This utility model discloses a detachable fabric-covered V-belt for garden machinery. This utility model relates to the field of garden machinery technology. The utility model includes: a housing; a quick-release device rotatably connected to the inner wall of the housing; the quick-release device is detached by rotation; and a tension device is slidably connected to the inner wall of the housing. By cooperating with the quick-release device and the tension device, rotating the rotating rod causes the sliding block and the limiting ring to move. The locking block, under the action of a compression spring and a spring pin, disengages from the limiting position of the fixed block, allowing the fabric-covered V-belt to quickly separate from the quick-release device. The rotatable connection between the locking block and the inner wall of the fixed block, combined with the design of the compression spring and spring pin, ensures that the locking block can accurately engage with the fixed block during installation of the fabric-covered V-belt. The spring pin, under the action of the compression spring, provides a stable limiting force, ensuring a secure connection between the fabric-covered V-belt and the quick-release device, and preventing the fabric-covered V-belt from loosening and falling off due to vibration or other factors during the operation of the garden machinery.

A tray collection transfer plate car, including the bottom support of concave character structure, a plurality of rotating seats are welded on the two parallel lower walls of the bottom support, the lower end of the rotating seat is rotatably provided with a pair of rollers through an axle, the rollers are located on the inner and outer sides of the rotating seat, the front end of the two parallel upper walls of the bottom support is welded with a concave seat, the upper end of the concave seat is rotatably provided with a rotating head through a rotating shaft, the upper end of the rotating head is welded with an I-shaped plate with an I-shaped structure, the front end of the I-shaped plate is welded with a pair of baffle plates, the rear end of the I-shaped plate is abutted to the upper end of the supporting seat. The baffle plate and the baffle strip set play a limiting role on the front side of the tray, and in order to make the tray closely adhere to the inner wall of the baffle plate and the baffle strip, the limiting effect on the tray is improved.
