[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a garlic planting device for easy adjustment of furrow depth, comprising a crossbeam and a controller. Rollers are rotatably connected to both ends of the crossbeam. A column is fixedly connected to the middle of the upper surface of the crossbeam. A connecting plate is vertically rotatably connected to the upper end of the column. A furrowing wheel is rotatably connected to the other end of the connecting plate. A drive assembly for driving the furrowing wheel to rotate is provided on the connecting plate. An adjustment assembly for driving the connecting plate to rotate up and down is provided on the crossbeam. A planting box is fixedly connected to the middle of the crossbeam. A dredging and conveying component is provided inside the planting box to prevent blockage.

[0007] Preferably, a number of breaking teeth are fixedly connected to the circumferential surface of the grooved wheel, and the two adjacent breaking teeth are staggered in a figure-eight shape.

[0008] Preferably, the drive assembly includes a sprocket one rotatably connected to the connecting plate, a sprocket two fixedly connected to the middle shaft of the grooved wheel extending to the other side of the connecting plate, the sprocket two being connected to the sprocket one via chain drive, and a motor one for driving the sprocket one to rotate fixedly installed on the connecting plate, the input end of the motor one being electrically connected to the output end of the controller.

[0009] Preferably, the diameter of the first sprocket is smaller than that of the second sprocket.

[0010] Preferably, the adjustment assembly includes a movable block that moves on a crossbeam, and a linkage rod is connected between the movable block and the bottom surface of the connecting plate. Both ends of the linkage rod are connected to the movable block and the connecting plate respectively through hinge seats.

[0011] Preferably, the crossbeam has a groove that slides with the movable block. Both the movable block and the groove have T-shaped cross sections. A threaded rod is rotatably connected in the groove. The movable block has a threaded hole that is threadedly connected to the threaded rod. A second motor for driving the threaded rod to rotate is fixedly installed on the crossbeam. The input end of the second motor is electrically connected to the output end of the controller.

[0012] Preferably, the upper end of the seeding box is fixedly connected to an inverted conical box, the bottom of the inverted conical box is fixedly connected to an inclined guide plate, the lower end of the inclined guide plate and the lower opening of the inverted conical box are matched to form a first discharge port, the upper end of the seeding box is fixedly connected to an arc-shaped guide plate adapted to the first discharge port, and the unblocking conveyor is located above the arc-shaped guide plate. The bottom of the seeding box is a slope block adapted to the end of the arc-shaped guide plate, the lower end of the slope block and the lower opening of the seeding box are matched to form a second discharge port, and the seeding box and the furrowing wheel are on the same straight line.

[0013] Preferably, the unblocking and conveying component includes a rotating shaft rotatably connected in the seeding box, a spiral plate fixedly connected to the rotating shaft, the diameter of the spiral plate being adapted to the arc-shaped guide plate, and a motor three for driving the rotating shaft to rotate is fixedly installed on the side wall of the seeding box, the input end of the motor three being electrically connected to the output end of the controller.

[0016] The beneficial effects are:

[0017] The controller controls motor one to drive the furrowing wheel to rotate, and then controls motor two to drive the threaded rod to rotate. The moving block is threadedly connected to the moving rod, which moves the lower end of the linkage rod. The linkage rod drives the connecting plate to rotate and move downwards. During the downward movement, the rotating furrowing wheel opens a pit in the ground. The controller controls the movement of the agricultural vehicle. The rotating furrowing wheel can open furrows in the ground, which realizes the rapid adjustment of the furrowing depth and improves the sowing efficiency.

[0018] By controlling the motor to drive the spiral plate to rotate, the seeds in the inverted conical box fall into the gap of the spiral plate under the action of gravity. When the spiral plate rotates, it orderly carries an appropriate amount of garlic seeds to the end of the arc-shaped guide plate and falls to the surface of the slope block. They slide down to the second feeding port under the action of gravity and finally fall into the prepared groove. This avoids seed blockage and ensures uniform and orderly sowing, thus improving the sowing effect. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-4 As shown, this utility model provides a garlic planting device that facilitates adjustment of furrow depth, including a crossbeam 1 and a controller 13. Rollers 4 are rotatably connected to both ends of the crossbeam 1. A column 3 is fixedly connected to the middle of the upper surface of the crossbeam 1. A connecting plate 5 is rotatably connected to the upper end of the column 3. A furrowing wheel 6 is rotatably connected to the other end of the connecting plate 5. A drive assembly for driving the furrowing wheel 6 to rotate is provided on the connecting plate 5. An adjustment assembly 7 for driving the connecting plate 5 to rotate up and down is provided on the crossbeam 1. A planting box 8 is fixedly connected to the middle of the crossbeam 1. A dredging and conveying component 9 is provided inside the planting box 8 to avoid blockage.

[0028] As an optional implementation, a plurality of breaking teeth 601 are fixedly connected to the circumferential surface of the trenching wheel 6, and the two adjacent breaking teeth 601 are staggered in a figure-eight shape. The plurality of breaking teeth 601 arranged in this way can effectively break the soil.

[0029] Reference Figure 2 As shown, the drive assembly includes a sprocket 501 rotatably connected to the connecting plate 5. A sprocket 502 is fixedly connected to the middle shaft of the trenching wheel 6 on the other side of the connecting plate 5. The sprocket 502 and the sprocket 501 are connected by a chain 503. A motor 504 for driving the sprocket 501 to rotate is fixedly installed on the connecting plate 5. The input end of the motor 504 is electrically connected to the output end of the controller 13. By controlling the motor 504 to drive the sprocket 501 to rotate, the sprocket 501 drives the sprocket 502 to rotate through the chain 503, and at the same time drives the trenching wheel 6 to rotate, which facilitates soil breaking and trenching.

[0030] Specifically, the diameter of sprocket 1 501 is smaller than that of sprocket 2 502. Sprocket 1 501 serves as the power point, while sprocket 2 502 serves as the resistance point. By amplifying the output torque through the radius ratio, the input force requirement can be significantly reduced under the same power, thereby achieving the high torque soil breaking and trenching effect of trenching wheel 6.

[0031] Reference Figure 3As shown, the adjusting assembly 7 includes a movable block 701 that moves on the crossbeam 1. A linkage rod 702 connects the movable block 701 to the bottom surface of the connecting plate 5. Both ends of the linkage rod 702 are connected to the movable block 701 and the connecting plate 5 respectively via hinge seats. A slide groove 706 is provided on the crossbeam 1 to slide with the movable block 701. Both the movable block 701 and the slide groove 706 have T-shaped cross sections. A threaded rod 703 is rotatably connected in the slide groove 706. A threaded hole 704 is provided through the movable block 701 to threadedly connect with the threaded rod 703. The crossbeam 1 is fixedly mounted with... A second motor 705 is used to drive the threaded rod 703 to rotate. The input end of the second motor 705 is electrically connected to the output end of the controller 13. The control motor 705 drives the threaded rod 703 to rotate. It is threadedly connected to the movable block 701, thereby moving the lower end of the linkage rod 702. The linkage rod 702 drives the connecting plate 5 to rotate and move downwards gradually. During the downward movement, the rotating trenching wheel 6 opens a pit in the ground. Conversely, the linkage rod 702 can support the connecting plate 5 to rise, so that the trenching wheel 6 is lifted off the ground, thus avoiding wear on the trenching wheel 6 when the device is moved.

[0032] Reference Figure 4 As shown, an inverted conical box 10 is fixedly connected to the upper end of the seeding box 8, and an inclined guide plate 14 is fixedly connected to the bottom of the inverted conical box 10. The lower end of the inclined guide plate 14 matches the lower opening of the inverted conical box 10 to form a first discharge port. An arc-shaped guide plate 15 adapted to the first discharge port is fixedly connected to the upper end of the seeding box 8, and the unblocking conveyor 9 is located above the arc-shaped guide plate 15. The bottom of the seeding box 8 is a slope block 16 adapted to the end of the arc-shaped guide plate 15. The lower end of the seeding box 8 is matched with the lower opening to form a second feeding port. The seeding box 8 and the furrowing wheel 6 are on the same straight line. The control motor 903 drives the spiral plate 902 to rotate. The seeds in the inverted cone box 10 fall into the gap of the spiral plate 902 under the action of gravity. When the spiral plate 902 rotates, it orderly carries an appropriate amount of garlic seeds to the end of the arc-shaped guide plate 15 and drops them onto the surface of the slope block 16. They slide down to the second feeding port under the action of gravity and finally fall into the opened furrow.

[0033] As an optional implementation, the unblocking conveyor 9 includes a rotating shaft 901 rotatably connected to the seed box 8. A spiral plate 902 is fixedly connected to the rotating shaft 901. The diameter of the spiral plate 902 is adapted to the arc-shaped guide plate 15. A motor 903 for driving the rotating shaft 901 to rotate is fixedly installed on the side wall of the seed box 8. The input end of the motor 903 is electrically connected to the output end of the controller 13. The lower side of the spiral plate 902 is arc-shaped and adapted to the arc-shaped guide plate 15, which can prevent seeds from leaking out of the gap between the two and ensure uniform seed delivery.

[0034] Furthermore, batteries 12 are fixedly installed on both sides of the upper surface of the crossbeam 1. The motor 1 504, motor 2 705, motor 3 903 and controller 13 of this application are all powered by batteries 12.

[0035] Specifically, a V-shaped frame 2 is fixedly connected to the front side of the crossbeam 1, and a mounting hook 11 is fixedly connected to the front end of the V-shaped frame 2. The mounting hook 11 allows the device to dock with an agricultural vehicle.

[0036] First, the mounting hook 11 is connected to the agricultural vehicle. Then, the controller 13 controls the motor 504 to drive the furrowing wheel 6 to rotate. Subsequently, the controller 705 drives the threaded rod 703 to rotate. The moving block 701 is threadedly connected to it, thereby moving the lower end of the linkage rod 702. The linkage rod 702 drives the connecting plate 5 to rotate and move downwards gradually. During the downward movement, the rotating furrowing wheel 6 creates a pit in the ground. The controller controls the movement of the agricultural vehicle. The rotating furrowing wheel 6 can create a trench in the ground. Then, the controller 903 drives the spiral plate 902 to rotate. The seeds in the inverted cone box 10 fall into the gap of the spiral plate 902 under the action of gravity. When the spiral plate 902 rotates, it orderly carries an appropriate amount of garlic seeds to the end of the arc-shaped guide plate 15 and drops them onto the surface of the slope block 16. They slide down to the second discharge port under gravity and finally fall into the trench.
