Description

Technical Field

[0001] The present invention relates to the technical field of garbage sorting, and in particular to a fork-type garbage sorting device. Background Art

[0002] As human society develops, large quantities of various types of waste are inevitably generated. The effective treatment and utilization of this waste is an important component of sustainable development, and the key to recycling these resources lies in waste classification. Traditional manual sorting methods suffer from inefficiency, misclassification, harsh working environments, and limitations on large-scale recycling. While deploying automated machinery on waste sorting production lines can meet the requirements of high-precision, high-speed, and high-efficiency sorting, further efficient utilization requires careful selection. For example, fine-grained sorting of plastic waste improves the quality of recycling and further increases the value of waste recycling.

DETAILED DESCRIPTION

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1As shown, a fork-type garbage sorting device includes a support mechanism 1, a roller conveyor belt 5, a horizontal drive mechanism 2, a vertical drive mechanism 3 and a fork-picking mechanism 4. The horizontal drive mechanism 2 is installed on the upper end of the support mechanism 1, the vertical drive mechanism 3 is installed on the horizontal drive mechanism 2, and the fork-picking mechanism 4 is installed on the vertical drive mechanism 3. In this embodiment, the roller conveyor belt 5 is laid under the fork-picking mechanism 4 to facilitate the fork-picking mechanism 4 to operate on the garbage on the roller conveyor belt 5. Sorting troughs 6 are installed on both sides of the roller conveyor belt. The sorting trough 6 can accommodate the garbage carried by the fork-picking mechanism 4. A drop plate 11 is further installed between the roller conveyor and the fork-picking mechanism 4. The drop plate is installed above the roller conveyor. The drop plate 11 is provided with a drop groove 111 in the same direction as the horizontal movement of the fork-picking mechanism. When the garbage is forked, the lower end of the fork-picking shell passes through the drop groove; when the fork-picking mechanism 4 carries the garbage in the drop groove and moves to the top of the sorting trough 6, the fork-picking mechanism 4 moves upward through the drop groove 111, and the drop plate 11 can drop the garbage into the sorting trough 6.

[0043] like Figure 3 As shown, the horizontal drive mechanism 2 includes a synchronous belt driven slide 22, a motor 23 and a slider 24. The horizontal drive mechanism mounting seat 21 is installed on the upper end of the support mechanism 1. One end of the synchronous belt driven slide 22 is fixed to the support mechanism 1 through the horizontal drive mechanism mounting seat 21, and is located above the drop plate 11 and parallel to the drop plate 11. The fork mechanism can move between the sorting trough 6 and the roller conveyor belt along the synchronous belt driven slide 22. The motor 23 is installed at the other end of the synchronous belt driven slide 22, and the slider 24 is installed on the synchronous belt of the synchronous belt driven slide 22. The motor 23 is electrically connected to the slider 24 to control the movement of the slider 24.

[0044] like Figure 2 and Figure 4 As shown, the vertical drive mechanism 3 includes a telescopic part and a mounting part 33. The telescopic part includes a double-acting cylinder 31 and a connecting seat 32. The mounting part 33 is mounted on the slider 24, the double-acting cylinder 31 is mounted on the mounting part 33, and the connecting seat 32 is mounted on the telescopic rod of the double-acting cylinder 31. In this embodiment, there are two double-acting cylinders 31, which are mounted on both sides of the synchronous belt-driven slide 22. The two double-acting cylinders 31 run synchronously, and the two connecting seats 32 are respectively mounted on the telescopic rods of the double-acting cylinder 31.

[0045] like Figure 4-5As shown, the forking mechanism 4 includes a forking body 41 and a control component 42. The control component 42 is mounted on the mounting portion 33 and connected to the forking body 41. The upper end of the forking body 41 is fixed to the connecting seat 32 through the forking body fixing rod 4115. The control component 42 includes a switch rod 421, a switch rod mounting seat 422 and a switch rod rotating shaft 423. The upper end of the switch rod mounting seat 422 is connected to the mounting portion 33. The switch rod mounting seat 422 includes two symmetrically arranged mounting plates. A switch rod groove is formed between the mounting plates. Both ends of the switch rod rotating shaft 423 are respectively connected to the mounting plates and are horizontally mounted in the switch rod groove. The switch rod 421 is vertically mounted in the switch rod groove. The middle part of the switch rod 421 is connected to the switch rod rotating shaft 423 is hinged, and the lower end of the switch rod 421 is in contact with the side wall of the fork body 41. The switch rod 421, the switch slot 4114 and the inverted slot 4113 are in the same straight line. When the fork body 41 moves vertically, the switch rod 421 can touch the contact switch 4151 to achieve the function of controlling the opening and closing of the inverted insertion component 412. The two switch rod limit shafts 424 are symmetrically installed on the upper and lower sides of the switch rod rotation shaft 423. The switch rod 421 is installed on the switch rod rotation shaft 423, so that the switch rod 421 can rotate with the switch rod rotation shaft 423 as the axis, cooperating with the up and down movement of the fork body 41 to better control the inverted insertion component 412. The switch rod limit shaft 423 can limit the rotation angle of the switch rod 421.

[0046] like Figure 6-7 As shown, the fork body 41 includes a fork shell 411, an inverted insertion component 412, a connecting rod component 413, a tooth column component 414 and a switch component 415. The inverted insertion component 412, the connecting rod component 413, the tooth column component 414 and the switch component 415 are installed in the fork shell 411 and connected in sequence. The upper end of the fork shell 411 is connected to the connecting seat 32 through the fork body fixing rod 4115. The side wall of the fork shell 411 is provided with an inverted slot 4113 and a switch slot 4114. The switch slot 4114 is used to install the contact switch 4151 and cooperates with the switch rod 421 to achieve a control effect.

[0047] In this embodiment, the fork-picking shell 411 includes a wrapping portion 4111 and a puncture portion 4112. The wrapping portion 4111 and the puncture portion 4112 are integrally formed. The puncture portion 4112 is in the shape of an inverted cone, which can reduce the resistance generated by puncturing garbage. The upper end of the wrapping portion 4111 is connected to the connecting seat 32 through the fork-picking body fixing rod 4115. There are two inverted slots 4113, which are opened on two opposite surfaces of the wrapping portion 4111 for installing the inverted insertion body 4122 and a switch for facilitating the inverted insertion of the body 4122.

[0048] like Figure 8As shown, the inverted plug assembly 412 includes an inverted plug mounting seat 4121, an inverted plug body 4122 and an inverted plug rotating member 4123. The inverted plug body 4122 is installed in the inverted slot 4113. The inverted plug body 4122 includes a fixing portion and a hook lock portion. The fixing portion and the hook lock portion are integrally formed. The hook lock portion is triangular. The lower end of the fixing portion is installed in the fork-taking shell through an inverted fixing connecting rod 4124. The upper end of the fixing portion is connected to one end of the inverted plug rotating member 4123 through an inverted rotating shaft 4125. The other end of the inverted plug-in rotating member 4123 is connected to the inverted plug-in mounting seat 4121. The inverted plug-in rotating member 4123 is T-shaped. The inverted plug-in rotating member 4123 is driven by the inverted plug-in mounting seat 4121 and rotates around the connection between the inverted plug-in rotating member 4123 and the inverted plug-in mounting seat 4121, thereby driving the inverted plug-in body 4122 to rotate with the inverted plug-in fixing link 4124 as the axis. The fixed part can thus extend or return to the inverted slot 4113 to realize the function of locking and releasing the garbage hook.

[0049] like Figure 8 As shown, the connecting rod assembly 413 includes a free connecting rod extension 4131, a fixed guide rail 4132 and a return spring 4133. The upper end of the free connecting rod extension 4132 is connected to the tooth column assembly 414, the lower end of the free connecting rod extension 4131 is connected to the inverted assembly 412, one end of the fixed guide rail 4132 is connected to the fixed guide rail mounting seat 4134, the other end of the fixed guide rail 4132 passes through the inverted plug mounting seat 4121, the fixed guide rail mounting seat 4134 is installed on the fork housing 411, the return spring 4133 is sleeved on the fixed guide rail 4132, one end of the return spring 4133 is connected to the inverted assembly 412, and the other end of the return spring 4133 is connected to the fixed guide rail mounting seat 4134.

[0050] In this embodiment, the connecting rod assembly 413 further includes a contact ball 4135 , which is mounted on the upper end of the free connecting rod extension 4131 and contacts the gear column assembly 414 . The arrangement of the contact ball 4135 can reduce the resistance of the rotating gear column 4143 during rotation.

[0051] The free connecting rod extension 4131 includes a transition portion and an extension portion. The transition portion and the extension portion are integrally formed. A spherical groove for installing the contact ball 4135 is provided at the upper end of the transition portion. A guide groove is provided between the extension portions. The fixed guide rail mounting seat 4134 is installed in the guide groove. The lower end of the extension portion is connected to the inverted plug-in mounting seat 4121. When the free connecting rod extension 4131 moves up and down, the fixed guide rail mounting seat 4134 will not interfere in the guide groove, making the connecting rod assembly more compact and saving space.

[0052] In this embodiment, the contact ball 4135 moves downward after being pressurized by the tooth column assembly 414, and the lower end of the extension portion presses the inverted plug-in mounting seat 4121, thereby driving the inverted plug-in body 4122 to rotate outward and extend out of the inverted slot 4113, thereby achieving the function of hooking and locking the garbage. After the pressure of the contact ball 4135 is released, the return spring 4133 will generate an upward contraction force due to being stretched, driving the inverted plug-in mounting seat 4121 to move upward, thereby prompting the inverted plug-in body 4122 to close, and releasing the hook lock state for the garbage.

[0053] like Figure 9-11 As shown, the gear column assembly 414 includes a linear gear column 4141, a fixed gear ring 4142 and a rotating gear column 4143. The fixed gear ring 4142 is installed on the fork housing 411 by a fixing screw 41424. The upper end of the linear gear column 4141 is connected to the switch assembly 415. The lower end of the linear gear column 4141 passes through the fixed gear ring 4142 and abuts against the upper end of the rotating gear column 4143. The rotating gear column 4143 is sleeved on the fixed gear ring 4142, and the lower end of the rotating gear column 4143 abuts against the contact ball 4135.

[0054] In this embodiment, the fixed tooth ring 4142 includes a plurality of first fixed portions 41421 and a plurality of first angled teeth 41422. The first fixed portions 41421 and the first angled teeth 41422 are connected end to end in a staggered manner. A first guide groove 41423 is formed between two adjacent first angled teeth 41422. The rotating tooth column 4143 includes a second fixed portion 41431, a second angled tooth 41432 and a contact portion 41434. The contact portion 41 434 is integrally formed with the second fixed portion 41431. The second angled teeth 41432 are circumferentially distributed on the side wall of the contact portion 41434. A second guide groove 41433 is formed between two adjacent second angled teeth 41432. An equilateral tooth ring 41411 is provided at the lower end of the linear tooth column 4141. The outer wall of the equilateral tooth ring 41411 is in contact with the inner wall of the fixed tooth ring 4142. The equilateral tooth ring 41411 corresponds to the second angled teeth 41432.

[0055] When the inverted body 4122 is closed, the second angled tooth 41432 is inserted into the first guide groove 41423 , and the first angled tooth 41422 is inserted into the second guide groove 41433 .

[0056] When the inverted body 4122 needs to be opened, the fork body 41 moves downward to the lower end of the switch rod 421, and the lower end of the switch rod 421 presses the contact switch 4151, causing the linear tooth column 4141 to be pressed by the switch assembly 415, and the linear tooth column 4141 moves downward. The equilateral tooth ring 41411 engages with the second angled tooth 41432 and pushes the second angled tooth 41432 to move downward out of the first guide groove 41423. Then the fork body 41 continues to move downward, and the switch rod 421 releases the pressure on the contact switch 4151. The return spring 4133 contracts, driving the rotating tooth column 4143 to move upward, and the second angled tooth 41432 rotates and moves upward along the tooth edge of the first angled tooth 41422 and engages with the first angled tooth 41422, and then remains stationary. At this time, the return spring 4133 stops contracting due to resistance, thereby causing the inverted assembly 412 to remain in the open state unchanged.

[0057] When the fork body 41 moves up to the upper end of the switch rod 421, the upper end of the switch rod 421 presses the contact switch 4151, causing the linear tooth column 4141 to move downward under pressure, and the equilateral tooth ring 41411 contacts the second fixing portion 41431 and pushes the second fixing portion 41431, releasing the engagement state of the first angled tooth 41422 and the second angled tooth 41432, and the fork body 41 continues to move up, the switch rod 421 releases the pressure on the contact switch 4151, the return spring 4133 contracts, driving the rotating tooth column 4143 to move upward, and the second angled tooth 41432 rotates and moves upward along the tooth edge of the first angled tooth 41422, and is inserted into the first guide groove 41423, and the inverted assembly 412 is immediately closed.

[0058] like Figure 12 As shown, the switch assembly 415 includes a contact switch 4151, a hollow angled piece 4152, a ball group 4153 and a compression pleated sleeve 4154. The contact switch 4151 is installed in the switch slot 4114, and the compression pleated sleeve 4154 is installed at the upper end of the linear tooth column 4141. One end of the hollow angled piece 4152 is connected to the linear tooth column 4141 through the compression pleated sleeve 4154. The hollow angled piece 4152 is connected to the interior of the compression pleated sleeve 4154. One end of the contact switch 4151 is inserted into the hollow angled piece 4152. The ball group 4153 is installed inside the hollow angled piece 4152 and the compression sleeve 4154. One end of the ball group 4153 is against the tooth column assembly 414, and the other end is against the contact switch 4151.

[0059] In this embodiment, the compression pleated sleeve 4154 is retractable, and the switch rod 421 presses the contact switch 4151. The contact switch 4151 is forced to push the ball group 4153, and the ball group 4153 then pushes the linear gear column 4141 downward, driving the inverted assembly 412 to open. When the switch rod 421 releases the pressure on the contact switch 4151, the ball group 4153 and the contact switch 4151 are driven by the gear column assembly 414 and the connecting rod assembly 413 to return to their original state.

[0060] When the present invention is used, when the roller conveyor belt transports the garbage to the designated location, the fork mechanism passes downward through the drop trough, hooks and locks the garbage and moves to the designated sorting trough under the drive of the horizontal drive mechanism. When the fork mechanism moves upward and retracts, the garbage is dropped into the sorting trough under the blocking action of the drop plate to achieve the garbage sorting effect.

[0061] like Figure 13-18 As shown, the working process of the fork mechanism is simplified to the AF state;

[0062] like Figure 13 As shown, state A: the fork body moves to the top of the designated garbage through the horizontal drive mechanism, the puncture part slightly passes through the drop groove, and when the fork body is controlled by the vertical drive mechanism, it can move downward at high speed;

[0063] like Figure 14 As shown, in state B: the fork body moves downward, and the puncture part passes through the designated garbage. During this process, the switch slot at the upper end of the fork shell touches the switch rod, and the switch rod presses the contact switch, causing the inverted body to extend out of the inverted slot;

[0064] like Figure 15 As shown, state C: the fork body continues to move downward, the switch rod is rotated by force, and the pressure on the contact switch is released. At this time, the inverted assembly remains in the open state, and the hook locks the garbage;

[0065] like Figure 16 As shown, state D: the fork body is moved to the designated sorting trough by the horizontal drive mechanism, the fork body moves upward, the switch rod presses the contact switch, and the inverted body remains in the open state under the drive of the contact switch;

[0066] like Figure 17 As shown, in state E: the fork body continues to move upward, the switch rod rotates, releasing the pressure on the contact switch, driving the inverted assembly to close and maintain the closed state.
