Utility Model Content

[0003] In view of this, this application provides a seeding and sand covering machine to solve the technical problem of performing seeding and sand covering operations separately in the existing system, so as to improve work efficiency and save time.

[0009] A seeding device is mounted on the frame. When the walking wheels move, they can drive the first transmission mechanism to drive the seeding device to perform multiple sets of synchronous seeding.

[0010] A pressure roller, which is mounted on the frame;

[0011] A second transmission mechanism is connected to the pressure roller;

[0012] A sand-covering device is installed on the frame. When the pressure roller moves, it can drive the second transmission mechanism to drive the sand-covering device to synchronously drop and cover sand.

[0013] Furthermore, the seeding device includes a frame and several seeding components arranged side by side on the frame, the frame being mounted on the machine frame.

[0014] Furthermore, the seeding assembly includes:

[0015] Seeding box, which is mounted on the frame;

[0016] Seed bin, which is located above the seed box;

[0017] The seed metering turntable is driven by the first transmission mechanism so as to be linked with the walking wheels, thereby causing the seed metering turntable to rotate in the frame to realize the quantitative sowing of seeds in the seed bin.

[0018] Furthermore, the seed metering turntable has several seed metering grooves arranged in a ring on it.

[0019] Furthermore, the seeding box has an inner cavity, in which the seed metering turntable can rotate. The upper end of the inner cavity is connected to the seed bin, and the lower end of the inner cavity is provided with a seeding tube, through which the seeds in the seed bin can fall onto the soil.

[0020] Furthermore, the sand-covering device includes:

[0021] A sand-feeding assembly, which is mounted on the frame;

[0022] The sand-pressing component is installed below the frame. After the sand-discharging component discharging sand onto the seeds, the sand-pressing component compacts the sand.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0047] refer to Figures 1 to 9 ,like Figure 1 and Figure 2As shown, this embodiment provides a seeding and sand-covering machine, including: a frame 10, traveling wheels 11, a transmission mechanism, a seeding device 40, a pressure roller 17, and a sand-covering device 50. The frame 10 is pulled by a traction mechanism 100; the traveling wheels 11 are connected to the frame 10, and the traction mechanism 100 can pull the frame 10 to move; the transmission mechanism is installed on the frame 10, and the transmission mechanism includes a first transmission mechanism 20 and a second transmission mechanism 30, the first transmission mechanism 20 being connected to the traveling wheels 11; the seeding device 40 is installed on the frame 10, and when the traveling wheels 11 move, they can drive the first transmission mechanism 20 to drive the seeding device 40 to perform multiple sets of synchronous seeding; the pressure roller 17 is installed on the frame 10, and the second transmission mechanism 30 is connected to the pressure roller 17; the sand-covering device 50 is installed on the frame 10, and when the pressure roller 17 moves, it can drive the second transmission mechanism 30 to drive the sand-covering device 50 to perform synchronous sand application and coverage.

[0048] like Figure 3 and Figure 4 As shown, a first protective shell 12 is provided on the outer side of the first transmission mechanism 20. The first protective shell 12 is connected to the frame 10. Specifically, the first transmission mechanism 20 includes a pair of first driving sprockets 21, a pair of first chains 22 and a pair of first driven sprockets 23. The pair of first driving sprockets 21 and the pair of first driven sprockets 23 are installed opposite to each other on the front and rear sides of the frame 10 in the front-rear direction. The first chains 22 are connected between the corresponding first driving sprockets 21 and the corresponding first driven sprockets 23. The pair of first driving sprockets 21 are connected together by the first shaft 14 of the traveling wheel 11.

[0049] In this embodiment of the application, the traction mechanism 100 includes a pair of traction frames, which are connected to the frame 10. When sowing, the user stands between the pair of traction frames, grabs the traction frames with both hands and pulls them forward to move the walking wheels 11 forward.

[0050] Furthermore, to reduce labor intensity, a drive mechanism 60 is also provided on the frame 10. The drive mechanism 60 includes a solar panel 61, a battery 62, and a drive motor 63. The solar panel 61 and the battery 62 are spaced apart on the frame 10. The drive motor 63 is connected to the first rotating shaft 14. The solar panel 61 is electrically connected to the battery 62, and the battery 62 is electrically connected to the drive motor 63. The solar panel 61 can absorb the energy of sunlight and convert it into electrical energy stored in the battery 62, so that the battery 62 can provide power support for the drive motor 63. When the drive motor 63 starts, it can drive the walking wheels 11 to rotate and move. This allows the operator to control the direction of movement when walking in the field without having to exert force to pull the whole machine forward, thus saving energy and reducing labor intensity. It should be noted that the working method of the solar panel 61, battery 62, and drive motor 63 in this application is a common technical means in the prior art that can realize energy storage and power supply, so it will not be explained in detail here.

[0051] In addition, for ease of use, a handrail is provided at the end of the traction frame for easy hand holding, and a control button is installed on one of the handrails, which can be used to control the operation and stop of the drive motor 63.

[0052] In one implementation scheme, when the control button is pressed, the drive motor 63 starts working, allowing the entire unit to move; when the button is released, the drive motor 63 stops working, stopping the entire unit from moving. This on-demand movement method makes it more convenient to use in the field.

[0053] Preferably, a pair of first driven sprockets 23 are connected together via a first drive shaft 24.

[0054] In this embodiment of the application, the sowing device 40 includes a frame 44, a plurality of transmission components and a plurality of sowing components arranged side by side on the frame 44. A first fixed shaft 15 and a second fixed shaft 16 are spaced apart on the frame 10. The frame 44 is connected to the first fixed shaft 15 and the second fixed shaft 16 so that the frame 44 is mounted on the frame 10. The transmission components correspond to the sowing components and are connected between the sowing components and the first transmission shaft 24.

[0055] like Figure 3 and Figure 4 As shown, the sowing assembly includes: a sowing box 45, a seed bin 46, and a seed metering turntable 47. The sowing box 45 is mounted on the frame 44; the seed bin 46 is mounted above the sowing box 45; the seed metering turntable 47 is connected to a corresponding transmission assembly, and several seed metering turntables 47 are linked with the traveling wheels 11. The rotation of the seed metering turntable 47 within the frame 44 enables quantitative sowing of seeds in the seed bin 46.

[0056] Preferably, the transmission assembly includes: a first driving gear 41, a first driven gear 42, and a first drive shaft 43. The first driving gear 41 is connected to the first transmission shaft 24, the first driven gear 42 is meshed with the corresponding first driving gear 41, the first driven gear 42 is connected to the rear end of the corresponding first drive shaft 43, and a plurality of seeding turntables 47 are spaced apart on the first drive shaft 43. The rotation of the first drive shaft 43 can drive the plurality of seeding turntables 47 to operate synchronously.

[0057] like Figure 5 As shown, the seed box 45 has an inner cavity 451, and the seed metering turntable 47 can rotate in the inner cavity 451. The upper end of the inner cavity 451 is connected to the seed bin 46, and the lower end of the inner cavity 451 is provided with a seed pipe 452. When this application moves to the right, the seeds in the seed bin 46 can fall onto the soil.

[0058] like Figure 6 As shown, the seed metering turntable 47 has several seed metering grooves 471 arranged in a ring. When the seed metering turntable 47 rotates, the seeds in the seed bin 46 fall into the seed metering grooves 471 below. As the seed metering turntable 47 rotates, the seeds in the seed metering grooves 471 will fall onto the soil, thereby realizing sowing.

[0059] like Figure 7 As shown, a second protective shell 13 is provided on the outer side of the second transmission mechanism 30. The second protective shell 13 is connected to the frame 10. Specifically, the second transmission mechanism 30 includes a pair of second driving sprockets 31, a pair of second chains 32 and a pair of second driven sprockets 33. The pressure roller 17 is mounted on the frame 10 through a third rotating shaft 18. The pair of second driving sprockets 31 are respectively connected to the front and rear ends of the third rotating shaft 18. The second chains 32 are connected between the corresponding second driving sprockets 31 and the corresponding second driven sprockets 33. The pair of second driven sprockets 33 are connected together through a fourth rotating shaft 19.

[0060] like Figure 7 , Figure 8 and Figure 9 As shown, the sand covering device 50 includes a sand-feeding component and a sand-pressing component. The sand-feeding component is mounted on the frame 10 and connected to the fourth rotating shaft 19. The sand-pressing component is installed below the frame 10. After the sand-feeding component dispenses sand onto the seeds on the soil, the sand-pressing component compacts the sand and simultaneously presses the seeds into the soil. By covering the soil with sand, soil evaporation can be effectively suppressed, soil moisture can be retained, and the soil environment can be improved.

[0061] Specifically, the sand compaction assembly includes a pair of support legs 52 and a sand compaction wheel 53. The pair of support legs 52 are arranged opposite each other under the frame 10, and the sand compaction wheel 53 is installed between the pair of support legs 52. The sand compaction wheel 53 can compact the sand by rolling.

[0062] like Figure 10 As shown, the sand feeding assembly includes: a sand hopper 51, a guide assembly, and a conveying assembly. The sand hopper 51 is connected to the frame 10, and sand is stored inside the sand hopper 51. The guide assembly is disposed inside the sand hopper 51. The conveying assembly is connected to a pair of support legs 52. The conveying assembly is used to convey sand falling from the sand hopper 51 and guided by the guide assembly. The conveying assembly is connected to the second transmission mechanism 30 of the transmission mechanism so that the conveying assembly is linked with the pressure roller 17.

[0063] Preferably, the guiding assembly includes a first inclined plate 57 and a second inclined plate 58, which are arranged opposite to each other in the sand hopper 51, such that the lower ends of the first inclined plate 57 and the second inclined plate 58 have sand inlets 59. The conveying assembly is located below the sand inlets 59. By setting the sand inlets 59, the sand falling speed can be prevented from being too fast.

[0064] Preferably, the conveying assembly includes a driving pulley 54, a transmission belt 55, and a driven pulley 56. The driving pulley 54 and the driven pulley 56 are spaced apart. The driving pulley 54 is connected to the fourth rotating shaft 19, and the driven pulley 56 is located between a pair of support feet 52. The transmission belt 55 is connected between the driving pulley 54 and the driven pulley 56. The transmission belt 55 is located below the sand inlet 59, and there is a space between them. The height of this space is limited, which can prevent too much sand from flowing downward and accumulating on the transmission belt 55, thereby achieving quantitative sand delivery.

[0065] Preferably, the drive pulley 54 is positioned slightly to the right of the sand-pressing wheel 53, so that the sand is flattened by the sand-pressing wheel 53 after it falls inside.

[0066] In this embodiment of the application, the sowing spacing is 23cm, and the number of seeds sown at one time is 5-10; the sand covering thickness is 1-1.5cm, that is, covering the seeds with 1-1.5cm of fine sand, which is beneficial for retaining moisture and increasing temperature, and preventing soil compaction.

[0067] Working principle: This application uses a traction mechanism 100 for traction and a drive mechanism 60 for drive, so that the walking wheel 11 and the pressure wheel 17 move in the field. The walking wheel moves and drives a pair of first driving sprockets 21 to rotate through the first rotating shaft 14. Then, a pair of first chains 22 drive a pair of first driven sprockets 23 to rotate. Then, a first transmission shaft 24 drives multiple first driving gears 41 to rotate. The first driving gears 41 drive the corresponding first driven gears 42 to rotate. The first driven gears 42 drive the seed metering turntable 47 to rotate through the first drive shaft 43. So, the seeds in the seed bin 46 first fall into the seed metering groove 471. As the seed metering turntable 47 rotates, the seeds fall into the lower end of the inner cavity 451, and then fall onto the soil through the seed tube 452. At this time, the sowing is completed.

[0068] The movement of the pressure roller 17 drives the sand-pressing roller 53 to rotate, which in turn drives a pair of second driving sprockets 31 to rotate via the third rotating shaft 18. This, in turn, drives a pair of second driven sprockets 33 via a pair of second chains 32. The fourth rotating shaft 19 drives the driving pulley 54 to rotate, thus rotating the transmission belt 55. Because the transmission belt 55 is close to the sand inlet 59, the amount of sand it can transport is limited when it rotates. This ensures that a fixed amount of sand falls onto the seeds in the soil, and then the sand is flattened by the sand-pressing roller 53.

[0069] When the traction mechanism 100 stops, the walking wheel 11, the pressure wheel 17, and the sand-pressing wheel 53 stop moving forward, so that the first transmission mechanism 20 and the second transmission mechanism 30 cannot rotate. Therefore, the seed metering turntable 47 and the drive pulley 54 cannot rotate, so that sowing and sand covering stop. Therefore, this application can not only combine sowing and sand covering into one unit, improving work efficiency, but also realize quantitative sowing and sand covering while walking, making sowing and sand covering more uniform.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
