil-breaking cone piece 121, the top piece 123 is separated from the soil-breaking cone piece 121. A cloth pipe 13 is connected between the first blanking pipe 11 and the second blanking pipe 12. The cloth pipe 13 has good flexibility and can connect the first blanking pipe 11 and the second blanking pipe 12 without interfering with the movement of the second blanking pipe 12. A guiding rod 14 is installed on the first blanking pipe 11. A sliding sleeve 15 is fixedly installed on the second blanking pipe 12. The sliding sleeve 15 is slidably sleeved on the guiding rod 14. A return spring 16 is connected between the first blanking pipe 11 and the second blanking pipe 12. An eccentric wheel 43 is installed on the rotating shaft 41. A contact platform 124 corresponding to the eccentric wheel 43 is arranged on the second blanking pipe 12.

[0025] Specifically, an auxiliary frame 21 is sleeved on the seed storage tank 1. The auxiliary frame 21 is connected to the rotating shaft 41 and the wheel frame shaft 42 through bearings. A hand-pushing frame 23 is installed on the auxiliary frame 21. With the help of the hand-pushing frame 23 and the auxiliary frame 21, it is convenient to push the seeder to move and convenient to use.

[0026] Specifically, an adjustment groove 431 and a plurality of threaded holes 412 are formed in the eccentric wheel 43. A connecting piece 411 is arranged on the rotating shaft 41. A screw matching the threaded hole 412 is arranged through the connecting piece 411. The seeding depth can be adjusted by adjusting the eccentricity of the eccentric wheel 43.

[0027] Specifically, when the eccentric wheel 43 does not contact the contact platform 124, the lowest point of the soil-breaking cone piece 121 is higher than the lowest point of the roller 22. When seeding is not required, the eccentric wheel 43 is adjusted to be coaxial with the rotating shaft 41 and not in contact with the contact platform 124, which can avoid the second blanking pipe 12 from descending when pulling the seeder and is convenient for carrying the seeder.

[0028] Specifically, an adjusting column 52 is slidably inserted into the feeding cylinder 51, and an adjusting screw for fixing the adjusting column 52 is installed on the feeding cylinder 51. By changing the position of the adjusting column 52, the effective capacity of the feeding cylinder 51 can be changed, and the seeding rate can be adjusted.

[0029] During use, after the seeds are put into the seed storage tank 1, the seeder is placed in the planting land and pulled. The roller 22 rotates to drive the feeding cylinder 51 and the eccentric wheel 43 to rotate. When the feeding cylinder 51 rotates, the seeds in the first blanking pipe 11 can be introduced into the second blanking pipe 12. When the eccentric wheel 43 rotates, the second blanking pipe 12 can be pressed down by squeezing the contact platform 124, so that the soil-breaking cone piece 121 and the cover piece 122 are pressed into the soil. When the soil-breaking cone piece 121 and the cover piece 122 return and rise, the top piece 123 contacts the soil-breaking cone piece 121 under the extrusion of the soil and presses the cover piece 122 into the soil. Then the second blanking pipe 12 rises and resets. When the second blanking pipe 12 rises, the top piece 123 can be attached to the soil-breaking cone piece 121 under the obstruction of the soil to make the cover piece 122 release the seeds. Subsequently, the top piece 123 is separated from the soil-breaking cone piece 121, and the seeds will be buried by the soil to complete sowing.

[0030] The above provides a detailed introduction to a fixed-distance seeder provided by the present utility model. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
