[0017] like Figure 1 -5, the present invention provides a grass paving machine, which includes a frame 2 with an armrest 1, front tires 3 arranged at the bottom of the frame 2 and on both sides of the front end, a drive shaft 4 arranged on the frame 2 through a wheel seat and a bearing seat, drive tires 5 arranged on both sides of the drive shaft 4, a drive unit 6 arranged on the frame 2 and the drive shaft 4, a grass inserting unit 7 arranged on the frame 2 and connected to the drive unit 6, a grass laying unit 8 arranged on the frame 2 and placed at the bottom of the grass inserting unit 7 and connected to the drive unit 6, and a grass storage unit 9 arranged at the front end of the frame 2 and placed on the grass inserting unit 7. The grass paving machine places the turf to be laid on the grass storage unit 9, and then pushes the frame 2 through the armrest 1 to make the drive tire 5 drive the drive shaft 4 to rotate, and then the drive shaft 4 drives the drive unit 6 to rotate, so that the grass inserting unit 7 and the grass laying unit 8 connected to the drive unit 6 move. When laying the grass, the grass inserting unit 6 and the grass laying unit 7 make repeated movements in different directions, that is, when the grass inserting unit 7 is extended, the grass laying unit 8 is retracted, and the turf is placed where the grass needs to be laid. At this time, the grass inserting unit 7 is extended so that the upper turf will not fall. Continuing to push forward will extend the grass laying unit 8 and retract the grass inserting unit 7, so that the turf on the grass inserting unit 7 falls onto the grass laying unit 8 by its own gravity, and then the next piece of turf is laid. The repetitive movement is realized to continuously lay the turf in the grass storage unit 9 at the required position.

[0018] The drive unit 6 includes a drive gear 10 mounted on the drive shaft 4, a first shaft 12 with drive teeth 11 mounted on the frame 2 via a fixing plate 15 and a bearing seat 16, a first chain 13 connecting the drive gear 10 and the drive teeth 11, and a first drive tooth 14 mounted on the first shaft 12 and positioned outside the drive tooth 11 for driving the grass inserting unit 7 and the grass laying unit 8. The drive unit 6 is powered by the drive gear 10 mounted on the drive shaft 4. The first chain 13 connects the drive gear 10 and the drive teeth 11, transmitting the power to the first shaft 12. The first drive tooth 14 is then mounted on the first shaft 12 to drive the grass inserting unit 7 and the grass laying unit 8 to perform their respective operations. The drive unit 6 is powered by a purely mechanical structure.

[0019] The grass inserting unit 7 includes a supporting plate 17 arranged at the front and rear ends of the frame 2, a grass inserting screw 20 with a first slider 19 on both sides of the bottom of the two supporting plates 17 arranged through a screw seat 18, a grass inserting board 21 with a fork structure at the front end arranged on the two grass inserting screws 20 and placed on the first slider 19, a fixed bracket 22 arranged on the grass inserting board 21, a moving rod 23 hinged on the fixed bracket 22, and a rocker 24 arranged on the first driving tooth 14 and hinged to the moving rod 23 for providing driving force. The grass inserting unit 7 is arranged on the frame 2 through two front and rear supporting plates 17, and a grass inserting screw rod 20 with a first slider 19 is arranged on the two supporting plates 17, and then the grass inserting board 21 with a fork structure at the front end is installed on the first slider 19, so that the grass inserting board 21 can make a limited forward and backward movement on the grass inserting screw rod 20, and further driven by the rocker 24 set on the first driving tooth 14 to move the moving rod 23, and the moving rod 23 is hinged to the fixed bracket 22 set on the grass inserting board 21, and then the moving rod 23 drives the grass inserting board 21 to move back and forth on the grass inserting screw rod 20, that is, the grass inserting board 21 prevents all grass from falling off.

[0020] The grass-laying unit 8 includes a partition 25 with a U-shaped structure placed on the front and rear sides of the bottom of the frame 2 and connected to the frame 2, a grass-laying screw rod 27 with a second slider 26 arranged on both sides of the bottom of the two partitions 25 through a screw rod seat, a grass-laying board 28 arranged on the grass-laying screw rod 27 and placed on the second slider 26, a connecting rod 30 connecting the grass-laying board 28 in a 7 shape and with a slide groove 29 at the tail, a rocker rod 31 arranged on the connecting rod 30 and placed in the slide groove 29, a grass-laying shaft rod 32 arranged on the frame 2 through a fixing plate 15 and a bearing seat 16, a second driving tooth 33 arranged on the grass-laying shaft rod 32 and with the rocker rod 31 placed thereon, and a second chain 34 connecting the first driving tooth 14 and the second driving tooth 33. The grass laying unit 8 is installed on the frame 2 through two U-shaped partitions 25, and a grass laying wire rod 27 with a second slider 26 is installed on the two partitions 25. The grass laying board 28 is then installed on the second slider 26, so that the grass laying board 28 can move back and forth on the grass laying wire rod 27. The grass laying board 28 is driven to move by connecting the first driving tooth 14 and the second driving tooth 22 through the second chain 34, so that the power is transmitted from the first driving tooth 14 to the second driving tooth 33. Further, the second driving tooth 33 drives the swing rod 31 to move. Since one end of the swing rod 31 is set on the connecting rod 30 The chute 29 is a 308X8mm through groove, and the rocker arm 31 can drive the connecting rod 30 to move back and forth. The connecting rod 30 is connected to the turf laying board 28, so the connecting rod 30 can drive the turf laying board 28 to move back and forth on the turf laying screw rod 27. When laying turf, since there is just enough space between the turf laying board 28 and the turf inserting board 21, the directional reciprocating motion of the turf inserting board 21 and the turf laying board 28 can only allow one turf to be laid at the place where turf is needed. The chute 29 is a 308X8mm through groove, and the rocker arm 31 is placed in the chute 29 through the Seda screw and the bearing.

[0021] The grass storage unit 9 includes a grass receiving plate 35, located at the front end of the frame 2 and placed on the grass inserting unit 7, for carrying grass, and a baffle (not shown) connected to the grass receiving plate 35 for blocking the grass. The grass storage unit 9 stores turf through the cooperation of the grass receiving plate 35 and the baffle. During turf laying, the turf gradually slides onto the grass inserting plate 21 under its own power. When the grass inserting plate 21 is retracted, the turf falls onto the turf laying plate 28. When the turf laying plate 28 is retracted, the turf on it is laid in the desired location.

[0022] The drive unit 6 is a motor or a motor drive. The drive unit 6 can also be a motor drive or a motor drive, which can be selected according to the needs of the customer or the situation of the place of use to meet different needs.

[0023] The calculation method of the paving machine is: the diameter of the driving tire 5 is 350mm, so the circumference of the driving tire 5 is C = πD = 1099mm when the driving tire 5 makes one circle. Most of the common turfs on the market are 200X200mm, so the driving tire 5 makes one circle about the length of five pieces of turf. Therefore, we need to choose a set of driving gears 10 with the same module, a tooth number of 1:5 or a speed ratio of 1:5 to ensure the normal operation of the paving machine. The turf length L = 20cm is known, so the circumference of the driving tire 5 is C = πD = 1099mm≈1m, and the turf length is known. L: The circumference of the driving tire 5 is C=1:5, so the speed ratio of the driving gear 10 and the driving tooth 11 is n1:n3=1:5, and the speed ratio of the first driving tooth 14 and the second driving tooth 33 is n2:n4=1:1. In this way, the driving tire 5 rotates one circle and lays 5 pieces of grass, thereby pushing the grass paving machine to travel an average of 50 meters per minute. The driving tire 5 rotates 50 circles. Through the above calculation, it can be known that the grass paving machine produces 250 pieces of grass, and the upper fork and lower plate (the upper fork is the grass inserting plate, and the lower plate is the grass laying plate) reciprocates a number of times A=250. Therefore, it can be known that the movement speed of the upper fork and lower plate is V=2A / t=8.3m / s.

[0024] Since the maximum turf is 300X300, the maximum stroke needs to be 300. The diameters of the first driving tooth 14 and the second driving tooth 33 are insufficient, so an additional rocker 24 and a rocker arm 31 with a length of 150 are required to meet the stroke.

[0025] The movement principle is that as the driving tire 5 rotates, it drives the driving gear 10; the driving gear 10 is connected to the driving tooth 11; the driving tooth 11 drives the coaxial first driving tooth 14, and the first driving tooth 14 and the second driving tooth 33 rotate together; the first driving tooth 14 is connected to the upper fork, and the second driving tooth 33 is connected to the lower plate. Finally, the first driving tooth 14 and the second driving tooth 33 continue to rotate, causing the upper fork and the lower plate to do reciprocating motion, such as Figure 5 A motion diagram is shown.

[0026] This type of grass paving machine can replace pure manual grass paving, reduce the labor intensity of workers and improve work efficiency. The grass paving machine has a simple structure and cleverly uses chain transmission, crank rocker, etc. to achieve mechanical grass paving. In addition, this type of grass paving machine has a light appearance, occupies a small area and is easy to store. The grass paving machine can be used in community gardens, courtyards, flower beds, etc., and can also be used for lawn protection planting on slopes, dams, roads, and railway slopes. The simple and small grass paving machine can reduce the labor for grass paving and improve work efficiency.
