Description

Technical Field

[0001] This application relates to the field of desertification control equipment technology, and in particular to a novel double-row sand compactor. Background Technology

[0002] In desertification control projects, sand stabilization and afforestation are key technical means to curb the spread of desertification. Its core principle is to lay straw and compact the sand to form sand barriers that prevent wind erosion and stabilize the sand, creating a stable environment for vegetation growth. Currently, double-row sand stabilization equipment on the market generally suffers from poor adaptability between straw feeding and sand stabilization operations. In particular, when adjusting operating parameters to meet the needs of sand barriers of different widths, it is difficult to balance the adjustment accuracy and operating efficiency of the equipment. The feeding mechanism of existing sand compactors is mostly designed with a fixed spacing. When it is necessary to adjust the spacing of the double-row sand barriers according to the degree of desertification and the difference in vegetation species in the treatment area, it is necessary to manually disassemble and reinstall the feeding components. This is not only cumbersome, time-consuming and labor-intensive, but also difficult to guarantee the coaxiality and spacing accuracy of the feeding mechanism after reassembly. This results in uneven spreading of grass, with excessive grass accumulation in some areas causing waste, and insufficient grass in some areas affecting the stability of the sand barriers.

[0003] To address this issue, a novel double-row sand press machine has been invented to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to overcome the technical defects of existing double-row sand presses, such as cumbersome adjustment of the material feeding distance and poor adaptability of the sand pressing height, and to provide a new type of double-row sand press that can achieve precise adjustment of the material feeding distance, flexible adaptation of the sand pressing height, and ensure continuous operation and efficiency.

[0005] This application provides a novel double-row sand press, which adopts the following technical solution: including a mounting frame, a feeding mechanism, an adjusting mechanism, a sand pressing mechanism, and a lifting assembly; The unloading mechanism is provided on both sides of the mounting frame, and the sand pressing mechanism is provided on the front side of the unloading mechanism; The adjustment mechanism is mounted on the mounting frame and is used to drive the distance between the two feeding mechanisms to change. The lifting assembly is mounted on the mounting frame and is used to adjust the height of the sand pressing mechanism.

[0006] Optionally, the feeding mechanism includes a hopper, a sliding frame, a sliding rod, a discharge hook, a feeding motor, a rotating disk, and a hinge rod; The bottom of the hopper is provided with a discharge trough. The sliding frame is slidably disposed at the bottom of the hopper. Multiple sliding rods are provided and evenly distributed on the sliding frame. Multiple discharge hooks are provided and distributed on the sliding rods. When the sliding frame drives the sliding rods to slide, it drives the discharge hooks to hook the grass out of the discharge trough. The feeding motor is located at the bottom of the hopper, the rotating disk is connected to the output end of the feeding motor, one end of the hinge rod is eccentrically hinged to the rotating disk, and the other end is hinged to the sliding frame.

[0007] Optionally, the adjustment mechanism includes a bidirectional screw, a connecting plate, and a first motor; The bidirectional screw is rotatably mounted on the mounting frame, and the connecting plates are fixed to the rear sides of the two feeding mechanisms respectively. The two connecting plates are located on both sides of the bidirectional screw and are threadedly connected to it. The first motor is mounted on the mounting frame, and its output end is connected to a bidirectional screw drive.

[0008] Optionally, the sand pressing mechanism includes a mounting frame, a sand pressing disc, a drive shaft, a third motor, a drive rod, and a drive cylinder; The mounting frame is slidably connected to the front side of the hopper, the drive shaft is rotatably mounted on the mounting frame, the third motor is mounted on the mounting frame and its output end is connected to the drive shaft, and the sand pressing disc is mounted on the drive shaft. The transmission rod is fixed to the end of one of the transmission shafts, and the transmission cylinder is fixed to the end of the other transmission shaft. The transmission rod and the transmission cylinder are slidably connected.

[0009] Optionally, the lifting assembly includes a sliding frame, a vertical screw, and a second motor; The vertical screw is rotatably mounted on the mounting frame, and the second motor is mounted on the mounting frame with its output end connected to the vertical screw; The sliding frame is slidably connected to the mounting frame and threadedly connected to the vertical screw, and the sliding frame is slidably connected to the mounting frame of the sand pressing mechanism.

[0010] In summary, this application includes the following beneficial technical effects: 1. Precise and efficient spacing adjustment: Through the cooperation of the bidirectional screw of the adjustment mechanism and the connecting plate, the two feeding mechanisms can slide synchronously in opposite directions under the drive of the first motor. The spacing can be adjusted steplessly without disassembly, which greatly improves the work efficiency and sand barrier laying accuracy.

[0011] 2. Adaptive sand compaction height: The lifting component drives the sliding frame to rise and fall through a vertical screw, which in turn drives the sand compaction mechanism to adjust its height in real time according to the undulations of the desert surface, ensuring that the sand compaction degree is uniform in different terrain areas and avoiding the problems of waste of straw and insufficient compaction.

[0012] 3. Material feeding and sand pressing are coordinated and adapted: The feeding mechanism is driven by the feeding motor to feed the material precisely. With the adjustable spacing and sand pressing height, it realizes the integrated operation of "precise feeding and sand pressing". Attached Figure Description

[0015] Reference Figure 1 , Figure 4One embodiment shown is as follows: The novel double-row sand press includes a mounting frame 1, a feeding mechanism 2, an adjusting mechanism 3, a sand pressing mechanism 4, and a lifting assembly 5. In this embodiment, the mounting frame 1 is a horizontally arranged frame structure, and the feeding mechanism 2 is slidably mounted on its left and right sides via slide rails. The feeding mechanism 2 extends along the length of the mounting frame 1. The sand pressing mechanism 4 is connected to the front side of the feeding mechanism 2 away from the center of the mounting frame 1 via a sliding connector. The adjusting mechanism 3 is horizontally mounted at the top center of the mounting frame 1, and its two ends are respectively connected to the rear sides of the two feeding mechanisms 2. The lifting assembly 5 is vertically mounted at both ends of the front side of the mounting frame 1, and its output end is slidably connected to the end of the sand pressing mechanism 4.

[0016] The implementation principle is as follows: the mounting frame 1 provides a bearing base for each component, and the feeding mechanism 2 is slidably connected to the frame through the slide rail, ensuring the stability of the feeding mechanism 2 during adjustment; the sand compaction mechanism 4 is connected to the front side of the feeding mechanism 2, ensuring that the forage can be compacted immediately after feeding, reducing the operation interval; the adjustment mechanism 3 is assembled in the center of the frame and connected to the feeding mechanism 2, and can realize the synchronous adjustment of the feeding mechanisms 2 on both sides through centralized drive; the lifting component 5 is vertically assembled in the front side of the frame and connected to the sand compaction mechanism 4, which can accurately control the height change of the sand compaction mechanism 4 to adapt to different operation requirements.

[0017] Reference Figure 2 , Figure 5 , Figure 6 One embodiment shown is as follows: The feeding mechanism 2 includes a hopper 6, a sliding frame 7, sliding rods 8, a discharge hook 9, a feeding motor 10, a rotating disk 11, and a hinge rod 12. In this embodiment, the hopper 6 has a cuboid structure with an open top, and a long strip-shaped discharge trough 13 is provided at its bottom along its length. The width of the discharge trough 13 is adapted to the feeding requirements of the forage. The sliding frame 7 is slidably mounted on the bottom of the hopper 6 and can slide back and forth along the bottom of the hopper 6. Multiple sliding rods 8 are provided, and the multiple sliding rods 8 are evenly spaced and fixed on the sliding frame 7. Multiple discharge hooks 9 are provided. Each sliding rod 8 is welded with at least two discharge hooks 9 at intervals, with the bent end of the discharge hook 9 facing the discharge end of the discharge trough 13; the feeding motor 10 is fixedly mounted on the bottom of the hopper 6 away from the adjusting mechanism 3 by a motor bracket, and its output shaft is set horizontally and facing the center of the hopper 6; the rotating disk 11 has a circular plate structure, and its center position is fixed to the end of the output shaft of the feeding motor 10 by a key connection; one end of the hinge rod 12 is eccentrically hinged to the edge of the rotating disk 11 away from the center by a pin, and the other end is hinged to the end of the sliding frame 7 by a pin.

[0018] The implementation principle is as follows: the hopper 6 stores the forage, and the bottom discharge trough 13 provides a channel for the forage output; the discharge motor 10 drives the rotating disk 11 to rotate. Because the hinge rod 12 is eccentrically connected to the rotating disk 11, the rotational motion of the rotating disk 11 is converted into the reciprocating swing of the hinge rod 12; the hinge rod 12 drives the sliding frame 7 to slide along the chute at the bottom of the hopper 6, and the sliding frame 7 synchronously drives the sliding rod 8 and the discharge hook 9 on it to move; when the discharge hook 9 moves with the sliding rod 8, it can extend into the discharge trough 13 to hook out the forage, so as to realize the uniform and quantitative conveying of the forage. The uniform distribution of the sliding rod 8 ensures the consistency of the discharge.

[0019] Reference Figure 5 , Figure 7 One embodiment shown is as follows: The adjusting mechanism 3 includes a bidirectional screw 14, a connecting plate 15, and a first motor 16. In this embodiment, the bidirectional screw 14 is horizontally arranged along the width direction of the mounting frame 1, and its two ends are rotatably mounted on the two side supports on the top of the mounting frame 1 via bearing seats. The bearing seats and the supports are fixedly connected by bolts to ensure the stability of the bidirectional screw 14 when rotating. The two sides of the bidirectional screw 14 are provided with threaded sections with opposite directions of rotation, and the lengths of the threaded sections on both sides are equal. The connecting plate 15 is L-shaped. The structure is plate-shaped. Each of the two feeding mechanisms 2 has a connecting plate 15 welded to its rear end. The vertical section of the connecting plate 15 is fixed to the feeding mechanism 2, and the horizontal section extends toward the bidirectional screw 14. The center of the horizontal section has a threaded hole that matches the thread of the bidirectional screw 14. The two connecting plates 15 are threadedly connected to the threaded sections on both sides of the bidirectional screw 14 through the threaded holes. The first motor 16 is fixedly mounted on the top of the mounting frame 1 near one of the bearing seats through a motor base. Its output shaft is connected to the end of the bidirectional screw 14 through a coupling. The two ends of the coupling are fixed to the output shaft of the first motor 16 and the bidirectional screw 14 through key connections.

[0020] The implementation principle is as follows: After the first motor 16 starts, it drives the bidirectional screw 14 to rotate around its own axis through the coupling. Since the threads on both sides of the bidirectional screw 14 turn in opposite directions and the two connecting plates 15 are respectively threaded to the threaded sections on both sides, the rotational motion of the bidirectional screw 14 is converted into the synchronous reverse sliding of the two connecting plates 15 along the length direction of the bidirectional screw 14. The connecting plates 15 drive the feeding mechanism 2 fixed to them to move along the slide rails on both sides of the mounting frame 1, thereby realizing the precise adjustment of the distance between the two feeding mechanisms 2.

[0021] Reference Figure 1One embodiment shown is as follows: The sand-pressing mechanism 4 includes a mounting frame 17, a sand-pressing disc 18, a drive shaft 19, a third motor 20, a drive rod 21, and a drive cylinder 22. In this embodiment, the mounting frame 17 is slidably connected to the slide rail on the front side of the feeding mechanism 2 via a slider, and the slider can slide up and down along the slide rail; the drive shaft 19 is arranged horizontally and parallel to the length direction of the feeding mechanism 2, and its two ends are rotatably mounted on the vertical rods on both sides of the mounting frame 17 via bearings; the third motor 20 is fixedly mounted on the outside of the vertical rod on one side of the mounting frame 17 via a motor bracket, and its output shaft is connected to the end of the drive shaft 19 via a key. The system is fixed to achieve power transmission. The sand pressing disc 18 has a disc-shaped structure with a slot at its edge and is fixed to the transmission shaft 19. The edge of the sand pressing disc 18 is adapted to the ground. The transmission rod 21 has a cylindrical rod-shaped structure, and one end of it is fixed by welding to the end of one of the transmission shafts 19 away from the third motor 20. The transmission cylinder 22 has a cylindrical structure with open ends. Its inner diameter is adapted to the outer diameter of the transmission rod 21. One end of the transmission cylinder 22 is fixed by welding to the end of another transmission shaft 19 away from the third motor 20. The end of the transmission rod 21 away from the transmission shaft 19 is slidably inserted into the transmission cylinder 22 to form a sliding fit.

[0022] The implementation principle is as follows: the third motor 20 drives the transmission shaft 19 to rotate, and the transmission shaft 19 drives the sand pressing plate 18 on it to rotate synchronously. The sand pressing plate 18 contacts the ground to compact the sand. The mounting frame 17 is slidably connected to the feeding mechanism 2 through the slider, providing support for the lifting and lowering of the sand pressing mechanism 4. When the adjusting mechanism 3 changes the distance between the two feeding mechanisms 2, the transmission shaft 19 on one side drives the transmission rod 21 to slide along the transmission cylinder 22, ensuring that the transmission shafts 19 on both sides can rotate synchronously while adapting to the change in distance, ensuring the continuity and stability of the sand pressing operation.

[0023] Reference Figure 3 , Figure 4 One embodiment shown is as follows: The lifting assembly 5 includes a sliding frame 23, a vertical screw 24, and a second motor 25. In this embodiment, the vertical screw 24 is arranged vertically, and its upper and lower ends are rotatably mounted on the columns at both ends of the front side of the mounting frame 1 through bearing seats. The bearing seats and columns are fixed by bolts. The second motor 25 is fixedly mounted on the top of the mounting frame 1 through a motor seat, and its output shaft is fixedly connected to the top end of the vertical screw 24. The sliding frame 23 has a threaded hole that matches the thread of the vertical screw 24, and is threadedly connected to the vertical screw 24 through the threaded hole. The inner side of the vertical section of the sliding frame 23 has a sliding groove. The sand pressing mechanism 4 mounting frame 17 is slidably mounted on the sliding frame 23 to achieve a relative sliding connection between the two in the horizontal direction.

[0024] The implementation principle is as follows: After the second motor 25 starts, it drives the vertical screw 24 to rotate around its own axis; since the sliding frame 23 is threadedly connected to the vertical screw 24, the rotational motion of the vertical screw 24 is converted into the lifting motion of the sliding frame 23 in the vertical direction; the sliding frame 23 cooperates with the slider of the sand pressing mechanism 4 mounting frame 17 through the sliding groove, driving the mounting frame 17 and the entire sand pressing mechanism 4 to lift synchronously, thereby realizing the flexible adjustment of the sand pressing height to adapt to different surface conditions.

[0025] The working principle of this device is as follows: Before operation, the adjustment mechanism 3 is activated according to the required spacing of the sand barrier: the first motor 16 drives the bidirectional screw 14 to rotate through the coupling. Since the threads on both sides of the screw rotate in opposite directions, the two connecting plates 15 connected to the screw threads drive the feeding mechanism 2 to slide synchronously in the opposite direction along the frame slide rail until the preset spacing is reached.

[0026] Then the feeding mechanism 2 is started: the feeding motor 10 drives the rotating disk 11 to rotate, and the eccentric hinge rod 12 converts the rotational motion into reciprocating swing, pulling the sliding frame 7 to slide along the bottom of the hopper 6. The discharge hook 9 on the sliding rod 8 moves as a whole, extending into the discharge trough 13 to hook out the straw evenly, completing the double-row straw laying.

[0027] Meanwhile, the lifting assembly 5 adjusts the sand-pressing height according to the ground conditions: the second motor 25 drives the vertical screw 24 to rotate, and the sliding frame 23, which is threadedly connected to the screw, moves up and down along the frame, and drives the mounting frame 17 of the sand-pressing mechanism 4 to move synchronously through the sliding groove.

[0028] When the sand pressing mechanism 4 is working, the third motor 20 drives the transmission shaft 19 to rotate, and the transmission shaft 19 drives the sand pressing plate 18 to rotate and compact the sand. When the spacing is adjusted, the transmission rod 21 of the transmission shaft 19 on one side slides along the transmission cylinder 22 on the other side to ensure that the sand pressing plates 18 on both sides work synchronously and realize the coordinated operation of material feeding and sand pressing.

[0029] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
