DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-11 As shown, an automatic fertilizer filling device includes a workbench 1, a bag-holding mechanism 2, a filling mechanism 3, a removing mechanism 4 and a conveying mechanism 5. A rotatable turntable 11 is installed on the workbench 1; the bag-holding mechanism 2 is installed on the turntable 11, and the bag-holding mechanism 2 includes a base 21, and two bag-holding frames 22 installed on both sides of the base 21 and capable of moving toward or away from each other; the filling mechanism 3 includes a hopper 31, and a screw feeder 32 installed below the hopper 31; the removing mechanism 4 includes two grabbing claws 41 that are arranged oppositely and can move toward or away from each other; the conveying mechanism 5 includes a conveyor belt 51 arranged on one side of the turntable 11; the bag-holding mechanism 2 can rotate with the turntable 11, and can rotate to the outlet of the screw feeder 32 and below the grabbing claw 41 in turn, and the grabbing claw 41 can be raised and lowered and reciprocated between the turntable 11 and the conveyor belt 51.

[0040] The filling mechanism 3 and the removing mechanism 4 are fixed to the side of the workbench 1 through the supporting frames 6 respectively.

[0041] In order to improve work efficiency, four bag-supporting mechanisms 2 are provided and are evenly distributed in a ring shape on the rotating disk 11 , while two filling mechanisms 3 are provided so as to simultaneously fill two fertilizer bags 7 .

[0042] Specifically, during the filling process, the two filling mechanisms 3 are opposite to the two bag-supporting mechanisms 2 and perform filling at the same time, while the removal mechanism 4 can be opposite to one bag-supporting mechanism 2 to realize the removal of the filled fertilizer bag 7, and the remaining bag-supporting mechanism 2 can facilitate the staff to place the empty bag.

[0043] In addition, driven by the turntable 11, the bag-supporting mechanism 2 moves one station at a time. Through the arrangement of the two filling mechanisms 3, when the bag-supporting mechanism 2 moves to the first filling mechanism 3, half a bag of fertilizer can be filled into the fertilizer bag 7. When it moves to the second filling mechanism 3, the fertilizer is filled up again. This operation is convenient and quick.

[0044] When the filling equipment is working, the turntable 11 needs to drive each bag-supporting mechanism 2 to switch the working position. In order to realize the rotation of the turntable 11, a rotating motor 12 is installed inside the workbench 1, and the rotating motor 12 drives the turntable 11 to rotate through the gear box 13.

[0045] In order to fix the bag opening of the fertilizer bag 7 , a bag support clamp 23 capable of horizontal movement is installed at the inner upper end of the bag support frame 22 , and a hook 24 is provided at the end of the bag support clamp 23 .

[0046] Specifically, two bag supporting clamps 23 are installed on each bag supporting frame 22, and a horizontal waist-shaped hole 25 is provided on the bag supporting frame 22. The bag supporting clamps 23 are installed in the waist-shaped hole 25 by bolts, and the positions of the bag supporting clamps 23 can be appropriately adjusted as needed.

[0047] The hook 24 can hook the bag mouth of the fertilizer bag 7, thereby fixing the bag mouth so that it cannot fall off from the bag support card 23. The bag mouth of the fertilizer bag 7 can be opened into a rectangular shape by the four bag support cards 23 on the two bag support frames 22, thereby facilitating the filling of fertilizer.

[0048] The two bag-holding frames 22 need to move back to back in order to open the bag opening of the fertilizer bag 7. In order to achieve the movement of the bag-holding frames 22, the bag-holding mechanism 2 also includes a rotary cylinder 26 installed under the base 21. A linkage disk 27 is installed on the rotating assembly of the rotary cylinder 26. Two centrally symmetrical connecting plates 28 are hinged on the linkage disk 27, and the outer ends of the two connecting plates 28 are hinged to the two bag-holding frames 22 respectively.

[0049] Specifically, a connecting hole 29 is provided at the bottom of the bag-supporting frame 22 , and the outer end of the connecting plate 28 is hinged in the connecting hole 29 .

[0050] In order to realize the relative or opposite movement of the two bag-supporting frames 22 , a guide hole 210 is provided on the lower surface of the base 21 , a linear bearing 211 is installed in the guide hole 210 , and a guide rod 212 is installed at the bottom of the bag-supporting frame 22 , the guide rod 212 extends into the guide hole 210 and cooperates with the linear bearing 211 .

[0051] Specifically, the bottom of the base 21 is provided with a guide hole 210 that passes through the left and right sides, and the bottoms of the two bag-supporting frames 22 are respectively provided with two guide rods 212. The two guide rods 212 of each bag-supporting frame 22 extend into the guide hole 210 from the end of the guide hole 210 on its side, and cooperate with the linear bearing 211 therein to realize the guiding function when the bag-supporting frame 22 moves.

[0052] Furthermore, the provision of the linear bearing 211 can also limit the telescopic stroke of the guide rod 212 .

[0053] Two core shafts Ⅰ213 are centrally symmetrically arranged on the linkage disc 27, and the inner ends of the two connecting plates 28 are respectively hinged on the two core shafts Ⅰ213 through bearings, while a core shaft Ⅱ214 is arranged in the connecting hole 29, and the outer end of the connecting plate 28 is hinged on the core shaft Ⅱ214 through a bearing.

[0054] When the rotary cylinder 26 is started, its rotating assembly drives the linkage disc 27 to rotate synchronously, thereby driving the two bag-supporting frames 22 to move through the connecting plate 28. Through the cooperation between the guide rod 212 and the guide hole 210, the two bag-supporting frames 22 can realize linear movement towards or away from each other under the rotation of the rotary cylinder 26.

[0055] In this embodiment, in order to conveniently fix the bag-holding mechanism 2 on the turntable 11 , the rotary cylinder 26 is fixed to the bottom of the turntable 11 , and its rotating assembly extends from the turntable 11 and is fixed to the linkage disc 27 .

[0056] In order to facilitate the filling of fertilizer into the fertilizer bag 7 on the bag-supporting mechanism 2 , a feeding auger is installed inside the screw feeder 32 , and the feeding auger is connected to a feeding motor 33 installed at the outer end of the screw feeder 32 .

[0057] The discharge port of the hopper 31 is connected to the screw feeder 32 , and the fertilizer falls from the hopper 31 into the screw feeder 32 , and then the feeding auger is driven by the feeding motor 33 to rotate, so that the fertilizer is discharged from the discharge port of the screw feeder 32 into the fertilizer bag 7 .

[0058] In order to ensure that the fertilizer falls completely into the fertilizer bag 7, the discharge port of the screw feeder 32 is arranged downward.

[0059] In order to facilitate the grabbing of the bag mouth of the fertilizer bag 7, the grabbing claw 41 is a U-shaped mechanism with its opening facing downward, and a grabbing cylinder 42 is installed on its outer side. The piston rod of the grabbing cylinder 42 passes inward through the outer wall of the grabbing claw 41 and is installed with a clamping cap 43. The inner side of the inner wall of the grabbing claw 41 is provided with a clamping groove 44 that cooperates with the clamping cap 43.

[0060] The bag opening of the fertilizer bag 7 extends into the U-shaped opening, and then the piston rod of the grabbing cylinder 42 extends out to firmly clamp the bag opening of the fertilizer bag 7 between the pressing cap 43 and the pressing groove 44 .

[0061] The arrangement of the pressing groove 44 and the pressing cap 43 can increase the firmness of the grip with the fertilizer bag 7 .

[0062] In order to temporarily close the bag mouth after filling and avoid spilling of fertilizer during removal, the removal mechanism 4 also includes an air claw seat 45, the grabbing claw 41 is installed at the bottom of the air claw seat 45, and a linkage cylinder 46 is installed above the air claw seat 45. The linkage cylinder 46 can drive the two grabbing claws 41 to move toward or away from each other through a linkage plate 47 hinged on its piston rod.

[0063] Specifically, two slide grooves Ⅰ48 are installed at the bottom of the air claw seat 45, and a slide rail Ⅰ49 matching the slide groove Ⅰ48 is installed on the top of the grabbing claw 41 through a connecting block. The piston rod of the linkage cylinder 46 is set downward, and a cavity is set in the middle of the air claw seat 45. The linkage plate 47 includes two, the upper end of which is hinged to the piston rod of the linkage cylinder 46, and the lower end is hinged to the inner end of the two slide rails Ⅰ49 respectively.

[0064] The piston rod of the linkage cylinder 46 retracts, driving the two slide rails I49 to move toward each other, and then the two grab claws 41 move toward each other, so that the bag opening of the fertilizer bag 7 can be closed toward each other for temporary sealing, so as to avoid the fertilizer from spilling during the removal process.

[0065] When moving the filled fertilizer bag 7 from the bag supporting mechanism 2 to the conveyor belt 51, it is necessary to lift it up, so the removal mechanism 4 also includes a slider back plate 410, and the air claw seat 45 is vertically slidably fitted on the slider back plate 410. A lifting cylinder 411 is installed on the slider back plate 410, and the lifting cylinder 411 drives the air claw seat 45 and the linkage cylinder 46 to move up and down.

[0066] Specifically, the linkage cylinder 46 is fixed above the air claw seat 45, and the top of the linkage cylinder 46 is connected to the cylinder body of the lifting cylinder 411 through the connecting plate Ⅰ412. The piston rod of the lifting cylinder 411 is set downward, and the end of the piston rod is fixed on the slider back plate 410. The air claw seat 45 and the linkage cylinder 46 are driven to descend by the retraction of the piston rod of the lifting cylinder 411. Conversely, the air claw seat 45 and the linkage cylinder 46 are driven to rise by the extension of the piston rod of the lifting cylinder 411.

[0067] Preferably, a vertical slide groove II 413 is installed on the slider back plate 410, and a slide rail II 414 fixed on the air claw seat 45 is arranged below the connecting plate I 412. The slide rail II 414 and the slide groove II 413 are slidably matched, which can play a good guiding role in the lifting and lowering of the air claw seat 45.

[0068] In order to realize the reciprocating movement of the grabbing claw 41 on the turntable 11 and the conveyor belt 51, the removal mechanism 4 also includes a mounting plate 415, and the slider back plate 410 is slidably fitted on the mounting plate 415. A translation cylinder 416 is installed on the mounting plate 415, and the translation cylinder 416 can drive the slider back plate 410 to move.

[0069] Preferably, the translation cylinder 416 is a double-piston cylinder, both ends of which are fixed on the mounting plate 415 .

[0070] The slider back plate 410 is connected to the cylinder body of the translation cylinder 416 through the connecting plate II 417, and moves toward the piston rods on both sides of the translation cylinder 416, driving the slider back plate 410 and the grabbing claw 41 indirectly connected to the slider back plate 410 to move.

[0071] A slide rail III 418 having the same extension and retraction direction as the translation cylinder 416 is installed on the mounting plate 415, and a slide groove III 419 cooperating with the slide rail III 418 is installed on the slider back plate 410. The cooperation between the slide rail III 418 and the slide groove III 419 can play a good guiding role in the movement of the slider back plate 410.

[0072] Preferably, a proximity switch 420 is installed on the connecting plate II 417, and a pair of proximity switch contacts 421 are provided on the mounting plate 415. The setting of the proximity switch 420 can limit the moving stroke of the slider back plate 410. When it moves to the proximity switch contact 421 close to one side of the turntable 11, it indicates that the grabbing claw 41 reaches the position for grabbing the fertilizer bag 7. When the proximity switch 420 moves to the proximity switch contact 421 on the other side, it indicates that the fertilizer bag 7 moves to the conveyor belt 51. At this time, the fertilizer bag 7 can be released and transported out through the conveyor belt 51.

[0073] In order to realize the transmission of the conveyor belt 51 , the conveyor belt 51 is installed on a conveyor frame 52 , and a conveyor motor 53 is installed at the bottom of the conveyor frame 52 . The conveyor motor 53 is connected to one of the conveyor rollers of the conveyor belt 51 through a synchronous belt.

[0074] The removal mechanism 4 is fixed to one side of the conveying frame 52 through the vertical rod 422 , so as to facilitate the fertilizer bag 7 to be directly moved from the bag supporting mechanism 2 to the conveying belt 51 .

[0075] When filling waste materials, two of the four bag-supporting mechanisms 2 are at the filling station at the same time, one is at the removal station, and one is at the bagging station. The turntable 11 drives the four bag-supporting mechanisms 2 to rotate continuously to realize the switching of each station.

[0076] Specifically, the bag-holding mechanism 2 at the bag-filling station manually hangs the empty bag on the hook 24 of the bag-holding clamp 23, and then uses the rotary cylinder 26 to drive the two bag-holding frames 22 to open the bag mouth. The empty bag is then rotated to the first filling station, where half a bag of fertilizer is filled. The empty bag is then rotated to the second filling station, where the remaining half bag of fertilizer is filled. Finally, the empty bag is rotated to the removal station, and the removal mechanism 4 is used to move the filled fertilizer bag 7 to the conveyor belt 51 for transportation.

[0077] At the removal station, the grab claw 41 moves downward under the drive of the lifting cylinder 411, so that the bag opening of the fertilizer bag 7 extends into the U-shaped opening of the grab claw 41, and then the bag opening is clamped in the grab claw 41 by the grab cylinder 42. At this time, the two bag support frames 22 of the bag support mechanism 2 of this station move toward each other under the drive of the rotary cylinder 26, so that the bag opening is separated from the bag support clamp 23, and then the two grab claws 41 are driven by the linkage cylinder 46 to move toward each other to temporarily close the bag opening. At this time, the lifting cylinder 411 drives the grab claw 41 and the fertilizer bag 7 to move upward to separate them from the base 21. Finally, under the drive of the translation cylinder 416, the fertilizer bag 7 is clamped by the grab claw 41 and moved to the conveyor belt 51, and placed on the conveyor belt 51, and the fertilizer bag 7 is removed by the conveyor belt 51. At this time, the grab claw 41 is reset, which is convenient for the removal of the next fertilizer bag 7.

[0078] By means of the filling equipment disclosed in the present invention, the entire filling process can be automated, thereby improving the filling efficiency.

[0079] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
