Description

Technical Field

[0001] This utility model relates to the field of winnowing baskets, and specifically to a multifunctional winnowing basket. Background Technology

[0002] A dustpan is a cleaning tool used in daily life to hold garbage. It consists of a bowl and a broom. During cleaning, garbage such as paper scraps and hair are swept into the bowl. In order to clean the hair, fibers and other filaments that stick to or become tangled on the broom, a dustpan with comb teeth has appeared on the market. This dustpan uses the comb teeth to scrape the filaments off the broom, so that the broom can continue to sweep.

[0003] To address this issue, some dustpans on the market have implemented cleaning by making the comb teeth movable. However, these dustpans have a limited function, and light debris inside can easily be blown out by the wind, affecting floor cleanliness. Therefore, the function and structure of dustpans need further improvement. Utility Model Content

[0004] One objective of this invention is to provide a multifunctional winnowing basket that solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions: A multifunctional dustpan includes a main body and a vertical pole. The front of the main body has a collection opening for waste to enter. The side walls of the main body enclose a collection chamber where waste is collected. A comb-like mechanism is located above the collection opening or the collection chamber. The main body is equipped with a first driving mechanism and a second driving mechanism. The first driving mechanism allows the vertical pole to rotate relative to the main body, positioning the vertical pole and the main body in both a sweeping / collecting state and a storage state. The second driving mechanism is connected to the comb-like mechanism; the vertical movement and / or rotation of the vertical pole can drive the comb-like mechanism to extend and retract. By incorporating the first and second driving mechanisms into the dustpan, it simultaneously possesses a self-cleaning comb-like function and the ability to stand upright to prevent light waste from being blown out by the wind, thus making the dustpan more versatile.

[0006] Preferably, the first drive mechanism and the second drive mechanism are linked, with the operation of the first drive mechanism driving the operation of the second drive mechanism to simultaneously rotate the upright to the storage state and retract the comb teeth. The linked configuration of the two drive mechanisms allows for simultaneous control of the comb teeth's self-cleaning function and the dustpan's rotation state switching function, making operation more convenient. Simultaneously, the comb teeth's self-cleaning function can also be used independently to perform self-cleaning during sweeping. Regardless of whether the comb teeth are operated independently or in conjunction with the drive mechanism, the hair on the comb teeth will fall downwards into the collection chamber due to gravity.

[0007] Preferably, a functional compartment is provided on the rear side of the main body. The first driving mechanism includes a driving seat, which is located at the bottom of the upright and rotatably mounted in the functional compartment. Pushing the upright causes the driving seat to rotate relative to the main body. During the rotation of the driving seat, the upright remains located on the outer side of the top wall of the main body. The second driving mechanism includes a driving component and a linkage component. The driving component is mounted at the bottom of the upright and can move up and down relative to the driving seat. The two ends of the linkage component are respectively connected to the comb teeth and the driving component. The up and down movement and / or rotation of the upright causes the linkage component to pull the comb teeth backward and retract them. The first and second driving mechanisms have simple structures and can be linked by pushing and pulling the linkage component during the rotation of the driving seat.

[0008] Preferably, the linkage is made of flexible material or chain. During the up-and-down movement, the drive member moves the rear end of the linkage and deforms or moves the middle part to change the overall shape of the linkage, thereby pulling the comb teeth backward. The drive base is provided with a movable compartment with an open front side. The front end of the drive member or the rear end of the linkage can pass through the open side for connection. The side of the movable compartment is provided with an elongated groove extending vertically. The two sides of the drive member are inserted into the elongated groove to movably fix the drive member and the drive base.

[0009] Preferably, the front side of the linkage is set to be at the same height as the comb teeth, so that the pulling force of the linkage on the comb teeth and the moving direction of the comb teeth are on the same straight line. This avoids the pulling force of the linkage on the comb teeth being tilted relative to the moving direction of the comb teeth, which could cause the front end of the comb teeth to curl up or generate additional friction or jamming.

[0010] Preferably, guide arms are provided on both sides of the comb teeth, the linkage is installed in the middle of the comb teeth, and the two guide arms are symmetrically arranged on both sides of the linkage. The main body is provided with bosses that cooperate with the guide arms for guidance. The cooperation of the two sets of guide arms and bosses allows the comb teeth to maintain forward and backward movement even when the tension force on them is unbalanced. The length of the guide arm is greater than the distance between the mounting point of the linkage and the comb teeth or greater than the length between the position of the linkage entering the functional compartment and the comb teeth, so that the support point between the last end of the guide arm and the main body or the boss is located behind the tension force exerted by the linkage on the comb teeth. The arrangement of the guide arms and bosses restricts the movement of the comb teeth to the forward and backward direction without deviation, and the extended guide arms provide support to prevent the front end of the comb teeth from tilting upward.

[0011] Preferably, the main body is equipped with a first locking mechanism for positioning the drive seat in both the sweeping / collecting state and the storage state. In the sweeping / collecting state, the bottom surface of the main body forms a base and rests on the ground. In the storage state, the back of the main body and the surface of the drive seat together form a base to hold the dustpan upright on the ground. The first locking mechanism prevents rotation and wobbling between the upright and the main body when the dustpan is lifted. Furthermore, when sweeping, users habitually push the upright to tilt the main body so that the front end faces down and the rear end faces up. By locking the rotation between the upright and the main body, this user habit is satisfied, and the mechanism also prevents the main body from automatically rotating relative to the upright and falling when stored upright. Since the upright is on the outside of the main body in the storage state, and the upright is typically made of metal, is relatively tall and heavy, the combined support from the back of the main body and the drive seat makes the upright storage of the dustpan more stable.

[0012] Preferably, the functional compartment is provided with a support wall, and the support wall is provided with a hinge hole. The drive seat is inserted into the space between the support walls, and the hinge shafts on both sides of the drive seat are inserted into the hinge hole for connection. A torsion spring is provided between the hinge shaft and the hinge hole. The elastic force of the torsion spring causes the first locking mechanism to automatically rotate the upright and the drive seat to the storage state or to have a tendency to rotate to the storage state when the first locking mechanism is unlocked.

[0013] Preferably, the first locking mechanism includes a first locking groove and a first locking pin. The first locking groove is located on the side of the upright or the drive seat, and the first locking pin is movably mounted on the main body. When the first locking pin is inserted into the first locking groove, the upright and the drive seat cannot rotate relative to the main body. When the first locking pin moves away from the first locking groove, the upright and the drive seat can rotate relative to the main body and switch states.

[0014] Preferably, the first locking mechanism includes a first locking groove and a first locking pin. The first locking groove is disposed on the support wall, and the first locking pin is disposed on the side of the driving member. Both the first locking groove and the first locking pin are located at the rotational eccentric position of the driving seat. When the upright is in the high position, the first locking pin is located in the first locking groove, and the driving seat cannot rotate. When the upright is in the low position, the first locking pin disengages downward from the first locking groove, and the driving seat can start to rotate.

[0015] Preferably, the first locking mechanism further includes a second locking groove. The bottom of the first locking groove is provided with an arc-shaped groove corresponding to the rotation path of the first locking pin. The arc-shaped groove is provided with a slot corresponding to the size of the first locking pin. The slot forms the second locking groove. The first locking groove enters the second locking groove through the slot to restrict the rotation of the upright and the drive seat.

[0016] Preferably, the first locking mechanism further includes a second locking groove, which is located on the front side of the drive seat. A second locking pin is provided below the drive seat. The second locking pin is movably mounted on the main body. When the drive member is rotated to the storage position, the second locking pin can be inserted into the second locking groove. The second locking pin is provided with an elastic element, which keeps the second locking pin inserted into the second locking groove.

[0017] The advantages of this utility model are as follows: by setting a first drive mechanism and a second drive mechanism on the dustpan, the dustpan can simultaneously have the functions of comb tooth self-cleaning and upright placement to prevent light debris from being blown out by the wind, making the dustpan more versatile in its use; the linkage of the two drive mechanisms can simultaneously control the comb tooth self-cleaning function and the dustpan rotation usage state switching function, making operation more convenient. At the same time, the comb tooth self-cleaning function can also be operated independently to perform comb tooth self-cleaning during sweeping. Attached Figure Description

[0035] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0036] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0037] like Figure 1-17 A multifunctional dustpan includes a main body 1 and a vertical pole 2. The front of the main body 1 has a collection port 3 for garbage to enter. The side walls of the main body 1 enclose a collection chamber 4, where garbage is collected. A first driving mechanism is provided between the main body 1 and the vertical pole 2. This mechanism allows the vertical pole 2 to rotate relative to the main body 1, positioning the vertical pole 2 and the main body 1 in two states: a sweeping collection state where the vertical pole 2 is perpendicular to the collection port 3, and a storage state where the vertical pole 2 is parallel to the collection port 3. Figure 1 4 and 5, in the sweeping and collecting state, the bottom surface of the main body 1 forms a base, the bottom of the collection port 3 is in contact with the ground, and the broom sweeps the garbage on the ground from the collection port 3 into the main body 1; as Figure 6 In the storage state, the back of the main body 1 forms a base, and the collection port 3 is located at the top. The main body 1 and the upright 2 can be placed upright for storage. The side walls of the main body 1 prevent the garbage in the collection compartment 4 from falling, so that the main body 1 forms a garbage can with the collection port 3 at the top. When the dustpan is in the sweeping collection state, the top of the main body 1 has a compartment 5, and the compartment 5 has comb teeth 6. The broom can contact the comb teeth 6 to clean the hair and other garbage on the broom. A second drive mechanism is provided between the comb teeth 6 and the upright 2. The upright 2 moves up and down relative to the main body 1. The second drive mechanism drives the comb teeth 6 to move and extend, so that the comb teeth 6 can clean the hair attached to the broom. The hair cleaned by the comb teeth 6 falls into the main body 1 for collection due to gravity.

[0038] Preferably, the first drive mechanism and the second drive mechanism can be controlled to operate independently, or they can be controlled to operate simultaneously by the activity state of the upright 2. Example 1

[0039] like Figure 1-11 In this embodiment, the back of the main body 1 is provided with a functional compartment 7, which is separated from the collection compartment 4. The top of the functional compartment 7 is connected to the interlayer 5. The first drive mechanism and the second drive mechanism are both installed in the functional compartment 7 or in the area where the functional compartment 7 and the interlayer 5 are located. The first drive mechanism includes a drive seat 8, which is located at the lower end of the upright 2. The drive seat 8 is rotatably installed on the upper part of the functional compartment 7. When the upright 2 rotates, the drive seat 8 rotates and changes its angle within the functional compartment 7. The upright 2 is always located on the outside of the top wall of the main body 1. The functional compartment 7 is provided with a support wall 9, which has hinge holes 10. The drive seat 8 is inserted entirely into the space between the support walls 9. The hinge shafts 11 on both sides of the drive seat 8 are inserted into the hinge holes 10 for installation. The support walls 9 provide support for both sides of the drive seat 8 to prevent the drive seat 8 from shaking during rotation.

[0040] Preferably, a torsion spring 12 is provided on the hinge shaft 11. The elastic force of the torsion spring 12 causes the drive seat 8 to remain in the retracted state or tend to rotate towards the retracted state. A first groove 13 is provided around the hinge hole 10. An extension groove 14 is provided below the first groove 13. At least part of the torsion spring 12 is accommodated in the first groove 13. One elastic arm of the torsion spring 12 is accommodated in the extension groove 14, and the other elastic arm is outside the first groove 13 and supported by the main body 1 or the hinge seat.

[0041] The torsion spring 12 allows the upright 2 and drive seat 8 to rotate into the storage state. However, the elastic force of the torsion spring 12 makes it difficult for the upright 2 and drive seat 8 to remain in the storage state. The main body 1 is also provided with a first locking mechanism. The first locking mechanism overcomes the elastic force of the torsion spring 12 and keeps the upright 2 and drive seat 8 in the storage state. The first locking mechanism can lock and unlock by its own movement, so that the upright 2 and drive seat 8 can rotate and be positioned.

[0042] Specifically, the first locking mechanism includes a first locking groove 15 and a first locking pin 16. The first locking groove 15 is located on the side of the upright 2 or the drive seat 8. The first locking pin 16 is movably mounted on the main body 1. When the first locking pin 16 is inserted into the first locking groove 15, the upright 2 and the drive seat 8 cannot rotate relative to the main body 1. When the first locking pin 16 moves away from the first locking groove 15, the upright 2 and the drive seat 8 can rotate relative to the main body 1, switching states. The movable structure of the first locking pin 16 can adopt a laterally moving push rod structure or a press-and-rotate seesaw structure. This embodiment uses a laterally moving push rod structure for illustration. Specifically, as shown in the example... Figure 8The first locking pin 16 is movably installed in the functional compartment 7. The portion of the first locking pin 16 outside the first locking groove 15 extends towards the top of the functional compartment 7 and protrudes from the top surface of the main body 1. Locking and unlocking are achieved by manually pushing the first locking pin 16. For ease of operation, the movement of the first locking pin 16 can also be controlled by pressing, suitable for locking or unlocking by foot pedal, such as... Figure 9 and 10 The first locking mechanism also includes a control switch 17, which is installed on the top surface of the main body 1 by pressing up and down. The lower end of the control switch 17 enters the functional compartment 7 and is provided with a first push surface 18. The first locking pin 16 is provided with a second push surface 19. Both the first push surface 18 and the second push surface 19 are set as inclined surfaces. When the control switch 17 is pressed down, the first push surface 18 and the second push surface 19 cooperate to make the first locking pin 16 move laterally and disengage from the first locking groove 15.

[0043] Preferably, the first locking pin 16 is provided with an elastic element 20. Regardless of whether the structure is moved by direct push and pull or indirectly controlled by the unlocking switch, the elastic element 20 can keep the first locking pin 16 in the position of the first locking groove 15 or maintain the tendency to move towards the first locking groove 15. When the first locking pin 16 automatically moves and inserts into the first locking groove 15, the unlocking switch can automatically fall to the position of pre-fitting with the first locking pin 16 under gravity.

[0044] To position the upright 2 and drive seat 8 in the retracted state, the front side of the drive seat 8 is also provided with a second locking groove 21. When the upright 2 and drive seat 8 are in the retracted state, the second locking groove 21 rotates to the position corresponding to the first locking pin 16. Under the action of the elastic member 20, the first locking pin 16 automatically moves to the position that cooperates with the second locking groove 21, preventing the upright 2 and drive seat 8 from rotating.

[0045] Preferably, the hinge shaft 11 of the drive seat 8 is located above the front side of the hinge shaft 11.

[0046] Preferred, such as Figure 2 and 3 The top and back of the functional compartment 7 are open to allow the uprights 2 and drive seat 8 to rotate and make room. When the uprights 2 and the main body 1 are in the sweeping and collecting state, the back of the drive seat 8 blocks the opening and forms part of the back of the main body 1. When the uprights 2 and the drive seat 8 are rotated to the storage state, the bottom of the drive seat 8 is located on the back of the main body 1 and is flush with the back of the main body 1. The bottom of the drive seat 8 and the back of the main body 1 together support the dustpan on the ground to achieve upright placement of the dustpan. In this embodiment, when the dustpan is in the storage state, the drive seat 8 protrudes from the top surface of the main body 1 to expand the support range between the dustpan and the ground and improve the stability of the dustpan when placed upright.

[0047] like Figure 4-7 The second drive mechanism includes a drive component 22 and a linkage component 23. The drive component 22 is fixedly installed at the bottom of the upright 2. The two ends of the linkage component 23 are respectively connected to the drive component 22 and the comb teeth 6. Pressing down on the upright 2 causes the drive component 22 to move down synchronously. The linkage component 23 is forced to move down and pulls the comb teeth 6 to move backward and retract into the interlayer 5.

[0048] Preferably, the linkage 23 is made of a flexible material or a chain. During the up-and-down movement of the drive member 22, one end of the linkage 23 moves, and the middle part deforms or moves to change the overall shape of the linkage 23, thereby pulling the comb teeth 6 backward. In this embodiment, the linkage 23 is set as a flexible pull belt, and both ends of the linkage 23 are fixedly connected to the drive member 22 and the comb teeth 6, respectively.

[0049] Since the driving component 22 moves vertically up and down, and the comb teeth 6 move horizontally back and forth, while the linkage component 23 has an inclined shape with the rear side lower than the front side during linkage, the pulling force of the linkage component 23 on the comb teeth 6 is inclined and forms an angle with the moving direction of the comb teeth 6. According to force analysis, the inclined pulling force will cause the comb teeth 6 to have a tendency to sink at the rear end and tilt upward at the front end. Although the upward tilt of the comb teeth 6 is limited by the upper and lower limit of the main body 1, the comb teeth 6 will still rub against the main body 1 when moving, converting part of the inclined pulling force into frictional force, affecting the smoothness of the movement of the comb teeth 6. To ensure that the pulling force of the comb teeth 6 is more stable, such as Figure 7 In this embodiment, the front side of the linkage 23 is set to be at the same height as the comb teeth 6, so that the pulling force of the linkage 23 on the comb teeth 6 and the moving direction of the comb teeth 6 are on the same straight line, making the forward and backward movement of the comb teeth 6 smoother.

[0050] In this embodiment, guide arms 24 are provided on both sides of the comb teeth 6, and a linkage 23 is installed in the middle of the comb teeth 6. The two guide arms 24 are symmetrically arranged on both sides of the linkage 23, and the distance between the two guide arms 24 and the linkage 23 is the same, so that the tension on the comb teeth 6 is more balanced. The main body 1 or the interlayer 5 is provided with a boss 25 that cooperates with the guide arms 24 for guidance. The cooperation between the two guide arms 24 and the boss 25 allows the comb teeth 6 to maintain forward and backward movement even when the tension on them is unbalanced. An elastic element 20 is provided between the guide arms 24 and the comb teeth 6 so that the comb teeth 6 can automatically move forward and extend. Preferably, as Figure 11 The length of the guide arm 24 is greater than the distance between the mounting point of the linkage 23 and the comb tooth 6, and even greater than the length between the position of the linkage 23 entering the functional compartment 7 and the comb tooth 6. This makes the support point between the rear end of the guide arm 24 and the main body 1 or the boss 25 located behind the pulling force of the linkage 23 on the comb tooth 6. Even if the pulling force of the linkage 23 on the comb tooth 6 is vertically inclined, the support at the rear end of the guide arm 24 can prevent the front end of the comb tooth 6 from tilting upward, thereby making the forward and backward movement of the comb tooth 6 more stable.

[0051] Preferably, the drive base 8 has a movable compartment 26, and the drive component 22 is movably installed in the movable compartment 26. Specifically, the front side of the movable compartment 26 is open, and the front end of the drive component 22 or the rear end of the linkage component 23 can pass through the open and be connected. The top of the rear side of the drive base 8 has a hollow tube sleeve 27. The drive component 22 has a rod opening at the position corresponding to the tube sleeve 27. The upright 2 passes downward through the tube sleeve 27 and is inserted into the rod opening to be fixedly connected to the drive component 22. The tube sleeve 27 surrounds the outside of the upright 2, and the surface of the tube sleeve 27 and the upright 2 or the rod opening cooperates to support and prevent the upright 2 from shaking. The side of the movable compartment 26 has an elongated groove 28 extending vertically. The two sides of the drive component 22 are inserted into the elongated groove 28 to fix the drive component 22 and the drive base 8 movably. When in use, pressing down on the upright 2 causes the drive component 22 to move downward relative to the drive base 8 and the main body 1. The rear side of the linkage component 23 is pulled downward, causing the front side to follow the force and move backward, thereby pulling the comb teeth 6 backward to achieve extension and retraction.

[0052] Preferably, an elastic element 20 is provided between the lower part of the drive member 22 and the drive base 8. The elastic force of the elastic element 20 pushes the drive member 22 and the upright 2 to move upward and reset. Due to the characteristics of the linkage 23 itself when the drive member 22 and the upright 2 reset upward, the rear side of the linkage 23 can move upward and follow. The linkage 23 cannot generate a thrust to push the comb teeth 6 to extend forward. The middle part of the linkage 23 is bent in the functional compartment 7 or the interlayer 5. The elastic element 20 on the comb teeth 6 automatically pushes the comb teeth 6 to move forward and extend, and pulls the linkage 23 to reset forward.

[0053] In the above embodiments, the rotation between the upright 2 and the main body 1 is locked and unlocked by the first locking mechanism. The upright 2 and the comb teeth 6 are not locked by the first locking mechanism, nor is a separate locking mechanism provided for locking them. Figure 6 When the dustpan is in the sweeping and collecting state, the comb teeth 6 can always extend and retract. During the rotation of the upright 2, the top of the drive seat 8 rotates to the position of contacting the linkage 23. The drive seat 8 continues to rotate, pulling the middle of the linkage 23 downward until the upright 2 and the drive seat 8 rotate to the retracted state. At this time, the comb teeth 6 are pulled back by the linkage 23. During this process, the linkage 23 is always in a taut state. When the upright 2 and the drive seat 8 rotate to reset, the top of the drive seat 8 moves upward and away from the linkage 23. The linkage 23 is no longer obstructed, and the elastic element 20 on the comb teeth 6 drives the comb teeth 6 to move forward and extend. The linkage 23 also resets upward and forward. Example 2

[0054] The similarities between Example 2 and Example 1 will not be repeated here. Only the differences will be described, which are: the specific structure of the first locking mechanism.

[0055] like Figure 12-17In this embodiment, the first locking mechanism achieves locking and unlocking through the movement of the upright 2 or the driving member 22, without the need for a separate switch for control. Specifically, the first locking mechanism includes a first locking groove 15 and a first locking pin 16. The first locking groove 15 is located on the support wall 9, and the first locking pin 16 is located on the side of the driving member 22. Both the first locking groove 15 and the first locking pin 16 are located at the rotational eccentric position of the driving seat 8. When the upright 2 is in the high position, the first locking pin 16 is located in the first locking groove 15 and the driving seat 8 cannot rotate. When the upright 2 is in the low position, the first locking pin 16 disengages downward from the first locking groove 15, and the driving seat 8 begins to rotate.

[0056] Preferred, such as Figure 13 and 14 The first locking groove 15 is located at the same height as the long groove 28. The part of the driving member 22 inserted into the long groove 28 extends outward and inserts into the first locking groove 15 to form the first locking pin 16. When the upright 2 is pressed, the driving member 22 moves downward, and the first locking pin 16 moves downward along the long groove 28 and the first locking groove 15 at the same time until the first locking pin 16 disengages from the bottom of the first locking groove 15. The upright 2, the driving seat 8 and the driving member 22 rotate around the hinge shaft 11 on the driving seat 8 at the same time.

[0057] In this embodiment, the structure of the second locking groove 21 can be configured in two ways, the first being: as follows Figure 13 and 14 The bottom of the first locking groove 15 is provided with an arc-shaped groove 29 corresponding to the rotation path of the first locking pin 16. The arc-shaped groove 29 is provided with a slot 30 corresponding to the size of the first locking pin 16. A second locking groove 21 is formed above the slot 30. When the upright 2 drives the driving member 22 and the first locking pin 16 to move downward to the bottom of the first locking groove 15, the arc-shaped groove 29 makes way for the first locking pin 16. The upright 2, the driving seat 8 and the driving member 22 can rotate. The first locking pin 16 rotates along the arc-shaped groove 29. The upright 2 rotates to the storage position. The first locking groove 15 passes through the slot 30 and enters the second locking groove 21 and prevents the upright 2 and the driving seat 8 from rotating. When the slot 30 is released, the first locking pin 16 can be disengaged from the slot 30 and enter the arc-shaped groove 29 to rotate by simply using external force to pry the upright 2 and the main body 1. The first locking pin 16 is located at the bottom of the first locking groove 15. The elastic member 20 pushes the first locking pin 16 to move upward along the first locking groove 15.

The relief groove 33 can provide relief for the protrusion 32 or the second locking pin 31, so as to prevent the up and down movement of the drive member 22 from being affected by the second locking pin 31 below. The second locking pin 31 is provided with an elastic member 20 below it. The elastic member 20 keeps the second locking pin 31 inserted into the second locking groove 21. When the state changes, the drive member 22 moves downward and pushes the second locking pin 31 to overcome the elastic force of the elastic member 20 and move downward to the position below the protrusion 32 and out of the relief groove 33, so that the upright 2, the drive seat 8 and the drive member 22 are in a position where they are not ... It can be rotated until the second locking pin 31 disengages from the abutment of the drive member 22 and automatically inserts into the second locking groove 21 for positioning. It can be understood that the cooperation between the second locking pin 31 and the relief groove 33 prevents the drive seat from rotating from the sweeping and collecting state to the storage state, which is equivalent to the cooperation between the first locking groove 15 and the first locking pin 16 mentioned above. Based on the second locking pin 31 and the relief groove 33 of this structure, the first locking groove 15 and the first locking pin 16 on the support wall 9 and the drive member 22 are removed, so that the second locking pin 31 cooperates with the relief groove 33 and the second locking groove 21 for limiting, so that the second locking pin plays the positioning role of the first locking pin and the relief groove 33 plays the role of the first locking groove.

[0060] Based on the setting of the second locking pin 31, the rear side of the linkage 23 can also be installed by connecting to the second locking pin 31. Specifically, the elastic element 20 keeps the second locking pin 31 in a high position, the second locking pin 31 is inserted into the clearance groove 33, the comb teeth 6 extend forward, the rear side of the linkage 23 is in a high position, the upright 2 is pressed, the driving element 22 moves downward and pushes the second locking pin 31 to overcome the elastic force of the elastic element 20 and move downward. The rear side of the linkage 23 follows the second locking pin 31 to move downward, the front side moves backward and pulls the comb teeth 6 to retract, the second locking groove 21 is disengaged from the clearance groove 33, the first locking pin 16 is located at the bottom of the first locking pin 16, the upright 2, the driving seat 8 and the driving element 22 can rotate until the second locking pin 31 is inserted into the second locking groove 21, and the winnowing basket completes the retraction of the comb teeth 6 and rotates to the storage position.
