Description

Technical Field

[0001] This application relates to the field of membrane roll support, and more specifically, to a membrane roll support structure that is resistant to falling and easy to replace. Background Technology

[0002] The film covering work of rice transplanters requires the film roll to be installed on the rice transplanter, and then the film is pulled out from the film roll to cover the rice. However, the replacement of the film roll is relatively troublesome. Generally, both ends of the film roll need to be removed to replace the film, which affects the replacement speed and increases the workload.

[0003] A membrane roll support structure that prevents falling and is easy to replace is now provided to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a membrane roll support structure that is drop-proof and easy to replace, comprising: two membrane supports, each membrane support having a shaft groove, the lower side of which is semi-circular and chamfered at the connection point with the upper end; a membrane shaft can be placed in the two shaft grooves; a membrane roll can be inserted into the membrane shaft; two axle wheels are fitted with the membrane shaft with clearance fit and installed along the axis of the membrane shaft; each axle wheel has an annular groove in the middle; wherein the shaft grooves are open on both sides along the axis of the membrane shaft, and the shaft grooves are located away from the membrane support mounting portion. The annular groove has an opening on one side of the wall. The width of the annular groove is greater than the length of the membrane support along the axis of the membrane shaft. The cross-sectional shape of the annular groove is an isosceles trapezoid, which allows the axle wheel to have a certain tilting angle when it is engaged on both sides of the membrane support. This facilitates the movement of one end of the membrane shaft during the loading and unloading of the membrane roll, causing the axle wheel at the other end to tilt within the groove. By having one end of the membrane shaft leave one side of the groove, only one person is needed to replace the membrane roll on either side. The chamfer at the connection between the lower and upper ends of the groove facilitates the axle wheel entering the semi-circular shape at the lower end of the groove.

[0006] Furthermore, The upper wall of the shaft groove is arc-shaped and fits the shape of the annular groove in the shaft wheel.

[0007] Furthermore, The opening size of the shaft groove is larger than the size of the annular groove in the shaft wheel.

[0008] Furthermore, The inner end wall of the shaft groove is made of wear-resistant material, and the inner end wall of the shaft groove is detachably fixed with elastic wear-resistant material.

[0009] Furthermore, The membrane shaft has two detachable fixed connections with respect to the membrane rolls, and the two inner pins can limit the position of the two membrane rolls.

[0010] Furthermore, The membrane shaft has two detachable fixed connections with two outer pins symmetrical about the shaft wheel. The outer pins and the nearest inner pin together limit the position of the shaft wheel.

[0011] Furthermore, When the two shaft wheels are positioned, the distance between the annular grooves inside the two shaft wheels is the same as the distance between the two membrane supports, which allows the two shaft wheels to be inserted into the two shaft grooves, and the shaft wheels are positioned in the shaft grooves by the outer diameter portion of the two shaft wheels.

[0012] The beneficial effects of this application are as follows: It provides a membrane roll support structure that prevents falling and is easy to replace. By setting a shaft wheel, and through the cooperation between the inner annular groove of the shaft wheel and the inner shaft groove of the membrane support, it is possible to allow one end of the membrane roll shaft to leave the membrane support independently while the other end is still limited by the membrane support. Only one person is needed to replace the membrane roll on either side, which changes the previous operation process that required two people to replace the membrane roll, saving manpower and effort.

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1, refer to Figure 1 Figure 2 illustrates a film roll support structure that is resistant to falling and easy to replace, comprising: two film supports 5, which can be installed and fixed on a rice transplanter; each film support 5 has a shaft groove 7 with one side opening; the lower side of the shaft groove 7 is semi-circular and chamfered at the connection point with the upper end; a film shaft 6 can be placed in the two shaft grooves 7; a film roll 4 can be inserted into the film shaft 6; two shaft wheels 2 are fitted with the film shaft 6 with clearance fit and installed along the axis of the film shaft 6; each shaft wheel 2 has an annular groove in the middle; wherein, the shaft groove 7 is open on both sides along the axis of the film shaft 6, and the upper side of the shaft groove 7 away from the mounting part of the film support 5 is open; the annular groove... The width is greater than the length of the membrane support 5 along the axis of the membrane shaft 6. The cross-sectional shape of the annular groove is an isosceles trapezoid, which allows the shaft wheel 2 to have a certain tilt angle movement space when it is locked on both sides of the membrane support 5. This facilitates the movement of one end of the membrane shaft 6 with the other end of the shaft wheel 2 in the shaft groove 7 when loading and unloading the membrane roll 4. By having one end of the membrane shaft 6 leave one side of the shaft groove 7, only one person is needed to replace the membrane roll 4 on either side, which changes the previous operation process that required two people to replace the membrane roll, saving manpower and effort. The chamfer at the connection position between the lower and upper ends of the shaft groove 7 facilitates the shaft wheel 2 to enter the semi-circular shape at the lower end of the shaft groove 7.

[0023] The upper wall of the shaft groove 7 is arc-shaped and fits the shape of the annular groove in the shaft wheel 2. This facilitates the limiting of the shaft wheel 2 when it is lifted upwards, and also increases the contact area between the shaft wheel 2 and the upper wall of the shaft groove 7 when it is lifted upwards. This avoids collision damage to the membrane shaft 6 and the shaft groove 7 caused by the small contact area between the shaft wheel 2 and the shaft groove 7 when it is lifted.

[0024] The opening size of the shaft groove 7 is larger than the size of the annular groove in the shaft wheel 2, which facilitates the transfer of the shaft wheel 2 away from the shaft groove 7.

[0025] The inner end wall of the shaft groove 7 is made of wear-resistant material, and the inner end wall of the shaft groove 7 is detachably fixed with elastic wear-resistant material.

[0026] The membrane shaft 6 is detachably fixedly connected to two inner pins 3 symmetrical about the membrane roll 4. The two inner pins 3 can limit the two membrane rolls 4 to prevent the membrane rolls 4 from moving along the axis of the membrane shaft 6 when using the film coating.

[0027] The membrane shaft 6 is detachably fixedly connected to two outer pins 1 symmetrical about the shaft wheel 2. The outer pins 1 and the nearest inner pin 3 together limit the shaft wheel 2 to prevent the shaft wheel 2 from moving along the axis of the membrane shaft 6.

[0028] When the two rollers 2 are limited, the distance between the annular grooves inside the two rollers 2 is the same as the distance between the two membrane supports 5, which allows the two rollers 2 to be inserted into the two shaft grooves 7, and the rollers 2 are limited in the shaft grooves 7 by the outer diameter portion of the two rollers 2, thus preventing the rollers 2 from moving along the axial direction of the membrane shaft 6.

[0029] In use, when loading or unloading the film roll 4 on either side, the film shaft 6 and the roller 2 on that side are removed from the corresponding shaft groove 7. At this time, the film shaft 6 and the roller 2 on the other side are slightly tilted in the shaft groove 7 on the other side, and are still limited and fixed by the film support 5 on the other side, which restricts the movement of the film shaft 6 along the axis of the film shaft 6. At this time, the inner pin 3 and the outer pin 1 on the loading and unloading side are removed. At this time, the roller 2 is no longer limited by the inner pin 3 and the outer pin 1. The roller 2 is taken out, and then the film roll 4 is pulled out or inserted into the film shaft 6. At this time, the film shaft 6 acts as a slide rail. After loading and unloading, the outer pin 1, roller 2 and inner pin 3 on the loading and unloading side are reinstalled, and the roller 2 and the film shaft 6 on the loading and unloading side are put back into the shaft groove 7 to complete the loading and unloading work. In this way, the loading and unloading of the film roll 4 can be completed by one person.

[0030] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
