Abstract
Description
Technical Field
[0001] This utility model relates to the field of lawnmower technology, specifically to a lawnmower rear-mounted grass collection box connection device. Background Technology
[0002] Lawn mowers use high-speed rotating blades to cut grass stems. A fan is typically installed near the cutting section; its operation generates airflow, which carries the cut grass through a specific channel into a hay collection box. After collecting a certain amount of grass, the box needs to be unloaded for further collection. The hay collection box is usually a separate unit from the mower. Smaller hay collection boxes are often integrally mounted and carried by the mower. However, small hay collection boxes have limited capacity and require multiple unloading cycles after filling, resulting in low efficiency and unsuitability for large lawns. Therefore, we offer a rear-mounted hay collection box connection device for large-capacity hay collection boxes. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a rear grass collection box connection device for a lawnmower, including two sets of fixed brackets 1 and two sets of mounting brackets 2 symmetrically arranged. The lower end of the fixed bracket 1 is fixed to the rear panel 3 of the lawnmower. The fixed brackets 1 are symmetrically distributed on both sides of the grass throwing opening 41 of the grass throwing channel 4. The lower end of the fixed bracket 1 is fixed to the rear panel 3 by bolts. The rear panel 3 is connected to the grass throwing opening 41 of the grass throwing channel 4. The mounting bracket 2 is fixed to the upper end of the fixed bracket 1. The upper end of the fixed bracket 1 is fixed to the mounting bracket 2 by bolts. The mounting end of the mounting bracket 2 is provided with an upper latch 21 and a lower latch 22 respectively. The upper latch 21 and the lower latch 22 are arranged one in front of the other. The opening of the upper latch 21 faces upward and the opening of the lower latch 22 faces downward.
[0024] Mounting frame 2 is detachably mounted to the connecting shaft 51 of the grass collection box 5 via upper latch 21 and lower latch 22. The top of the grass collection box 5 mounted on mounting frame 2 is flush with the lower edge of mounting frame 2. The grass inlet 52 of the grass collection box 5 mounted on mounting frame 2 faces the grass throwing outlet 41 of the grass throwing channel 4. The connecting shaft 51 includes a crossbar 511 and bent rods 512 that are axially movable at both ends of the crossbar 511. The end of the crossbar 511 is locked in the lower latch 22. The bent rod 512 is U-shaped, and the end of the bent rod 512 away from the crossbar 511 is locked in the upper latch 21. The crossbar 511 of the connecting shaft 51 is connected by bearings. The seat 53 is installed on the top of the grass collection box 5 near the grass inlet 52. The bottom of the grass collection box 5 is provided with a wheel 54 on the side away from the grass inlet 52. The curved rod 512 is axially movable and telescopic along the crossbar 511. One end of the curved rod 512 is locked and fixed to the mounting frame 2 by a detachable fastener 5121. The detachable fastener 5121 can be a nut or a pin, and is not limited to these. The nut needs to be rotated to remove it, and the pin can be directly inserted and pulled out. When the detachable fastener 5121 is a nut, the end of the curved rod 512 needs to have a matching thread. When the detachable fastener 5121 is a pin, the end of the curved rod 512 needs to have a matching insertion hole.
[0025] The distance between the two sets of bent rods 512 that are respectively retracted at both ends of the crossbar 511 and the upper latch 21 is smaller than the distance between the upper latches 21 of the two sets of mounting brackets 2.
[0026] The distance between the two sets of bent rods 512 that are respectively unfolded at both ends of the crossbar 511 and the upper clamp 21 is greater than the distance between the upper clamps 21 of the two sets of mounting brackets 2.
[0027] When disassembling the grass collection box 5, simply remove the detachable fastener 5121, and then pull out the bent rod 512 from both ends of the crossbar 511, so that the bent rod 512 disengages from the upper latch 21. Then, the crossbar 511 can be taken out downward within the lower latch 22, thereby separating the connecting shaft 51 of the grass collection box 5 from the mounting bracket 2.
[0028] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
