DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides a fault detection device, including a detection platform 2 and a residual film recovery machine, the residual film recovery machine includes a conveying mechanism 101, a screen drum 102 and a collecting box 103, a plurality of rotating wheels 104 are installed on the residual film recovery machine, a lifting plate 105 is arranged on the front side of the conveying mechanism 101, a circular track is arranged on the outer side of the screen drum 102, a driving motor for driving the screen drum 102 is arranged on the residual film recovery machine, and also includes a first support assembly and a second support assembly arranged on the detection platform 2 for supporting the screen drum 102, the first support assembly includes a round base 301 arranged on the upper side of the detection platform 2, a plurality of support frames 302 are fixed on the round base 301, and a support wheel 303 for supporting against the circular track is installed on the support frame 302, an installation cavity 4 is opened inside the detection platform 2, the second support assembly is located inside the installation cavity 4, and the installation cavity 4 is provided with a detection assembly for detecting screening faults of the screen drum 102;

[0019] It should be noted here that: during the processing of the residual film recovery machine, when some larger soil blocks cause the sieve holes of the screen drum 102 to be blocked during the screening process, the circular base 301 of the bottom plate of the screen drum 102 is driven to move toward the inside of the installation cavity 4, and in the process of movement, the induction plate 601 is driven to move close to the proximity sensor 603. When the proximity sensor 603 recognizes the induction plate 601, information is transmitted through the proximity sensor 603 and the external alarm is activated to give an alarm, thereby giving a timely alarm for the screening failure of the screen drum 102.

[0020] The detection component includes a sensing plate 601 fixed to the lower end of the circular base 301, a circular frame 602 is arranged inside the installation cavity 4, a proximity sensor 603 for identifying the descending position of the sensing plate 601 is installed at the upper end of the circular frame 602, and the proximity sensor 603 is located below the sensing plate 601. An adjustment component for adjusting the detection position of the circular frame 602 and a guide component for guiding during the adjustment process are arranged on the detection platform 2. An alarm and a controller are installed on the detection platform 2, and the alarm is electrically connected to the proximity sensor 603 and the controller;

[0021] It should be noted here that: when some larger soil blocks cause the sieve holes of the sieve drum 102 to be blocked during the screening process, the screening efficiency of the sieve drum 102 is low and a large number of soil blocks transported by the conveying mechanism 101 are accumulated inside the sieve drum 102, further increasing the weight of the entire sieve drum 102. In the process of increasing weight of the sieve drum 102, under the action of gravity, the circular base 301 of the bottom plate of the sieve drum 102 moves toward the inside of the installation cavity 4. During the movement, the induction plate 601 is driven to move close to the proximity sensor 603. When the proximity sensor 603 recognizes the induction plate 601, information is transmitted through the proximity sensor 603 and the external alarm is activated to give an alarm, thereby giving a timely alarm for the screening failure of the sieve drum 102.

[0022] There are multiple groups of second support components evenly distributed inside the installation cavity 4;

[0023] It should be noted here that: a plurality of sets of second support components facilitate more stable support.

[0024] The second supporting assembly includes a first sleeve 501 fixed inside the installation cavity 4, a first slide bar 502 is slidably connected to the first sleeve 501, one end of the first slide bar 502 is fixed to the round-shaped base 301, and a spring 503 is sleeved on the outer side of each first sleeve 501, and the two ends of the spring 503 are respectively against the round-shaped base 301 and the inner wall of the installation cavity 4;

[0025] It should be noted here that: the circular base 301 and the components on the circular base 301 are supported by the springs 503 , and the movement of the circular base 301 is guided by the first sleeves 501 and the first slide bars 502 .

[0026] The adjusting component includes a threaded tube 701 rotatably connected to the lower end of the detection platform 2, a threaded rod 702 is threadedly engaged with the threaded tube 701, one end of the threaded rod 702 is fixed to the circular frame 602, and a driving pin 703 is fixed to the other end of the threaded tube 701; the guiding component includes two groups of second sleeves 801 fixed inside the installation cavity 4, the two groups of second sleeves 801 are symmetrically arranged on both sides of the threaded tube 701, and the two groups of second sleeves 801 are slidably connected to the second slide rod 802, and one end of the second slide rod 802 is fixed to the lower end of the circular frame 602;

[0027] It should be noted here that: the threaded tube 701 is driven to rotate by the driving pin 703. During the rotation of the threaded tube 701, the mutually meshing transmission between the threaded tube 701 and the threaded rod 702 and the sliding guiding effect of the two sets of second sleeves 801 and the second sliding rod 802 enable the circular frame 602 to move inside the installation cavity 4 after being subjected to force.

[0028] Working principle: During the processing of the residual film recovery machine, the soil is scooped up by the soil lifting plate 105 and transported to the inside of the screen drum 102 through the conveying mechanism 101 for screening. During the screening process, the screened soil blocks fall directly, and the residual film recovered after screening flows into the inside of the collection box 103 through the rotation of the screen drum 102 for collection. During the screening process of the screen drum 102, the support of the support wheels 303 on the multiple support frames 302 and the outer circular track of the screen drum 102 facilitates the screen drum 102 to perform the residual film screening operation more stably;

[0029] In the process of supporting and rotating the screen drum 102 for screening, when some larger soil blocks cause the screen holes of the screen drum 102 to be blocked during the screening process, the screening efficiency of the screen drum 102 is low and a large number of soil blocks transported by the conveying mechanism 101 are accumulated inside the screen drum 102, further increasing the weight of the entire screen drum 102. In the process of increasing weight of the screen drum 102, under the action of gravity, the circular base 301 of the bottom plate of the screen drum 102 moves toward the inside of the installation cavity 4, and in the process of movement, drives the induction plate 601 to move close to the proximity sensor 603. When the proximity sensor 603 recognizes the induction plate 601, information is transmitted through the proximity sensor 603 and the external alarm is activated to alarm, so as to give a timely alarm for the screening failure of the screen drum 102, so as to facilitate the operator to deal with the soil blocks blocking the screen drum 102, and further ensure the efficiency and quality of residual film recovery.

[0030] During the use of the detection component, the adjustment component and the guide component cooperate with each other to drive the circular frame 602 to move inside the installation cavity 4. The distance between the proximity sensor 603 and the sensing plate 601 on the circular frame 602 is adjusted through the movement of the circular frame 602. By adjusting the distance, the detection component can be used for detection and alarm with different sensitivities.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
