Technical Field
[0001] The utility model belongs to the technical field of lettuce planting, in particular to a portable lettuce film seam planting machine. Background Art
[0002] Lettuce is mostly cultivated in the suburbs of large cities in my country. It prefers a cool climate and is suitable for an environment with a large temperature difference between day and night and lower temperature at night. It likes slightly acidic soil, and is best cultivated in sandy loam or loam with strong water retention and good drainage.
[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: in the production work of planting lettuce, personnel need to scatter lettuce seeds at the planting site, but the current sowing of lettuce seeds is usually irregular, and personnel directly scatter a handful of seeds on the ground (because the seeds are scattered too concentratedly, personnel need to sort them out later), resulting in uneven dispersion of the lettuce seeds.
[0004] To this end, we proposed a portable lettuce film seam planting machine to solve the above problems. Utility Model Content
[0005] The main purpose of the utility model is to provide a portable lettuce film seam planting machine, which can disperse the lettuce seeds more evenly after being spread out, eliminating the trouble of subsequent manual sorting of the lettuce seeds, and can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] The portable lettuce film-sewn planting machine comprises a material box, which is fixedly mounted on a back plate, and two shoulder straps are symmetrically connected to one side of the back plate facing away from the material box, so that a person can carry the material box on his back through the two shoulder straps;

[0009] A bottom bracket and a discharge pipe are fixedly connected to the bottom wall of the material box. The bottom bracket is U-shaped, and a servo motor is installed on the bottom wall of the bottom bracket. The servo motor needs to be powered by external power facilities. The output shaft of the servo motor is coaxially connected to the discharge tray. The opening of the inner cavity of the discharge tray is located on its top wall. The discharge pipe extends into the inner cavity of the discharge tray. A circle of membrane seams is formed on the bottom wall of the discharge tray to disperse the lettuce seeds.
[0010] As a preferred embodiment, a screw cap is screwed on the opening at the top of the feeding tube; thus, the feeding tube is closed by the screw cap.
[0011] As a preferred implementation scheme, a pulley is installed on the other side of the inner frame, and a side support plate is fixedly welded on the side of the inner cavity of the material box facing away from the cylinder, and the pulley is rolled on the side support plate; when the inner frame and the screen are translated, the pulley is driven to roll on the side support plate, so that the inner frame and the screen structure remain stable.
[0012] As a preferred embodiment, a cover is also fixedly bonded to the bottom wall of the bottom bracket, wherein the servo motor is located inside the cover; so that the cover can protect the servo motor.
[0013] As a preferred embodiment, a plurality of micro holes penetrating the top wall and the bottom wall of the sieve are provided, so that the lettuce seeds can pass through the micro holes, while the large particles of impurities contained therein are intercepted on the sieve.
[0014] As a preferred embodiment, the multiple film slits on the bottom wall of the discharge tray are distributed in a circular array along the central axis of the discharge tray; thereby facilitating the uniform spreading of the lettuce seeds through the multiple film slits.
[0015] In summary, the technical effects and advantages of the utility model are as follows:
[0016] The portable lettuce film-seam planting machine drives the discharging plate to rotate at a uniform speed through the operation of the servo motor, so that the lettuce seeds are dispersed through multiple film slits and scattered at various places at the rear of the material box, so that the lettuce seeds are dispersed more evenly after being scattered, eliminating the trouble of subsequent manual arrangement of the lettuce seeds, and because the material box 1 can be carried on the back, its portability is achieved;
[0017] In the portable lettuce film seam planting machine, a person carries a material box and a backboard on his shoulders with two shoulder straps, so that the discharge tray is located on his back. The person walks around the lettuce planting site with the material box on his back, and opens the discharge pipe with a valve. The lettuce seeds slowly fall into the discharge tray, and the servo motor is driven to drive the discharge tray to rotate at a uniform speed, so that the lettuce seeds fall into the discharge tray and are dispersed and scattered through multiple film seams, ensuring that the distribution of the lettuce seeds is more dispersed and uniform.
