Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a vegetable seedling raising and dense planting machine. Background Art

[0002] At present, vegetable planting has formed regional scale advantages in some areas and has become a local pillar industry. In the process of vegetable planting, due to the light weight of seeds, most of the operations are fine, especially in the seedling stage, single seed sowing is generally implemented. In addition, the price of vegetable seeds is relatively high, so it is even more necessary to ensure the seedling rate of single seeds. There are some existing equipment that can weave seeds into ribbons at equal distances to form seed ribbons, and wrap them around wheel-shaped devices. Finally, the seed ribbons are placed in the soil by manual or other means to complete the planting.

[0003] The Chinese patent application number 201710302170.9 discloses an agricultural machine, specifically a vegetable seedling dense planting machine, including a wire wheel, a wire wheel frame, and a positioner. The wire wheel is wrapped with a seed ribbon. The wire wheel frame is used to install and fix the wire wheel. The positioner is used to fix the starting end of the seed ribbon. The wire wheel frame includes a bracket, an axle rod, and a perforated plate. The front end of the bracket is a perforated plate. The wire wheel is arranged in a single layer or multiple layers on the wire wheel frame. The perforated plate is detachable or split. The wire wheel is provided with a damping device. The axle rod is arranged vertically in the longitudinal direction. The above makes it easy to bury the seed ribbon in the soil when working in the field. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 6 As shown, the vegetable seedling dense planting machine includes a door frame 1, a first fixed shaft 2 is fixed at the lower end of the door frame 1, and moving wheels 4 are fixed at both ends of the first fixed shaft 2. The moving wheels 4 are solid rubber wheels, which are convenient for rapid movement and have a long service life without tire blowouts. A plurality of soil coverers 3 are fixed on the extension direction of the first fixed shaft 2, which are used to scrape soil and cover it on the seed webbing. Two fixed cards 5 are symmetrically fixed on one side of the middle part of the door frame 1, and a third fixed shaft 6 is rotatably installed in the fixed card 5. A plurality of wire wheels 7 are rotatably installed on the third fixed shaft 6. The seed webbing is coiled on the wire wheel 7, and the wire wheel 7 can ensure that all the seed webbings are rotated at the same time as the third fixed shaft 6 rotates. Step unwinding, two adjacent wire wheels 7 are directly provided with a limit clamp 8 clamped on the third fixed shaft 6, which is used to adjust the position of the wire wheel 7, two cross arms 9 are symmetrically fixed on the other side of the portal frame 1, and a second fixed shaft 10 is rotatably installed between the two cross arms 9, and a plurality of rope pressing wheels 11 are fixed on the second fixed shaft 10 at equal intervals, and the soil cover 3 is fixed on the side close to the rope pressing wheel 11. The number of soil cover 3, wire wheel 7 and rope pressing wheel 11 is the same and each wire wheel 7 corresponds to a soil cover 3 and a rope pressing wheel 11, and a rope fixing groove 12 is formed on the midline of the outer circle of the rope pressing wheel 11. When in use, the seed webbing is laid out from the rope fixing groove 12 as the rope pressing wheel 11 rotates.

[0022] In this embodiment, the cross arm 9 is fixed between the first fixed shaft 2 and the fixed clamp 5, so that the rope pulley 11 can contact the ground after the portal frame 1 is tilted.

[0023] In this embodiment, the soil covering device 3 includes a fixed base 31 fixed on the first fixed shaft 2, a lower fixed shaft 33 is fixed at the lower end of the fixed base 31, a Y-shaped scraper plate 34 is rotatably installed on the lower fixed shaft 33, an upper fixed shaft 32 is fixed at the upper end of the fixed base 31, spring fixed shafts 35 are fixed on both sides of the upper end of the Y-shaped scraper plate 34, and the spring fixed shaft 35 and the upper fixed shaft 32 are connected together by a tension spring 36. When the rope pressure wheel 11 rolls in the groove, the Y-shaped scraper plate 34 contacts both sides of the groove, scrapes the soil on the side wall of the groove and covers it on the seed webbing laid flat on the bottom of the groove to form a covering layer.

[0024] In this embodiment, an auxiliary handle is welded at the center of one end of the portal frame 1 away from the first fixed axis 2, so as to facilitate pulling the auxiliary handle more comfortably during operation.

[0025] The working principle of the utility model is as follows: when in use, the wire wheel 7 wound with the seed webbing is fixed on the third fixed shaft 6, and then the third fixed shaft 6 is fixed on the fixed card 5. When only the pulling device needs to be moved, the rope pressing wheel 11 is kept upward to pull the door frame 1 to move the position. When the seed webbing needs to be buried in the soil for vegetable seedling cultivation, the rope pressing wheel 11 is rotated to make it contact with the soil, and the seed webbing is passed through the rope fixing groove 12. The free end is fixed to one end of the field ridge. Then, the door frame 1 is pressed downward so that the rope pressing wheel 11 is pressed into the soil and then the device is pulled to move. During the movement of the device, the rope pressing wheel 11 crushes the seed webbing into the soil, and at the same time, the soil covering device 3 hangs the soil on the seed webbing to complete the soil covering operation.

[0026] Components not described in detail herein are prior art.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
