Abstract
Description
Technical Field
[0001] This utility model relates to the field of seedling raising machine technology, specifically a seedling raising machine for double-cropping of Chinese cabbage. Background Technology
[0002] Multiple cropping is a planting method in which more than one crop is planted and harvested on the same cultivated land in a year. In the process of multiple cropping of Chinese cabbage, seedling raising machines are usually used to complete the seedling raising process of Chinese cabbage.
[0003] For example, a wide-width, automatically adjustable seedling raising machine with authorization announcement number CN222030465U uses a second motor to drive a screw to rotate, causing a moving block to move along the screw, which in turn moves an L-shaped rod along the inside of the soil discharge trough, thereby adjusting the size of the soil discharge opening and thus adjusting the soil covering width, improving the practicality of the device. Furthermore, when the L-shaped rod moves, it moves baffles, using the position between the baffles to limit the seedling trays, ensuring that seedling trays of different sizes are accurately aligned with the soil discharge trough, guaranteeing accurate soil covering. However, after using the aforementioned document to cover cabbage seedling trays with soil, because the soil discharge trough below the covering machine is not sealed, the soil inside the covering machine easily slips to the outside after covering, causing waste and requiring manual cleaning, increasing the labor intensity of personnel. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a seedling raising machine for double-cropping of Chinese cabbage.

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] See attached document Figure 1-5 A seedling raising machine for replanting Chinese cabbage includes a soil covering machine 1 and an auxiliary structure 9. The auxiliary structure 9 is provided on one side of the soil covering machine 1. The auxiliary structure 9 includes a rack 901, a gear 902, a rack 903, a support rod 904, a soil retaining strip 905, a guide seat 906, and a slider 907.
[0022] Multiple support rods 904 are respectively arranged on both sides of the backfilling machine 1. The end of the support rods 904 away from the backfilling machine 1 is rotatably equipped with a gear 902. The two sides of the gear 902 are respectively engaged with rack 1 901 and rack 2 903. One end of rack 2 903 is fixedly connected to retaining strip 2 905. One side of retaining strip 2 is slidably connected to guide seat 906. Both ends of guide seat 906 are fixedly connected to backfilling machine 1. One end of the inner wall of guide seat 906 is fixedly connected to slider 907. The outer wall of slider 907 is slidably connected to retaining strip 2 905. Slider 907 is used to guide and restrict retaining strip 2 905 to prevent retaining strip 2 905 from detaching from backfilling machine 1 during movement.
[0023] Both sides of the retaining strip 905 have their outer walls in contact with the backfilling machine 1. Both ends of the retaining strip 905 are also in contact with the backfilling machine 1. The end of the retaining strip 905 furthest from the rack 903 is angled to prevent gaps from forming between the two retaining strips 905 when they are joined. One end of the rack 901 is fixedly connected to the retaining strip 8. The retaining strip 8 is located below the retaining strip 905, and its outer wall is in contact with the backfilling machine 1. The side of the retaining strip 8 furthest from the rack 901 is angled to prevent soil accumulation on the retaining strip 8. At the upper end, the soil retaining strip 8 can drive the rack 901 to move during the movement. The rack 901 drives the gear 902 to rotate along the support rod 904. The support rod 904 drives the rack 903 to move. The rack 903 drives the soil retaining strip 905 to move. The soil retaining strip 905 slides along the guide seat 906. The direction of movement of the soil retaining strip 905 is opposite to that of the soil retaining strip 8. The soil retaining strip 905 is used to block the soil discharge trough of the covering machine 1 to prevent the soil inside the covering machine from falling to the outside when the covering of the cabbage seedling trays is stopped.
[0024] The lower end of retaining strip 8 is fixedly connected to connecting rod 7, and the other end of connecting rod 7 is fixedly connected to baffle 5. Both baffles 5 are threadedly connected to screw rod 4. Screw rod 4 is a double-ended screw rod. The motor 3 drives screw rod 4 to rotate, which can drive the baffles 5 on both sides to move in opposite directions. The baffles 5 can drive connecting rod 7 to move, and connecting rod 7 can drive retaining strip 8 to move. The spacing between retaining strips 8 on both sides can be adjusted by the position of the retaining strips 8, thereby adjusting the soil cover width. The cabbage seedling trays are limited by the baffles 5 on both sides, so that the seedling trays of different sizes can be accurately aligned with the soil discharge trough of the covering machine. The screw 4 has opposite thread directions on both sides, and both sides of the screw 4 are rotatably connected to the covering machine 1. One end of the screw 4 is fixedly connected to the output shaft of the motor 3, and the fixed end of the motor 3 is fixedly connected to the covering machine 1. The upper part of the baffles 5 on both sides is slidably connected to the guide rod 6, and both ends of the guide rod 6 are fixedly connected to the covering machine 1. The lower end of the covering machine 1 is equipped with a conveyor 2, which is used to transport the cabbage seedling trays.
[0025] Specifically, the motor 3 drives the screw 4 to rotate, which in turn moves the baffles 5 on both sides in opposite directions. The baffles 5 move the connecting rod 7, which in turn moves the retaining strip 8. The spacing between the retaining strips 8 is adjusted by the position of their resting points, thus adjusting the soil covering width. The baffles 5 also limit the movement of the cabbage seedling trays, ensuring that seedling trays of different sizes are accurately aligned with the soil discharge trough of the covering machine. The retaining strip 8... During the movement, it can drive rack 1 901 to move, rack 1 901 drives gear 902 to rotate along support rod 904, support rod 904 drives rack 2 903 to move, rack 2 903 drives retaining strip 2 905 to move, retaining strip 2 905 slides along guide seat 906, the direction of movement of retaining strip 2 905 is opposite to the direction of movement of retaining strip 1 8, retaining strip 2 905 is used to block the soil discharge trough of the covering machine 1 to prevent the soil inside the covering machine from falling to the outside when the covering of cabbage seedling trays is stopped.
