[0034] like Figure 1 As shown, a tea garden trenching and fertilizing integrated machine includes a complete machine frame, a traveling mechanism 1, a control console 2, a fertilizing mechanism 3 and a trenching and soil covering mechanism 4, and the traveling mechanism 1, the control console 2, the fertilizing mechanism 3 and the trenching and soil covering mechanism 4 are connected into a whole through the complete machine frame.

[0035] The tea garden trenching and fertilizing all-in-one machine adopts a double-sided independently driven crawler-type walking chassis, the walking mechanism 1 is connected and fixed to the whole machine frame and arranged below the whole machine frame; the fertilization mechanism 3 is connected and fixed to the whole machine frame and arranged above the whole machine frame; the trenching and soil covering mechanism is connected and fixed to the whole machine frame and arranged behind the whole machine frame; the control console 2 is connected and fixed to the whole machine frame and arranged in front of the whole machine frame, which is used for the driver to control the movement of the whole vehicle and each mechanism when driving.

[0036] like Figure 2 As shown, the walking mechanism 1 includes: a track unit, a square tube 113 , a walking system motor 110 , and a walking system reducer 111 .

[0037] There are two track units and they are respectively arranged on both sides of the whole machine frame. The track unit includes a crawler 11, a supporting roller connecting plate 14, a fourth supporting roller 12, a third supporting roller 13, a second supporting roller 16, a first supporting roller 17, a travel drive wheel 19 and a tensioning wheel 116. The fourth supporting roller 12, the third supporting roller 13, the second supporting roller 16 and the first supporting roller 17 are all track wheels and mesh with the downward track. The travel drive wheel 19 and the tensioning wheel 116 are all track wheels and mesh with the upward track of the crawler 11. The crawler 11 is a circulating crawler, and the crawler 11 is supported by the fourth roller 12, the third roller 13, the second roller 16, the first roller 17, the travel drive wheel 19 and the tension wheel 116. The fourth roller 12 and the first roller 17 are respectively arranged at the two ends of the roller connecting plate 14, and the third roller 13 and the second roller 16 are respectively arranged at the two ends of the L-shaped middle roller connecting plate 15. The two arms of the middle roller connecting plate 15 are equal in length, and the turning part of the middle roller connecting plate 15 is hinged to the middle part of the roller connecting plate 14. The middle roller connecting plate 15 can rotate freely relative to the roller connecting plate 14, so as to realize the automatic change of the relative position of the third roller 13 and the second roller 16 when the terrain changes, and adapt to the influence of the deformation of the descending crawler of the crawler 11 caused by different terrains.

[0038] The tension wheel 116 is arranged at one end of the tension wheel connecting rod 115, and the other end of the tension wheel connecting rod 115 is inserted into one end of the opening of the tension wheel guide cylinder 117.

Figure 2 As shown, when the tensioning bolt 114 rotates in the tensioning threaded hole, the threaded end of the tensioning bolt 114 drives the tensioning wheel connecting rod 115 to move to the left, and the tensioning wheel 116 is tightly against and meshed with the track 11, and the tensioning force of the track 11 increases; when the tensioning bolt 114 rotates in the tensioning threaded hole, the threaded end of the tensioning bolt 114 drives the tensioning wheel connecting rod 115 to move to the right, the tensioning wheel 116 is tightly against and meshed with the track 11, and the tensioning force of the track 11 decreases. The position of the tensioning wheel connecting rod 115 can be adjusted by rotating the tensioning bolt 114, thereby adjusting the position of the tensioning wheel 116 to achieve a tensioning effect.

[0039] In some embodiments, the cross-sections of the tensioning wheel connecting rod 115 and the tensioning wheel guide tube 117 are square, circular, triangular, etc.

[0040] The travel driving wheel 19 is arranged on the driving wheel connecting plate 18 , and the driving wheel connecting plate 18 and the supporting wheel connecting main plate 14 are fixedly connected.

[0042] The walking mechanism 1 is attached to the working surface by a crawler 11. The forward and backward movement of the device can be controlled by controlling the forward and reverse rotation of the walking system motor 110, and left and right turns can be achieved by changing the rotation speed of the walking system motor 110.

[0043] like Figure 3 As shown, the trenching and covering mechanism 4 includes: a trenching cutter disc 21, a trenching blade 22, a trenching main shaft 23, a second trenching drive sprocket 24, a trenching drive chain 25, a hydraulic telescopic rod 26, a trenching first drive sprocket 27, a trenching pulley shaft 28, a trenching fixed box 29, a trenching belt 210, a first small pulley 211, a trenching pulley 212, a trenching cutter disc shell 213, a fertilizing plate 214, a covering plate 215 and a separable soil type fertilization straight pipe 216.

[0044] The diesel engine is arranged on the frame of the whole machine near the side of the trenching and covering mechanism 4, the center of the first small pulley 211 is sleeved and fixed on the output shaft of the diesel engine, the first small pulley 211 and the trenching pulley 212 are connected by the trenching belt 210, the center of the trenching pulley 212 and the center of the trenching first transmission sprocket 27 are sleeved and fixed on the trenching pulley shaft 28, the trenching pulley shaft 28 passes through the trenching fixed box 29 and is arranged on the trenching fixed box 29 by a bearing, the trenching pulley shaft 28 can rotate freely relative to the trenching fixed box 29, and the trenching fixed box 29 is fixed on the upper surface of the rear end of the whole machine frame. The trenching first transmission sprocket 27 and the second trenching transmission sprocket 24 are connected by the trenching transmission chain 25, the center of the second trenching transmission sprocket 24 and the center of the trenching cutter disc 21 are sleeved and fixed on the trenching main shaft 23, and the second trenching transmission sprocket 24 and the trenching cutter disc 21 are connected by the trenching main shaft 23.

[0045] When the diesel engine is started, the diesel engine output shaft drives the first small pulley 211 to rotate, and then drives the groove opening pulley 212 to rotate through the groove opening belt 210, and the groove opening pulley 212 drives the groove opening first transmission sprocket 27 to rotate synchronously, and the groove opening first transmission sprocket 27 drives the second groove opening transmission sprocket 24 to rotate through the groove opening transmission chain 25, and finally the second groove opening transmission sprocket 24 drives the groove opening main shaft 23 to rotate synchronously, thereby realizing the rotation operation of the groove opening cutter disc 21 mounted on the groove opening main shaft 23.

[0046] There are two trenching cutter discs 21. The center of the left trenching cutter disc 21 and the center of the right trenching cutter disc 21 are both mounted and fixed on the trenching main shaft 23 to realize the synchronous rotation of the two trenching cutter discs 21. Each trenching cutter disc 21 is provided with a plurality of threaded holes for installing trenching blades 22. One end of the trenching blade 22 is connected to the corresponding threaded hole on the trenching cutter disc 21 through a fixing bolt. The trenching blades 22 on each trenching cutter disc 21 are surrounded on the trenching cutter disc 21 and are evenly distributed to achieve the purpose of efficient trenching.

[0047] In this example, the number of grooving blades 22 provided on a single grooving cutter disc 21 is eight.

[0048] In some embodiments, both ends of the trenching main shaft 23 are respectively arranged on the trenching cutter disc housing 213 through bearings, and both ends of the trenching pulley shaft 28 are respectively arranged on the trenching cutter disc housing 213 through bearings. The middle part of the trenching cutter disc housing 213 is connected to the whole machine frame through a hydraulic telescopic rod 26. The hydraulic telescopic rod 26 plays a role in supporting the trenching and covering mechanism 4. The trenching depth can be adjusted by adjusting the length of the hydraulic telescopic rod 26. Preferably, the fixed seat of the hydraulic telescopic rod 26 is set on the whole machine frame, and the telescopic end of the hydraulic telescopic rod 26 is hinged to the middle part of the trenching cutter disc housing 213.

[0049] The front end of the fertilizing plate 214 is fixedly connected to the trenching cutter disc shell 213, and a fertilizer discharge hole is provided on the fertilizing plate 214. The top of the separable soil-type fertilizing straight pipe 216 is a fertilizer inlet end fixedly connected to the fertilizer discharge hole. The rear end of the fertilizing plate 214 is fixedly connected to the covering plate 215. The fertilizing plate 214 and the covering plate 215 cover the rear of the trenching cutter disc 21. The separable soil-type fertilizing straight pipe 216 is located between the trenching blade 22 and the covering plate 215. When the trenching cutter disc 21 is operating, the soil is thrown backwards, and the soil is divided by the separable soil-type fertilizing straight pipe 216 to protect the fertilization process. The soil is hit on the covering plate 215 to break the soil and backfill it on the trenching ground, achieving the effect of loosening the soil and covering the soil.

[0050] like Figure 4 As shown, the fertilization mechanism 3 includes: a second small pulley 31, a fertilization belt 32, a fertilization pulley 33, a bearing seat 34, an auger shaft 35, a fertilizer box 36, a fertilizer box baffle 37, and a fertilization pipe 38.

[0051] The fertilizer box 36 is arranged on the whole machine frame, and a mounting hole is arranged at the bottom of the fertilizer box 36. The screws are screwed into the threaded holes above the whole machine frame through the mounting holes at the bottom of the mounting side plate of the fertilizer box 36 so that the fertilizer box 36 is installed above the whole machine frame. A fertilizer channel 39 is arranged at the bottom of the fertilizer box 36, and the fertilizer channel 39 is connected to the fertilizer discharge hole on the fertilizer plate 214 through a fertilizer pipe 38.

[0052] Bearing seats 34 are provided on two pairs of side walls of the fertilizer box 36, and two ends of the auger shaft 35 are respectively arranged on the bearing seats 34 of the two pairs of side walls of the fertilizer box 36 through bearings, so that the auger shaft 35 can rotate freely relative to the bearing seats 34, and the fertilization channel 39 is located below the discharge end of the auger shaft 35. The other end of the auger shaft 35 is axially connected to the rotating shaft of the fertilization pulley 33. The fertilization pulley 33 is connected to the second small pulley 31 through the fertilization belt 32. The rotating shaft of the second small pulley 31 is axially connected to the output shaft of the diesel engine. When the diesel engine is running, the second small pulley 31 drives the fertilization pulley 33 to rotate, thereby driving the rotation of the auger shaft 35. The rotation of the auger shaft 35 can drive the fertilizer in the fertilizer box 36 to move to the fertilization channel 39 along the rotation direction of the auger shaft 35.

[0054] Since a fertilization channel 39 is provided at the lower part of the fertilizer box 36, the fertilization channel 39 is connected to the separable soil type fertilization straight pipe 216 on the fertilization plate 214 through the fertilization pipe 38, the fertilization pulley 33 and the auger shaft extending from the auger shaft 35 rotate synchronously, driving the auger shaft 35 to rotate, and the auger shaft 35 transports the fertilizer horizontally to the fertilization hole under the fertilizer box baffle 37 by rotation, and enters the fertilization pipe 38 through the fertilization hole. The fertilizer enters the separable soil type fertilization straight pipe 216 from the fertilization pipe 38, and the fertilizer smoothly enters the soil in which the ditching is completed while the ditching and covering mechanism 4 is ditching. The fertilizer box baffle 37 in the fertilizing mechanism 3 is installed on the side of the fertilizer box 36 close to the fertilizing channel 39. When the auger shaft 35 is not running, the fertilizer cannot be brought into the fertilizing hole under the fertilizer box baffle 37 through the auger shaft 35. When the tea garden trenching and fertilizing integrated machine is not performing trenching operations, the fertilizer box baffle 37 can prevent fertilizer from entering the fertilizing channel 39.

[0055] In some embodiments, a valve for controlling the conduction area of ​​the fertilization channel 39 is also provided on the fertilization channel 39. The valve can be adjusted according to the actual use of the tea garden to adjust the channel size of the fertilization channel 39 so as to achieve the effect of regulating the amount of fertilizer.

The controller 47 is connected to the wireless receiver 44, the PWM speed regulator 45, the electromagnetic starter and stopper 46, and the hydraulic telescopic rod 26 respectively. The controller is connected to the travel system motor 110 through the PWM speed regulator 45 and the corresponding electromagnetic starter and stopper 46 in turn, and the controller is connected to the diesel engine through the corresponding electromagnetic starter and stopper 46.

[0058] The control system can realize wireless control of the furrowing and fertilizing operation. During operation, the operation instructions are sent to the controller 47 through the wireless receiver 44 via the wireless transmitter 43.

[0059] The controller 47 analyzes the working state of the electromagnetic starter and stopper 46 and the speed and direction of the travel system motor 110 according to the operation instruction.

[0060] The controller 47 controls the on and off of the electromagnetic starter and stopper 46 corresponding to the PWM speed regulator according to the operation instruction, and further controls the on and off of the control path of the PWM speed regulator 45 to the walking system motor 110.

[0061] The controller 47 controls the speed and direction of the travel system motor 110 through the PWM speed regulator 45 according to the operation instruction.

[0062] The controller 47 dynamically adjusts the length of the hydraulic telescopic rod 26 according to the operation instruction.

[0063] The controller 47 controls the on and off of the electromagnetic starter and stop device 46 corresponding to the diesel engine according to the operation instruction, thereby controlling the start and stop of the diesel engine.

[0064] Diesel engines can be replaced by gasoline engines, electric motors and other power sources.
