Abstract

The present invention relates to a pulverizing device comprising a main body, a cover plate, and a support assembly. The main body includes a motor, a control panel, a power supply compartment, and a power interface disposed within the compartment. The motor's pivot axis is X3, and the power interface is disposed parallel to X3. The present invention optimizes the layout of the control panel and the power supply compartment, thereby shortening the main body along the motor axis while maintaining the same pulverizing capacity, making the entire device more compact and lightweight. Two modes, namely, a pre-set working state and a storage state, are configured for flexible switching around a rotating body during use. A removable battery pack is disposed in the power supply compartment parallel to X3. When the pulverizing device is in the storage state, the battery pack cannot be stored within the housing, thereby reducing the overall weight and size of the device.

Description

Technical Field

[0001] The invention relates to a comminution device. Background Art

[0002] When the whole machine is in working state, the whole machine is tall, large in size, and not light, which makes it inconvenient for users to carry and use. In order to solve the problem of large size during transportation and storage, the existing technology adopts technical means such as folding storage and DC power supply. Since the main body adopts a conventional size body design, the volume of the box for storing the main body is also large, which can accommodate the battery pack when stored, making the overall weight heavy when stored.

[0003] The prior art provides a crushing device that partially solves the defect of large space size in the storage state. However, due to the large space size of its main body and the fact that it can still be folded and stored in the box after the battery pack is installed, the entire device is heavy and has a large body size. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a crushing device with light overall weight and reduced body volume.

[0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a crushing device, comprising at least a main body, a cover plate and a supporting assembly, wherein the main body comprises a motor, a control panel, a power supply compartment and a power supply interface arranged in the power supply compartment, the pivot axis of the motor is X3, and the power supply interface is arranged parallel to X3.

[0006] Preferably, the main body includes a blanking channel, and the control board is arranged above X3 and is located between the blanking channel and the power supply compartment in the axial direction of X3.

[0007] Preferably, the main body includes an air inlet, which is arranged above X3 and between the blanking channel and the power supply compartment in the axial direction of X3.

[0008] Preferably, the main body includes a rotating body, the supporting assembly includes a box body, and the crushing device has a working state and a storage state. When the crushing device is in the working state, the rotating body is located above the box body, and there is no overlap between the rotating body and the box body in the height direction. The rotating body is located on the upper side of the cover plate, and the rotating body partially overlaps with the cover plate in the height direction.

[0009] Preferably, the battery pack is detachably mounted in the power supply compartment in a direction parallel to X3, and when the crushing device is in the storage state, the battery pack must not be stored in the box.

[0010] Preferably, the length dimension of the main body parallel to the cover plate in the working state is L9, and the length dimension of the main body parallel to the cover plate in the storage state is L8, wherein L8>L9.

[0011] Preferably, the supporting assembly includes a rotating part, the pivot axis of the rotating part is X1, the main body pivots around X1 at an angle β to switch between the working state and the storage state, 80≤β<90°, and the length dimension L9≤400mm.

[0012] Preferably, the main body includes a rotating body and an upper locking part, the supporting assembly includes a locking member, a support member, and a rotating part, the rotating body includes a lower locking part, the lower locking part is located below the upper locking part, and the lower locking part and the upper locking part both cooperate with the locking member to lock the main body.

[0013] Preferably, the rotating body includes an outer contour of the rotating body, the main body includes an outer contour of the front side of the main body, and the cover includes an inner boundary of the cover. The outer contour of the rotating body, the outer contour of the front side of the main body and the inner boundary of the cover are adaptively arranged, and the size of the inner boundary of the cover is respectively larger than the outer contour of the rotating body and the outer contour of the front side of the main body.

[0014] Preferably, the pivot axis of the locking member is X2, and the locking member is pivotally mounted on the supporting member and pivots around X2 together with the supporting member.

[0015] In summary, the advantages of the present invention are:

[0016] 1. The layout of the control panel and power supply compartment is optimized, so that the length of the main body along the motor axis is shortened under the condition of the same crushing capacity, and the whole machine is smaller and lighter;

[0017] 2. The control panel is positioned above the motor pivot axis X3 and within the housing between the blanking channel and the power supply compartment. Air inlets are positioned on either side of the housing, keeping them away from the housing to prevent dust from being drawn in and contaminating the internal air path. This reduces the space required for the main body above the rotating unit pivot axis X1, thereby minimizing the overall device footprint.

[0018] 3. Two modes are preset: working state and storage state. They can be flexibly switched around the rotating body during use. A battery pack is detachably installed in the power compartment parallel to the X3. When the crushing device is in the storage state, the battery pack must not be stored in the box, which reduces the overall weight and the size of the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to more clearly illustrate the overall concept of the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following words indicating orientation or positional relationships, such as "upper", "lower", "left", "right", "longitudinal", "lateral", "inner", "outer", "vertical", "horizontal", "top", and "bottom", are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] A crushing device, such as Figures 1 to 14 As shown, there are preset working state and storage state, and the two states can be flexibly switched and used. It mainly includes a main body 4, a cover plate 29 and a support component 5. The cover plate 29 is used as the boundary to roughly divide the whole into the main body 4 on the upper side and the support component 5 on the lower side.

[0043] The main body 4 includes a motor 32, a control panel 33, a rotating body 45, a power supply compartment 44, and a power interface 35 disposed within the compartment 44. The motor 32 pivots along an axis X3, with the power interface 35 positioned parallel to X3. The battery pack 20 can be removably installed in the compartment 44 parallel to X3. The rotating portion 14 pivots along an axis X1, and the main body 4 and the cover 29 are pivotally connected about X1. The main body 4 pivots about X1 through an angle β to switch between the operating and storage states.

[0044] The cover plate 29 and the supporting assembly 5 can be fixedly connected or detachably fixedly connected. However, no matter which connection method is used, the entire device is fixed and integrated in the working state.

[0045] The supporting assembly 5 includes a box body 11. When the crushing device is in working state, the rotating body 45 is located above the box body 11. There is no overlap between the rotating body 45 and the box body 11 in the height direction. The rotating body 45 is located on the upper side of the cover plate 29, and the rotating body 45 partially overlaps with the cover plate 29. When the crushing device is in the storage state, the battery pack 20 must not be stored in the box body 11.

[0046] Combine Figure 1 and Figure 2 As shown, in the working state, the main body 4 rotates around X1 to above the cover plate 29, located outside the box body 11, and the blanking channel 28 is roughly perpendicular to the cover plate 29. From top to bottom, the whole is divided into the upper main body 4 and the lower support assembly 5 with the cover plate 29 as the boundary. The main body 4 and the cover plate 29 are connected along the X1 direction. The cover plate 29 and the support assembly 5 can be fixedly connected or detachably set. Regardless of the connection method, the whole is fixed and integrated in the working state. The main body 4 is provided with a handle 46 for user use, and a power supply compartment 44 for accommodating the battery pack 20. The power supply compartment 44 is provided with a power supply interface 35 parallel to X3. The power supply interface 35 is located above X3 and in the X3 axis. A control panel 33 is provided between the power supply compartment 44 and the blanking channel 28. The main body 4 is provided with an adjustment component 27, a rotating body 45 and an upper locking portion 42. The rotating body 45 is provided with a lower locking portion 451.

[0047] like Figure 3 As shown, other components in the main body 4 are directly or indirectly connected (or arranged) in the main body 4 , and other components in the support assembly 5 are directly or indirectly connected (or installed) on the cover plate 29 .

[0048] The main body 4 also includes a feed port 47, a front panel 41, a transmission assembly 30, a safety switch 31, a knife shaft 23, a knife body 22, an end cover 21, a material removal shaft 26, a fixed knife 25, a rotating body 45, an adjustment assembly 27, etc.

[0049] The supporting assembly 5 further includes a locking member 12 , a supporting member 13 , a rotating portion 14 , a supporting rod 15 , a foot seat 17 , and the like.

[0050] The pulverizing device also includes a transport system and a power system. The transport system mainly includes a handle 46, a box 11, and rollers 16. When transporting, the user can use the rollers 16 to move the pulverizing device in a relatively labor-saving manner. The power system mainly includes a battery pack 20, a power supply compartment 44, a control panel 33, and a motor 32. The motor 32 is a brushless motor or a brushed motor, preferably a brushless outer rotor motor, followed by a brushless inner rotor motor, and finally a brushed motor. When using an AC power supply, the power supply compartment 44 is no longer required on the main body 4. When using a DC power supply, the user plugs in and unplugs the battery pack 20 in a direction parallel to X3 and controls the start, stop, forward, and reverse rotation of the motor 32 through the operation control interface 34 to adjust the working state.

[0051] It is foreseeable that the battery pack 20 can use battery packs 20 with different voltage platforms (18V, 36V, 48V, 72V, etc.) and different specifications (2.5Ah, 3Ah, 4Ah, 5Ah, 6Ah, etc.) as the power source.

[0052] like Figure 2 As shown, the flow direction of the cooling air path R is: air enters from the air inlet 43, flows through the outer surface of the control board 33, the transmission assembly 30, and the motor 32, an air inlet is set on the circumference of the bearing of the motor 32 to introduce the cooling air into the interior of the motor 32, and a centrifugal fan is set at the front end of the motor 32. The cooling air inside the motor 32 is driven by the centrifugal fan to be blown into the box body 11, and then flows out from the air outlet (including the gap L) between the cover plate 29 and the box body 11.

[0053] like Figure 4 In the storage state, the main body 4 rotates around X1 to below the cover plate 29, and most of the entity is located in the box body 11. The blanking channel 28 is roughly parallel to the cover plate 29, and the overall space size is reduced, which is convenient for transportation and storage. With the cover plate 29 as the boundary, the end cover 21 and the front panel 41 face upward, and the main body 4 is locked by the cover plate 29 through the upper locking portion 42. The support member 13 has a supporting portion 131 and an avoidance portion 132, and rotates around X2 on the cover plate 29, as shown in FIG. Figure 5 As shown, it is supported by the cover plate 29 in the clockwise direction and cannot rotate. The support portion 131 is a semi-circular upper opening structure. The locking member 12 is a rotatable structure provided on the support member 13, which has a locking portion 121. The locking portion 121 is in a circular lower opening state, as shown in FIG. Figure 6 As shown, the upper locking portion 42 on the main body 4 is restricted by the locking portion 121 of the locking member 12 and the supporting portion 131 of the supporting member 13 and cannot rotate around X1. At this time, the main body 4 is locked on the cover 29 through the upper locking portion 42.

[0054] By optimizing the layout of the control board 33 and the power supply compartment 44, when the control board 33 is on the upper side of the X3 axis, the height of the entire machine is the smallest when in operation, and the height of the box is also the shortest when in storage. This allows the main body 4 to be shorter along the motor shaft direction while maintaining the same crushing capacity, thereby compressing the spatial dimensions of the entire device and making the entire machine smaller and lighter.

[0055] exist Figure 7 In, such as Figure 7 As shown in a, it is the outer contour 453 of the rotating body 45, L1 is the width dimension of the rotating body 45 away from the X1 side, L2 is the width dimension of the rotating body 45 close to the X1 side, L2>L1, L7 is the width dimension of the lower locking portion 451; Figure 7 As shown in b, it is the outer contour 18 of the front side of the main body 4, L3 is the width dimension of the main body 4 away from the side of X1, L4 is the width dimension of the main body 4 close to the side of X1, L4>L3, L7 is the width dimension of the upper locking portion 42; Figure 7 As shown in c, it is the inner boundary 19 of the cover plate of the support assembly 5 (mainly the cover plate 29), L5 is the width dimension of the support assembly 5 away from the side of X1, L6 is the width dimension of the support assembly 5 close to the side of X1, L6>L5; Figure 7 As shown in Figure d, the inner boundary 19 of the cover, the outer contour 453 of the rotating body, and the outer contour 18 of the front side of the main body have similar external features. The inner boundary 19 of the cover is larger than the outer contour 453 of the rotating body and the outer contour 18 of the front side of the main body. This allows the main body 4 to be stored in the box 11. Among them, L6>L2≥L4, L4≤210㎜, preferably L4=180㎜, and the optimal difference between L6 and L2 (L4) is close to 0, such as 1㎜ is better than 2㎜. L7>L1>L3, (L1 and L3 are the width dimensions of the two contours at the same distance from X1), L7≤250㎜, and L7 is preferably 220㎜.

[0056] like Figure 8 , is a three-dimensional diagram of the crushing device when switching between the working state and the storage state, combined with Figure 3-Figure 5 During the switching process between the working state and the storage state, the locking body 12 rotates, the locking part 121 is rotated to the avoidance part 132 of the support member 13, and the upper locking part 42 (or the lower locking part 451) is unlocked; the upper locking part 42 (or the lower locking part 451) is not in the support part 131.

[0057] like Figures 9-13 When the locking body 12 is in the working state and the storage state, the main body 4 is locked in the supporting assembly 5 through the upper locking portion 42 (or the lower locking portion 451).

[0058] like Figure 9When locked in the retracted state, the locking member 12 and the support member 13 restrict the state of the upper locking portion 42 through the locking portion 121 and the supporting portion 131. The support member 13 is located on the cover plate 29 and is restricted by the cover plate 29, preventing it from rotating clockwise around X2. The supporting portion 131 is located below the upper locking portion 42, restricting the upper locking portion 42 from rotating counterclockwise around X1. The locking member 12 is rotationally connected to the support member 13. When locked, it is restricted by the cover plate 29 and cannot rotate counterclockwise around X2. The locking portion 121 is located above the upper locking portion 42, restricting the upper locking portion 42 from rotating clockwise around X1.

[0059] like Figure 10 When the storage state is unlocked, the locking member 12 releases the lock on the upper locking portion 42, and the locking member 12 is rotationally connected to the support member 13 and rotates around the R1 direction. The locking portion 121 falls into the avoidance portion 132 of the support member 13. The locking portion 121 is no longer on the path of the upper locking portion 42 rotating clockwise around X1, and the lock on the upper locking portion 42 is released. At this time, the upper locking portion 42 can rotate clockwise around X1, and the support member 13 can rotate counterclockwise around X2.

[0060] When the crushing device is in the storage state, the switching process steps to the working state are as follows:

[0061] Step 1: If Figure 11 As shown, the locking member 12 releases the lock on the upper locking portion 42, and the support member 13 rotates counterclockwise around X2 by R2. The main body 4 can rotate clockwise around X1, and the support member 13 can rotate counterclockwise around X2 to avoid the lower locking portion 451. The lower locking portion 451 on the main body 4 rotates clockwise around X1 by R3.

[0062] Step 2: If Figure 12 As shown, the lower locking portion 451 on the main body 4 rotates R3 clockwise around X1, and after rotating to the top of the support portion 131, the support member 13 moves R2' clockwise until it is restricted by 29 and cannot continue to rotate clockwise; the lower locking portion 451 on the main body 4 rotates R3' counterclockwise around X1, and the lower locking portion 451 rotates into the support portion 131.

[0063] Step 3: If Figure 13 The lower locking portion 451 on the main body 4 shown rotates counterclockwise R3' around X1, and the lower locking portion 451 moves into the support portion 131, and the locking portion 121 of the locking member 12 is rotated around R1' to the top of the lower locking portion 451. In the working state, it is the lower locking portion 451 that is locked by the locking member 12, and in the storage state, it is the upper locking portion 42 that is locked by the support member 13.

[0064] Working principle:

[0065] When materials (such as branches, leaves, etc.) need to be crushed, the materials (such as branches, leaves, etc.) are put in from the feed port 47, and are guided by the drop channel 28 to fall between the cutter body 22 and the fixed knife 25. The relative movement of the two forms cutting and extrusion, and finally the materials are crushed into fragments and fall into the box body 11. After the crushing is completed, the user removes the box body 11 from the support component 5 and cleans the debris in the box body 11.

[0066] Example 1

[0067] like Figures 15 and 16 As shown, combined with Figure 2 The length dimension of the main body 4 parallel to the cover plate 29 when in the working state is L9, and the length dimension of the main body 4 parallel to the cover plate 29 when in the storage state is L8, L8>L9, L9≤400mm, preferably L9≤350mm.

[0068] The battery pack 20 uses a battery pack 20a with a rated voltage of 60V and a rated capacity of 8Ah. The battery pack 20a is inserted into the power supply compartment 44 parallel to the X3 direction and electrically connected to the power supply interface 35 to supply power to the motor 32.

[0069] When in working state, the battery pack 20a is at least partially located outside the outer boundary G of the main body 4 pivoting around X1. When in storage state, the main body 4 pivots around X1 at an angle β to switch between working state and storage state, 80≤β<90°. The battery pack 20a needs to be taken out of the power supply compartment 44 before it can be stored in the box body 11, thereby reducing the overall weight and the body volume.

[0070] Example 2

[0071] Different from the first embodiment, Figures 17 to 19 As shown, combined with Figure 2 The length dimension of the main body 4 parallel to the cover plate 29 when in the working state is L9, and the length dimension of the main body 4 parallel to the cover plate 29 when in the storage state is L8, L8>L9, L9≤400mm, preferably L9≤350mm.

[0072] The battery pack 20 uses a battery pack 20b with a rated voltage of 60V and a rated capacity of 4Ah. The battery pack 20b is inserted into the power supply compartment 44 parallel to the X3 direction and electrically connected to the power interface 35 to power the motor 32. The battery pack 20b is roughly hexahedral, with a length of C, a height of D, and a width of E, where C>D and C>E. The battery pack 20b is provided with a battery pack interface 201, which is arranged parallel to the direction of C.

[0073] When in working state, the battery pack 20b is at least partially located outside the outer boundary G of the main body 4 pivoting around X1. When in storage state, the main body 4 pivots around X1 at an angle β to switch between working state and storage state, 80≤β<90°. The battery pack 20b needs to be taken out of the power supply compartment 44 before it can be stored in the box 11, thereby reducing the overall weight and the body volume.

[0074] In addition to the above preferred embodiments, the present invention has other implementation modes. Those skilled in the art can make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
