Description

Technical Field

[0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to an agricultural automated trenching machine. Background Art

[0002] With the continuous advancement of modern agricultural technology, the mechanization and automation of agricultural production are increasing day by day. As an important part of agricultural production, ditching is widely used in many fields such as farmland irrigation, drainage, fertilization and planting. Traditional ditching operations mainly rely on manual labor and simple mechanical tools, which are not only inefficient but also labor-intensive and cannot meet the needs of large-scale agricultural production.

[0003] Traditional trenching methods usually use simple tools such as hoes and shovels. Manual operation is not only time-consuming and laborious, but also the depth and width of the trenches are difficult to ensure consistency, affecting the irrigation and drainage effects of farmland. In large-scale agricultural production, traditional trenching methods are difficult to meet the requirements of efficient and precise operations. In order to solve the above problems, agricultural trenchers came into being. Agricultural trenchers are a type of mechanical equipment specially used for trenching operations. They use mechanical power to drive cutters or shovels to excavate soil and form trenches. Compared with traditional manual trenching, agricultural trenchers have the advantages of high work efficiency, high trenching accuracy, and easy operation, which greatly improves the mechanization level of agricultural production.

[0043] The power mechanism is installed on the frame 1, and is used to drive the frame 1 and the depth adjustment mechanism to move. The power mechanism includes a second motor 26 fixedly installed on the frame 1, a driving gear 25 is fixedly installed on the output shaft of the second motor 26, the driving gear 25 is rotatably installed on the frame 1, a second rotating disk 24 is fixedly installed on the driving gear 25, one end of a second rotating rod 23 is rotatably connected to the second rotating disk 24, the other end of the second rotating rod 23 is connected to the guide block 22, the second rotating rod 23 is slidably matched with a second horizontal rod 27, the second horizontal rod 27 is connected to a driving arm 28, and the second horizontal rod 27 is slidably matched with the frame 1.

[0044] The power mechanism also includes a rack 38 slidably mounted on the frame 1, a return spring 2 39 is arranged between the rack 38 and the frame 1, the rack 38 meshes with the driving gear 25, a lifting frame 37 is arranged on the rack 38, and a mounting shaft 36 is slidably mounted on the lifting frame 37, and both ends of the mounting shaft 36 are respectively slidably matched with two vertical frames 44 fixedly mounted on the frame 1, one end of the mounting shaft 36 is fixedly connected to the output shaft of the travel motor 47, the mounting shaft 36 forms a spline match with the adjusting gear 35, the adjusting gear 35 meshes with the shifting gear set 40, the shifting gear set 40 is composed of a plurality of shifting gears with different diameters, the shifting gear set 40 is fixedly connected to the transmission shaft 41, the transmission shaft 41 is rotatably mounted on the frame 1, one end of two belt assemblies 42 are connected to the transmission shaft 41, and the other end of the two belt assemblies 42 is connected to the driving wheel 43, and the driving wheel 43 is used to drive the frame 1 and other rollers on the frame 1 to move.

[0045] Specifically, the belt assembly 42 is composed of two pulleys and a belt, the two pulleys are connected by a belt, one pulley is installed on the transmission shaft 41, and the other pulley is connected to the driving wheel 43. For those skilled in the art, the belt assembly 42 can be replaced by a chain.

[0046] Working principle: Before trenching the land, the height of the trenching plate 2 and the bracket 3 are adjusted according to the required trenching depth. In addition, the deeper the trench, the greater the resistance the trenching plate 2 encounters. At this time, the entire trencher is regarded as a whole, that is, the greater the resistance the trencher encounters, then the forward speed of the driving wheel 43 needs to be reduced to ensure that the trenching plate 2 will not be damaged during the trenching process.

[0047] Specifically, the second motor 26 fixedly mounted on the frame 1 is started, and the driving gear 25 is driven to rotate by the output shaft of the second motor 26 so that the frame 1 rotates. Since the second rotating disk 24 is fixedly connected to the driving gear 25, the second rotating disk 24 will rotate.

[0048] First, when the second rotating disk 24 rotates, the second rotating rod 23 connected to the second rotating disk 24 will rotate. At this time, the second rotating rod 23 will push the guide block 22 to slide along the frame 1 close to the side of the ditching plate 2. The guide block 22 is connected to the second push rod 21, so the second push rod 21 will also be close to the ditching plate 2, so that the adjustment rod 19 rotates on the frame 1. During the rotation, the end of the adjustment rod 19 connected to the bracket 3 will be lowered, and the end of the adjustment rod 19 connected to the second push rod 21 will be raised. Since the U-shaped groove 20 on the adjustment rod 19 is slidably matched with the frame 1, and the second push rod 21 is rotatably matched with the second push rod 21, the rotation of the adjustment rod 19 will not be interfered. During the process of the end of the adjustment rod 19 connected to the bracket 3 descending, the bracket 3 will drive the ditching plate 2 to descend, so that the height adjustment of the ditching plate 2 is completed, that is, the adjustment of the ditching depth is completed. In addition, since the first rectangular groove 4 on the bracket 3 is rotatably connected to the pull rod 45, the bracket 3 will not be interfered when it rotates with the adjustment rod 19.

[0049] Secondly, when the driving gear 25 rotates, the rack 38 meshing with the driving gear 25 will slide along the frame 1. During this process, the reset spring 2 39 will deform and generate elastic force. The function of the reset spring 2 39 is to assist the reset of the rack 38. During the sliding process of the rack 38, the lifting frame 37 and the adjustment gear 35 on the rack 38 will move to the side close to the travel motor 47. Since the adjustment gear 35 and the mounting shaft 36 are splined, the movement will not be interfered. In addition, the diameters of the multiple adjustment gears on the transmission shaft 41 increase in sequence toward the direction close to the travel motor 47 (such as Fig.12), so the adjusting gear 35 will move to mesh with the shift gear with a larger diameter. The specific adjusting gear meshing is determined by the depth of the trenching. After the adjusting gear 35 meshes with a shift gear with a certain diameter in the shift gear set 40, the adjusting gear 35 will always remain meshed with this shift gear during the entire trenching process. And the number of teeth of any shift gear in the shift gear set 40 is greater than the number of teeth of the adjusting gear 35. The purpose of this is that when the second rotating disk 24 and the driving gear 25 rotate at a greater angle, the adjusting rod 19 and the bracket 3 descend to a greater height, and the trenching depth is greater at this time, the adjusting gear 35 moves a greater distance with the rack 38, and the adjusting gear 35 finally meshes with the shift gear with a larger number of teeth in the shift gear set 40. In this way, during the trenching process, the rotation speed of the driving wheel 43 will be lower, thereby ensuring that the trenching plate 2 can trench smoothly.

[0050] At the same time, in the process of the second turntable 24 driving the second turn rod 23 to rotate, the second turn rod 23 will drive the second horizontal rod 27 to slide on the frame 1, and the second horizontal rod 27 drives the driving arm 28 to move, so that the driving arm 28 drives the third turntable 29 to rotate. Since the third turntable 29 is fixedly connected to the control shaft 30, the control shaft 30 will rotate, and then the two discs 33 fixedly connected to the control shaft 30 will rotate inside the discharge pipe 34, so that the discs 33 and the inside of the discharge pipe 34 are no longer completely in contact, and a gap is generated. In this way, water and fertilizer in the storage barrel 31 can enter the lower end of the discharge pipe 34 through the discs 33, and then fall into the ground after ditching.

[0051] After completing the depth adjustment, the width of the trenching is adjusted according to the needs of trenching. Specifically, the electric cylinder 6 fixedly installed on the bracket 3 is started, so that the protruding end of the electric cylinder 6 pushes the two first push rods 5, so that the two first push rods 5 respectively push the two trenching plates 2 to rotate on the bracket 3, so that the angle between the two trenching plates 2 is increased, thereby increasing the width of the trenching; in addition, since the scraper 7 and the trenching plate 2 are slidably matched, the angle between the scrapers 7 is also increased during the increase of the angle between the two trenching plates 2, so that the connector 12 on the scraper 7 will drive the first connecting rod 13 to move, and the first connecting rod 13 and the second connecting rod 14 are slidably matched, so the first connecting rod 13 drives the second connecting rod 14 to move, so that the second connecting rod 14 drives the side plate 15 to slide on the frame 1, so as to ensure that the movement of the side plate 15 is consistent with that of the trenching plate 2. The purpose of this is that during the trenching process, the side plate 15 can gather the soil on both sides of the trench, making the land more tidy and the boundary between adjacent trenches more obvious.

[0052] After the width and depth of the trenching are adjusted, the travel motor 47 is started, so that the mounting shaft 36 fixedly connected to the output shaft of the travel motor 47 drives the adjusting gear 35 to rotate, and the adjusting gear 35 causes the shift gear meshing with the adjusting gear 35 in the shift gear set 40 to rotate, so that the transmission shaft 41 rotates on the frame 1, so that the belt assembly 42 connected to the transmission shaft 41 will drive the driving wheel 43 to rotate, so that the driving wheel 43 drives the frame 1 and other rollers on the frame 1 to move forward, so that the trenching plate 2 can be driven to trench, and in the trenching process, the water and fertilizer in the two storage barrels 31 pass through the disc 33 and enter the bottom of the discharge pipe 34, and fall into the trench opened by the trenching plate 2 through the bottom of the discharge pipe 34, and the deeper the trench is, the greater the rotation angle of the disc 33, and the more water and fertilizer enter the discharge pipe 34 per unit time.

[0053] In the process of trenching, soil will inevitably remain on the surface of the trenching plate 2, which will increase the difficulty of trenching. In this way, the resistance of the trenching plate 2 will increase, and the pressure transmitted from the trenching plate 2 to the pressure plate 46 through the bracket 3 will increase. At this time, the pressure plate 46 transmits the pressure information to the control center, and the control center controls the first motor 16 to start. At this time, the first rotating disk 17 fixedly connected to the output shaft of the first motor 16 will drive the first rotating rod 18 to rotate, so that the first rotating rod 18 drives the first horizontal rod 10 to move up and down reciprocatingly, and then the scraper 7 connected to the first horizontal rod 10 will move up and down reciprocatingly along the guide rod 8. The function of the first reset spring 9 is to assist the scraper 7 to reset. The scraper 7 moves up and down relative to the trenching plate 2, so as to scrape off the soil remaining on the surface of the trenching plate 2, thereby reducing the trenching resistance of the trenching plate 2 and ensuring that the trenching plate 2 can complete the trenching smoothly.
