A type of wavy wire top cover seedling roller

Abstract

This utility model relates to the field of seedling rollers and discloses a corrugated wire top cover seedling roller, including a fixing block. Connecting frames are bolted to both sides of the fixing block. A threaded shaft is slidably mounted on one side of each of the two connecting frames. A top cover roller is rotatably mounted on the outer surface of the threaded shaft. The top cover roller includes two rotating rings, and multiple corrugated wires are fixedly mounted on the outer surface of the two rotating rings. The corrugated wires are wavy. Three support rings are fixedly mounted on one side of the multiple corrugated wires facing each other. A snap-fit ​​block is fixedly mounted on the rear end face of the fixing block. In this utility model, when the top cover roller, composed of rotating rings, support rings, and corrugated wires, rotates above the seedling soil, the unevenness of the corrugated wires allows the rotational speed to shake off the seedling soil adhering to the wires. Furthermore, the hollow interior of the top cover roller, with open ends, allows the seedling soil adhering to the roller to be thrown out from both ends, preventing the top cover roller from becoming heavier with use.

Description

Technical Field

[0001] This utility model relates to the field of seedling rollers, and in particular to a seedling roller with a corrugated wire top cover. Background Technology

[0002] Rice is an annual aquatic herbaceous plant belonging to the genus Oryza of the family Poaceae. According to the sowing season, it can be divided into early rice, mid-season rice, and late rice. Early rice has a shorter growing season, generally sown from late March to early April and harvested from mid to late July. Mid-season rice has a moderate growing season, generally sown from mid-April to mid-May and harvested from mid to late September. Late rice has a longer growing season, generally sown from mid to late June and harvested from late October to early November. Rice seedling raising is a key step in the rice planting process.

[0003] In Northeast China, rice cultivation involves raising seedlings in greenhouses to increase yield. The process begins with laying a base layer of soil before sowing. After sowing, the soil is covered, but the covering soil is often too sticky. Watering after covering creates a hard topsoil layer on the seeds, causing them to sprout and push through the soil, hindering seedling growth. Traditional methods to address this include beating with willow branches, lightly sweeping with brooms, rolling with sowing mats, and rolling with wire rollers. While wire roller rolling is a relatively advanced solution, it has several drawbacks. The best time for farmers to roll the topsoil is around midday when it's dry, maximizing the effect. However, the greenhouse temperature is very high at this time, making the process difficult. Therefore, most farmers choose to do it in the morning. But at this time, the topsoil is still damp, and the broken-up soil easily sticks to the rollers, becoming increasingly sticky and compacted over time, making it impossible to continue.

[0004] Therefore, those skilled in the art have provided a corrugated wire top cover seedling roller to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology and propose a wavy silk top cover seedling roller. Because the wavy silk is uneven, it can shake off the seedling soil sticking to the wavy silk when it rotates, so that the top cover roller will not become heavier and heavier with use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated wire top cover seedling roller, including a fixing block, with connecting frames bolted to both sides of the fixing block, and threaded shafts slidably arranged on one side of each of the two connecting frames;

[0007] A top cover roller is rotatably mounted on the outer surface of the threaded shaft. The top cover roller includes two rotating rings. Multiple corrugated wires are fixedly mounted on the outer surface of the two rotating rings. The corrugated wires are wavy. Three support rings are fixedly mounted on one side of the multiple corrugated wires.

[0008] Furthermore, a snap-fit ​​block is fixedly provided on the rear end face of the fixing block.

[0009] Furthermore, two fixing holes are provided on both sides of the snap-fit ​​block.

[0010] Furthermore, two fixing bolts are threaded onto the rear of opposite sides of both connecting brackets.

[0011] Furthermore, shims are slidably provided on both sides of the outer surface of the threaded shaft.

[0012] Furthermore, a first fixing nut is threaded onto both sides of the outer surface of the threaded shaft.

[0013] Furthermore, a second fixing nut is threaded onto both sides of the threaded shaft near the top cover roller.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a corrugated wire top-covered seedling roller. In Northeast China, rice seedlings are raised in the spring. During rice seedling raising, a layer of seedling soil is sprinkled on top of the seeds. Because the seedling soil is sticky and prone to clumping, it causes a top-covering phenomenon when the seeds germinate. After this phenomenon occurs, workers need to break the top layer of seedling soil. Currently, the method for breaking the seedling soil is to use a seedling roller. Existing seedling rollers are all flat rollers that roll on top of the seedling soil. Sometimes, due to the sticky nature of the soil, the seedling soil will stick to the seedling roller, making the seedling roller increasingly heavy. The top cover roller is composed of a rotating ring, a support ring, and corrugated wire. The corrugated wire is welded at an angle, making it easier to crush and pulverize the top cover soil. At the same time, because the surface of the corrugated wire is uneven, the top cover roller can more easily pierce the top cover soil when rolling. The two ends of the roller are hollowed out, and the top cover soil that enters the roller will be thrown out through the hollowed-out ends under the action of speed. In this way, the corrugated wire roller not only has a good crushing effect, but also makes it easier to throw off the sticky soil. Attached Figure Description
