It aims to meet the various spatial and place requirements of people's outdoor activities. Through site analysis, function integration and research on relevant social, economic and cultural factors, a comfortable and beautiful outdoor living environment is created through overall design, and people are given spiritual and aesthetic pleasures. When designing and planning landscape gardening, it is necessary to demarcate the areas of landscape gardening by drawing lines. In the prior art, lime powder is generally manually spread for line drawing, and there are also corresponding line drawing devices with the progress of technology.

A line drawing device for landscape gardening design includes a box body. There is a feed hopper at the front end of the upper surface of the box body. The lower surface of the box body is triangularly structured with a plurality of wheels. There is a rotating shaft at the lower side of the rear end of the box body. The rotating shaft is rotatably connected with two support blocks in a left-right symmetric structure. An installation box is sleeved in the middle of the rotating shaft. A bevel gear A is arranged inside the installation box. The bevel gear A is meshed with a bevel gear B. A rotating rod is sleeved in the middle of the bevel gear B. The front end of the rotating rod passes through the inner wall of the installation box and extends to the outer wall and is welded with an auger. When the wheels of the present utility model drive the bevel gear A to rotate, the bevel gear B, the rotating rod and the auger move synchronously. The auger pushes the lime powder out of the round tube. The rotation speed of the auger is proportional to the rotation speed of the wheels, which is convenient to control the discharge amount of the lime powder, the line drawing is more uniform, and the display effect is good.

[0004] The prior art has the following deficiencies: The existing line drawing device is used with lime powder filled, but it is not applicable to the lumpy lime raw materials.

[0042] The bottom of the second box body 7 is funnel-shaped, a rolling hollow hammer 24 is arranged in the second box body 7, a plurality of telescopic rolling pipes 28 are installed on the circumferential side surface of the rolling hollow hammer 24, the bottom surface of the rolling hollow hammer 24 is adapted to the inner surface of the bottom of the second box body 7, a plurality of rolling heads 29 are installed on the bottom surface of the rolling hollow hammer 24, the center of the top surface of the rolling hollow hammer 24 is fixedly installed with a square pipe 30, a square shaft 31 is slidably installed at the top of the square pipe 30, the top end of the square shaft 31 is connected to the driving shaft of the third motor 18, the third motor 18 is installed on the top surface of the second box body 7, the top surface of the rolling hollow hammer 24 is fixedly installed with an annular slide rail 26 through a plurality of support rods, a plurality of electric push rods 25 are installed on the top surface of the second box body 7, the telescopic ends of the electric push rods 25 extend downward into the annular slide rail 26 and are installed with sliders 27, and the sliders 27 are slidably arranged in the annular slide rail 26; the top surface and the bottom surface of the rolling hollow hammer 24 are both conical slopes.

[0043] A thin elbow 13 is rotatably installed at the bottom of the second box body 7, an adjusting assembly 14 is installed at the connection between the top of the base 1 and the second box body 7 and the thin elbow 13, and a lime discharge port is arranged at the bottom end of the thin elbow 13.

[0044] After the lime is preliminarily crushed in the first box body 6, it enters the arc-shaped elbow 9 from the bottom of the first box body 6 in sequence, and then is ready to enter the conveying pipe 10. Under the rotation cooperation of the spiral blade 23 arranged in the conveying pipe 10, it can be conveyed from the conveying pipe 10 to the second box body 7. A rolling empty hammer 24 is arranged in the second box body 7. The conical slope on the top of the rolling empty hammer 24 facilitates the lime to fall to the circumferential side and the bottom position of the rolling empty hammer 24, so as to cooperate with the inner wall of the second box body 7 for rolling and crushing. The third motor 18 drives the rolling empty hammer 24 to rotate in the second box body 7. At the same time, the electric push rod 25 controls the annular slide rail 26 to connect the rolling empty hammer 24 to lift up and down repeatedly in the second box body 7, so as to crush the lime falling to the bottom of the second box body 7 and between the circumferential side of the crushing empty hammer 24. Then, the lime after secondary crushing can enter the inside of the thin elbow 13 from the discharge hopper 71, and finally be discharged from the lime discharge port of the thin elbow 13. By adjusting the position of the thin elbow 13 through the adjusting assembly 14, the scribing operation can be carried out.

[0045] Furthermore, the bottom of the rotating shaft 19 penetrates below the second screen 34 and is provided with a fixing sleeve 32. The fixing sleeve 32 is detachably installed with the bottom of the rotating shaft 19 through a locking bolt 37. A plurality of rubber strips 33 are installed at the bottom of the fixing sleeve 32.

The lower ends of the inclined struts 38 are fixed with a scraper 22. The scraper 22 is in frictional contact with the inner bottom wall of the first box body 6 and the top surface of the second screen 34. When the rotating shaft 19 rotates, it drives the inclined struts 38 and the scraper 22 at the bottom to rotate. The installation angle of the scraper 22 enables it to fully contact the inner bottom wall of the first box body 6, so as to scrape off the residual lime powder on the surface and make it more convenient and thorough to discharge into the inside of the arc-shaped elbow 9.

[0048] Furthermore, the cross section of the annular guide rail 26 is in a "concave" shape structure. The central dimension of its cross section matches the diameter of the slider 27, and the opening dimension of the top surface of its cross section is smaller than the diameter of the slider 27 and larger than the diameter of the telescopic end of the electric push rod 25.

One end of the sleeve 281 is slidably installed with a tapered rod 282. One end of the tapered rod 282 slidably penetrates to the outside of the rolling hollow hammer 24. The other end of the tapered rod 282 is located inside the sleeve 281 and is installed with a limiting piece 284 and a spring 283. The end of the sleeve 281 and the circumferential side surface of the rolling hollow hammer 24 are both provided with sliding holes having the same aperture. The diameter of the limiting piece 284 is larger than the diameter of the sliding hole.

[0051] After the lime enters the second box body 7 from the conveying pipe 10, the third motor 18 drives the square shaft 31 to rotate, and finally drives the rolling hollow hammer 24 to rotate. And the electric push rod 25 can also control its up-and-down reciprocating lifting. At this time, the telescopic rolling tube 28 installed on its circumferential side surface and the rolling head 29 installed on the bottom surface respectively crush and roll the lime, that is, realize the secondary crushing treatment of the lime, making the lime crushing more thorough and sufficient. After crushing, the lime can enter the inside of the thin elbow pipe 13 from the discharge hopper 71 and be discharged from the lime discharge port at the bottom. By adjusting the position of the thin elbow pipe 13 through the adjusting assembly 14, the line marking operation can be carried out.

[0052] The tapered rod 282 in the telescopic rolling tube 28 is responsible for crushing the lime. With the use of the spring 283, the crushing method of the tapered rod 282 can be more thorough and comprehensive.

[0053] Further, the adjusting assembly 14 includes a worm and gear speed reducer 141 installed on the top of the base 1. A driving gear 142 is installed on the reduction shaft of the worm and gear speed reducer 141. A limiting ring 131 is fixed at the upper end of the thin elbow pipe 13. The bottom of the second box body 7 is fixed with a discharge hopper 71. The bottom of the discharge hopper 71 and the upper end of the thin elbow pipe 13 are rotatably installed through the limiting ring 131. And a driven gear 143 is installed at the upper end of the thin elbow pipe 13. The driving gear 142 is in meshing transmission with the driven gear 143.

[0054] The worm and gear speed reducer 141 drives and controls the driving gear 142 to be in meshing transmission with the driven gear 143, so that the thin elbow pipe 13 can rotate to adjust the angle and the operation range, and it is convenient to store the thin elbow pipe 13.

[0055] Further, the lower end of the thin elbow pipe 13 is detachably installed with a rotary joint 15 by threads. The rotary joint 15 is in the shape of a long box, and a rectangular lime discharge groove is opened at the bottom. The rotary joint 15 can be installed, so that when the lime is discharged and line marking is carried out on the ground, the drawn line is more regular.

[0056] In the present invention, the structures of the first box body 6, the second box body 7, the arc-shaped elbow 9, the conveying pipe 10, and the rolling empty hammer 24 are all in a detachable form, so as to facilitate the internal maintenance.
