DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Referring to Figures 1-5 For an embodiment of the utility model, it discloses an automatic seeding machine unearthing mechanism, specifically the unearthing mechanism comprises a conveying line 1 and a frame 2 installed above the conveying line 1.

[0024] An unearthing assembly 3 and a hopper 4 are arranged on the inner side of the frame 2, and the hopper 4 is located above the unearthing assembly 3.

[0025] The hopper 4 and the frame 2 are connected by a locking assembly 5, and a soil scraping plate 6 is further arranged on one side of the frame 2 and is slidingly connected to the frame 2 by an adjusting assembly 7. In this embodiment, the height of the soil scraping plate 6 can be adjusted to change the unearthing thickness, thereby improving the operation applicability during the soil covering process of the seedling tray.

[0026] In some embodiments, the unearthing assembly 3 comprises two rollers rotatably connected to the inner side of the frame 2, and a conveying belt 31 is sleeved between the two rollers, and a motor 32 for driving one of the rollers to rotate is fixedly installed on the side edge of the frame 2.

[0027] In this embodiment, the motor 32 drives one of the rollers to rotate, thereby achieving the rotational driving of the conveying belt 31. As a preferred embodiment, a sliding seat is rotatably connected to the two ends of the roller not connected to the motor 32, and a sliding groove is formed on both sides of the frame 2, and the sliding seat is slidingly connected to the inner side of the sliding groove. In order to adjust the position of the sliding seat, a bolt is rotatably connected to the side edge of the frame 2, and the bolt is threadedly connected to the sliding seat. Thus, the position of the sliding seat can be adjusted by adjusting the bolt. The design of this structure can adjust the distance between the two rollers, and when the distance between the two rollers is adjusted during assembly, the tension of the conveying belt 31 can be adaptively adjusted to meet the convenience of assembly operation.

[0028] Further, the bottom of the hopper 4 in the embodiment has a stopper 41 in front of the conveying direction of the conveying line 1, which is attached to and above the conveying belt 31. The stopper 41 is designed to avoid the soil in the hopper 4 from falling from the rear side of the hopper 4, so as to ensure that the soil is stably conveyed forward and finally falls above the seedling tray. A channel 42 is formed between the rear side of the hopper 4 in the conveying direction of the conveying line 1 and the conveying belt 31, which is used for discharging the soil outward. The soil scraping plate 6 covers the channel 42, that is, the height of the cover plate soil scraping plate 6 can change the opening height of the channel 42. When the opening height of the channel 42 is reduced, thinner soil layer is allowed to pass, and vice versa, so as to meet the requirement of different thickness of the soil covering.

[0029] On the basis of the above embodiment, the locking assembly 5 in the embodiment includes a plug-in part 51 fixedly installed on the upper end of the frame 2 and a rotating part 52, which is rotatably connected with the plug-in part 51 through a shaft and a torsional spring. Specifically, the shaft is connected with the rotating part 52, and the torsional spring is connected between the rotating part 52 and the plug-in part 51. Of course, the upper end of the plug-in part 51 should be provided with a hole position for accommodating the torsional spring and the shaft.

[0030] A connecting wing 43 is further fixedly installed on the side of the hopper 4, which has a hole matched with the plug-in part 51. Specifically, the rotating part 52 and the plug-in part 51 in the embodiment are of the same shape, and are arranged in a staggered manner in the initial state. Thus, the rotating part 52 can be stopped on the upper side of the connecting wing 43 to complete the limiting and fixing of the hopper 4. Conversely, when the hopper 4 needs to be disassembled, the two rotating parts 52 on both sides are rotated, and the rotating part 52 and the plug-in part 51 are kept in vertical alignment. At this time, the rotating part 52 is separated from the upper side of the connecting wing 43, and the hopper 4 can be pulled upward to be disassembled. Thus, the lower soil discharging assembly 3 can be cleaned and maintained.

[0031] In some embodiments, the adjusting assembly 7 in the utility model includes two L-shaped plates 71 installed on the end face of the frame 2. The two ends of the L-shaped plate 71 are of open structure, and the two ends of the soil scraping plate 6 are provided with sliding parts 61, which slide in the two L-shaped plates 71.

[0032] The end face of the L-shaped plate 71 is provided with a plurality of positioning holes 72, and the end face of the sliding part 61 is embedded with a positioning glass bead 73, the extension end of which is clamped with the positioning hole 72.

[0033] During installation, first, the sliding parts 61 at both ends of the earth scraping plate 6 can be inserted between the two L-shaped plates 71, and when the thickness of the excavated earth needs to be changed, the height of the earth scraping plate 6 can be changed by sliding it up and down, and through the design of the plurality of positioning holes 72, the multi-position clamping and positioning of the positioning beads 73 can be achieved, so that the earth scraping plate 6 can have the ability to be fixed at multiple positions to adapt to the adjustment requirements of different excavation thicknesses.

[0034] It should be noted that the earth scraping plate 6 in the embodiment includes a flat part 62 and an inclined scraping part 63, and the inclined scraping part 63 is towards the rear of the conveying direction of the conveying line 1.

[0035] In summary, in the utility model, through the design of the adjustable earth scraping plate 6, when the thickness of the excavated earth needs to be changed, the height of the earth scraping plate 6 can be changed to adjust the thickness of the excavated earth, so as to improve the work applicability in the process of covering the seedling tray with earth, and secondly, the hopper 4 is designed in a detachable structure, which can be removed for cleaning when the machine is stopped, and at the same time, it is convenient to clean and maintain the lower side of the earth excavation assembly 3, so as to further optimize the applicability of the device.

[0036] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
