Description

Technical Field

[0001] The utility model relates to the technical field of crop sowing, in particular to an improved rotary seeder. Background Art

[0002] Rice is the basic staple food crop in my country, and the common rice planting method is seedling transplanting. Dryland rice is a new rice cultivation technology developed in recent years. Its main technical links include cultivating drought-resistant rice varieties, and then using a seeder to sow rice seeds in rows into the soil on the dry land after raking and leveling. In the prior art, when using a seeder for sowing, if two people are required to draw a straight line in the field by measuring and adding a pull line, and then push the seeder along the pull line. Sowing cannot be completed alone. This sowing method is inefficient and wastes manpower; or it relies on "eyesight" to estimate the row spacing for sowing. This method has extremely high requirements for the sower, especially when the soil is large and the soil is dry and difficult to judge, it is easy to cause uneven row spacing and affect the accuracy of sowing. Therefore, there is an urgent need for a sowing device that can easily control the sowing row spacing and improve the sowing quality and efficiency. Utility Model Content

[0003] The utility model aims to provide an improved roller seeding device, which can ensure equal seeding row spacing, improve seeding quality and efficiency, save manpower, facilitate adjustment of seeding row spacing, and adjust the depth of dug grooves.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An improved seed roller comprises a rectangular bracket, wherein a push rod is arranged on the upper end of the rectangular bracket tilted upward from the bottom, a seeding disc is rotatably connected inside the rectangular bracket, limiting grooves are arranged at both left and right ends of the rectangular bracket, a first threaded rod arranged horizontally is rotatably connected inside each limiting groove, a second threaded rod arranged in a thread opposite to the first threaded rod is arranged at the free end of each first threaded rod, a first threaded sleeve is threadedly connected to the outer side of each first threaded rod, a second threaded sleeve is threadedly connected to the outer side of each second threaded rod, a first connecting rod is rotatably connected to the outer side of each first threaded sleeve, an end of each first connecting rod away from the corresponding first threaded sleeve is rotatably connected to the limiting sleeve, and a second connecting rod rotatably connected to the limiting sleeve is rotatably connected to the outer side of the second threaded sleeve;

The outer side of each limit sleeve is provided with a fixing bolt that is threadedly rotated and slidably connected to the corresponding fixing hole, and the interior of the rectangular bracket is provided with a driving device for driving the second threaded rod to rotate.

[0007] By adopting the above technical solution, when sowing, the seeding plate is pushed to rotate forward, and the limit rods at the left and right ends of the rectangular bracket can dig grooves in the field. After completing the sowing of a row, the limit rod at one end is extended into the groove based on the dug groove, and then the seeding plate is pushed forward, and the limit rod at the other end digs another groove, and then the limit rod at one end is extended into the groove based on the dug groove, and the seeding plate is pushed forward for sowing, thereby ensuring that the row spacing between sowing is equal; when it is necessary to adjust the row spacing between seeds, the second threaded rod is driven to rotate by the driving device, and the second threaded rod drives the first threaded rod to rotate, and the first threaded rod drives the second threaded rod to rotate. The threaded rod drives the first threaded sleeve to slide in the corresponding limit groove, drives the corresponding first connecting rod to rotate relative to the first threaded sleeve, and the second threaded rod rotates to drive the second threaded sleeve to slide in the corresponding limit groove, drives the second connecting rod to rotate relative to the second threaded sleeve, thereby driving the limit sleeve to move in the direction away from or close to the rectangular bracket, and the limit sleeve drives the corresponding limit rod to move in the direction of approaching or moving away from each other, thereby changing the row spacing between seeds, and the depth of the dug groove can be adjusted by loosening the fixing bolt and pulling the limit rod to slide relative to the limit sleeve, and then the fixing bolt is screwed into the corresponding fixing mouth to fix the limit rod.

[0008] The utility model is further configured as follows: a cone block is arranged at the lower end of each limiting rod.

[0009] The utility model is further configured as follows: the driving device includes a first pulley arranged at an end of each second threaded rod away from the corresponding first threaded rod and extending into the interior of the rectangular bracket, a rotating shaft rotatably connected to the first pulley inside the rectangular bracket, two second pulleys arranged at equal intervals on the outer side of the rotating shaft near one end of the first pulley, and a transmission belt for transmission arranged between each first pulley and the corresponding first pulley.

[0010] The utility model is further configured as follows: a knob is provided at the free end of the rotating shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] First, it is convenient to fix the row spacing of sowing, and at the same time, it is convenient to adjust the row spacing of sowing, thereby improving the sowing quality and efficiency, saving manpower, by rotating the first pulley, the first pulley drives the second pulley to rotate through the transmission belt, the second pulley drives the second threaded rod to rotate, the second threaded rod drives the first threaded rod to rotate, the first threaded rod rotates to drive the first threaded sleeve to slide in the limiting groove, the second threaded rod rotates to drive the second threaded sleeve to slide in the limiting groove, the first threaded sleeve and the second threaded sleeve move in a direction close to or away from each other, the first connecting rod and the second connecting rod drive the limiting sleeve to move in a direction close to or away from the rectangular bracket, so that the limiting rod moves in a direction close to or away from the sowing disk, and the sowing row spacing is changed;

[0013] Secondly, the depth of the trench can be easily changed by unscrewing the fixing bolt from the fixing mouth, then pulling the limit rod to slide relative to the limit sleeve, and after adjustment, screwing the fixing bolt into the fixing mouth and fixing the limit rod to adjust the depth of the trench to be dug.
