When in use, the bottom frame 3 is horizontally arranged at the lower side of the existing net-covering device; the slide rail 41 is installed on the upper side of the bottom frame 3 and extends forward and backward along one side of the bottom frame 3, wherein: Figure 1 The front, back, left and right sides of the mesh cutting and separation device are indicated in the figure; the slider 42 can move forward and backward under the left and right of the power component 43, wherein the power component 43 can adopt an electric push rod, or other forms, which can be adopted according to actual needs; the thermal fuse 53 becomes hot after being energized, and can cut off the mesh after contacting the mesh; the threaded member 54 can adopt a bolt, and the threaded member 54 extends in the left and right directions. After the thermal fuse 53 is loose, the threaded member 54 is manually rotated to increase the distance between the adjustment blocks 52 at both ends of the thermal fuse 53, so that the thermal fuse 53 can be tightened again; in the present application, the cutting and separation mechanism 5 can be regarded as an integrated module, which has been pre-assembled in the factory, that is, the thermal fuse 53 has been pre-tensioned and installed. When replacing the thermal fuse 53, the separation rod assembly 51 is directly removed from the slider 42, and then the entire separation rod assembly 51 is replaced to complete the replacement of the thermal fuse 53. There is no need to adjust the thermal fuse 53, which improves the replacement efficiency of the thermal fuse 53.

[0030] When cutting the mesh sleeve, the thermal fuse 53 and the power assembly 43 are energized, the temperature of the thermal fuse 53 increases, and the power assembly 43 drives the slider 42 to move forward along the slide rail 41. The slider 42 drives the cutting and separation mechanism 5 to move forward synchronously.

[0031] As an implementation method, there are two slide rails 41, which are installed on the left and right sides of the bottom frame 3. A slider 42 is slidably connected to each slide rail 41. The separation rod assembly 51 is vertically arranged between the slide rails 41, and both ends of the separation rod assembly 51 are detachably connected to the slider 42.

[0032] Through the above arrangement, both ends of the separation rod assembly 51 can be supported by the slider 42 , thereby increasing the stability of the movement of the separation rod assembly 51 .

[0034] Through the above arrangement, the thermal fuse 53 is disposed on the front side of the release lever 511 through the adjustment block 52 and the mounting seat 512 .

[0035] In the present application, the cross section of the separation rod 511 is substantially elliptical with the long axis extending in the front-to-back direction, so as to prevent the separation rod 511 from damaging the mesh sleeve when cutting the mesh sleeve for the second time.

The second connecting block 521 is slidably connected in the second mounting groove 9, and the threaded member 54 is threadedly connected to the second connecting block 521.

[0040] Through the above arrangement, the second connecting block 521 and the second mounting groove 9 play a guiding role, and the adjusting block 52 is slidably connected to the mounting seat 512 through the second connecting block 521 and the second mounting groove 9 .

[0041] In the present application, the second mounting groove 9 is trapezoidal, and the width of the second mounting groove 9 gradually decreases from the groove bottom to the groove mouth, so that the adjustment block 52 can only move left and right along the mounting seat 512.

The fruit and vegetable detection device 10 and the motor 434 are both connected to the controller, and the controller can control the operation of the motor 434 according to the signal of the fruit and vegetable detection device 10.

[0046] Through the above arrangement, the degree of automation of the mesh sleeve cutting and separating device can be increased.

[0047] In the present application, the fruit and vegetable detection device 10 may use a through-beam sensor. When the fruits and vegetables pass upward through the bottom frame 3, they may be sensed by the fruit and vegetable detection device 10, and the controller controls the motor 434 to run, and the cutting and separation mechanism 5 starts to move.

[0048] As an implementation method, the mesh cutting and separation device also includes a displacement detection device, which includes a first sensor 11 and a second sensor 12.
