A horizontal planting device for grass squares

Abstract

This utility model belongs to the field of agricultural machinery technology and discloses a horizontal grass checkerboard planting device, specifically relating to the technology of grass checkerboard laying in desert areas. The horizontal grass checkerboard planting device includes two sets of grass feeding devices, one set of grass releasing devices, two sets of grass planting devices, a transmission system, and a frame. The feeding devices segment the grass rolls and lay them on the turning platform of the grass releasing device. The grass releasing device, through the turning motion of the turning platform, vertically drops the grass mat from the gap between the baffle and the turning platform into the wedge-shaped grass hopper in the grass planting device, which is composed of a front fixed plate and a rear moving plate. The wedge-shaped grass hopper is pressed into the ground by the rotation of a triangular turntable. During the rotation of the rear moving plate, the relative movement of the sliding rods at both ends within the cam grooves of the triangular turntables on both sides achieves the opening and closing of the front fixed plate and the rear moving plate, completing the grass pulling and planting. When the grass hopper reaches the lowest point, the front fixed plate and the rear moving plate separate, leaving the grass mat in the sand, thus realizing the horizontal grass checkerboard planting process.

Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a grass grid horizontal planting device. Background Technology

[0002] To prevent sandstorms, the common method currently used is to lay straw checkerboard mats. Most existing straw checkerboard mat laying devices use a unidirectional laying method, which leads to problems such as straw pressing and overlapping work paths, affecting the laying effect. Traditional laying methods involve laying the straw mats flat on the ground and pressing them into the sand with a knife, resulting in significant straw consumption. This invention designs a novel horizontal straw checkerboard mat planting device that can automatically plant straw mats in sections along the horizontal direction, providing a new approach to horizontal straw checkerboard mat laying while reducing straw consumption. Summary of the Invention

[0003] The purpose of this utility model is to provide a grass checkerboard horizontal planting device, which provides a grass checkerboard laying device for sandy land that can plant grass rolls in sections during the process of moving.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: refer to Figure 1 A grass grid horizontal planting equipment mainly includes a set of conveying devices, a set of horizontal grass dispensing devices, two sets of horizontal grass planting devices and a transmission system. The grass feeding device (1), grass dispensing device (2) and grass planting device (3) are installed on the frame (5) from top to bottom to form a continuous operation structure for conveying, guiding and burying grass curtains from top to bottom.

[0020] refer to Figure 2 The grass feeding device (1) consists of a grass roll (11), a traction roller (12), a guide roller (13), a guide gear (14), a fixed blade (15), a guide rail (16), and a moving blade (17). The two shaft ends of the grass roll (11) are placed in the U-shaped groove of the frame (5). The traction roller (12) and the guide roller (13) are mounted on the frame (5) and rotate relative to each other through the gear (14). The fixed blade (15) is fixed to the end of the frame (5) with the blade facing the grass roll direction. Two sets of guide rails (16) are distributed on the left and right sides of the fixed blade and fixed to the frame (5). The moving blade (17) is mounted on the guide rails (16) on the left and right sides and can move horizontally along the direction of the guide rails (16). The two sets of grass feeding devices are symmetrically installed with respect to the symmetrical center plane of the frame (5).

[0021] refer to Figure 3 The grass feeding device (2) consists of a turning table (21), a turning table drive shaft (22), a grooved wheel (23), a turntable (24), a limit wheel (25), a baffle (26), and a limit spring (27). The left and right sides of the turning table (21) are fixedly connected to two turning table drive shafts (22) respectively. The outer shaft ends of the grooved wheel (23) and the turntable (24) are connected to the frame (5). The grooved wheel (23) is fixedly connected to the turning table drive shaft (22) and forms a Geneva mechanism with the turntable (24), intermittently feeding grass. The rotating device provides torque. For every rotation of the turntable (24), the grooved wheel (23) drives the tilting table to rotate 90°. The limit wheel (25) is installed at the four corners on the left and right sides of the tilting table (21) through the bearing seat. The limit wheel (25) near the baffle (26) is always tangent to the plane of the baffle (26) to provide a falling channel for the grass. The other side of the baffle (26) is connected to the frame (5) through the limit spring (27). The baffle (26) is self-adaptively limited by the compression and reset of the limit spring (27).

[0022] refer to Figure 4During the operation of the grass feeding device (1), the traction roller (12) and the guide roller (13) rotate relative to each other through gear transmission. The traction roller (12) pulls the grass curtain from the grass roll (11) with radius R to the middle of the traction roller (12) with radius r1 and the guide roller (13) with radius r2. After the grass curtain is compacted through the gap between the traction roller (12) and the guide roller (13), it is conveyed obliquely downward through the inside of the fixed blade (15) and the moving blade (17). The grass curtain and the plane above the turning table (21) are at an angle of β, and the grass curtain contacts the plane above the turning table (21). The front grass curtain is pushed by the continuous conveying of the grass curtain, so that the grass curtain is laid flat on the upper side of the turning table (21). When the grass curtain is fully covered on the upper side of the turning table (21), the moving blade (17) moves along the guide rail direction. When it contacts the grass curtain, it provides the blade movement direction and the horizontal shearing force perpendicular to it. It intersects with the fixed blade (15) to complete the shearing process of the grass curtain.

[0023] refer to Figure 5 During the operation of the grass-laying device (2), when the shearing device completes the lateral shearing of the grass curtain, the grooved wheel (23) drives the turning table (21) to rotate toward the baffle (26). During rotation, the limiting wheel (25) is always tangent to the side of the baffle (26). When the rotation angle of the turning table is less than 45°, the limiting wheel (25) pushes the baffle (26) away from the turning table (21), and the limiting spring (27) is compressed. When the rotation angle of the turning table is greater than 45°, the limiting spring (27) pushes the baffle (26) closer to the turning table (21), maintaining the tangent relationship between the baffle and the limiting wheel. During this stage, the grass curtain falls freely into the planting device through the gap formed between the turning table (21) and the baffle (26).

[0024] refer to Figure 6 , Figure 7The grass planting device consists of a triangular turntable (31), a triangular turntable drive shaft (32), an eccentric disc (33), support wheels (34), an eccentric rod (35), a grass bucket mounting frame (36), a front fixed plate (37), a rear movable plate (38), and a sliding rod (39). The center of the triangular turntable (31) is connected to the frame (5) through the triangular turntable drive shaft (32) and rotates around the axis O1-O1'. The eccentric disc (33) rotates around the axis O2-O2', which is d away from the axis O1-O1' and is on the same horizontal plane. It is connected to the frame through three tangent support wheels (34) on the inner ring and evenly distributed along the inner ring. One end of the eccentric rod (35) is connected to the through holes A1, A2, and A3 evenly distributed around the circumference of the triangular turntable (31) with O1 as the center and R1 as the radius. The other end is connected to the through holes B1, B2, and B3 evenly distributed on the circumference of the eccentric disc (33) with O2 as the center and R1 as the radius, forming an eccentric feeding structure; the front fixed plate (37) is fixedly connected to the inner side of the front end of the grass bucket mounting frame (36), and the rear moving plate (38) is installed on the inner side of the rear end of the grass bucket mounting frame (36), which can move vertically along the inner wall of the grass bucket mounting frame (36). One end of the sliding rod (39) is fixedly connected to the top of the rear moving plate (38), and the other end extends into the guide groove next to the through holes A1, A2, and A3 on the triangular turntable (31), which can move inside the guide groove, forming a pull-out grass bucket structure; the three sets of pull-out grass bucket structures pass through the through holes A1, A2, and A3 on the triangular turntable (31) and are fixedly connected to the eccentric rod (35), so that the three sets of pull-out grass bucket devices always remain vertically downward.

[0025] refer to Figure 8 During the operation of the grass planting device (3), the triangular turntable (31) rotates in the same direction as the equipment's forward direction, so that when the grass bucket mounting frame (36) reaches its lowest point, its horizontal velocity relative to the ground is 0, the front fixed plate (37) is fixed relative to the grass bucket mounting frame (36), and the rear moving plate (38) moves with the sliding rod (39) in the guide groove on the triangular turntable (31) to achieve a change in position relative to the front fixed plate (37) in the vertical direction; when the grass bucket mounting frame (36) reaches point p1, the sliding rod (39) is located at the lowest point in the guide groove, and the rear moving plate (38) and the front fixed plate (37) are in a closed state. (36) When the slide bar (39) reaches point p2, it begins to rise, and the rear moving plate (38) and the front fixed plate (37) begin to open. When the grass bucket mounting frame (36) reaches point p3, the slide bar (39) is at the highest point in the guide groove, and the rear moving plate (38) and the front fixed plate (37) are at their largest opening, leaving the grass curtain in the sand. When the grass bucket mounting frame (36) reaches point p4, the slide bar (39) begins to fall, and the rear moving plate (38) and the front fixed plate (37) begin to close. When the grass bucket mounting frame (36) reaches point p5, the rear moving plate (38) and the front fixed plate (37) are completely closed, and grass is collected to carry out the next cycle of horizontal grass planting operation.

[0026] refer to Figure 9 The transmission system (4) consists of a transmission belt (41), a driving pulley (42), and a driven pulley (43). The driving pulley (42) is fixed to the drive shaft (32) of the triangular turntable, and the driven pulley (43) is fixed to the shaft of the turntable (24). The two pulleys are driven by the transmission belt (41). The diameter ratio of the driving pulley (42) to the driven pulley (43) is 3:1, so that when the planting device completes one planting operation, the turning device also completes one turning and grass-releasing operation.
