Wherein the mounting box 3344 is mounted to the front side of the upper back plate portion 3321, and the second swing arm 3343 and the hall switch 3345 are disposed within the mounting box 3344. The spring plate 3341 is mounted to the rear side of the upper back plate portion 3321. One end of the first swing arm 3342 is rotatably connected to the mounting box 3344, and the other end of the first swing arm 3342 extends to the rear end of the elastic sheet 3341 through the upper back plate portion 3321. The magnet 3345a of the hall switch 3345 is mounted on the second swing arm 3343, and the sensor 3345b of the hall switch 3345 is mounted on the inner wall of the mounting box 3344. The first swing arm 3342 is in transmission connection with the second swing arm 3343. In some embodiments, the first swing arm 3342 is splined to the second swing arm 3343. In some embodiments, the grass-collection detection device 334 also includes a spring 3346 disposed within the mounting box 3344. One end of the spring 3346 abuts against the inner wall of the mounting box 3344, and the other end abuts against the second swing arm 3343.

The grass collection detection device 334 operates according to the following principle: when the accommodating device 31 is mounted to the mounting position, the elastic sheet 3341 is pressed, the elastic sheet 3341 drives the first swing arm 3342 to rotate relative to the mounting box 3344, the first swing arm 3342 drives the second swing arm 3343 to synchronously rotate, and the second swing arm 3343 compresses the spring 3346 and drives the magnet 3345a to be close to the sensor 3345b, so as to trigger the hall switch 3345. In this way, by providing the grass collection detection device 334, the safety performance of the riding mower 100 can be improved, and the user is prevented from starting the mowing function when the housing device 31 is not mounted. When the accommodating device 31 is removed from the mounting position, the second swing arm 3343 rotates in the opposite direction under the action of the spring 3346, so as to drive the magnet 3345a of the hall switch 3345 to be away from the sensor 3345b, and enter the non-triggered state from the triggered state, the second swing arm 3343 drives the first swing arm 3342 to synchronously rotate in the rotating process, and the second swing arm 3343 drives the elastic sheet 3341 to restore to the original position.

The installation box 3344 of the grass collecting and detecting device 334 in the embodiment adopts a closed design, can prevent water and dust, and has higher safety performance. In some embodiments, the first swing arm 3342 is designed as a circular arc hook, which can reduce the opening of the upper back plate portion 3321, prevent the accumulation of broken grass, and cause the risk of jamming of the first swing arm 3342. In addition, in the riding mower 100, jolt occurs during traveling, and in order to reduce the influence of the storage device 31 on the grass collection detection device 334 during jolt, the reason for selecting the hall switch to implement the function of the grass collection detection device 334 in this embodiment is that the hall switch needs to have a certain stroke to be triggered. Of course, other forms of detection means may be employed by those skilled in the art to detect whether the receiving means 31 is installed.

During operation of the riding mower 100, when the grass clippings in the accommodating device 31 affect the grass inlet to feed grass, a user needs to topple over. Conventional riding mowers typically determine from the experience of the user whether the cutting in the receptacle 31 needs to be dumped, often either too early or too late. In order to accurately judge the dumping time of the accommodating device, the accommodating device needs to be checked for many times, and the working efficiency is affected.

The riding mower 100 of the present application also has the function of automatically alerting the user of grass fullness. It will be appreciated that when the clippings in the receptacle 31 reach the amount to be removed, the user is able to know without getting off the vehicle. Referring to fig. 5 and 14a to 15, the riding mower 100 further includes a grass full detection device 335 for detecting the state of grass clippings in the housing device 31. The grass full detection device 335 is disposed on the back plate assembly 33 below the grass outlet 321.

Specifically, the grass full detection device 335 includes a mounting box 3351, a first swing arm 3352, a second swing arm 3353, a telescopic rod 3354, and a switch 3355. Wherein the mounting box 3351 is fixedly mounted to the lower back plate portion 3322 and disposed on the front side of the lower back plate portion 3322. The second swing arm 3353 and the switch 3355 are disposed in the mounting box 3351. One end of the first swing arm 3352 is rotatably connected to the mounting box 3351, and the other end extends into the housing device 31 through the lower back plate portion 3322. In this embodiment, the switch 3355 is a hall switch, the magnet 3355a is mounted on the second swing arm 3353, and the sensor 3355b is mounted on the inner wall of the mounting box 3351. The first swing arm 3352 is in driving connection with the second swing arm 3353. In some embodiments, the first swing arm 3352 is splined to the second swing arm 3353. In some embodiments, the grass full detection device 335 also includes a spring 3356 disposed within the mounting box 3351. One end of the spring 3356 abuts against the inner wall of the mounting box 3351, and the other end abuts against the second swing arm 3353. Of course, the switch 3355 may be in different switch forms, and the positions thereof may be selected differently, which will be arranged by those skilled in the art according to the actual situation.

The grass-full detection device 335 operates as follows: when the grass clippings enter the accommodating device 31 from the grass outlet 321, the grass clippings are accumulated upwards from the bottom of the accommodating device 31 and gradually pressed on the first swing arm 3352, when the grass clippings pressed on the first swing arm 3352 reach a certain weight, the first swing arm 3352 rotates downwards relative to the mounting box 3351, the first swing arm 3352 drives the second swing arm 3353 to synchronously rotate, and the second swing arm 3353 compresses the spring 3356 and drives the magnet 3355a to be close to the sensor 3355b, so that the switch 3355 is triggered. In this way, by providing the grass full detection device 335, the state of the grass scraps in the storage device can be automatically detected, so that the user can accurately judge the time for cleaning the storage device 31 without checking the storage device 31. When the grass scraps in the accommodating device 31 are cleaned or the accommodating device 31 is removed, the force applied to the first swing arm 3352 is reduced or eliminated, and the second swing arm 3353 rotates in the opposite direction under the action of the spring 3356, so that the magnet 3355a of the switch 3355 is driven to be far away from the sensor 3355b, the triggered state is brought into the non-triggered state, and the second swing arm 3353 drives the first swing arm 3352 to synchronously rotate in the rotating process so as to restore to the original position.

Of course, the user can adjust the plugging length of the telescopic rod 3353 on the first swing rod 3352 according to the variety of grass, different mowing heights and different conditions of hay or wet grass, so that when a grass discharging signal is sent, the grass outlet 321 is basically full and is not blocked by grass scraps, and normal grass discharging during mowing is ensured.

In some embodiments, the grass-fill detection device 335 also includes a telescoping rod 3354. The telescopic rod 3354 is sleeved on the first swing rod 3352. Specifically, the telescoping rod 3354 has a first state as shown in fig. 14a and a second state as shown in fig. 14 b. It will be appreciated that when the grass full detection device 335 outputs a grass full signal when the telescoping rod 3354 is in the first state and the second state, the grass collection rate in the housing device 31 is different. For example, when the lawn being worked by riding mower 100 is hay or grass is dry, the user adjusts telescoping lever 3354 to the first condition shown in fig. 14 a. When the lawn on which riding mower 100 is operating is wet, the user can adjust telescoping lever 3354 to the second condition shown in fig. 14 b. Like this, through set up telescopic link 3354 on first pendulum rod 3352, can adjust the state of grass full detection device 335 according to the operating mode adaptively, the user of convenience adjusts the grass percentage when reminding of grass full.
