Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

Referring to fig. 1-3, a schematic structural diagram of an embodiment of the present invention provides an axial-flow type grass fullness indicating device, which is installed on a grass collecting pipe 5 of a grass mower, and includes an installation seat 1 and an indicating wind wheel 2 rotatably installed in the installation seat 1, the installation seat 1 is fixed on an outer wall of the grass collecting pipe 5, a containing cavity is provided in the installation seat 1, the indicating wind wheel 2 is rotatably installed in the containing cavity, an air inlet 1-2a is provided at one side of the containing cavity close to the outer wall of the grass collecting pipe 5, an air outlet 1-1a is provided at one side close to the inner wall of the grass collecting pipe 5, an air flow channel is formed between the air inlet 1-2a and the air outlet 1-1a, when the grass mower works, dry branches, rotten leaves, crushed grass and the like on a grass land enter a grass collecting bag 6 through the grass collecting pipe 5, the containing cavity generates negative pressure under the action of air flow in the grass collecting pipe 5 to indicate the rotation of the wind wheel 2, when grass collecting bag 6 is full or grass collecting pipe 5 is blocked, the airflow is reduced, and the rotating speed of wind wheel 2 is indicated to be reduced to stop, so that the indication function is achieved, and an operator is prompted to clear the grass.

Specifically, the mounting seat 1 comprises a lower shell 1-1 and an upper shell 1-2 detachably arranged on the lower shell 1-1, wherein the lower shell 1-1 extends into the straw collecting pipe 5 and forms an air outlet 1-1a, and the upper shell 1-2 is provided with an air inlet 1-2 a. The upper shell 1-2 and the lower shell 1-1 are fixed on the outer wall of the grass collecting pipe 5 through bolts. Preferably, the upper casing 1-2 and the lower casing 1-1 are connected by a snap fit, which is a conventional technique, for example, a plurality of snap fit portions 1-2b are provided at intervals on the lower end of the upper casing 1-2, and corresponding snap fit grooves 1-1b are provided on the lower casing 1-1.

In order to facilitate the formation of negative pressure in the accommodating cavity and avoid sundries in the grass collecting pipe 5 from entering the accommodating cavity, the end surface of the air outlet 1-1a close to the inner wall of the grass collecting pipe 5 is arranged in a high-low manner from the upstream direction to the downstream direction of the grass collecting direction, namely the end surface positioned at the upstream is closer to the central position of the grass collecting pipe 5 than the end surface positioned at the downstream, in this case, the end surface positioned at the air outlet 1-1a is obliquely arranged.
