[0027] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.
[0028] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0029] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0030] like Figure 1-4As shown, the utility model provides a grass collecting assembly, including a grass collecting cover, which is arranged above the mowing blade and fixedly connected to the frame 300, and a grass collecting box 100 is fixedly arranged on the frame 300, and the grass inlet of the grass collecting box 100 is connected with the grass outlet of the grass collecting cover through a grass collecting pipe. When in use, the grass cut by the mowing blade is collected by the grass collecting cover, enters the grass collecting pipe, and finally enters the grass collecting box 100 through the grass collecting pipe.
[0031] In this embodiment, the grass collecting assembly further includes an alarm structure, which includes a detection unit disposed in the grass collecting box 100, the detection unit signal is connected to the alarm unit, and the alarm unit is disposed on the frame 300. Specifically, the alarm unit includes an alarm (e.g., a buzzer), and the alarm is fixedly mounted on the frame 300.
[0032] The detection unit is used to detect the amount of grass collected in the grass collecting box 100, and when the amount of grass collected in the grass collecting box 100 reaches a preset value, the alarm unit sounds an alarm.
[0033] During use, as the grass enters the grass collecting box 100, when the detection component detects that the amount of grass collected in the grass collecting box 100 reaches a preset value, the alarm unit sounds an alarm to remind the staff that the grass collecting box 100 is full of grass, thereby avoiding the grass collecting box 100, the grass collecting tube, etc. from being squeezed due to excessive grass in the grass collecting box 100.
[0034] In one embodiment, the detection unit includes a pressure-bearing device disposed in the grass collecting box 100 and a control module 230 electrically connected to the alarm unit. The control module 230 is fixedly mounted on the frame 300 .
[0035] The grass entering the grass collecting box 100 presses down the pressure-bearing device, so that the pressure-bearing device presses the control module 230. When the amount of grass collected in the grass collecting box 100 reaches a preset value, the control module 230 turns on the control circuit of the alarm unit, so that the alarm unit sounds an alarm.
[0036] When in use, the grass cut by the lawn mower enters the grass collecting box 100. As the amount of grass in the grass collecting box 100 increases, the pressure-bearing device is pressed down, causing the pressure-bearing device to press the control module 230. When the amount of grass collected in the grass collecting box 100 reaches a preset value, the pressure-bearing device presses the control module 230 into place, thereby connecting the circuit of the alarm unit to sound an alarm.
[0037] Specifically, the control module 230 may be a control switch (e.g., a normally open push switch) disposed on the control circuit of the alarm unit. When the pressure-bearing device presses the control switch to a closed position, the control circuit of the alarm unit is connected, thereby causing the alarm unit to sound an alarm. The control module 230 may also be a sensor (e.g., a pressure sensor or a position sensor, etc.).
[0038] When the control module 230 is a pressure sensor, the pressure sensor detects that the pressure of the pressure-bearing device on it reaches a preset value, and the pressure sensor transmits a signal to the controller, which controls the alarm unit to sound an alarm.
[0039] When the control module 230 is a position sensor, when the position sensor detects that the pressure-bearing device is pressed down to a preset position, the position sensor transmits a signal to the controller, and the controller controls the alarm unit to sound an alarm.
[0040] In one embodiment, the pressure-bearing device includes a swing arm 210, a first end of the swing arm 210 is hinged to the frame 300, and a second end extends into the grass collecting box 100. The second end of the swing arm 210 is fixedly connected to a pressure plate 220. A pressing portion 211 is provided in the middle of the swing arm 210, and the pressing portion 211 contacts the control module 230 to press the control module 230.
[0041] When in use, the grass entering the grass collecting box 100 presses down the pressure plate 220, thereby moving through the swing arm 210, and the swing arm 210 presses the control module 230 through the pressing part 211. When the amount of grass collected in the grass collecting box 100 reaches a preset value, the pressing part 211 controls the alarm unit through the control module 230 to sound an alarm, so as to achieve the purpose of reminding the staff.
[0042] In one embodiment, the utility model further provides a lawn mower, comprising the grass collecting component described in any of the above embodiments.
[0043] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
