[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] refer to Figures 1 to 9 : An automatic retractable grape planting fertilizing and watering device comprises a carrier vehicle 1 and a tractor for towing the carrier vehicle 1. A front support shaft 4 and a rear support shaft 8 are rotatably arranged below the front and rear ends of the carrier vehicle 1, respectively. The two ends of the front support shaft 4 are coaxially fixedly connected to the front load-bearing wheel 7, and the two ends of the rear support shaft 8 are fixedly connected to the rear load-bearing wheel 11. The device also comprises a variable pitch mechanism, a lifting mechanism, a pumping mechanism, a vibration mechanism, a fertilizer box 2 fixedly arranged on the carrier vehicle 1, and a water storage tank 3. The variable pitch mechanism is arranged below the carrier vehicle 1. The variable pitch mechanism comprises two telescopic output ends that can move synchronously toward each other. The lifting mechanism is arranged on the telescopic output end. The lifting mechanism comprises a lifting output end that can move up and down. The soil-breaking plow 59 is provided with a discharge port 60, and a pumping mechanism is provided below the carrier vehicle 1. The pumping mechanism has a spraying output end, which is connected to the soil-breaking plow 59. The spraying output end is used to spray the water in the water storage tank 3 onto the soil surface. The vibration mechanism includes a material transfer three-way pipe 22 elastically arranged below the carrier vehicle 1 and connected to the inside of the fertilizer box 2, a discharge bellows 24 arranged at both ends of the material transfer three-way pipe 22, and a vibration output end. The vibration output end is used to drive the material transfer three-way pipe 22 to vibrate, one end of the discharge bellows 24 is connected to the inside of the soil-breaking plow 59, and the other end is connected to the material transfer three-way pipe 22.

[0021] When the device is in operation, the carrier vehicle 1 is towed by the tractor. When fertilizing, the variable pitch mechanism operates first, and the telescopic output end drives the soil-breaking plow 59 to move to the appropriate distance of the grape row. Then the lifting output end of the lifting mechanism drives the soil-breaking plow 59 to be inserted into the soil. Then the tractor pulls the carrier vehicle 1 to start moving. During the moving process, the fertilizer in the fertilizer box 2 first enters the material transfer three-way pipe 22, and then enters the soil-breaking plow 59 through the discharge bellows 24, and finally is discharged from the discharge port 60. During the fertilization process, the vibration output end of the vibration mechanism drives the material transfer three-way pipe 22 to vibrate, so as to ensure that the fertilizer can flow smoothly and prevent the fertilizer from being blocked in the material transfer three-way pipe 22 and the discharge bellows 24. In addition, during the fertilization process, the pump liquid mechanism also sprays the water in the water storage tank 3 to the soil surface through the spraying output end, so as to facilitate the dissolution of the fertilizer and accelerate the absorption of the grapes.

[0022] In order to show the detailed structure of the pitch-changing mechanism, the following features are also set: The pitch-changing mechanism also includes a driving motor 12 fixedly arranged at the bottom of the carrying vehicle 1, a reversing gear box 13 fixedly arranged beside the driving motor 12, a carrying tube 14 symmetrically arranged on both sides of the reversing gear box 13 and fixedly connected to the carrying vehicle 1, a supporting screw 15 coaxially arranged in each carrying tube 14, a supporting screw 16 coaxially arranged in each supporting screw 15, a limiting tube 17 symmetrically arranged on both sides of each carrying tube 14 and fixedly connected to the carrying vehicle 1, a limiting rod 18 coaxially slidably arranged in each limiting tube 17, a supporting plate 19 fixedly arranged at the ends of the two limiting rods 18, and a supporting bracket 20 fixedly arranged on the supporting plate 19, the supporting screw 16 is threadedly connected to the supporting screw 15, one end of the supporting screw 16 close to the supporting plate 19 is fixedly connected to the supporting plate 19, and one end of the supporting screw 15 away from the supporting plate 19 is connected to the reversing gear box 13, and the reversing gear box 13 is connected to the output shaft of the driving motor 12.

[0023] The supporting bracket 20 is the telescopic output end of the pitch-changing mechanism.

[0024] When the device is running, the driving motor 12 drives the two supporting screws 15 to rotate through the reversing gear box 13 (it should be noted that the reversing gear box 13 is a bevel gear set, which is a mature existing technology and will not be repeated here). The rotation of the supporting screw 15 causes the supporting screw 16 to move along the axis of the supporting screw 15, and then cooperates with the two limit rods 18 and the supporting plate 19 to drive the supporting bracket 20 to move, thereby realizing flexible adjustment of the distance between the two soil-breaking plows 59, which is convenient for adapting to the working environment of different varieties of grape plantations.

[0025] In order to show the detailed structure of the lifting mechanism, the following features are also set: The lifting mechanism includes a push rod 35 fixedly arranged on each supporting bracket 20, a transfer box 36 arranged below the supporting bracket 20, and a limit slide bar 37 symmetrically fixedly arranged on both sides of the transfer box 36. The transfer box 36 is fixedly connected to the output shaft of the push rod 35, the limit slide bar 37 passes through the supporting bracket 20, the soil-breaking plow 59 is arranged at the bottom of the transfer box 36, and the end of the discharge bellows 24 away from the transfer tee pipe 22 is connected to the inside of the transfer box 36.

[0026] The transfer box 36 is the lifting output end of the lifting mechanism.

[0027] During fertilization, the output shaft of the push rod 35 drives the transfer box 36 to move downward. The two limit slide bars 37 can ensure that the transfer box 36 is more stable during movement. The downward movement of the transfer box 36 drives the soil-breaking plow 59 to be inserted into the soil. When the appropriate depth is reached, the output shaft of the push rod 35 stops extending, and then the tractor pulls the carrier vehicle 1 forward to complete the subsequent fertilization work.

[0028] In order to show the detailed structure of the soil-breaking plow 59, the following features are also specifically provided: The soil-breaking plow 59 includes two limiting triangles 38 symmetrically fixed at the bottom of the transfer box 36, a soil-breaking bottom block 39 fixed at the bottom of the two limiting triangles 38, a guide side plate 40 arranged on one side of the soil-breaking bottom block 39 and fixedly connected to the two limiting triangles 38, a limiting side plate 41 arranged on one side of the guide side plate 40 and fixedly connected to the two limiting triangles 38, a sealing plate 46 slidably arranged on the limiting side plate 41 and a soil dividing block 51 fixedly arranged on a limiting triangle plate 38, and a discharge port 60 is formed between the bottom of the limiting side plate 41 and the soil-breaking bottom block 39.

[0029] In order to show the specific installation details of the blocking plate 46, the following features are also specifically provided: A sliding waist groove 45 is provided on each limiting triangle plate 38, and sliding bosses 47 are formed on both sides of the blocking plate 46. The sliding bosses 47 correspond to the sliding waist groove 45 one by one and slide in cooperation. A limiting buckle plate 43 is fixedly arranged on the side of the limiting side plate 41. One side of the blocking plate 46 slides in cooperation with the limiting side plate 41, and the other side slides in cooperation with the limiting buckle plate 43. A limiting waist groove 42 is provided on the limiting side plate 41, and a limiting column 48 is fixedly arranged on the blocking plate 46. The limiting column 48 penetrates the limiting waist groove 42 and slides in cooperation with the limiting waist groove 42. A spring piece 44 is provided on the limiting buckle plate 43, and one end of the spring piece 44 is fixedly connected to the limiting buckle plate 43, and the other end is fixedly connected to the blocking plate 46.

[0030] In order to ensure that after the soil-breaking plow 59 is inserted into the soil, the blocking plate 46 can overcome the elastic force of the spring sheet 44 to open the discharge port 60, the following features are also specifically provided: A lifting rod 52 is slidably provided on the supporting bracket 20, and a pressure spring 55 is coaxially sleeved on the lifting rod 52. A wheel frame 53 is provided at the bottom end of the lifting rod 52, and a resistance wheel 54 is rotatably provided on the wheel frame 53. A limiting ring is provided at the top of the lifting rod 52, and the bottom of the limiting ring is abutted against the top of the supporting bracket 20. One end of the pressure spring 55 is connected to the bottom of the supporting bracket 20, and the other end is connected to the wheel frame 53. A pull rope 50 is provided on the wheel frame 53, and one end of the pull rope 50 is fixedly connected to the wheel frame 53, and the other end is fixedly connected to the limiting column 48. A baffle 49 is fixedly provided on the limiting column 48, and the baffle 49 is used to block the limiting waist groove 42.

[0031] When the device is running, the material transfer box 36 drives the soil-breaking plow 59 to move downward. During this process, the soil-breaking bottom block 39 first contacts the soil, and then under the pressure of the push rod 35, the soil-breaking bottom block 39 is inserted into the soil and separates the soil to both sides. As the insertion continues, the resistance wheel 54 contacts the soil and compresses the pressure spring 55 (it should be noted that the soil surface is used as a reference here, the wheel frame 53 is stationary, and the blocking plate 46 moves downward). At this time, the blocking plate 46 is inserted into the soil as the soil-breaking bottom block 39 is inserted into the soil, and the pull rope 50 on the wheel frame 53 will pull the limiting column 48 to slide in the limiting waist groove 42. The sliding of the column 48 drives the blocking plate 46 to move, and the movement of the blocking plate 46 squeezes the spring piece 44, thereby opening the discharge port 60 (in this process, the two sliding protrusions 47 slide in the sliding waist groove 45), and then the fertilizer enters the transfer box 36 from the discharge bellows 24, and finally falls into the broken soil from the discharge port 60; after waiting for the fertilization to be completed, the output shaft of the push rod 35 drives the soil-breaking plow 59 to reset, and at this time the conflict wheel 54 no longer conflicts with the soil surface, the pressure spring 55 drives the wheel frame 53 to reset, and the spring piece 44 drives the blocking plate 46 to reset, so that the discharge port 60 is blocked to prevent the fertilizer from spilling.

[0032] In order to show the detailed structure of the vibration mechanism, the following features are also set: The vibration mechanism also includes two first limit brackets 25 symmetrically arranged at the bottom of the carrier 1, a first cam 26 rotatably arranged on the two first limit brackets 25, a rotating wheel 27 coaxially fixedly connected to the rotating axis of the first cam 26, a transfer wheel 28 rotatably arranged on the first limit bracket 25 close to the rotating wheel 27, a first transmission wheel 5 coaxially fixedly arranged on the front support shaft 4, a first connecting belt 6 arranged between the first transmission wheel 5 and the transfer wheel 28, and a transfer belt 29 arranged between the transfer wheel 28 and the rotating wheel 27. A feed pipe 21 is fixedly arranged at the bottom of the fertilizer box 2. The feed pipe 21 passes through the carrier 1 and is key-connected with the material transfer three-way pipe 22. Two return springs 23 are symmetrically arranged on the material transfer three-way pipe 22. One end of the return spring 23 is fixedly connected to the carrier 1, and the other end is fixedly connected to the material transfer three-way pipe 22. The first cam 26 is against the bottom of the material transfer three-way pipe 22, and the first cam 26 is the vibration output end of the vibration mechanism.

[0033] When the device is running, as the carrier vehicle 1 moves forward, the rotation of the front support shaft 4 is transmitted through the first transmission wheel 5, the first connecting belt 6, the transfer wheel 28, the transfer belt 29 and the rotating wheel 27, thereby driving the first cam 26 to rotate. The first cam 26 rotates and repeatedly contacts the material transfer tee 22, so that the return spring 23 is repeatedly compressed, thereby realizing the shaking of the material transfer tee 22 in the discharge pipe 21, thereby preventing fertilizer from being blocked in the tee and the discharge bellows 24. It should also be noted that a valve for quantitatively releasing fertilizer is provided in the discharge pipe 21. This is a mature existing technology and will not be elaborated here.

[0034] In order to show the detailed structure of the pump mechanism, the following features are also set: The pumping mechanism also includes a pumping pipe 33 fixedly arranged at the bottom of the carrier vehicle 1 and connected to the inside of the water tank 3, a pumping piston rod 34 coaxially and elastically arranged in the pumping pipe 33, two second limiting brackets 30 symmetrically arranged at the bottom of the carrier vehicle 1, a second cam 31 rotatably arranged between the two second limiting brackets 30, a driven runner 32 coaxially fixedly arranged on the rotating shaft of the second cam 31, a second transmission wheel 9 coaxially fixedly arranged on the rear support shaft 8, a second connecting belt 10 arranged between the second transmission wheel 9 and the driven runner 32, a transfer pipe 56 fixedly arranged on the side wall of the transfer box 36, a plurality of nozzles 57 equally spaced on the transfer pipe 56 and a liquid outlet hose 58 arranged between the transfer pipe 56 and the pumping pipe 33, the nozzle 57 is the spraying output end of the pumping mechanism, and the second cam 31 is against the pumping piston rod 34.

[0035] During the forward movement of the carrier vehicle 1, the rotation of the rear support shaft 8 is transmitted through the second transmission wheel 9, the second connecting belt 10 and the driven rotating wheel 32, thereby driving the second cam 31 to rotate. The rotation of the second cam 31 repeatedly squeezes the pump piston rod 34. The pump piston rod 34 reciprocates in the pump pipe 33, thereby allowing the water in the water storage tank 3 to enter the liquid transfer pipe 56 through the liquid outlet hose 58, and finally sprayed from the nozzle 57 to the fertilized soil surface, thereby accelerating the dissolution of the fertilizer and facilitating the absorption of the grapes.

[0036] The working principle of the device is as follows: when using this device, the tractor pulls the carrier 1 to move to the middle position of two grape rows, and then the driving motor 12 drives the two supporting screws 15 to rotate through the reversing gear box 13. The rotation of the supporting screw 15 makes the supporting screw 16 move along the axis of the supporting screw 15, and then cooperates with the two limit rods 18 and the supporting plate 19 to drive the supporting bracket 20 to move, ensuring that the distance between the two soil-breaking plows 59 reaches a suitable position, and then the output shaft of the push rod 35 drives the material transfer box 36 to move downward. The two limit slide bars 37 can ensure that the material transfer box 36 is more stable during the movement. The downward movement of the material transfer box 36 drives the soil-breaking plow 59 to be inserted into the soil. During the process, the soil-breaking bottom block 39 first contacts the soil, and then under the pressure of the push rod 35, the soil-breaking bottom block 39 is inserted into the soil and separates the soil to both sides. As the insertion continues, the resistance wheel 54 contacts the soil and compresses the pressure spring 55. At this time, the sealing plate 46 is inserted into the soil along with the soil-breaking bottom block 39, and the pull rope 50 on the wheel frame 53 will pull the limiting column 48 to slide in the limiting waist groove 42, and the sliding of the limiting column 48 will drive the sealing plate 46 to move. The movement of the sealing plate 46 squeezes the spring piece 44, thereby opening the discharge port 60 (at this time, the appropriate depth has been reached. When the depth of fertilization required is different, it can be obtained by replacing the lifting rod 52 of different lengths), and then the push rod 35 stops moving. Then the tractor pulls the carrier 1 to start moving. During the movement, the soil blocks 51 separate the soil to facilitate the fertilizer to enter the soil. As the carrier 1 moves forward, the rotation of the front support shaft 4 is transmitted through the first transmission wheel 5, the first connecting belt 6, the transfer wheel 28, the transfer belt 29 and the rotating wheel 27, thereby driving the first cam 26 to rotate. The first cam 26 rotates and repeatedly contacts the material transfer tee 22, so that the return spring 23 is repeatedly compressed, thereby realizing the shaking of the material transfer tee 22 in the discharge pipe 21, thereby preventing fertilizer from being in the tee and The discharge bellows 24 is blocked, and then the fertilizer is discharged into the soil through the discharge port 60. At the same time, the rotation of the rear support shaft 8 is transmitted through the second transmission wheel 9, the second connecting belt 10 and the driven wheel 32, thereby driving the second cam 31 to rotate. The second cam 31 rotates and repeatedly squeezes the pump piston rod 34. The pump piston rod 34 reciprocates in the pump pipe 33, so that the water in the water storage tank 3 enters the transfer pipe 56 through the liquid outlet hose 58, and is finally sprayed from the nozzle 57 to the fertilized soil surface, which accelerates the dissolution of the fertilizer and facilitates the absorption of the grapes.

[0037] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
