[0029] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The illustrated embodiments are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0030] As Figures 1 to 3 shown, an embodiment of the present utility model provides a grain unloading cylinder position measuring mechanism, including: a rotating cylinder 1, a sensor 2, a fixed cylinder 3, and a circular wedge mechanism 4. One end of the sensor 2 is installed on the fixed cylinder 3, the circular wedge mechanism 4 is installed on the rotating cylinder 1, and the other end of the sensor 2 abuts against the circular wedge mechanism 4.

[0031] The beneficial effect of adopting the technical solution of the present utility model is: when the rotating cylinder rotates, the sensor is deformed by using this mechanism, so as to feedback the specific position of the rotating cylinder. The structure is simple.

[0032] Among them, the user can install the sensor on the rotating cylinder and the circular wedge mechanism on the fixed cylinder according to actual needs. The other end of the sensor 2 and the circular wedge mechanism 4 can be in sliding abutment or rolling abutment.

[0033] A grain unloading cylinder position measuring mechanism provided by an embodiment of the present utility model mainly lies in the mechanical device. The strain gauge sensor (sensor 2) is assembled on the fixed cylinder 3, and a circular wedge mechanism 4 similar to a cam is machined on the rotating cylinder 1. When the rotating cylinder 1 rotates, the strain gauge sensor is deformed by using this mechanism, so as to feedback the specific position of the rotating cylinder 1.

[0034] As Figures 1 to 3As shown, further, a contact roller 5 is installed at the other end of the sensor 2, and the other end of the sensor 2 is in contact with the circular wedge mechanism 4 through the contact roller 5.

[0035] The beneficial effect of adopting the above further technical solution is that when the rotating cylinder rotates, the circular wedge mechanism on the cylinder wall drives the strain gauge sensor to deform through the contact roller. The amount of deformation corresponding to each position of the rotating cylinder is different. After measuring the amount of deformation, the actual position of the rotating cylinder can be digitized. The position measurement has high linearity and a large data expansion space in the later stage.

[0036] Among them, the contact roller 5 is in contact with the outer side surface of the circular wedge mechanism 4.

[0037] As Figures 1 to 3 shown, further, the sensor 2 is a strain gauge sensor.

[0038] The beneficial effect of adopting the above further technical solution is that when the rotating cylinder rotates, this mechanism causes the strain gauge sensor to deform, thereby feeding back the specific position of the rotating cylinder. The position measurement has high linearity and a large data expansion space in the later stage.

[0039] Further, the sensor 2 is connected to a controller.

[0040] The beneficial effect of adopting the above further technical solution is that when the rotating cylinder rotates, the circular wedge mechanism on the cylinder wall drives the strain gauge sensor to deform through the contact roller. The amount of deformation corresponding to each position of the rotating cylinder is different. After measuring the amount of deformation, the actual position of the rotating cylinder can be digitized.

[0041] Among them, the method for the controller to analyze and calculate the data collected by the sensor to obtain the actual position of the rotating cylinder is a prior art. Those skilled in the art can easily think of how to program the controller according to actual needs, and will not be elaborated here.

[0042] As Figures 1 to 3 shown, further, the circular wedge mechanism 4 protrudes from the outer side wall of the rotating cylinder 1.

[0043] The beneficial effect of adopting the above further technical solution is that it is convenient for the circular wedge mechanism to cause the sensor to deform when the rotating cylinder rotates, thereby feeding back the specific position of the rotating cylinder.

[0044] As Figures 1 to 3 shown, further, the circular wedge mechanism 4 is an arc-shaped structure.

[0045] The beneficial effect of adopting the above further technical solution is that it is convenient for the circular wedge mechanism to be adapted to the structure of the rotating cylinder.

[0046] As Figures 1 to 3As shown, further, the radial width of one end of the circular wedge mechanism 4 is greater than the radial width of the other end of the circular wedge mechanism 4.

[0047] The beneficial effect of adopting the above further technical solution is that the amount of deformation corresponding to each position of the rotating cylinder is different. After measuring the amount of deformation, the actual position of the rotating cylinder can be digitalized. The position measurement has high linearity and a large data expansion space in the later stage.

[0048] Among them, the radial width from the other end of the circular wedge mechanism 4 to one end of the circular wedge mechanism 4 gradually increases, showing an increasing trend. Users can also gradually reduce the radial width from the other end of the circular wedge mechanism 4 to one end of the circular wedge mechanism 4 according to actual needs, showing a decreasing trend.

[0049] As Figures 1 to 3 shown, further, one end of the sensor 2 is installed on the fixed cylinder 3 through a fixing bolt 6, and the sensor 2 is an L-shaped structure.

[0050] The beneficial effect of adopting the above further technical solution is that it is convenient for the installation and maintenance of the sensor. The sensor is an L-shaped structure, which is convenient for the sensor to abut against the circular wedge mechanism through the contact roller.

[0051] The utility model utilizes the circular wedge mechanism 4 on the cylinder wall of the rotating cylinder 1 to drive the strain gauge sensor to generate deformation through the contact roller 5 when the rotating cylinder 1 rotates. The amount of deformation corresponding to each position of the rotating cylinder 1 is different. After measuring the amount of deformation, the actual position of the rotating cylinder 1 can be digitalized.

[0052] The key point of a grain unloading cylinder position measuring mechanism provided by an embodiment of the utility model lies in the improvement of the mechanical structure and the structural mode of the measuring position.

[0053] 1. The structure is simple and convenient for production and assembly.

[0054] 2. The position measurement has high linearity and a large data expansion space in the later stage.

[0056] In addition, the utility model also provides a grain unloading cylinder, including the grain unloading cylinder position measuring mechanism described in any one of the above.

[0057] The beneficial effect of adopting the technical solution of the utility model is that when the rotating cylinder rotates, the sensor generates deformation, so as to feedback the specific position of the rotating cylinder. The structure is simple.

[0058] In addition, the utility model also provides a harvester, including the grain unloading cylinder described above.

[0059] The beneficial effects of adopting the technical solution of the present utility model are as follows: when the rotating cylinder rotates, the sensor is deformed, thereby feedbacking the specific position of the rotating cylinder. The structure is simple.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and 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 present utility model.
