Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting equipment, in particular to a device for loosening the hard soil covering crop seeds. Background Art

[0002] In order to promote the growth of crops, when sowing crops such as corn, it is usually necessary to lay plastic films. The most prominent effect of the plastic film is to increase temperature and preserve soil moisture, making up for the deficiencies of temperature, light, and water resources; in actual operation, ridges are first formed, and then the plastic film is laid. The plastic films on both sides of the ridges are pressed with soil to prevent them from being lifted by the wind. After several days of sunlight irradiation, sowing is carried out after the temperature inside the ridges gradually rises; when sowing, a small shovel or a punching tool is used to break the plastic film and punch holes on the ridges according to the plant spacing, and then the holes in the film are covered with soil after sowing, and wait for the seedlings to emerge after the seeds germinate.

[0003] In the actual planting process, after sowing, during the stage when the seeds germinate and the seedlings break through the soil, it is found that some seedlings are difficult to emerge for a long time. The reason is that after rain, the soil covering around the seeds is compacted, which is not conducive to the seedlings of the germinated seeds to push out from the soil, affecting the normal growth of crops, especially in the case of sticky soil. At present, the treatment method is that the planters assist in loosening the soil covering the seeds that have not broken through the soil to facilitate the emergence of seedlings, but there are problems of high labor intensity and low efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for loosening the hard soil covering crop seeds, which is beneficial to improving the soil loosening efficiency to facilitate the growth of seedlings breaking through the soil.

[0005] The utility model is implemented by the following technical solutions: A device for loosening the hard soil covering crop seeds, which includes a pressure roller, a soil loosening support, a traction rod, a connecting rod, and a soil loosening component; both ends of the pressure roller are coaxially fixed with connecting shafts, and each connecting shaft is slidably sleeved with a connecting sleeve. The side wall of the connecting sleeve is fixedly connected with one end of the connecting rod, and the other end of the connecting rod is connected with the soil loosening support; the soil loosening component includes a plurality of soil loosening ribs arranged and fixed circumferentially around the pressure roller, and each soil loosening rib is obliquely arranged relative to the axis of the pressure roller; a traction rod is fixed on the side of the soil loosening support facing away from the pressure roller.

[0006] Further, it includes two groups of symmetrical soil loosening components. Each group of soil loosening components further includes a fixing ring sleeved on the pressure roller. The fixing ring is fixed on the pressure roller. One end of the soil loosening rib is fixedly connected with the fixing ring, and the other end of the soil loosening rib is bent downward and fixedly connected with the side wall of the end of the pressure roller.

[0007] Further, the soil loosening bracket includes two parallel cross beams and an intermediate shaft fixed between the two cross beams; the other end of each connecting rod is fixed with a sliding sleeve sleeved on the intermediate shaft.

[0008] Further, two limiting sleeves are slidably sleeved on the intermediate shaft between the two sliding sleeves, a locking screw is inserted and screwed on each limiting sleeve, the end of the locking screw abuts against the intermediate shaft, and the sliding sleeve is in movable contact with the corresponding limiting sleeve.

[0009] Further, a limiting nut is sleeved and screwed at the end of each connecting shaft.

[0010] Further, a counterweight rod is fixed at the top of the soil loosening bracket, and counterweight blocks are sleeved at both ends of the counterweight rod.

[0011] Advantages of the present utility model: Driven by an agricultural machine, the soil loosening bracket and the connecting rods drive the pressing roller to rotate, and each soil loosening rib on the pressing roller sequentially contacts the covering soil. When each soil loosening rib contacts the ground, one end of it first contacts the ground and gradually penetrates into the covering soil. During the rotation of the pressing roller, the soil loosening rib gradually extends into the covering soil from one end to the other end, effectively loosening the compacted soil. Thus, after the crops are sown and before the seedlings emerge, the present utility model can efficiently loosen the compacted soil of the crop seeds, effectively reducing the labor intensity and simultaneously increasing the emergence rate of the subsequent seedlings.
