[0002] In the field of tea plantation in my country, digging ditches is an important measure to ensure the irrigation and drainage of tea gardens. However, there are many problems with traditional ditch digging technology. On the one hand, the depth and width of the excavated ditch are difficult to accurately control, resulting in poor ditch digging effect, affecting the irrigation and drainage effect of the tea garden. On the other hand, improper treatment of the soil generated during the excavation process can easily cause backfilling of soil inside the ditch, resulting in ditch blockage and increasing the cost of later cleaning and maintenance. In addition, the traditional excavation method is inefficient, time-consuming and labor-intensive, and is not conducive to large-scale planting of tea gardens.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 10 A ditch excavation robot for tea mountain planting includes a driving seat 1, a mounting hole 2 is opened on the top of the driving seat 1, a storage barrel 3 is installed on the inner wall of the mounting hole 2, a crushing and cutting mechanism 4 is arranged inside the storage barrel 3, a discharging mechanism 5 is arranged at the bottom of the storage barrel 3, a lifting mechanism 6 is arranged on one side of the storage barrel 3, and a soil drilling mechanism 7, an excavation depth adjustment mechanism 8, a limit clamping mechanism 9 and a power driving mechanism 10 are respectively arranged on one side of the driving seat 1.

[0036] In order to realize the action of adjusting the drilling into the soil during ditch excavation; the drilling mechanism 7 includes an excavation plowshare 71, and retaining plates 72 are fixedly installed on both sides of the excavation surface of the excavation plowshare 71, and hinge shafts 73 are fixedly installed on both ends of the top of the excavation plowshare 71. A guide rail 74 is fixedly installed on the surface of one side of the driving seat 1, and a slider 75 is slidably inserted on the surface of the guide rail 74. A U-shaped seat 76 is fixedly installed on the surface of the slider 75, and the opposite surfaces on both sides of the U-shaped seat 76 are rotatably connected to the two ends of the hinge shaft 73 through bearings. An electric telescopic rod 77 is also fixedly installed on the surface of one side of the guide rail 74, and the telescopic end of the electric telescopic rod 77 is fixedly installed on the opposite surface of the U-shaped seat 76.

[0037] Specifically, the drilling mechanism 7 is set up to drive the excavation plowshare 71 to swing downward with the axis of the hinge shaft 73 as the center during channel excavation, so that it drills into the soil of the channel. The electric telescopic rod 77 performs a short-distance telescopic movement, driving the excavation plowshare 71 to swing left and right, and assisting the excavation depth adjustment mechanism 8 to adjust the operation.

[0038] In order to realize the action of adjusting the excavation depth during excavation by the drilling mechanism 7; the excavation depth adjustment mechanism 8 includes a bearing seat 81, and four bearing seats 81 are installed around the bottom of the excavation plowshare 71. The relative surfaces of every two bearing seats 81 are rotatably connected with a rotating shaft 82 through a bearing, and the surfaces of the two rotating shafts 82 are fixedly installed with conveying rollers 83, and the surfaces of the two conveying rollers 83 are connected with conveying belts 84, and the surface of the conveying belt 84 has a curved array of digging shovels 85, and a small sprocket 86 is fixedly installed at one end of one of the rotating shafts 82.

[0039] Specifically, before channel excavation, the excavation depth is adjusted by the excavation depth adjustment mechanism 8, and the rotation of the rotating shaft 82 is controlled to drive the conveyor roller 83 to rotate rapidly, thereby driving multiple shovels 85 on the surface of the conveyor belt 84 to rotate along with the conveyor belt 84, and then when the excavation plowshare 71 swings around the axis of the hinge shaft 73, the shovel 85 is driven to rotate rapidly downward to contact the soil for excavation operations, so as to facilitate the control of the excavation plowshare 71 to quickly enter the soil, and the drilling depth is adjusted by the swinging angle of the excavation plowshare 71, so as to avoid the bearing seat 81 causing the two sides of the excavation to be limited during excavation, and the electric telescopic rod 77 is used to perform a short-distance telescopic movement to offset the effect of the two sides being limited and unable to drill due to the bearing seat 81.

[0040] In order to realize the simultaneous driving action of the drilling mechanism 7 and the excavation depth adjustment mechanism 8; the power drive mechanism 10 includes a driving motor 101, which is installed on the other end surface of the slider 75, and the output shaft of the driving motor 101 is fixedly installed with a motor shaft 102 through a coupling, and one end of the motor shaft 102 is fixedly installed with a driving gear 103, and one end of the articulated shaft 73 is respectively fixedly installed with a driven gear 104 and a large sprocket 105, and the teeth of the driven gear 104 are meshed with the teeth of the driving gear 103, and the teeth of the large sprocket 105 and the teeth of the small sprocket 86 are both transmission-connected with a chain 106, and the tooth number ratio of the small sprocket 86 and the large sprocket 105 is 50:1.

[0041] Specifically, the power drive mechanism 10 is used to drive the drill bit mechanism and the excavation depth adjustment mechanism 8 at the same time. When the drive motor 101 is working, it drives the motor shaft 102 to rotate. The rotation of the motor shaft 102 drives the drive gear 103 to rotate, so that the drive gear 103 drives the driven gear 104 to rotate, and drives the large sprocket 105 to rotate together. The large sprocket 105 rotates 1 circle and drives the small sprocket 86 to rotate 50 circles, so that its rotating shaft 82 rotates rapidly. When the driven gear 104 rotates, it drives the articulated shaft 73 to rotate, so that the excavation plowshare 71 is driven to swing synchronously during the rotation of the large sprocket 105.

[0042] In order to realize the limiting clamping action of the limiting clamping mechanism 9 during the excavation of the drilling mechanism 7; the limiting clamping mechanism 9 includes an L connecting seat 91, one side of the bottom of the L connecting seat 91 is fixedly installed on the surface of the slider 75, and the other end surface of the L connecting seat 91 is provided with a transfer groove 92, and the inner walls on both sides of the transfer groove 92 are rotatably connected with a pin shaft 93 through bearings, and a ratchet pawl 94 is fixedly installed on the arc surface of the pin shaft 93, and one end of the ratchet pawl 94 is meshed with the tooth groove of the driven gear 104.

[0043] Specifically, after the excavation plowshare 71 has finished adjusting the excavation depth, the limit clamping mechanism 9 is used to control the articulated shaft 73 to limit the depth, so as to avoid the excavation depth changing during excavation, resulting in inconsistent and low precision of the excavation depth. In the limit clamping, one end of the ratchet 94 is clamped inside the driven gear 104 to fix the limit.

[0044] A limiting sleeve 95 is fixedly installed on one side surface of the L connecting seat 91, one end of the pin shaft 93 passes through and extends to the inside of the limiting sleeve 95, and a torsion rod 96 is fixedly installed on one end of the pin shaft 93. A torsion spring 97 is arranged inside the limiting sleeve 95, one end of the torsion spring 97 is fixedly installed on the surface of the L connecting seat 91, and the other end of the torsion spring 97 is fixedly installed on the surface of the torsion rod 96.

[0045] Specifically, when adjusting the excavation depth, the ratchet 94 swings to control the torsion rod 96 to squeeze the torsion spring 97, so that the ratchet 94 leaves the driven gear 104. After the depth adjustment is completed, the ratchet 94 is controlled to be engaged with the tooth groove of the driven gear 104 under the torsion force of the torsion spring 97 for engagement and limiting.

[0046] In order to realize the action of lifting and transporting soil during ditch excavation; the lifting mechanism 6 includes a protective cover 61, the bottom feeding end of the protective cover 61 is fixedly installed on the top of the U-shaped seat 76, and a discharge trough 62 is opened on one side of the top of the protective cover 61. The relative inner walls on both sides of the protective cover 61 are rotatably connected with conveying rollers 63 through bearings, and the surfaces of the two conveying rollers 63 are both transmission-connected with conveyor belts 64. The surface curve array of the conveyor belt 64 has an arc-shaped support plate 65, and a conveying motor 66 is fixedly installed on one side of the top of the protective cover 61. The output shaft of the conveying motor 66 is fixedly installed on the relative surface of the conveying roller 63 through a coupling.

[0047] Specifically, the driving seat 1 drives the excavation plowshare 71 to groove the soil while it is moving. When grooving, the soil in the groove will be shielded and protected by the retaining plates 72 on both sides of the excavation plowshare 71, so that the soil enters the interior of the protective cover 61, and the conveying motor 66 drives the conveying roller 63 to rotate, thereby driving the conveyor belt 64 to transmit, driving the arc-shaped support plate 65 on the surface to support the excavated soil and lift it to the top of the protective cover 61 to flow out from the discharge chute 62.

[0048] In order to realize the action of crushing and cutting the large pieces of soil lifted by the lifting mechanism 6; the crushing and cutting mechanism 4 includes a crushing and cutting blade 41, and a feed port 42 is opened on one side of the top of the storage barrel 3, and the feed port 42 corresponds to the discharge trough 62. A cutting motor 43 is fixedly installed on the top of the storage barrel 3, and a cutting shaft 44 is fixedly installed on the output shaft of the cutting motor 43 through a coupling. The arc surface of the cutting shaft 44 is fixedly installed on the surface of the crushing and cutting blade 41, and multiple crushing and cutting blades 41 are arranged in a circular array in the vertical direction of the cutting shaft 44, and a scraper 45 is fixedly installed on the bottom of the cutting shaft 44.

[0049] Specifically, after the excavated soil is lifted into the storage barrel 3, the cutting motor 43 is started to drive the cutting shaft 44 to rotate, thereby driving the multiple cutting blades in the circular array in the vertical direction of the surface to rotate and cut the incoming large pieces of soil to crush them into small pieces, thereby preventing the large pieces of soil in the excavation from falling into the excavated channel and causing the cost of subsequent cleaning. When it is necessary to control the arrangement of the cut soil pieces, the scraper 45 at the bottom is driven by the rotation of the cutting shaft 44 to move to arrange them.

[0050] In order to realize the discharge of fine soil crushed by the crushing and cutting mechanism 4; the discharge mechanism 5 includes a sealing plate 51, a discharge hole 52 is opened at the bottom of the storage barrel 3, and an arc cylinder 53 and a limit plate 54 are fixedly installed at the bottom of the storage barrel 3, and the telescopic end of the arc cylinder 53 is fixedly installed on the opposite surface of the sealing plate 51, and the other side of the sealing plate 51 is in contact with the surface of the limit plate 54, and the top of the sealing plate 51 corresponds to the surface of the discharge hole 52.

[0051] Specifically, when discharging is required, the arc cylinder 53 is contracted to drive the sealing plate 51 to move so that its arrangement holes are opened for discharging. When discharging is not required, the arc cylinder 53 is driven to extend to drive the sealing plate 51 to close the arrangement holes, and the limiting plate 54 is used to limit and block them.

[0052] The bottom of the driving seat 1 is provided with running wheels 11 all around, and the running wheels 11 are driven by a driving source installed inside the driving seat 1 . Counterweight blocks 12 are also provided on the top and surrounding surfaces of the driving seat 1 .

[0053] Specifically, during operation, the driving source inside the driving seat 1 is used to control the four walking wheels 11 for walking drive, driving the excavation plowshare 71 to excavate the channel, and the counterweight block 12 is used to enhance the equipment's own weight, so as to facilitate the excavation plowshare 71 to move forward for excavation.

[0054] In the channel excavation, the present invention controls the excavation plowshare 71 to drill into the soil through the provided soil drilling mechanism 7, and adjusts the excavation depth through the excavation depth adjustment mechanism 8. After the adjustment, the driving seat 1 is controlled to move and drive the excavation plowshare 71 to perform the excavation operation, so that the excavation depth can be automatically adjusted according to the demand, thereby enhancing the excavation efficiency. The excavated soil during the excavation is lifted by the lifting mechanism 6 to the inside of the crushing and cutting mechanism 4 to break the soil and crush it into small pieces, which is convenient for discharge later, and the soil during the excavation is prevented from entering the excavated channel again, thereby improving the efficiency of ditch excavation and ensuring the effect of ditch excavation, avoiding the cost of cleaning up the soil that has fallen into the channel again in the later stage, and preventing the excavated channel from being blocked by the soil that has fallen in again.

[0055] Working principle: Before excavation, first move to the channel excavation position through the driving seat 1, and then work simultaneously through the drilling mechanism 7 and the excavation depth adjustment mechanism 8, so that the excavation plowshare 71 is drilled into the soil while adjusting the excavation depth. During operation, the motor shaft 102 is driven to rotate by the driving motor 101, thereby driving the driving gear 103 at one end to rotate, and the driving gear 103 rotates to drive the driven gear 104 to rotate, thereby controlling the articulated shaft 73 to swing, and driving the excavation plowshare 71 to drill into the soil.

[0056] While the driven gear 104 is rotating, it also drives the large sprocket 105 to rotate, and through the gear ratio, it quickly drives the small sprocket 86 to rotate quickly, controls the rotating shaft 82 to quickly rotate and drive the transmission belt 84 to quickly transmit, drives the shovel 85 to perform digging operations, and then assists the excavation plowshare 71 to drill into the soil to adjust the excavation depth.

[0057] After the adjustment is completed, the pawl 94 is clamped inside the driven gear 104 for limited rotation, and the driving seat 1 is driven to drive the excavation plowshare 71 to perform excavation operations. While excavating, the retaining plates 72 on both sides are used to block the excavated soil, so that the conveying motor 66 can work to drive the conveying roller 63 to rotate, drive the conveyor belt 64 to transmit and then control the arc-shaped support plate 65 to drive the excavated soil to be lifted into the storage barrel 3, and the cutting motor 43 is used to work to drive the cutting shaft 44 to rotate, thereby driving the cutting blade to rotate and cut the excavated soil inside to crush it into small pieces.

[0058] After excavation is completed, the storage barrel 3 is controlled to move to other positions for discharging operations, and the sealing plate 51 is driven to leave the discharging hole 52 by the contraction of the arc cylinder 53, so that the soil cut by the scraper 45 is discharged during its rotation.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
