DETAILED DESCRIPTION

[0047] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0048] The following description sets forth specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0049] like Figure 1 As shown, the multifunctional fertilizer mixing machine described in the utility model includes a supporting platform 2, a solid fertilizer feeding device, a liquid fertilizer feeding device, a fertilizer mixing device, and a fertilizer discharging and packaging device. The solid fertilizer feeding device, the liquid fertilizer feeding device, the fertilizer mixing device, and the fertilizer discharging and packaging device are all arranged on the supporting platform. The solid fertilizer feeding device and the liquid fertilizer feeding device are arranged at the feeding port of the fertilizer mixing device. The fertilizer discharging and packaging device is arranged at the discharging port of the fertilizer mixing device. The front part of the supporting platform 1 is connected to a traction frame 1, and the traction frame 1 is connected to the power mechanism in front. The bottom surface of the supporting platform 2 is provided with a plurality of wheels 21, and through the wheels 21, the action of the power mechanism can drive the multifunctional fertilizer mixing machine to realize walking.

[0050] The fertilizer stirring device comprises a stirring tank 8, the axis of which is arranged in a horizontal direction. A feeding port 22 is arranged at one end of the stirring tank 8, a discharging port 31 is arranged at one end of the stirring tank 8, a solid fertilizer feeding device and a liquid fertilizer feeding device are arranged at the feeding port 22, and a fertilizer discharging and packaging device is arranged at the discharging port.

[0051] In this embodiment, the tank body of the mixing tank 8 includes three parts: a cylindrical tank body located in the middle, and conical tank bodies located on both sides of the cylindrical cavity, one side of the two conical tank bodies is connected to the cylindrical tank body, and the other side of the two conical tank bodies is respectively provided with openings. A power mechanism capable of rotating the mixing tank 8 is provided on the annular outer side of the cylindrical tank body.

[0052] The power mechanism includes a motor 16, a driving gear 15 and a driven gear 12, wherein the motor 16 is fixed to the bottom surface of the support platform 2, the output shaft of the motor 16 is connected to the input shaft of the reduction box 14, the output shaft of the reduction box 14 is drivingly connected to the driving gear 15, and the driving gear 15 and the driven gear 12 are meshed with each other. The driven gear 12 is fixed to the annular outer side of the cylindrical tank.

[0053] During the operation of the motor 16 , the driving gear 15 is driven to rotate, and the driven gear 12 and the stirring tank 8 are driven to rotate through the mutual meshing between the driving gear 15 and the driven gear 12 .

[0054] In order to ensure the stability of the mixing tank 8 during rotation, in this embodiment, the driven gear 12 is arranged in the middle of the mixing tank 8, and an annular track 9 is respectively provided on both sides of the driven gear 12, and the track 9 is fixed on the annular outer side of the mixing tank 8. The track 9 is in rolling contact with a pair of safety limit rollers 11 and a pair of rollers 13 respectively. Each pair of safety limit rollers 11 includes two safety limit rollers 11 arranged radially symmetrically with respect to the track 9, and the safety limit rollers 11 are in rolling contact with the track 9. Each pair of rollers 13 includes two rollers 13 arranged radially symmetrically with respect to the track 9, and the rollers 13 are in rolling contact with the track 9. The safety limit roller 11 is located above the roller 13. The rolling contact between the safety limit rollers and the rollers 13 and the track 9, and their support, play a role in limiting the rotating mixing tank 8.

[0055] like Figure 3 As shown, a plurality of auger blades are arranged at intervals inside the tank body of the mixing tank 8, and all the auger blades are inclined in the same direction and at the same inclination angle. The auger blades are fixed on the inner surface of the cylindrical tank body and the conical tank body with the discharge port, and no auger blades are arranged on the inner surface of the cylindrical tank body with the feed port.

[0056] When the mixing tank 8 rotates in the direction opposite to the inclination direction of the auger blades, the auger blades play a stirring role, achieving full stirring of the solid fertilizer and liquid fertilizer entering the mixing tank, and the auger blades can effectively prevent the fertilizer from adhering to the bottom of the tank body. When the mixing tank 8 rotates in the same direction as the inclination direction of the auger blades, the auger blades play a guiding role, gradually transferring the fully stirred fertilizer along the auger blades to the discharge port, achieving automatic discharge of the stirred fertilizer.

[0057] The solid fertilizer is transported and fed into the mixing tank through the solid fertilizer feeding device. The solid fertilizer feeding device includes a conveyor belt 18 and a receiving hopper 24. The receiving hopper 24 is located at the feeding port of the fertilizer mixing device. The bottom of the receiving hopper 24 is inclined, that is, the end of the bottom of the receiving hopper away from the fertilizer mixing device is higher than the end close to the fertilizer mixing device, so that the fertilizer falling into the receiving hopper can automatically slide along the bottom surface of the receiving hopper into the fertilizer mixing device. In this embodiment, the receiving hopper 24 is placed on a support frame.

[0058] The receiving hopper 24 is located below one end of the conveyor belt 18, and the other end of the corresponding conveyor belt 18 is fixedly connected to the fertilizer box 17. The conveyor belt 18 is connected to the support frame through a conveyor belt lifting mechanism, and the conveyor belt 18 and the fertilizer box 17 can be slid and lifted upward along the conveyor belt slideway 7 as a whole through the conveyor belt lifting mechanism, and finally the lowest end of the solid fertilizer feeding device is moved to the top of the support platform 2, so as to prevent the conveyor belt from contacting or colliding with the ground or the conveyor belt and the equipment outside the support platform during the traction and walking of the machine.

[0059] The conveyor belt 18 is arranged on the conveyor belt support frame 35. The conveyor belt 18 is wound around the transmission shafts at both ends, and the transmission shafts at both ends include a passive transmission shaft and an active transmission shaft, and the passive transmission shaft and the active transmission shaft are respectively rotatably connected to the conveyor belt support frame. The active transmission shaft is transmission-connected to the output shaft of the speed regulating motor 20. In the present embodiment, the transmission connection mode between the active transmission shaft and the output shaft of the speed regulating motor 20 is chain transmission. The speed regulating motor 20 is arranged on a motor fixing frame, and the motor fixing frame is fixedly connected to the conveyor belt support frame 35. In the present embodiment, baffles are provided on both sides of the conveyor belt 18 along the transmission direction, and the baffles are fixedly connected to the conveyor belt support frame 35, and the baffles can prevent the fertilizer on the conveyor belt 18 from falling during the transmission process.

[0060] The box body of the fertilizer box 17 is fixedly connected to the baffles on both sides of the conveyor belt, the bottom of the fertilizer box 17 is open, and there is a gap between the bottom of the fertilizer box 17 and the conveyor belt, and the solid fertilizer in the fertilizer box 17 can fall onto the transmission belt 18 through the opening at the bottom of the fertilizer box 17. In this embodiment, a number of partitions are evenly spaced on the conveyor belt 18 to ensure that the solid fertilizer slides down along the conveyor belt when being conveyed upward along the inclined conveyor belt 18.

[0061] After solid fertilizer is loaded into the fertilizer box 17, the fertilizer in the fertilizer box 17 falls from the opening at the bottom of the fertilizer box 17 onto the conveyor belt 18, and the fertilizer is continuously conveyed toward the receiving hopper as the conveyor belt 18 rotates. When the fertilizer is conveyed to the top of the receiving hopper, as the conveyor belt 18 turns over, the fertilizer on the conveyor belt falls into the receiving hopper 24 under the action of its own gravity, and then slides into the fertilizer stirring device along the inclined bottom surface of the receiving hopper.

[0062] In order to ensure the tension of the conveyor belt and prevent the conveyor belt from deflecting, the transmission shaft at one end of the conveyor belt and the transmission belt support frame 25 can slide relative to each other. Figure 4 As shown, the two ends of the passive transmission shaft 37 are connected to the bearing seat 36 through bearings, and the bearing seat 36 can be slidably connected to the conveyor belt support frame 35. The bearing seat 36 and the conveyor belt support frame 35 are connected by bolts: when the bolts are tightened, the fixed connection between the bearing seat 36 and the conveyor belt support frame 35 can be achieved, and the relative position between the bearing seat 36 and the conveyor belt support frame 35 is fixed; when the bolts are loosened, the bearing seat 36 and the conveyor belt support frame 35 can slide relative to each other, and the relative position between the bearing seat 36 and the conveyor belt support frame 35 is adjustable. The two bearing seats 36 are respectively fixedly connected to one end of the adjustment screw 19, and the other ends of the corresponding two adjustment screws 19 are respectively threadedly connected to the ends of the conveyor belt support frame 35. At the same time, the adjustment screws 19 on both sides are rotated, and the axial movement is generated during the rotation of the adjustment screws 19, thereby driving the bearing seat 36 to slide relative to the conveyor belt support frame 35. At this time, the position of the passive transmission shaft 37 can be adjusted, thereby realizing the adjustment of the tension of the conveyor belt.

[0063] The conveyor belt lifting mechanism includes a conveyor belt slideway 7 and a hand-cranked lifting locking pulley 23. The conveyor belt slideway 7 is located outside the conveyor belt support frame 35, and the conveyor belt support frame 35 can slide on the conveyor belt slideway 7. The conveyor belt slideway 7 is fixed on the top of the support frame. The hand-cranked lifting locking pulley 23 is located on the support frame below the conveyor belt 18. One end of the steel wire rope 38 is connected to the conveyor belt support frame 35 on the feeding end side of the conveyor belt, and the other end of the steel wire rope 38 is wound around the hand-cranked lifting locking pulley 23. Turning the crank to rotate the hand-cranked lifting locking pulley 23, the steel wire rope 38 will drive the conveyor belt support frame 35 to slide along the conveyor belt slideway 7 during the process of the hand-cranked lifting locking pulley 23 winding or releasing the steel wire rope, so that the distance between the conveyor belt and the ground changes.

[0064] When the hand-cranked lifting locking pulley 23 rotates and the steel wire rope is wound onto the hand-cranked lifting locking pulley 23, the length of the steel wire rope 38 between the hand-cranked lifting locking pulley 23 and the conveyor belt becomes shorter, and the steel wire rope 38 drives the conveyor belt support frame 35 to slide upward along the conveyor belt slideway 7, and the distance between the conveyor belt and the ground becomes larger. At this time, when the power mechanism drives the machine forward, the conveyor belt will not contact or collide with the ground, which plays a protective role for the machine. When the machine moves to the work site where the fertilizer needs to be stirred, the hand-cranked lifting locking pulley 23 rotates to release the steel wire rope from the hand-cranked lifting locking pulley 23, and the length of the steel wire rope 38 between the hand-cranked lifting locking pulley 23 and the conveyor belt becomes longer, and the conveyor belt 18 slides downward along the conveyor belt slideway 7 under the action of its own gravity until the steel wire rope is in a taut state and pulls the conveyor belt to stop moving.

[0065] The liquid fertilizer feeding device includes a liquid fertilizer box 3 and a spray rod 34, and the spray rod 34 extends into the mixing tank 8 through the feeding port of the fertilizer mixing device. The liquid fertilizer box 3 is connected to the spray rod 34 through a connecting pipeline, and a flow meter 5 and a pressure regulator 6 are provided on the connecting pipeline, wherein the flow meter 5 is used to accurately measure the flow of the liquid fertilizer, and the pressure regulator 6 is used to adjust the pressure of the liquid fertilizer. The pump 3 is started to feed the liquid fertilizer in the liquid fertilizer box 3 into the spray rod 34 through the connecting pipeline. A plurality of spray holes are provided at intervals at the bottom of the spray rod 34 to ensure that the liquid fertilizer can be evenly sprayed on the solid fertilizer.

[0066] The fertilizer discharging and packaging device is used to collect and package the fully stirred fertilizer flowing out of the discharging port. Figure 2 and Figure 3 As shown, the fertilizer discharging and packaging device includes a fertilizer storage box 30, a fertilizer lifting auger 32, a fertilizer discharging motor 26 and a portable bag sewing machine 25. The fertilizer storage box 30 is located on a support platform below the discharging port 31. The fertilizer lifting auger 32 is connected to the fertilizer discharging motor 26. During the operation of the fertilizer discharging motor 26, the fertilizer in the fertilizer storage box 30 is lifted to the fertilizer discharging port 29 by the fertilizer lifting auger 32. A bag support frame 28 is provided below the fertilizer discharging port 29, and the bag support frame 28 is used to support the packaging bag so that the fertilizer flowing out of the fertilizer discharging port 29 can fall into the packaging bag.

[0067] The bag support frame 28 is placed on the electronic scale 27, and the fertilizer in the packaging bag can be directly weighed by the electronic scale 27. When the packaging bag is full of fertilizer, the fertilizer discharging motor 26 is turned off, and the bag opening of the packaging bag is sutured and sealed by the portable bag sewing machine 25. The portable bag sealing machine 25 can be placed on the supporting platform.

[0068] The working process of the machine is as follows: the machine is connected to a power mechanism, and under the traction of the power mechanism, the machine is moved to a location where fertilizer mixing is required, at which time the hand-operated lifting locking pulley 23 in the conveyor belt lifting mechanism rotates to reel in the steel wire rope, at which time the length of the steel wire rope becomes shorter, causing the transmission belt to move upward along the transmission belt slideway 7, and the distance between the conveyor belt and the ground becomes larger.

[0069] When the machine moves to the designated location, the hand-operated lifting locking pulley 23 releases the wire rope, and the length of the wire rope becomes longer. The conveyor belt moves downward along the conveyor belt slideway 7 under the action of its own gravity, and the conveyor belt moves to a position close to the ground. Solid fertilizer is injected into the fertilizer box 17, and the solid fertilizer in the fertilizer box 17 falls onto the conveyor belt 18 through the opening at the bottom thereof, and the solid fertilizer is continuously transported toward the receiving hopper through the rotation of the conveyor belt 18. When the solid fertilizer is transported to the top of the conveyor belt, as the conveyor belt continues to rotate, the solid fertilizer falls into the receiving hopper 24 under the action of its own gravity, and then the solid fertilizer slides along the inclined bottom surface of the receiving hopper 24 into the mixing tank 8. When a certain proportion of liquid fertilizer is required, the liquid fertilizer in the liquid fertilizer box 3 is continuously pumped into the spray bar 34 by the pump 4 and evenly sprayed on the solid fertilizer.

[0070] The motor 16 is activated to drive the driving gear 15 to rotate, thereby driving the driven gear 12 and the mixing tank 8 fixedly connected to the driven gear 12 to rotate. Under the stirring action of the auger blades 33, sufficient stirring between the solid fertilizer and the liquid fertilizer can be achieved.

[0071] After the fertilizer is fully stirred, the motor 16 moves in the reverse direction, thereby driving the stirring tank 8 to rotate in the reverse direction. At this time, under the guidance of the auger blade 33, the fully stirred fertilizer in the stirring tank 8 is transported to the discharge port 31. The fertilizer flowing out of the discharge port 31 falls directly into the fertilizer storage box 30 under the action of gravity. The fertilizer discharge motor 26 drives the lifting auger 32 to move, and the lifting auger 32 lifts and outputs the fertilizer in the fertilizer storage box 30, and drops it into the packaging bag below through the fertilizer discharge port 29. After the packaging bag is filled with fertilizer, the bag mouth of the packaging bag is sealed.
