Description

Technical Field

[0001] The present invention belongs to the technical field of shredders, and more specifically, relates to a shredder. Background Art

[0002] A shredder is an agricultural and forestry machine used to crush branches, leaves and stalks, and is widely used in the crushing of branches, leaves and stalks in agriculture, forestry, animal husbandry and gardens, and is deeply liked by large agricultural growers, large forestry households, ranches, gardens and other individuals or units. After crushing, the branches, leaves and stalks are not only easy to rot and can be reused as organic fertilizers, but the crushed forage is more conducive to storage by herdsmen. Moreover, it can effectively reduce the phenomenon of burning branches, leaves and stalks by fire, greatly reduce the pollution of the surrounding environment by smoke and dust, and is beneficial to human health and ecological balance. At present, some existing shredders pose some threats to the personal safety of operators during use. Specifically, when operators clean, maintain and inspect the machine, it is easy to accidentally trigger the button of the power switch of the machine, resulting in personal injury. Summary of the Invention

[0003] Aiming at the problem of personal injury caused by the misoperation of the operator or the accidental triggering of the button of the power switch of the machine, the purpose of the present invention is to provide a shredder, including a battery pack, a first housing, a second housing and a switch mechanism. The present invention protects the personal safety of the operator through three protection mechanisms. The first protection mechanism is to arrange the battery pack on the first housing, and the battery pack can be detached from the second housing along with the first housing, which can not only keep the center of gravity of the whole machine stable, but also facilitate the disassembly and replacement of the battery pack. The second protection mechanism is to control the on-off of part of the circuit through the connection and separation between the acting part on the first housing and the triggering part on the second housing. When the first housing is separated from the second housing, the acting part is separated from the triggering part to disconnect part of the circuit. At this time, even if the button of the power switch is turned on, it will not cause harm to the personal safety of the operator. The third protection mechanism is the switch knob, which is used to control the on-off of another part of the circuit. When the switch knob controls the disconnection of another part of the circuit, the machine stops operating, ensuring the personal safety of the operator.

[0004] The concept of the present invention is to provide a shredder, which includes a battery pack, a first housing, a second housing, and a switch mechanism; the battery pack is installed on the first housing, the battery pack is movably connected to the first housing, the first housing is detachably installed on the second housing, the battery pack is connected with a first socket, the first socket is arranged on the first housing, and the first socket is connected with the switch mechanism; the switch mechanism includes an acting member installed on the first housing and a triggering member installed on the second housing. When the first housing is connected to the second housing, the acting member and the triggering member are cooperatively connected to connect part of the circuit. When the first housing is separated from the second housing, the acting member and the triggering member are disengaged to disconnect part of the circuit; the switch mechanism further includes a switch knob installed on the first housing, and the switch knob is used to control the on-off of another part of the circuit.

[0005] The first housing is provided with a first connecting member, and the first connecting member is provided with a first convex block and a first groove.

[0006] In some embodiments, the first connecting member is provided with two first convex blocks and two first grooves.

[0007] In some embodiments, the two first convex blocks are respectively arranged on both sides of the first connecting member along the length direction of the first connecting member, the two first grooves are respectively arranged on both sides of the first connecting member along the height direction of the first connecting member, and the two first grooves are located at the top end of the first connecting member.

[0008] The first connecting member is connected with a second connecting member, and the second connecting member is also arranged on the first housing. The second connecting member is provided with a second convex block and a second groove.

[0009] In some embodiments, the second connecting member is provided with two second convex blocks and two second grooves.

[0010] In some embodiments, the two second convex blocks are respectively arranged on both sides of the second connecting member along the length direction of the second connecting member, the two second grooves are respectively arranged on both sides of the second connecting member along the height direction of the second connecting member, and the two second grooves are located at the top end of the second connecting member.

[0011] The second connecting member is cooperatively connected with the first connecting member, and the cooperatively connected second connecting member and first connecting member are provided with a hollow area for accommodating the first socket. Such a setting facilitates the installation and maintenance of the first socket.

[0012] In some embodiments, when the second connecting member is cooperatively connected with the first connecting member, the cooperatively connected second connecting member and first connecting member are provided with two concave portions, the two concave portions are respectively located on both sides of the cooperatively connected second connecting member and first connecting member, and the hollow area communicates with the two concave portions.

[0013] The shredder is provided with two battery packs.

[0014] In some embodiments, the battery packs are standard battery packs, which can enhance the versatility of the shredder and make the shredder not restricted by the types of battery packs.

[0015] The battery pack is provided with a third bump, a fourth bump and a third groove.

[0016] In some embodiments, the battery pack is provided with one third bump, one fourth bump and two third grooves.

[0017] In some embodiments, the third bump, the fourth bump and the third groove are all located on the side where the battery pack is connected to the first socket. The third bump and the fourth bump are both arranged along the width direction of the battery pack, and the third groove is arranged along the length direction of the battery pack.

[0018] The battery pack is movably connected to the first connecting member and the second connecting member.

[0019] In some embodiments, the third bump is respectively in fit connection with the first groove and the second groove, the third groove is respectively in fit connection with the first bump and the second bump, and the fourth bump is used for limiting the battery pack. The fourth bump is stuck at the top of the first connecting member and the second connecting member, so that the battery pack is not easy to move, thus achieving the purpose of fixing the battery pack.

[0020] The battery pack is also movably connected to the first socket.

[0021] In some embodiments, the battery pack is provided with a grid-shaped battery groove, the first socket is provided with two first insertion pieces, and the first insertion pieces are in fit connection with the battery groove.

[0022] The outside of the battery pack is sleeved with a battery pack housing, and the battery pack housing is connected to the first housing.

[0023] In some embodiments, one end of the battery pack housing is connected to the first housing through a first elastic element and a connecting rod, and the other end of the battery pack housing is movably connected to the first housing. When the other end of the battery pack housing is separated from the first housing (i.e., the battery pack housing is in an open state), the first elastic element can drive the other end of the battery pack housing to move towards the first housing, so that the battery pack housing returns to the closed state, reducing the possibility that branches enter the battery pack and affect the operation of the machine.

[0024] In some embodiments, the first elastic element is a first spring.

[0025] In some embodiments, the other end of the battery pack housing is movably connected to the first housing by magnetic attraction. The first housing is provided with a magnetic attraction block, and the battery pack housing is provided with a corresponding magnetic attraction block or an iron block.

[0026] In some embodiments, a fourth groove is provided at one end of the first housing where it is movably connected to the battery pack housing. The fourth groove is used for draining water and preventing water ingress, reducing the possibility of water entering the machine interior from the battery pack housing and causing a short circuit in the circuit.

[0027] The triggering member is a second socket, and a wire is provided between the second socket and the first socket.

[0028] In some embodiments, the wire is arranged along the top of the first housing and is located inside the first housing. With this arrangement, when the first housing is separated from the second housing, the wire can leave the second housing together with the first housing, not only disconnecting part of the circuit but also facilitating the inspection and repair of the machine.

[0029] One end of the wire is connected to the first socket, and the other end of the wire is connected to the acting member. When the first housing is connected to the second housing, the acting member is cooperatively connected to the triggering member, and the circuit between the battery pack and the second socket is turned on.

[0030] The first housing is provided with a fifth bump.

[0031] In some embodiments, the fifth bump is fixedly connected to the first housing.

[0032] In some embodiments, the fifth bump is integrally formed with the first housing, which can further strengthen the connection strength between the fifth bump and the first housing and relatively extend the service life of the machine.

[0033] The fifth bump is movably connected to the switch knob.

[0034] In some embodiments, the fifth bump is rotatably connected to the switch knob.

[0035] The switch knob is connected to a bolt, and a second elastic element is provided between the bolt and the switch knob. When the switch knob is rotated in the closing direction, in addition to the switch knob driving the bolt to loosen, the second elastic element can also drive the bolt to move upward using its own elastic force, so that the bolt will not be unable to move due to being stuck or other reasons when the switch knob is in the closed state, thereby reducing the possibility of causing personal injury to the operator due to the inability to turn off the machine.

[0036] In some embodiments, the second elastic element is a second spring.

[0037] The second housing is provided with a switch connecting member, and a rubber pad is connected to the switch connecting member. The rubber pad is cooperatively connected with the switch connecting member, enhancing the sealing performance of the switch connecting member and also playing a role in waterproofing and dustproofing.

[0038] In some embodiments, the rubber pad is provided with a cross-shaped opening for accommodating the bolt to move. This can ensure the sealing performance of the machine switch to a certain extent without affecting the use of the machine switch.

[0039] The rubber pad is movably connected to the bolt.

[0040] In some embodiments, the rubber pad is sleeved outside the bolt through the cross-shaped opening. When the switch knob is turned towards the closed direction, the bolt loosens, and the second elastic element drives the bolt to move upward using its own elastic force, causing the bolt to leave the rubber pad, reducing the deformation of the rubber pad (especially the cross-shaped opening), relatively prolonging the service life of the rubber pad, and thus relatively reducing costs.

[0041] The bolt is provided with a smooth section, which is arranged at the place where the bolt is connected to the rubber pad. The smooth section is used to limit the movement of the bolt on the rubber pad. Since no thread is provided on the smooth section, the friction between the bolt and the rubber pad can be reduced, thereby reducing the wear of the rubber pad (especially the cross-shaped opening) when the bolt moves on the rubber pad, relatively prolonging the service life of the rubber pad, and thus relatively reducing costs.

[0042] One end of the bolt is connected to the switch knob, and the other end of the bolt is connected to a switch contact. The switch contact is connected to the second socket.

[0043] In some embodiments, the bolt is movably connected to the switch contact. When the switch knob is turned towards the open direction, the bolt moves towards the direction close to the switch contact until the other end of the bolt is connected to the switch contact. At this time, the circuit between the second socket and the switch knob is turned on; when the switch knob is turned to the closed state, the bolt moves towards the direction away from the switch contact, and the other end of the bolt is separated from the switch contact, and the circuit between the second socket and the switch knob is turned off.

[0044] The first housing is connected to the second housing. One end of the second housing is connected to the first housing, and the other end of the second housing is connected to a bottom plate.

[0045] The bottom plate is connected to a pressing branch plate, which is used to assist in feeding.

[0046] In some embodiments, the pressing branch plate is installed on the side of the bottom plate and is located on the side of the bottom plate away from the second housing. Such a setting can not only make reasonable use of space but also facilitate the operator to take the pressing branch plate.

[0047] The bottom plate is connected to a frame, and the frame is connected to two wheels.

[0048] In some embodiments, the two wheels are connected to the frame by a connecting shaft.

[0049] A connecting piece is respectively arranged between the two wheels and the frame.

[0050] In some embodiments, the connecting pieces are respectively sleeved at both ends of the connecting shaft, and a bending part is arranged at one end of the connecting piece close to the frame.

[0051] In some embodiments, the bending part has the same contour radian as the frame. Such a setting can make the connecting piece clamp the frame, so that the wheels are not easily rolled due to the vibration generated during the operation of the machine.

[0052] Technical effects and advantages of the present invention:

[0053] 1. The present invention protects the personal safety of the operator through three protection mechanisms. The first protection mechanism is to arrange the battery pack on the first housing, and the battery pack can be detached from the second housing along with the first housing, which can not only keep the center of gravity of the whole machine stable, but also facilitate the disassembly and replacement of the battery pack; the second protection mechanism is to control the on-off of part of the circuit through the connection and separation between the acting part on the first housing and the triggering part on the second housing. When the first housing is separated from the second housing, the acting part is separated from the triggering part to disconnect part of the circuit. At this time, even if the button of the power switch is turned on, it will not cause harm to the personal safety of the operator; the third protection mechanism is the switch knob, which is used to control the on-off of another part of the circuit. When the switch knob controls the disconnection of another part of the circuit, the machine stops operating, ensuring the personal safety of the operator.

[0054] 2. The present invention controls the circuit from the power supply to the power switch in sections. Only when each section of the circuit is connected, the circuit between the power supply and the power switch will be connected, and the machine will be in the on state. If one section of the circuit is not connected, the machine cannot be turned on. Such a setting can reduce the possibility of personal injury caused by accidentally turning on the switch knob. These three protection mechanisms not only jointly create a safe operating environment for the operator, so that the operator will not be harmed to his own personal safety even if he accidentally touches the switch knob, but also facilitate the installation, inspection and maintenance of the machine, and to a certain extent strengthen the sealing performance and the performance of waterproof and dustproof of the machine, relatively extend the service life of the machine, and relatively reduce the cost.

[0090] The first connecting member 7, the second connecting member 8 and the first housing 2 form two battery pack 1 areas for accommodating the battery pack 1. The shredder is provided with two battery packs 1, and the two battery packs 1 are respectively located in front of and behind the first connecting member 7 and the second connecting member 8. The rear side of the front battery pack 1 is connected to the first socket 4, and the front side of the rear battery pack 1 is connected to the first socket 4. Each battery pack 1 is provided with a third bump 1.1, a fourth bump 1.2 and two third grooves 1.3. The third bump 1.1, the fourth bump 1.2 and the third grooves 1.3 are all located on the side where the battery pack 1 is connected to the first socket 4 (that is, the third bump 1.1, the fourth bump 1.2 and the third grooves 1.3 in the front battery pack 1 are all located on the rear side, and the third bump 1.1, the fourth bump 1.2 and the third grooves 1.3 in the rear battery pack 1 are all located on the front side). The two third grooves 1.3 are both arranged along the height direction of the battery pack 1 (that is, the two third grooves 1.3 are both arranged vertically), and the third bump 1.1 and the fourth bump 1.2 are both arranged along the length direction of the battery pack 1 (that is, the third bump 1.1 and the fourth bump 1.2 are both arranged horizontally). The third bump 1.1 is located in the middle of the battery pack 1, the fourth bump 1.2 is located above the third bump 1.1, the third grooves 1.3 are both located below the third bump 1.1, and the two third grooves 1.3 are respectively located on the left and right sides of the third bump 1.1. The notch of the left third groove 1.3 faces left, and the notch of the right third groove 1.3 faces right.

[0091] The two battery packs 1 are also respectively provided with a battery groove, and the battery groove is in a grid shape. The battery groove and the third bump 1.1 and the third grooves 1.3 are located on the same side of the battery pack 1 (that is, the battery groove of the front battery pack 1 is located on the rear side of the front battery pack 1, and the battery groove of the rear battery pack 1 is located on the front side of the rear battery pack 1). The battery groove is located below the third bump 1.1, and the battery groove is located between the two third grooves 1.3, and the notch of the battery groove faces downward.

[0092] Two battery packs 1 are movably connected to a first connecting member 7 and a second connecting member 8. Specifically: the third protrusions 1.1 of the front battery pack 1 are respectively engaged and connected with the first grooves 7.2 and the second grooves 8.2 in front of the first connecting member 7 and the second connecting member 8; the third grooves 1.3 of the front battery pack 1 are respectively engaged and connected with the first protrusions 7.1 in front of the first connecting member 7 and the second protrusions 8.1 in front of the second connecting member 8; the fourth protrusions 1.2 of the front battery pack 1 are used to limit the front battery pack 1 (the fourth protrusions 1.2 of the front battery pack 1 are stuck at the front tops of the first connecting member 7 and the second connecting member 8, so that the front battery pack 1 is not easily movable, thus achieving the purpose of fixing the front battery pack 1; in addition, the front battery pack 1 and the first connecting member 7 and the second connecting member 8 are movably connected through the engagement of protrusions and grooves, which is not only convenient for installation, but also can achieve the purpose of fixing the battery pack 1 so that it does not easily fall off); the third protrusions 1.1 of the rear battery pack 1 are respectively engaged and connected with the first grooves 7.2 and the second grooves 8.2 behind the first connecting member 7 and the second connecting member 8; the third grooves 1.3 of the rear battery pack 1 are respectively engaged and connected with the first protrusions 7.1 behind the first connecting member 7 and the second protrusions 8.1 behind the second connecting member 8; the fourth protrusions 1.2 of the rear battery pack 1 are used to limit the rear battery pack 1 (the fourth protrusions 1.2 of the rear battery pack 1 are stuck at the rear tops of the first connecting member 7 and the second connecting member 8, so that the rear battery pack 1 is not easily movable, thus achieving the purpose of fixing the rear battery pack 1; in addition, the rear battery pack 1 and the first connecting member 7 and the second connecting member 8 are movably connected through the engagement of protrusions and grooves, which is not only convenient for installation, but also can achieve the purpose of fixing the battery pack 1 so that it does not easily fall off).

[0093] The two battery packs 1 are also respectively movably connected to a first socket 4. The battery grooves of the front battery pack 1 are engaged and connected with the front half of the first inserts of the first socket 4, and the battery grooves of the rear battery pack 1 are engaged and connected with the rear half of the first inserts of the first socket 4.

[0094] The outside of the battery pack 1 is sleeved with a battery pack housing 9. The battery pack housing 9 is connected to the first housing 2. The left lower end of the battery pack housing 9 and the first housing 2 are connected by a first elastic element 10 (here, the first elastic element 10 is a first spring, or it can also be other elastic elements) and a connecting rod 11. The upper right end of the battery pack housing 9 and the first housing 2 are movably connected by a magnetic attraction method (operating to open and close the battery pack housing 9 by the magnetic attraction method is simple. Of course, the upper right end of the battery pack housing 9 and the first housing 2 can also be movably connected by other methods). The first housing 2 is provided with a magnetic attraction block, and the upper right end of the battery pack housing 9 is provided with a corresponding magnetic attraction block (or an iron block). When the upper right end of the battery pack housing 9 is separated from the first housing 2 (that is, when the battery pack housing 9 is in the open state), the first elastic element 10 can drive the left lower end of the battery pack housing 9 to move, thereby driving the upper right end of the battery pack housing 9 to move towards the first housing 2. Coupled with the magnetic attraction between the upper right end of the battery pack housing 9 and the first housing 2, the battery pack housing 9 is restored to the closed state, reducing the possibility of branches entering the battery pack 1 and affecting the operation of the machine); One end of the first housing 2 connected to the upper right end of the battery pack housing 9 is provided with a fourth groove 12. The fourth groove 12 is located above the battery pack 1 (the fourth groove 12 is used for draining water and preventing water ingress. Such a setting can reduce the possibility of water entering the machine interior from the battery pack housing 9 and causing a short circuit in the circuit).

[0095] The first socket 4 is connected to the switch mechanism. The switch mechanism includes an acting member mounted on the first housing 2 and a triggering member 5 on the second housing 3 (when the first housing 2 is connected to the second housing 3, the acting member and the triggering member 5 are cooperatively connected to connect part of the circuit. When the first housing 2 is separated from the second housing 3, the acting member and the triggering member 5 are disengaged to disconnect part of the circuit). The triggering member 5 is a second socket. A wire 13 is provided between the second socket and the first socket 4. The wire 13 is arranged along the top of the first housing 2 and is located inside the first housing 2 (such a setting enables the wire 13 to leave the second housing 3 together with the first housing 2 when the first housing 2 is separated from the second housing 3. This can not only disconnect part of the circuit but also facilitate the inspection and repair of the machine). The left end of the wire 13 is connected to the first socket 4, and the right end of the wire 13 is connected to the acting member (when the first housing 2 is connected to the second housing 3, the acting member and the triggering member 5 are cooperatively connected, and the circuit between the battery pack 1 and the second socket is turned on. At this time, the circuit is battery pack 1 - first socket 4 - wire 13 - acting member - triggering member 5).

[0096] The switch mechanism further includes a switch knob 6 mounted on the first housing 2. The switch knob 6 is used to control the on / off of another part of the circuit. The first housing 2 is provided with a fifth bump 15 that cooperates with the switch knob 6. The fifth bump 15 is fixedly connected to the first housing 2 (specifically, the fifth bump 15 is integrally formed with the first housing 2, which can further strengthen the connection strength between the fifth bump 15 and the first housing 2 and relatively extend the service life of the machine). The fifth bump 15 is located outside the first housing 2 and on the upper surface of the first housing 2. The fifth bump 15 is movably connected to the switch knob 6 (here, the movable connection means that the upper end of the fifth bump 15 is rotationally connected to the switch knob 6).

[0097] The switch knob 6 is connected to a bolt 14. The bolt 14 is located at the lower end of the switch knob 6. A second elastic element 16 (here, the second elastic element 16 is a second spring, or it can also be other elastic elements) is provided between the bolt 14 and the switch knob 6. The second elastic element 16 is sleeved on the upper end of the bolt 14 and is located inside the switch knob 6 (when the switch knob 6 is rotated in the closing direction, in addition to the switch knob 6 driving the bolt 14 to loosen, the second elastic element 16 can also use its own elastic force to drive the bolt 14 to move upward, so that the bolt 14 will not be unable to move due to being stuck or other reasons when the switch knob 6 is in the closed state, thereby reducing the possibility of personal injury to the operator caused by the inability to turn off the machine).

[0098] The second housing 3 is provided with a switch connecting member 17. The switch connecting member 17 is connected to a rubber pad 18. The rubber pad 18 is located at the middle position of the switch connecting member 17 (it can be understood that the center of the rubber pad 18 and the center of the switch connecting member 17 are the same center). The rubber pad 18 is cooperatively connected to the switch connecting member 17 (the rubber pad 18 strengthens the sealing performance of the switch connecting member 17 and also plays a role in waterproofing and dustproofing). The rubber pad 18 is provided with a cross-shaped opening (the cross-shaped opening is used to accommodate the bolt 14 for movement, which can, to a certain extent, ensure the sealing performance of the machine switch and does not affect the use of the machine switch). The cross-shaped opening is located at the center of the rubber pad 18. The rubber pad 18 is movably connected to the bolt 14. The rubber pad 18 is sleeved on the outside of the bolt 14 through the cross-shaped opening (when the switch knob 6 is rotated in the closing direction, the bolt 14 loosens, and the second elastic element 16 uses its own elastic force to drive the bolt 14 to move upward so that the bolt 14 leaves the rubber pad 18, reducing the deformation of the rubber pad 18, especially the cross-shaped opening, relatively extending the service life of the rubber pad 18, and thus relatively reducing the cost).

[0099] The bolt 14 is provided with a smooth section, which is arranged at the place where the bolt 14 is connected to the rubber pad 18 (i.e., the lower end of the bolt 14), and the diameter of the smooth section is smaller than the diameter of other parts of the bolt 14 except the smooth section (it can also be understood that a groove is provided at the lower end of the bolt 14, and the groove is distributed along the circumferential direction of the bolt 14). The smooth section is used to limit the movement of the bolt 14 on the rubber pad 18 (when the switch knob 6 rotates, it will drive the bolt 14 to move up and down. At this time, the smooth section of the bolt 14 also moves up and down at the cross opening of the rubber pad 18. Since there is no thread on the smooth section, the friction between the bolt 14 and the rubber pad 18 can be reduced, thereby reducing the wear of the rubber pad 18 when the bolt 14 moves on the rubber pad 18, especially at the cross opening, relatively extending the service life of the rubber pad 18, and thus relatively reducing the cost).

[0100] The upper end of the bolt 14 is connected to the switch knob 6, and the lower end of the bolt 14 is connected with a switch contact. The upper end of the switch contact is movably connected to the lower end of the bolt 14, and the lower end of the switch contact is connected to the second socket. Specifically, when the switch knob 6 is rotated in the opening direction, the bolt 14 moves towards the direction close to the switch contact until the other end of the bolt 14 is connected to the switch contact. At this time, the circuit between the second socket and the switch knob 6 is turned on; when the switch knob 6 is rotated to the closed state, the bolt 14 moves away from the switch contact, and the other end of the bolt 14 is separated from the switch contact, and the circuit between the second socket and the switch knob 6 is disconnected.

[0101] The upper end of the second housing 3 is connected to the first housing 2, the lower end of the second housing 3 is connected with a bottom plate 19, and the bottom plate 19 is connected with a pressing plate 20. The pressing plate 20 is used to assist in feeding (specifically, when the feeding port is blocked by branches, leaves and stems, the operator can use the pressing plate 20 to press the branches, leaves and stems blocking the feeding port into the shredder, so as to help more branches, leaves and stems enter the shredder for crushing). The pressing plate 20 is installed behind the bottom plate 19, and the pressing plate 20 is located below the bottom plate 19 (there is sufficient space below the bottom plate 19 for accommodation. Such a setting can not only make reasonable use of space, but also facilitate the operator to take the pressing plate 20). The pressing plate 20 is provided with a handle, and the handle is arranged at the right end of the pressing plate 20 (further facilitating the operator to take the pressing plate 20).

[0102] The bottom plate 19 is connected to the machine frame 21. The machine frame 21 includes two connecting brackets 21.1 and a chassis 21.2. The two connecting brackets 21.1 are respectively fixedly connected to the chassis 21.2 (here, the fixed connection means that the two connecting brackets 21.1 and the chassis 21.2 are integrally formed, so that the overall strength of the machine frame 21 is relatively strong, not easily damaged, relatively extending the service life and relatively reducing the cost). The upper ends of the two connecting brackets 21.1 are respectively connected to the left end of the bottom plate 19, and the two connecting brackets 21.1 are distributed front and back. The lower ends of the two connecting brackets 21.1 are respectively connected to the right end of the chassis 21.2. The chassis 21.2 is U-shaped and opens to the right (a material receiving member can be placed above the chassis 21.2 to collect the crushed branches, leaves and stalks). The lower end of the front connecting bracket 21.1 is connected to the front end of the chassis 21.2, and the lower end of the rear connecting bracket 21.1 is connected to the rear end of the chassis 21.2. Looking from the front to the back (as shown in the appendix Figure 1 ), the machine frame 21 is V-shaped and opens to the left. The machine frame 21 is connected with two wheels 22. A connecting shaft 23 is arranged between the two wheels 22. The two wheels 22 are respectively connected to the front and rear ends of the chassis 21.2 through the connecting shaft 23. A connecting member 24 is respectively arranged between the two wheels 22 and the chassis 21.2. The two connecting members 24 are respectively sleeved on the front and rear ends of the connecting shaft 23, and a bending part is arranged at one end of the connecting member 24 close to the machine frame 21. The bending part has the same contour arc as the machine frame 21 (it can be understood that a bending part is arranged at the rear end of the front connecting member 24, and the bending part is located on the left and right sides of the rear end of the front connecting member 24, and the shape of the bending part is the same as the shape in front of the front end of the chassis 21.2; a bending part is also arranged at the front end of the rear connecting member 24, and the bending part is located on the left and right sides of the front end of the rear connecting member 24, and the shape of the bending part is the same as the shape behind the rear end of the chassis 21.2; such a setting can make the connecting member 24 clamp the machine frame 21, so that the wheels 22 are not easily rolled due to the vibration generated during the operation of the machine).
