One end of the second pipe section 122 is communicated with the air outlet 1302 of the blower 130, and the other end of the second pipe section 122 is communicated with the grass collection box 110. When the blower 130 operates, the grass clippings pass through the first pipe section 121, the blower 130 and the second pipe section 122 in sequence from the grass clipping outlet and then enter the grass collection box 110, completing the collection of the grass clippings during the cutting operation.

[0034] It should be noted that, in this embodiment, for the convenience of connecting the grass conveying pipeline 120 to the fan 130, the grass collecting box 110, and the grass debris outlet, one end of the first pipe section 121 is inserted and connected to the air suction port 1301 of the fan 130, and a hose clamp is provided at the insertion position to lock the connection position through the hose clamp, thereby realizing the connection between the first pipe section 121 and the air suction port 1301 of the fan 130. One end of the second pipe section 122 is inserted and connected to the air outlet 1302 of the fan 130, and similarly, a hose clamp is provided at the insertion position to lock the connection position through the hose clamp to ensure the connection between the second pipe section 122 and the air outlet 1302 of the fan 130.

[0035] In other embodiments, the connection between the first pipe section 121 and the second pipe section 122 and the fan 130 and the grass collecting box 110 can also adopt a combination of connection flanges and bolts, etc., as long as the connection sealing performance of the grass conveying pipeline 120 can be ensured.

[0036] Please refer to Figure 2 , Figure 3 and Figure 10 As shown in, the mounting bracket 150 is fixedly connected to the support frame 160, and the fixed connection method includes but is not limited to detachable bolt connection. The controller 140 includes a housing 141 and a circuit board assembly 142. The control board assembly 142 is disposed inside the housing 141, and the control board assembly 142 is electrically connected to the fan 130 to control the operation of the fan 130. The fan 130 and the controller 140 are integrally mounted on the mounting bracket 150. The mounting method can be bolt fixed connection or snap fixed connection, etc. Optionally, in this embodiment, both the fan 130 and the controller 140 are bolt fixed to the mounting bracket 150. The installation positions of the fan 130 and the controller 140 on the mounting bracket 150 are not limited. For example, the fan 130 and the controller 140 can be arranged vertically or horizontally, etc. The specific structure of the mounting bracket 150 is not limited. For example, it can be a sheet metal welded part or an integrally cast part, etc., as long as it can meet the connection and support strength between the fan 130 and the controller 140 and the support frame 160.

[0037] With such a setting, when the grass collection system 100 needs to be assembled, the fan 130 and the controller 140 can be pre-installed on the mounting bracket 150 in advance to form an installation module. Then, through the mounting bracket 150, the entire installation module is fixedly connected to the support frame 160, and thus the installation of the fan 130 and the controller 140 on the grass collection system 100 can be completed, so the assembly efficiency of the grass collection system 100 can be improved. At the same time, by setting the support frame 160, the grass collection box 110, the fan 130 and the controller 140 can also be integrally installed on the support frame 160. In this way, before the grass collection system 100 and the mower 200 are installed, the installation of the grass collection box 110, the fan 130 and the controller 140 on the support frame 160 can be completed first. During installation, only the support frame 160 needs to be connected to the machine frame 210, and the grass conveying pipeline 120 needs to be connected to the cutting table assembly 220, then the connection between the grass collection system 100 and the mower 200 can be completed, so the installation time between the grass collection system 100 and the mower 200 can be saved. Moreover, when the grass collection system 100 needs to be removed from the mower 200, by removing the connection between the support frame 160 and the mower 200, the removal between the grass collection box 110, the fan 130 and the controller 140 and the mower 200 can be realized, and the removal time between the grass collection system 100 and the mower 200 can be saved.

[0038] It should be noted that when the grass collection system 100 needs to be removed from the mower 200, the connection between the support frame 160 and the machine frame 210 may not be removed, that is, the support frame 160 is retained and installed on the machine frame 210. Only the grass collection box 110 and the mounting bracket 150 connected to the support frame 160 are removed from the support frame 160. Then, the connecting hose clamps at both ends of the first pipe section 121 are removed, and both ends of the first pipe section 121 are respectively pulled out from the air suction port 1301 of the fan 130 and the grass clippings outlet, and thus the removal of the first pipe section 121 can be completed. Then, the connecting hose clamps at both ends of the second pipe section 122 are removed, and both ends of the second pipe section 122 are respectively pulled out from the air outlet 1302 of the fan 130 and the grass collection box 110, and thus the removal of the second pipe section 122 can be completed, thereby completing the removal of the entire grass collection system 100. During this process, neither the fan 130 nor the controller 140 needs to be removed from the mounting bracket 150, that is, they remain in the connected state with the mounting bracket 150. And when the grass collection system 100 needs to be reinstalled on the mower 200, at this time, as long as the mounting bracket 150 is reconnected to the support frame 160, the fixed connection between the fan 130, the controller 140 and the support frame 160 can be realized. Then, both ends of the first pipe section 121 are respectively inserted into the air suction port 1301 of the fan 130 and the grass clippings outlet, and are tightened with a hose clamp; then, both ends of the second pipe section 122 are respectively inserted into the air outlet 1302 of the fan 130 and the grass collection box 110, and are tightened with a hose clamp, and in this way, the installation of the grass collection system 100 on the mower 200 can be completed.

[0039] Please refer to Figure 3 and Figure 4 In an embodiment of the present utility model, the blower 130 includes a motor 131 and a body part 132.

Two protection cavities 151 can also be provided, and the controller 140 and the motor 131 are respectively installed in different protection cavities 151. The structural shape of the protection cavity 151 is not limited, as long as it can protect the controller 140 and the motor 131. By providing the protection cavity 151 on the mounting bracket 150, the protection of the controller 140 and the motor 131 can be realized, and the probability of the controller 140 and the motor 131 being bumped and damaged during the mowing operation can be reduced.

[0040] Optionally, in an embodiment of the present utility model, please refer to Figure 3 and Figure 6 A partition 156 is provided in the protection cavity 151. The partition 156 divides the protection cavity 151 into a first chamber 1511 and a second chamber 1512. The motor 131 is installed in the first chamber 1511, and the controller 140 is installed in the second chamber 1512, as shown in Figure 3 . In other embodiments, it can also be that the motor 131 is installed in the second chamber 1512 and the controller 140 is installed in the first chamber 1511. The first chamber 1511 and the second chamber 1512 can be arranged vertically, or horizontally or longitudinally. Under the condition of meeting the installation requirements of the motor 131 and the controller 140, no specific limitation is made in this embodiment. By providing the first chamber 1511 and the second chamber 1512, the motor 131 and the controller 140 can be separately arranged on the mounting bracket 150, which is convenient for the separate disassembly and assembly of the controller 140 and the motor 131, and is convenient for the replacement and maintenance of the motor 131 and the controller 140.

[0041] Please refer to Figure 3 and Figure 6Furthermore, to facilitate the installation of the motor 131 in the second chamber 1512, a bending bracket 155 is provided at the location where the second chamber 1512 connects to the motor 131. One end of the bending bracket 155 is connected to the wall of the second chamber 1512, and the other end extends toward a side away from the fan housing and forms a mounting surface 1551. The mounting surface 1551 is in close contact with the positioning mounting surface on the motor 131. In this way, by adjusting the raised height of the mounting surface 1551 in the second chamber 1512, a suitable mounting relationship with the motor 131 can be formed without changing other dimensions of the mounting bracket 150, thereby facilitating the installation of the motor 131 in the second chamber 1512.

[0042] See also Figure 3 and Figure 6 Optionally, in one embodiment of the present invention, the first chamber 1511 and the second chamber 1512 are arranged in a vertical direction, that is, the first chamber 1511 and the second chamber 1512 are arranged along the height direction of the lawn mower 200, and the first chamber 1511 is located above the second chamber 1512. The controller 140 is disposed in the first chamber 1511, and the motor 131 is disposed in the second chamber 1512, so that the controller 140 is disposed above the motor 131. In other embodiments, the second chamber 1512 may be located above the first chamber 1511, the controller 140 may be disposed in the second chamber 1512, and the motor 131 may be disposed in the first chamber 1511, as long as the controller 140 is ensured to be located above the motor 131. By arranging first chamber 1511 and second chamber 1512 in a vertical direction, the electrical connection between controller 140 and motor 131 is facilitated, and the connection between controller 140 and motor 131 is made more compact, reducing the lateral size of lawn mower 200 and further reducing the probability of damage to controller 140 and motor 131. Furthermore, since controller 140 is located above motor 131, it can be supported and mounted on partition 156, facilitating installation of controller 140 within protective chamber 151. This also facilitates wiring of controller 140 and facilitates line maintenance in the event of a line fault.

[0043] See also Figure 6, in an embodiment of the present utility model, a weight reduction hole 152 is provided on the side wall of the protection cavity 151. The weight reduction hole 152 can be provided on the side wall of the first chamber 1511 or the side wall of the second chamber 1512. The weight reduction hole 152 can be in various shapes such as triangular, circular, rectangular, etc., specifically to meet the support strength of the first chamber 1511 and the second chamber 1512. By providing the weight reduction hole 152 on the side wall of the protection cavity 151, the weight of the mounting bracket 150 can be reduced, which is more conducive to the lightweight design of the grass collection system 100. At the same time, the support strength and stiffness of the mounting bracket 150 can also be optimized, and the installation stability of the controller 140 and the fan 130 on the support frame 160 can be improved.

[0044] Please refer to Figure 5 and Figure 6 , in an embodiment of the present utility model, the mounting bracket 150 further includes an overhanging portion 153.

Specifically, to improve the connection stability between the mounting bracket 150 and the support frame 160, the overhanging portion 153 includes a mounting portion 1531 and a flanging portion 1532 that are connected to each other. Both the mounting portion 1531 and the flanging portion 1532 are provided with mounting holes for bolts to pass through, so as to form a bolted fixed connection with the support frame 160 in two directions, thereby improving the connection stability between the overhanging portion 153 and the support frame 160, and thus improving the connection stability between the mounting bracket 150 and the support frame 160. By providing the overhanging portion 153 and making the overhanging portion 153 extend to the outside of the protection cavity 151, the connection space between the mounting bracket 150 and the support frame 160 can be increased, which is convenient for connection. At the same time, the shielding of the protection cavity 151 by the overhanging portion 153 will also be reduced, which is convenient for the replacement of the controller 140 and the motor 131.

[0045] In an embodiment of the present utility model, both the controller 140 and the motor 131 are electrically connected to the power source of the lawn mower 200. The power source of the lawn mower 200 can be any device capable of outputting electrical energy, such as a battery pack, a generator set, etc. Optionally, in this embodiment, the power source of the lawn mower 200 is a battery pack, that is, the lawn mower 200 provides kinetic energy through the battery pack for mowing operations.

Specifically, the lawn mower 200 may be provided with an interface at the front end of the vehicle, and both the blower 130 and the control board assembly 142 of the grass collection system 100 are electrically connected to the interface through cables, so as to realize the power supply of the grass collection system 100 by the lawn mower 200. With this setting, the energy supply of the motor 131 and the controller 140 can be realized without separately setting a power source on the grass collection system 100. Therefore, the structure of the grass collection system 100 can be further simplified, the connection between the grass collection system 100 and the lawn mower 200 can be further facilitated, and the control between the motor 131 and the blower (END]]

[0046] It should be noted that in other embodiments, the grass collection system 100 may also include an independent power source, such as a separately provided battery pack, etc. Both the motor 131 and the controller 140 are electrically connected to the independent power source, so as to realize the electrical energy supply of the blower 130.

[0047] Please refer to Figure 3 and Figure 4 , since after the mounting bracket 150 connects the motor 131 and the controller 140, it is equivalent to mounting both the blower 130 and the controller 140 on the mounting bracket 150, so the load weight of the mounting bracket 150 is relatively large. To facilitate the handling of the mounting bracket 150, optionally, in an embodiment of the present utility model, the mounting bracket 150 is provided with a lifting handle 154. The lifting handle 154 can be set at multiple positions convenient for handling the mounting bracket 150, such as above the mounting bracket 150, on the side wall of the mounting bracket 150, etc. Preferably, in this embodiment, the lifting handle 154 is set above the mounting bracket 150, that is, above the first chamber 1511, and the setting position of the lifting handle 154 will not block the controller 140 from entering the first chamber 1511. Specifically, the lifting handle 154 may include a rotating shaft and a shaft sleeve. The rotating shaft passes through the shaft sleeve, and both ends of the rotating shaft extend to the outside of the shaft sleeve and are fixedly connected to the mounting bracket 150. The shaft sleeve is rotatably connected to the rotating shaft. When handling the mounting bracket 150, just grasp the shaft sleeve. In other embodiments, the lifting handle 154 may also be other structures, such as a grip rod structure directly fixedly connected to the mounting bracket 150, a flexible pull rope structure, etc.

[0048] Please refer to Figure 1Since the grass collecting box 110 is located at the rear end of the lawn mower 200, during the mowing process, as the weight of the grass clippings in the grass collecting box 110 increases, the center of gravity of the lawn mower 200 will also move backward. Therefore, when the grass collecting box 110 is full of grass, the lawn mower 200 is prone to tilting when climbing a slope, posing a safety risk to the lawn mower 200. In order to improve the safety performance of the lawn mower 200, optionally, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the lawn mower 200 further includes a counterweight 170, which is disposed on a side of the frame 210 located at the front of the vehicle. The counterweight 170 can be a single block structure or a combination of multiple blocks. The counterweight 170 can be detachably connected to the frame 210, such as by bolts, or can be permanently connected to the frame 210, such as by welding.

[0049] Specifically, in this embodiment, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 The counterweight 170 includes multiple structural blocks 171, a block mounting frame 172, and a pressure rod 173. The block mounting frame 172 is provided with grooves 1721, into which the multiple structural blocks 171 are inserted. The pressure rod 173 presses against the multiple structural blocks 171 and is fixedly connected to the block mounting frame 172 via bolts, thereby achieving a fixed connection between the multiple structural blocks 171 and the block mounting frame 172. The block mounting frame 172 is provided with two cantilever arms 1722. The two cantilever arms 1722 extend toward a side away from the structural blocks 171 and are respectively fixedly connected to the frame 210 of the lawn mower 200 via bolts.

[0050] By installing the counterweight 170, when the mower 200 needs to climb a slope, the counterweight 170 can be installed at the front end of the frame 210. This shifts the center of gravity of the mower 200 forward, thereby reducing the likelihood of the mower 200 tilting when climbing a slope and improving the safety of the mower 200. When the mower 200 is operating on flat ground, the counterweight 170 can be removed from the frame 210, further reducing the weight on the mower 200 and the power consumption during operation, thereby achieving energy conservation and emission reduction effects.

[0051] The grass collection system provided by the utility model integrates the fan and the controller on the mounting bracket. With this arrangement, when the grass collection system needs to be assembled, the fan and the controller can be pre-installed on the mounting bracket in advance to form a mounting module. Then, through the mounting bracket, the entire mounting module is connected to the support frame, and the installation of the fan and the controller on the grass collection system can be completed. Therefore, the assembly efficiency of the grass collection system can be improved. At the same time, by setting the support frame, the grass collection box, the fan and the controller can also be integrally installed on the support frame. In this way, before the grass collection system and the mower are installed, the installation of the grass collection box, the fan and the controller on the support frame can be completed first. Therefore, the installation time between the grass collection system and the mower can be saved; moreover, when the grass collection system needs to be removed from the mower, by removing the connection between the support frame and the mower, the removal of the grass collection box, the fan and the controller from the mower can be achieved, saving the removal time between the grass collection system and the mower. Therefore, the utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.
