[0017] A garden hedge trimming device includes a trolley 1, which includes a chassis 2 and wheels 3 mounted on the bottom of the chassis 2. The trolley 1 can be an electric trolley. A push rod 21 is mounted on one end of the chassis 2. Workers push the trolley 1 by pushing the push rod 21. A control panel 22 is mounted on the push rod 21. The control panel 22 is equipped with multiple control buttons, which are all connected to a controller. The multiple control buttons on the control panel 22 can respectively control the start and stop of a first motor 15, a second motor 18, a third motor 30, a fourth motor 33, a first reciprocating hedge trimmer 8, a second reciprocating hedge trimmer 27, and a belt conveyor 11.

[0018] A front support frame 4 is mounted on the top of the chassis 2. The front support frame 4 includes a front vertical beam 5 fixedly mounted on the chassis 2. A front support seat 6 is slidably mounted on the front vertical beam 5. A first drive assembly is installed between the front support seat 6 and the front vertical beam 5. The first drive assembly drives the front support seat 6 to move up and down relative to the front vertical beam 5. The first drive assembly includes a front vertical guide rail 13 and a front vertical rack 14 mounted on the front vertical beam 5. A first motor 15 is mounted on the front support seat 6. A gear that meshes with the front vertical rack 14 is mounted on the output shaft of the first motor 15. A slider that meshes with the front vertical guide rail 13 is also mounted on the front support seat 6. Two front vertical guide rails 13 are mounted on the front vertical beam 5, and the front vertical rack 14 is located between the two front vertical guide rails 13. Both front vertical guide rails 13 are mounted on the side of the front vertical beam 5 opposite to the front support seat 6.

[0019] When the first driving assembly of this invention drives the front support 6 to move up and down relative to the front vertical beam 5, it activates the first motor 15. The first motor 15 drives the gear on it to rotate. Since the gear on the first motor 15 meshes with the front vertical rack 14, the gear on the first motor 15 will drive the first motor 15, the front support 6 fixedly connected to the first motor 15, and the front crossbeam 7 on the front support 6 to move up and down. The front vertical guide rails 13 on both sides guide the front support 6, so that the front support 6 can only move up and down relative to the front vertical beam 5.

[0020] A front crossbeam 7 is slidably mounted on the front support 6. A second drive assembly is installed between the front crossbeam 7 and the front support 6. The second drive assembly drives the front crossbeam 7 to move laterally relative to the front support 6. The second drive assembly includes a front transverse guide rail 16 and a front transverse rack 17 mounted on the front crossbeam 7. A second motor 18 is mounted on the front support 6. A gear that meshes with the front transverse rack 17 is mounted on the output shaft of the second motor 18. A slider that meshes with the front transverse guide rail 16 is also mounted on the front support 6. Two front transverse guide rails 16 are mounted on the front crossbeam 7. Both front transverse guide rails 16 are mounted on the side of the front crossbeam 7 opposite to the front support 6. The front transverse rack 17 is mounted on the bottom surface of the front crossbeam 7.

[0021] In this invention, the first motor 15 and the second motor 18 are fixedly mounted on the front support 6 with bolts. When the second drive assembly drives the front crossbeam 7 to move laterally relative to the front support 6, the second motor 18 is activated, driving the gear on the second motor 18 to rotate. Since the gear on the second motor 18 meshes with the front transverse rack 17, the gear on the second motor 18 drives the front crossbeam 7 to move laterally. The front transverse guide rails 16 on both sides guide the front crossbeam 7, ensuring that the front crossbeam 7 can only move laterally relative to the front support 6.

[0022] A first reciprocating hedge trimmer 8 is installed at one end of the front crossbeam 7, and the blade holder 9 on the first reciprocating hedge trimmer 8 extends forward and laterally to one end of the front crossbeam 7.

[0023] The first reciprocating hedge trimmer 8 and the second reciprocating hedge trimmer 27 of this utility model both adopt the single-blade reciprocating hedge trimmer of the prior art. The first reciprocating hedge trimmer 8 and the second reciprocating hedge trimmer 27 can both adopt the currently available handheld hedge trimmer, and the handheld hedge trimmer is fixed to one end of the front crossbeam 7 or one end of the rear crossbeam 26 by bolts or other connecting parts. Both the first reciprocating hedge trimmer 8 and the second reciprocating hedge trimmer 27 include: a power source, which may be an electric motor; a transmission mechanism, which includes a crank-connecting rod mechanism or an eccentric wheel mechanism that converts the rotational motion of the power source into reciprocating motion; and a cutting mechanism, which includes a blade holder 9 and multiple moving blades. The blade holder 9 is fixedly installed at the front end of the housing of the reciprocating hedge trimmer, serving as the structural base of the cutting mechanism. Multiple fixed blades that cooperate with the moving blades are also fixedly installed on the blade holder 9. The moving blades are reciprocally mounted on the blade holder 9 and cooperate with the fixed blades on the blade holder 9 to cut hedge branches and leaves. The power source drives the moving blades to reciprocate through the transmission mechanism.

[0024] A base plate 10 is also installed on the top of the front crossbeam 7. The base plate 10 is welded to the front crossbeam 7, and multiple stiffening plates are provided between the base plate 10 and the front crossbeam 7. The base plate 10 is connected to the blade holder 9 of the first reciprocating hedge trimmer 8. A baffle 19 is installed on one side of the belt conveyor 11 on the top of the front crossbeam 7.

[0025] One end of the base plate 10 extends forward to the front crossbeam 7. A belt conveyor 11 is installed on the top of the base plate 10. The belt conveyor 11 is arranged vertically, and multiple push plates 12 are installed at intervals on the surface of the belt 20 on the belt conveyor 11.

[0026] The base plate 10 of this invention serves to support the belt conveyor 11 and connect to the blade holder 9 of the first reciprocating hedge trimmer 8. The belt conveyor 11 is vertically mounted on the base. When the belt conveyor 11 is working, the belt 20 of the belt conveyor 11 drives the push plate 12 on it to move. When the push plate 12 moves, it passes directly above the blade holder 9.

[0027] The push plate 12 is mounted obliquely on the belt 20, and the angle between the push plate 12 and the belt 20 on one side of the direction of movement of the belt 20 is an acute angle. By mounting the push plate 12 obliquely on the belt 20, this utility model makes it easier for the push plate 12 to push the pruned branches and leaves at the top of the hedge to the outside of the hedge.

[0028] A rear support frame 23 is mounted on the top of the chassis 2 behind the front support frame 4. The rear support frame 23 includes a rear vertical beam 24 fixedly mounted on the chassis 2. A rear support seat 25 is slidably mounted on the rear vertical beam 24. A third drive assembly is installed between the rear support seat 25 and the rear vertical beam 24. The third drive assembly drives the rear support seat 25 to move up and down relative to the rear vertical beam 24. The third drive assembly includes a rear vertical guide rail 28 and a rear vertical rack 29 mounted on the rear vertical beam 24. A third motor 30 is mounted on the rear support seat 25. A gear that meshes with the rear vertical rack 29 is mounted on the output shaft of the third motor 30. A slider that meshes with the rear vertical guide rail 28 is also mounted on the rear support seat 25. Two rear vertical guide rails 28 are mounted on the rear vertical beam 24, and the rear vertical rack 29 is located between the two rear vertical guide rails 28. Both rear vertical guide rails 28 are mounted on the side of the rear vertical beam 24 opposite to the rear support seat 25.

[0029] When the third drive assembly of this utility model drives the rear support 25 to move up and down relative to the rear vertical beam 24, it activates the third motor 30. The third motor 30 drives the gear on it to rotate. Since the gear on the third motor 30 meshes with the rear vertical rack 29, the gear on the third motor 30 will drive the third motor 30, the rear support 25 fixedly connected to the third motor 30, and the rear cross beam 26 on the rear support 25 to move up and down. The rear vertical guide rails 28 on both sides guide the rear support 25, so that the rear support 25 can only move up and down relative to the rear vertical beam 24.

[0030] A rear crossbeam 26 is slidably mounted on the rear support 25. A fourth drive assembly is installed between the rear crossbeam 26 and the rear support 25. The fourth drive assembly drives the rear crossbeam 26 to move laterally relative to the rear support 25. The fourth drive assembly includes a rear transverse guide rail 31 and a rear transverse rack 32 mounted on the rear crossbeam 26. A fourth motor 33 is mounted on the rear support 25. A gear that meshes with the rear transverse rack 32 is mounted on the output shaft of the fourth motor 33. A slider that meshes with the rear transverse guide rail 31 is also mounted on the rear support 25. Two rear transverse guide rails 31 are mounted on the rear crossbeam 26. Both rear transverse guide rails 31 are mounted on the side of the rear crossbeam 26 opposite to the rear support 25. The rear transverse rack 32 is mounted on the bottom surface of the rear crossbeam 26.

[0031] The third motor 30 and the fourth motor 33 of this invention are fixedly mounted on the rear support 25 by bolts. When the fourth drive assembly drives the rear crossbeam 26 to move laterally relative to the rear support 25, the fourth motor 33 is activated, driving the gear on the fourth motor 33 to rotate. Since the gear on the fourth motor 33 meshes with the rear transverse rack 32, the gear on the fourth motor 33 drives the rear crossbeam 26 to move laterally. The rear transverse guide rails 31 on both sides guide the rear crossbeam 26, ensuring that the rear crossbeam 26 can only move laterally relative to the rear support 25.

[0032] A second reciprocating hedge trimmer 27 is installed at one end of the rear crossbeam 26, and the blade holder 9 on the second reciprocating hedge trimmer 27 extends vertically downward. The second reciprocating hedge trimmer 27 of this invention is used to trim the sides of hedges.

[0033] The working process of this utility model is as follows: When it is necessary to trim the top and sides of the hedge, we first move the first reciprocating hedge trimmer 8 and the second reciprocating hedge trimmer 27 to appropriate positions using the front support frame 4 and the rear support frame 23, respectively. Then, the trolley 1 is moved forward. During the forward movement of the trolley 1, the first reciprocating hedge trimmer 8 trims the top of the hedge, and the second reciprocating hedge trimmer 27 trims the sides of the hedge. While the first reciprocating hedge trimmer 8 is trimming the top of the hedge, the belt conveyor 11 is started, and the belt 20 on the belt conveyor 11 drives the push plate 12 on it to rotate. Driven by the trolley 1, the blade holder 9 moves forward continuously. The branches and leaves pruned by the moving and fixed blades on the first reciprocating hedge trimmer 8 will first move to the upper side of the blade holder 9, and then the pruned branches and leaves will continue to move towards the base plate 10. At the same time, the rotating push plates 12 quickly push the pruned branches and leaves on the blade holder 9 and the base plate 10 along the rotation direction of the belt conveyor 11 to the outside of the hedge, thereby realizing the timely cleaning of the pruned hedge branches and leaves.
