Description

Technical Field

[0002] Smart agriculture is a new direction for agricultural development. It has changed the traditional agricultural model of relying on the environment for planting and extensive production management, adjusted the agricultural industrial structure, ensured the total output of agricultural products, efficiently utilized various agricultural resources, and improved the quality of agricultural products to a great extent.

[0003] In the planting management of grape fields, if the fertilization of the whole garden is completed manually, there are problems of low efficiency and high work intensity. The existing patent CN202121976101.4 discloses a multifunctional grape planting fertilization equipment with adjustable fertilization spacing. While the fertilizer applicator is moving, the transmission rod and the fixed circular plate are driven to rotate by a stepper motor, and the connecting rod outside the fixed circular block is driven to rotate, thereby driving the fixed plate and the block to move up and down, so that the fertilizer falls out through the fertilization port, and when the spacing needs to be adjusted, it is only necessary to adjust the rotation speed of the stepper motor or the size of the fixed circular plate to make the baffle move up and down at different rates, thereby controlling the fertilization between the spacing of the fertilizer applicator. In order to avoid the fertilizer remaining in the guide rail from getting stuck in the roller during the movement of the fertilizer applicator, a fixed block is provided at the front end of the connecting seat, and the conical block at the front end of the fixed block can discharge the fertilizer and sediment in the guide rail through the through hole. While the fertilizer applicator is moving, the lifting rod at the upper end of the water storage tank is started to drive the sprinkler to rise, spray the orchard passed by, and speed up the efficiency of the orchard work. Although such fertilizer equipment can realize mechanized fertilization, it is necessary to lay guide rails before fertilization. Since there are many rows of grapes, the laying workload is large. Secondly, the guide rails are ground-mounted guide rails, and it is difficult to obtain a good laying level in the grape field. The guide rails also need to be cleaned in real time. These factors will directly affect the working performance of the fertilization equipment. Summary of the invention

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] Examples, such as Figure 1 As shown in FIG10 , the fertilization equipment with adjustable fertilization row spacing for intelligent vineyards provided by the present invention comprises a fertilization device 1, a transmission device 2 is arranged on the power input side of the fertilization device 1, the fertilization device 1 comprises a fertilizer box 11, a feeding port 12 is arranged on one side of the fertilizer box 11, a fertilizer port 13 is arranged on the bottom of the fertilizer box 11, a fertilizer applicator 14 is arranged at the fertilizer port 13, a cylindrical cam transmission shaft 15 is arranged at the center of the fertilizer applicator 14, a guide transmission box 16 is arranged on the top of the fertilizer box 11, a guide rod group 3 is arranged at the center of the guide transmission box 16, the guide rod group 3 comprises a plurality of guide units connected in sequence axially, the guide units cooperate with the cylindrical cam transmission shaft 15 in transmission, the fertilizer box Two through tubes 17 symmetrically distributed about the cylindrical cam drive shaft 15 are arranged inside 11, a transmission rope 21 is arranged inside the through tube 17 and connected to the through tube 17 by screws, and a positioning screw connected to the transmission rope 21 is arranged at a position of the through tube 17 located outside the fertilizer box, a group of unwinding components 22 are arranged at both ends of the transmission rope 21, and the unwinding components 22 are arranged on the portable positioning support device 4. A pair of bidirectional spring clamps 41 that are tensioned with the transmission rope 21 are arranged inside the portable positioning support device 4, and a lifting support component 42 for supporting the guide rod group is arranged on the top of the portable positioning support device 4, and a support bayonet 43 is arranged on the top of the lifting support component 42.

[0033] Specifically, the two unwinding components 22 control the relative lengths of the two transmission ropes 21 in a manner of unwinding one another, and the position of the fertilizer box 11 on the transmission rope 21 is positioned by screws, so the forward and backward movement of the transmission rope 21 can drive the fertilizer box 11 to move forward and backward along the guide track constructed by the guide rod group 3. Specifically, the stepper motor 5 is used to input power to the transmission device 2, drive the unwinding component 22 to control the length of the transmission rope 21, and the fertilizer device 1 can move with the movement of the transmission rope 21; the bidirectional spring clamp 41 can provide a certain tension to the transmission rope 21, and can generate instantaneous braking force when the movement speed of the fertilizer device 1 is uneven, which is conducive to ensuring the uniformity of the movement speed of the fertilizer device 1; at the same time, the guide rod group 3 and the guide transmission box 16 are coordinated to ensure the controllability of the moving direction, and the lifting and rotating movements of the fertilizer applicator 14 can be controlled by the coordination of the guide rod group 3 and the cylindrical cam transmission shaft 15, thereby realizing long-distance motorized fertilization. The use of guide units interlaced front and back can form an effective moving track. The number of guide units can control the working length of the fertilizing device 1, and two portable positioning support devices 4 are used as end supports at both ends of the working length. The working level of the guide rod group 3 is relatively easy to control, avoiding the difficulty of laying tracks on the spot, and can ensure that the fertilizing device 1 performs relatively smooth linear reciprocating movements within the effective working length, thereby ensuring that the fertilization operation has a high efficiency. In addition, on the basis of realizing long-distance mobile fertilization, the preparation work before fertilization is reduced, and it is also more convenient to change lines, and there is no need to frequently change the combined length of the guide rod group 3. Therefore, this device can better adapt to the real-time field operation environment.

[0034] Furthermore, the cylindrical cam transmission shaft 15 provided by the present invention performs a corresponding rotational motion as the fertilizer box 11 moves, and the forward and backward motions of the fertilizer box 11 are related to the actual length of the cylindrical cam transmission shaft 15. For example, when the fertilizer box 11 is in the forward process, the cylindrical cam transmission shaft 15 can be shortened to a certain length under the design of the cam track and the resistance of the fertilizer, and the fertilizer applicator 14 rotates but the fertilizer port 13 is closed, in which case there will be no large-scale fertilizer discharge; on the contrary, when the fertilizer box 11 is in the backward process, the combined length of the cylindrical cam transmission shaft 15 is longer, in which case the bottom of the fertilizer applicator 14 protrudes from the fertilizer port 13, and the fertilizer applicator 14 can discharge the fertilizer from the fertilizer port 13 in a rotating manner while rotating, and the fertilizer is scattered over the distance of the fertilizer box 11 retreating. In this way, by controlling the number of forward and reverse rotations or the relative time of the stepper motor 5, the forward and backward distances of the fertilizer box 11 can be controlled, and the purpose of controlling the fertilization spacing can also be achieved.

[0035] like Figure 4 , Figure 6 and Figure 7As shown, in order to improve the control efficiency of the fertilization action of the device of the present invention, the fertilizer applicator 14 provided by the present invention includes a bottom sealing plate 141, the center of the bottom sealing plate 141 is connected to the cylindrical cam transmission shaft 15, and a volute 142 is arranged on the bottom sealing plate 141, and the cylindrical cam transmission shaft 15 is located at the rotation center of the volute 142. In this way, the bottom sealing plate 141 can rise and block the fertilizer port 13 when the combined length of the cylindrical cam transmission shaft 15 is at the shortest limit, and the bottom sealing plate 141 can fall when the combined length of the cylindrical cam transmission shaft 15 is at the longest limit, so that the fertilizer port 13 is in a relatively open state, and the fertilizer in the fertilizer box 11 can be continuously discharged under the clockwise continuous movement of the volute 142.

[0036] Furthermore, the wheel section of the volute sheet 142 is inclined and its maximum volute diameter is equal to the caliber of the fertilizer port 13. By designing the wheel section of the volute sheet 142 to be an inclined structure, it can play the role of a shovel when moving in the clockwise direction, and continuously shovel the fertilizer to the end of the volute sheet 142, and finally discharge the fertilizer from the fertilizer port 13, and the probability of blockage will be greatly reduced; at the same time, the design of the maximum volute diameter of the volute sheet 142 can ensure that the fertilizer volume on the outermost side of the volute sheet 142 during the ascending process of the bottom sealing plate 141 is not too much to affect the closing efficiency of the fertilizer port 13, and to a certain extent, the smoothness of the forward and backward movement of the fertilizing device 1 can be improved.

[0037] In order to improve the opening and closing control efficiency of the fertilizer port 13, the present invention provides a cylindrical cam transmission shaft 15 with an ingenious design. In order to improve the control performance of the present invention on the fertilizer spacing, from the perspective of the lifting ability of the cylindrical cam transmission shaft 15, the cylindrical cam transmission shaft 15 provided by the present invention is rotatably arranged inside the guide transmission box 16, and the cylindrical cam transmission shaft 15 includes an upper shaft member 151 and a lower shaft member 152. The upper shaft member 151 includes a gear shaft section 151a, and a core shaft 151b is provided at the bottom of the gear shaft section 151a. The core shaft 151b is a stepped A ladder-type structure, the lower half of the core shaft 151b is sleeved with the lower shaft member 152, the outer side surface of the core shaft 151b is provided with a cam guide groove 151c, the cam guide groove 151c extends in a spiral trajectory around the axial surface of the core shaft 151b, the inner wall of the lower shaft member 152 is provided with a cam column 152a that cooperates with the cam guide groove 151c, the bottom of the core shaft 151b is provided with a positioning sleeve 153 that is nested with the guide transmission box 16, the top of the positioning sleeve 153 is used to position the core shaft 151b, and the positioning sleeve 153 is rotatably matched with the lower shaft member 152. Specifically, an assembly groove is provided at the center of the guide transmission box 16 for assembling the gear shaft segment 151a, the core shaft 151b, the lower shaft member 152 and the positioning sleeve 153. The larger diameter shoulder on the core shaft 151b contacts the inner shoulder of the assembly groove, serving as the upper dead point of the core shaft 151b. The positioning sleeve 153 limits the downward direction of the core shaft 151b from the bottom of the assembly groove, serving as the lower dead point of the core shaft 151b. The core shaft 151b and the lower shaft member 152 adopt the cam guide groove 151c and the cam The column 152a is equipped in a manner that different combined lengths can be obtained by relative rotation. When the cam column 152a rotates to the top of the cam guide groove 151c, the combined length of the upper shaft 151 and the lower shaft 152 is the shortest. When the cam column 152a rotates to the bottom of the cam guide groove 151c, the combined length of the upper shaft 151 and the lower shaft 152 is the longest, thereby achieving the purpose of controlling the lifting and lowering of the fertilizer applicator 14, and further achieving the purpose of controlling the opening and closing of the fertilizer port 13.

[0038] like Figure 2 , Figure 5 and Figure 6As shown, in order to improve the movement balance of the fertilizer box 11, the guide transmission box 16 provided by the present invention includes a box-type column 161, and a crossbeam 162 is arranged on the top of the box-type column 161. The outer side of the crossbeam 162 is cylindrical, and a double-conical hole 162a is arranged inside the crossbeam 162. The hole surface of the double-conical hole 162a is provided with a dynamic balance spring 163 extending spirally along the hole surface shape, and a transition arc hole 162b is arranged in the middle of the double-conical hole 162a. The cross section of the transition arc hole 162b is parabolic and movably cooperates with the rod surface of the guide rod group 3. End covers 164 are arranged at both ends of the crossbeam 162, and the end covers 164 can limit the axial position of the dynamic balance spring 163. The minimum spiral diameter of the dynamic balance spring 1632 is interlaced with the guide unit and produces a certain clamping, and the transition arc hole 162b provides a certain tilting margin for the crossbeam 162 to move along the rod surface of the guide rod group 3. In addition, the balancing effect of the dynamic balance spring 163 can make the crossbeam 162 quickly straighten if it shakes when passing through a certain transition node, thereby ensuring the smoothness and stability of the linear reciprocating motion of the fertilizing device 1 along the entire guide rod group 3.

[0039] like Figure 2 and Figure 4 As shown, in order to improve the utilization rate of the guide unit, the guide unit provided by the present invention includes a main rod 31, and the two ends of the main rod 31 are respectively provided with a plug hole 32 and a plug rod 33, and the guide unit is provided with a guide groove 34 axially penetrating the main rod 31, the plug rod 33 and the plug hole 32, and a plurality of fixed teeth 35 are provided on the groove wall of one side of the guide groove 34, and the fixed teeth 35 are meshed with the gear shaft section 151a for transmission. The front and rear two guide units are plugged in through the plug rod 33 and the plug hole 32, and the guide unit at the end adopts a structure in which both of them are plug rods 33, so that it can be clamped at the support bayonet 43. At the same time, each guide unit provides a fixed tooth 35 for the gear shaft section 151a to mesh with it, and the distribution number and milling tooth distance of the fixed teeth 35 are evenly distributed, and the fixed teeth 35 on the same working length path can be connected after the two guide units are plugged in, and then the linear reciprocating motion of the fertilizer device 1 is converted into the lifting motion of the fertilizer applicator 14.

[0040] like Figure 2 , Figure 3 and Figure 4As shown, in order to improve the driving performance of the transmission device 2 on the fertilizing device 1, the unwinding assembly 22 provided by the present invention includes a horizontal unwinding wheel 221, and the horizontal unwinding wheel 221 is provided with two axially parallel wheel grooves 222, and the top of the horizontal unwinding wheel 221 is provided with an upper support member 23 that rotates with it, and the upper support member 23 adopts a cantilever structure to be inserted into the axial hole of the horizontal unwinding wheel 221, and the upper support member 23 is connected to the top surface of the portable positioning support device 4 by bolts, and the bottom of the horizontal unwinding wheel 221 is provided with a transmission bridge 24 that transmits with it, and the transmission bridge 24 is connected to the portable positioning support device 4, and the power input end of the transmission bridge 24 is provided with a stepper motor 5, and the stepper motor 5 is arranged on the side of the portable positioning support device 4, and the side of the portable positioning support device 4 is provided with a mounting groove for mounting the stepper motor 5. The transmission bridge 24 includes a transmission housing and a bevel gear transmission group 244. The stepper motor 5 can input power to the horizontal unwinding wheel 221 while driving the bevel gear transmission group 244. The transmission rope 21 on the same horizontal unwinding wheel 221 is unwound in different wheel grooves 222, which neither interferes with each other nor ensures synchronous movement. In addition, the two transmission ropes 21 form a triangular relationship with the guide rod group 3, which can improve the balance of the movement of the fertilizing device 1.

[0041] Further, the transmission bridge 24 includes a Z-axis section 241 coaxial with the horizontal unwinding wheel 221, an X-axis section 242 is arranged at the bottom of the Z-axis section 241, and a Y-axis section 243 connected to the portable positioning support device 4 is arranged at one end of the X-axis section 242 facing the portable positioning support device 4, and a bevel gear transmission group 244 is arranged inside the Z-axis section 241, the X-axis section 242 and the Y-axis section 243, and the input end of the bevel gear transmission shaft is connected to the stepping motor 5. Among them, the Z-axis section 241, the X-axis section 242 and the Y-axis section 243 provide corresponding transmission sealing conditions for the bevel gear transmission group 244, and provide corresponding shaft end support, such as the ends of the Z-axis section 241, the X-axis section 242 and the Y-axis section 243 are all provided with bearings or bearings that can support the shaft end of the bevel gear transmission group 244. The transmission bridge 24 adopts the form of one-end input, that is, the stepper motor 5 inputs power from the Y-axis section 243 of the transmission bridge 24, and the bevel gear transmission group 244 arranges a group of bevel gears at the T-node position of the Y-axis section 243 and the X-axis section 242, and the direction of the force changes once; the bevel gear transmission group 244 arranges a group of bevel gears at the intersection node position of the X-axis section 242 and the Z-axis section 241, and the direction of the force changes again, and the terminal output shaft of the bevel gear transmission group 244 is connected to the horizontal unwinding wheel 221 through a key. In this way, the transmission bridge 24 not only plays the role of supporting the horizontal unwinding wheel 221, but also plays the role of transmitting the driving force, and ensures that the device has a better overall effect, small space occupation, and high space utilization.

[0042] like Figure 1 , 2As shown in FIGS. 3 and 6 , the portable positioning support device 4 includes a trouser-shaped base 44, and multifunctional handles 45 are rotatably provided on both sides of the bottom of the trouser-shaped base 44. The multifunctional handles 45 can be supported on the ground by flipping and adjusting to prevent the portable positioning support device 4 from tipping over. The multifunctional handles 45 can be flipped to the neutral plane of the portable positioning support device 4 by flipping and adjusting to allow people to carry and transfer the portable positioning support device 4. The multifunctional handle 45 is connected to the trouser-shaped base 44 by a hinge, and the hinge adopts an angle-adjustable hinge, so that a certain unfolding angle can be maintained when the multifunctional handle 45 is in the unfolded state, so as to better support the device on the ground of the vineyard. The multifunctional handle 45 can not only play the role of preventing tipping over, but also play the role of a handle, and is cleverly designed and highly practical.

[0043] In order to conveniently improve the height of the fertilizer connection, the present invention provides a lifting component to adjust the actual height of the guide rod group 3. Specifically, the lifting support component 42 includes four screws 421, the bottom of the screw 421 is connected to the support hole set on the trouser-shaped base 44, the screw 421 is sleeved with a spring 422, the top of the spring 422 is provided with a top seat 423 that penetrates and cooperates with the screw 421, the top of the screw 421 is provided with an adjusting nut 424 for adjusting the height of the top seat 423, and the support bayonet 43 is provided on the top of the top seat 423. Since the transmission rope 21 has a certain deflection, it mainly plays a driving role on the fertilizer device 1, and the specific height of the guide rod group 3 on the lifting support component 42 can be reflected as the height of the fertilizer device 1.
