Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed drill. Background Art

[0002] In the context of the rapid development of modern agricultural technology, the seeder is the core equipment for improving agricultural production efficiency and achieving precision sowing. The traditional sowing method relies on manual labor, which is not only time-consuming and labor-intensive, but also difficult to ensure the uniformity and consistency of sowing depth, which seriously affects the germination rate and subsequent growth quality of crops. Therefore, in recent years, the seeder technology has undergone a transformation from simple mechanical to automated. The emergence of the seeder not only greatly improves the accuracy and efficiency of sowing operations, but also plays a positive role in promoting the sustainable development of agriculture by reducing seed waste and optimizing resource utilization. However, for a seed with long awns, cotton wool, thorns or appendages, during the sowing process, due to the poor fluidity of the seed, the seed at the lower end of the silo is prone to arching, resulting in discontinuous feeding, resulting in poor sowing uniformity, which needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a seed drill.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A seeder comprises a frame, two traveling wheels installed on both sides of the frame, multiple sets of unloading mechanisms installed on the frame, a ditching mechanism installed on the frame and corresponding to the unloading mechanisms, and a soil covering mechanism; the unloading mechanism comprises a silo fixedly connected to the frame, a unloading shaft rotatably installed on the frame and passing through each silo, and a unloading pipe located at the lower end of the silo; the unloading shaft is transmission-connected to the center of the traveling wheel through a sprocket mechanism; it is characterized in that: a mounting frame is provided on one side of the frame, a stirring shaft parallel to the unloading shaft is rotatably installed on the mounting frame, the stirring shaft rotates through each silo and is located above the unloading shaft; the portion of the stirring shaft located in the silo is fixedly connected to a stirring rod; the stirring shaft and the unloading shaft are transmission-connected through a transmission mechanism.

[0006] Preferably, the soil covering mechanism is a plurality of sets, the number of which is the same as that of the unloading mechanism and is located behind the unloading mechanism; the soil covering mechanism includes a soil covering block, two drag chains respectively located at the two ends of the soil covering block and fixedly connected to the soil covering block at these ends, and two soil covering rods fixedly connected to the lower end of the soil covering block; the other end of the drag chain is fixedly connected to the frame; the two soil covering rods are arranged in an eight-shaped shape, and the end with a larger opening faces the ditching mechanism.

[0007] Preferably, a front leveling wheel is rotatably mounted on the frame in front of the ditching mechanism, and a rear leveling wheel is rotatably mounted on the frame behind the ditching mechanism.

[0008] Preferably, a connecting frame for connecting to a traction machine is installed on the frame.

[0009] Preferably, a push rod is installed on the frame.

[0010] Preferably, a silo cover is provided at the upper end of the silo.

[0011] Preferably, the transmission mechanism includes a driven pulley fixedly connected to the stirring shaft, a driving pulley fixedly connected to the discharge shaft, and a transmission belt wound around the driven pulley and the driving pulley.

[0012] The above technical solution has the following advantages:

[0013] (1) The utility model can effectively avoid discontinuous feeding caused by the seeds in the lower part of the silo being arched due to poor flow by adding a stirring shaft at the lower part of the silo, thereby effectively ensuring the continuity of sowing, especially suitable for sowing seeds with long awns, cotton wool, thorns or appendages.

[0014] (2) The utility model adopts a new soil covering mechanism, which has a relatively stable weight acting on the soil covering, thereby effectively ensuring that the soil covering is compacted more uniformly, avoiding the situation where the soil covering is too compact or insufficient.

DETAILED DESCRIPTION

[0022] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings.
