Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an orchard pit digging and fertilizing integrated machine. Background Art

[0002] Orchard planting occupies an important position in agricultural production, and the cultivation of seedlings is a key link in orchard management. Fertilization is an important measure to promote the healthy growth of seedlings and improve fruit yield and quality. In orchard fertilization operations, traditional fertilization on the surface of the soil layer makes it difficult for fertilizers to penetrate into the soil and be effectively absorbed by the roots of seedlings. Therefore, it is necessary to dig pits in the soil layer and break the soil layer to improve the soil structure, increase the contact area between fertilizers and roots, and improve fertilizer utilization. However, orchards are usually planted in batches, and the distance between fruit trees is roughly the same, but as the seedlings grow, the growth space and nutritional conditions they require change. Larger seedlings not only have larger plant spacing, but also require more fertilizer to meet growth needs. At the same time, they also require deeper soil layers to be trimmed to accommodate their developed root systems. At present, orchard fertilization operations rely on manual labor. Manual pit digging and fertilization are difficult to ensure the consistency of pit depth, width and spacing, and are prone to uneven fertilization, affecting the uniformity of seedling growth and the overall orchard yield.

[0010] Furthermore, a ratchet structure is provided between the connecting disk and the transmission wheel, and when the reset toothed disk drives the transmission wheel to rotate, the connecting disk is in a stationary state.

[0011] Furthermore, a fertilizer storage box is arranged on the bracket, and a fertilizer storage cavity is provided inside the fertilizer storage box, and fertilizer is stored in the fertilizer storage cavity; a fertilizer application piece is arranged on the fertilizer storage box, and the fertilizer application amount of the fertilizer application piece can be determined according to the movement amount of the drilling auger on the bracket.

[0012] Furthermore, the fertilization component includes a fertilization pipe, which slides through the fertilizer storage box. A plurality of fertilization holes are provided on the fertilization pipe. The end of the fertilization pipe is always in a blocked state.

When it is necessary to apply fertilizers to the fruit trees in the orchard, the support is moved into the orchard. When the support is pushed toward the fruit trees, the rotating wheel on the support rotates. In the initial state, the perforating auger is at the top of the support. At this time, the perforating auger does not hinder the movement of the support in the orchard. When the support moves to the periphery of the fruit trees, the rotating wheel stops rotating. The kinetic energy generated during the rotation of the rotating wheel drives the perforating auger to start rotating, and the perforating auger moves from top to bottom on the support during the rotation of the perforating auger. As the drilling auger moves on the bracket, it gradually drills holes on the ground. The more times the rotating wheel rotates, the deeper the hole drilled by the drilling auger on the ground. After drilling a hole in one of the saplings, fertilizer is applied to the hole on the ground, and the reset part is used to drive the drilling auger to reset, and then the bracket is driven to move to the next fruit tree. Inside the orchard, the larger saplings have a larger spacing between them. In the process of driving the bracket to move, the more times the rotating wheel rotates, the deeper the hole drilled by the drilling auger on the ground. The distance between two adjacent fruit trees is associated with the drilling depth to ensure uniform fertilization of the fruit trees in the orchard. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figures 1 to 4As shown, an orchard pit digging and fertilizing integrated machine provided by an embodiment of the present invention includes a bracket 110, a perforating auger 130, a transmission member and a reset member.

[0023] The bracket 110 is rotatably provided with a rotating wheel 120, and a plurality of rotating wheels 120 are provided, and the plurality of rotating wheels 120 jointly support the bracket 110, and the plurality of rotating wheels 120 simultaneously contact the ground, and when the bracket 110 moves relative to the ground, the rotating wheels 120 rotate. The bracket 110 is provided with a pushing handle, so that the staff can push the bracket 110 conveniently.

[0024] The drilling auger 130 is arranged on the bracket 110. The drilling auger 130 is slightly conical. The drilling auger 130 can rotate and move up and down on the bracket 110. When the drilling auger 130 rotates on the bracket 110, the drilling auger 130 moves downward on the bracket 110, and the drilling auger 130 gradually drills into the ground, thereby forming a hole on the ground. The drilling auger 130 is initially set to be at the top of the bracket 110, and the drilling auger 130 does not hinder the movement of the bracket 110 on the ground.

[0025] The transmission member is arranged between the rotating wheel 120 and the drilling auger 130. The rotating wheel 120 can generate kinetic energy when it rotates, and the transmission member can store the power generated when the rotating wheel 120 rotates. When the rotating wheel 120 stops rotating, the transmission member releases the stored kinetic energy, and the transmission member will drive the drilling auger 130 to move from top to bottom on the bracket 110. When the drilling auger 130 moves from top to bottom on the bracket 110, the drilling auger 130 is in a rotating state, thereby realizing the action of the drilling auger 130 drilling holes on the ground. It is easy to understand that the amount of energy generated by the rotating wheel 120 when it rotates determines the depth of the holes drilled by the drilling auger 130 on the ground.

[0026] The reset member is used to drive the drilling auger 130 to move from bottom to top on the bracket 110. After drilling a hole in one place, the reset member is first used to drive the drilling auger 130 to reset, and fertilizer is added into the hole 1. After fertilization, the staff bury the hole and move the bracket 110 to the vicinity of the next fruit tree again.

[0027] The orchard digging and fertilizing integrated machine of the present invention moves the support 110 into the orchard when fertilizing the fruit trees in the orchard is needed. When the support 110 is pushed close to the fruit trees, the rotating wheel 120 on the support 110 rotates. In the initial state, the punching auger 130 is at the top of the support 110. At this time, the punching auger 130 does not hinder the movement of the support 110 in the orchard. When the support 110 moves to the periphery of the fruit trees, the rotating wheel 120 stops rotating. The kinetic energy generated during the rotation of the rotating wheel 120 drives the punching auger 130 to start rotating, and during the rotation of the punching auger 130, the punching auger 130 moves from top to bottom on the support 110. During the movement on 10, the punching auger 130 gradually punches holes on the ground. The more circles the rotating wheel 120 rotates, the deeper the holes punched on the ground by the punching auger 130. After drilling holes around one of the saplings, fertilizer is applied to the hole on the ground, and the reset member is used to drive the punching auger 130 to reset, and then the drive bracket 110 moves to the next fruit tree. Inside the orchard, the larger saplings have a larger spacing between them. During the movement of the driving bracket 110, the more circles the rotating wheel 120 rotates, the deeper the holes punched on the ground by the punching auger 130. The distance between two adjacent fruit trees is associated with the drilling depth to ensure uniform fertilization of the fruit trees in the orchard.

[0028] In one embodiment, the drilling auger 130 includes a support sleeve 140, which is used to prevent the drilling auger 130 from deforming. In this embodiment, the support sleeve 140 is a hollow cylindrical shape. When the drilling auger 130 drills holes on the ground, the drilling auger 130 can stir the soil on the ground. In order to prevent the drilling auger 130 from deforming during the drilling process, the support sleeve 140 is installed inside the drilling auger 130, thereby improving the strength of the drilling auger 130. A limit plate 150 is rotatably arranged on the bracket 110, and the limit plate 150 is used to prevent the support sleeve 140 from moving on the bracket 110 in the initial state. Under the action of the limit plate 150, the drilling auger 130 will not contact the soil on the ground in the initial state, thereby reducing the probability that the drilling auger 130 hinders the bracket 110 from moving on the ground. When the bracket 110 moves to the position where drilling and fertilizing are required, the limit plate 150 removes the obstruction of the support sleeve 140. At this time, the transmission member transmits the kinetic energy generated by the rotating wheel 120 during the rotation process to the drilling auger 130, so that the drilling auger 130 moves underground in a rotating state.

[0029] In one embodiment, a rotating hinge is provided between the limit plate 150 and the bracket 110, and the rotating hinge has a first state of opening and a second state. When the rotating hinge is in the second state, the limit plate 150 is in a state of hindering the support sleeve 140 from moving on the bracket 110. Specifically, when the rotating hinge is in the second state, the limit plate 150 is in a horizontal state. When the rotating hinge is in the first state, the limit plate 150 is in a state of unblocking the support sleeve 140 from moving on the bracket 110. Specifically, when the rotating hinge is in the first state, the limit plate 150 is in a vertical state. The staff can manually adjust the first state and the second state of the rotating hinge. In the initial state, the rotating hinge is in the second state. When the bracket 110 stops moving, the staff switches the rotating hinge from the second state to the first state.

[0030] In one embodiment, the transmission member includes a first transmission unit and a second transmission unit, the second transmission unit includes a transmission shaft 160, a transmission wheel 170, a driven wheel 180 and a transmission torsion spring 190, the driven wheel 180 is rotatably connected to the bracket 110, and the axis of the driven wheel 180 is vertically arranged. The transmission shaft 160 is rotatably connected to the support sleeve 140, the lower end of the transmission shaft 160 is connected to the upper end of the support sleeve 140, the transmission shaft 160 is slidably connected to the bracket 110, and the axis of the transmission shaft 160 is vertically arranged. The transmission wheel 170 is rotatably connected to the bracket 110, the transmission wheel 170 is coaxially arranged with the transmission shaft 160, the transmission wheel 170 is coaxially sleeved on the outside of the transmission shaft 160, and the inner side wall of the transmission wheel 170 and the outer side wall of the transmission shaft 160 are both provided with thread grooves, so that the transmission wheel 170 is threadedly engaged with the transmission shaft 160. A telescopic rod 210 is connected between the transmission wheel 170 and the support sleeve 140, wherein a plurality of telescopic rods 210 are provided, and the plurality of telescopic rods 210 are evenly arranged around the circumference of the transmission wheel 170, and the telescopic rods 210 are arranged vertically, and the lower end of the telescopic rod 210 is connected to the support sleeve 140, and the upper end of the telescopic rod 210 is connected to the transmission wheel 170, and when the transmission wheel 170 rotates, the support sleeve 140 rotates synchronously with the transmission wheel 170. The transmission torsion spring 190 is provided between the driven wheel 180 and the transmission wheel 170, and in the initial state, the limit plate 150 is in a state of hindering the support sleeve 140 from moving downward, and when the support sleeve 140 cannot move downward, the transmission wheel 170 cannot rotate on the transmission shaft 160. The first transmission unit is used to transmit the rotation of the rotating wheel 120 to the rotation of the driven wheel 180. When the rotating wheel 120 rotates, the driven wheel 180 rotates synchronously. During the rotation of the driven wheel 180, the transmission torsion spring 190 gradually accumulates force. When the bracket 110 stops moving, the limit plate 150 removes the obstacle for the support sleeve 140 to move downward. At this time, the driven wheel 180 stops rotating, and the transmission torsion spring 190 gradually releases force. During the process of releasing force, the transmission torsion spring 190 drives the transmission wheel 170 to rotate. When the transmission wheel 170 rotates, it drives the support sleeve 140 to rotate. At the same time, the transmission shaft 160 moves vertically downward, so that the support sleeve 140 undergoes a combined downward and rotational movement, and the drilling auger 130 fixedly connected to the support sleeve 140 drills holes in the ground.

[0031] In one embodiment, the first transmission unit includes a transmission roller 220 and a reversing wheel 230, and the rotating wheel 120 is coaxially fixedly connected with a rotating shaft, and the rotating shaft is in a horizontal state. The transmission roller 220 is rotatably connected to the bracket 110, and the transmission roller 220 is in a vertical state. Two reversing wheels 230 are provided, one of which is coaxially fixedly connected to the transmission roller 220, and the other is coaxially fixedly connected to the rotating shaft. Both reversing wheels 230 are bevel gears, and the two reversing wheels 230 are always meshed. When the rotating wheel 120 rotates, the transmission of the two reversing wheels 230 causes the transmission roller 220 to rotate. A fixed gear is fixedly provided on the transmission roller 220, and a ring gear is provided on the outer wall of the driven wheel 180. The fixed gear is always meshed with the ring gear. When the transmission roller 220 rotates, the driven wheel 180 rotates synchronously.

[0032] In one embodiment, the reset member includes a reset toothed disc 240 and a reset motor 250. The reset toothed disc 240 is coaxially fixedly connected to the transmission wheel 170. The reset motor 250 is fixedly connected to the bracket 110. The reset motor 250 can drive the reset toothed disc 240 to rotate. Specifically, a driving gear is fixedly arranged on the power output shaft of the reset motor 250. The driving gear is always engaged with the reset toothed disc 240. When the reset motor 250 is started, the reset toothed disc 240 rotates. A connecting disc is coaxially arranged on the transmission wheel 170. The connecting disc is arranged at the upper end of the transmission wheel 170. The connecting disc is unidirectionally connected to the transmission wheel 170. The connecting disc is fixedly connected to the transmission torsion spring 190. When the driven wheel 180 rotates, the connecting disc and the transmission wheel 170 remain stationary, so that the transmission torsion spring 190 accumulates force. When the drive motor is started, the connecting disc drives the transmission wheel 170 to rotate. At this time, the connecting disc remains stationary, thereby preventing the driven wheel 180 from rotating in the opposite direction.

[0033] In one embodiment, a ratchet structure is provided between the connecting disk and the transmission wheel 170. When the reset toothed disk 240 drives the transmission wheel 170 to rotate, the connecting disk is in a stationary state. Specifically, the ratchet structure includes a ratchet disk and an elastic pawl. The ratchet disk is provided on the connecting disk, and the elastic pawl is provided on the transmission wheel 170. The elastic pawl is engaged with the ratchet disk. The cooperation between the elastic pawl and the ratchet disk enables one-way rotation between the connecting disk and the transmission wheel 170.

[0034] In one embodiment, a fertilizer storage box 260 is provided on the support 110. The interior of the fertilizer storage box 260 is hollow. The hollow chamber inside the fertilizer storage box 260 is a fertilizer storage chamber. The upper end surface of the fertilizer storage box 260 is provided with a feeding port connecting the external environment and the fertilizer storage chamber. The fertilizer storage box 260 is provided with a blocking plate, which can block or open the feeding port. The staff can transport fertilizers into the fertilizer storage chamber through the feeding port, and the fertilizer storage chamber can store fertilizers. The fertilizer storage box 260 is provided with a fertilizer application member, which can transport the fertilizer in the fertilizer storage chamber to the outside. The amount of fertilizer applied by the fertilizer application member can be determined according to the movement amount of the punching auger 130 on the support 110. Furthermore, the movement amount of the punching auger 130 on the support 110 determines the punching depth. The higher the punching depth, the greater the distance between the fruit trees, and the more fertilizers the fruit trees need, thereby achieving precise fertilization of the fruit trees.

[0035] In one embodiment, the fertilizer application member includes a fertilizer application pipe 270, which slides through the fertilizer storage box 260, is always in a vertical state, and both ends of the fertilizer application pipe 270 are in a blocked state. The upper end of the fertilizer application pipe 270 is above the fertilizer storage box 260, and the lower end of the fertilizer application pipe 270 is below the fertilizer storage box 260. The fertilizer application pipe 270 is provided with a plurality of fertilizer application holes 271, and the plurality of fertilizer application holes 271 are initially set to be in the fertilizer storage cavity, and the fertilizer in the fertilizer storage cavity can enter the inside of the fertilizer application pipe 270 through the fertilizer application holes 271. When the fertilizer application pipe 270 slides on the fertilizer storage box 260, part of the fertilizer application pipe 270 can move to the bottom of the fertilizer storage box 260, so that the fertilizer in the fertilizer storage cavity is fertilized outward through the fertilizer application holes 271.

[0036] In one embodiment, the fertilizing member also includes a transmission plate 280, one end of the transmission plate 280 is fixedly connected to the upper end of the fertilizing tube 270, and the other end of the transmission plate 280 is fixedly connected to the upper end of the transmission shaft 160. When the transmission shaft 160 moves in the vertical direction, the transmission shaft 160 is driven by the transmission plate 280 to make the fertilizing tube 270 move synchronously.
