[0016] The beneficial effects of the present invention are:

[0017] The frame of the present invention can provide a platform for placing silkworm rearing containers for silkworm rearing, and can also perform regular powdering and disinfection on the silkworm rearing containers. The powdering and disinfection efficiency is high, and the efficiency of the powdering and disinfection is greatly improved.

[0018] The hanging wheel mechanism of the present invention cooperates with the hanging rail to facilitate the movement of the hanging plate and the powder spreading mechanism. The hanging rope traction mechanism can pull and drive the hanging plate to slide, thereby cooperating with the hanging wheel mechanism to move the hanging plate and the powder spreading mechanism in a directional and fixed distance, and move the hanging plate and the powder spreading mechanism above the disinfection powder spreading area.

For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all inventions and creations utilizing the concepts of the present invention are protected.

[0044] like Figure 1 、 2 As shown in Figure 3, a dry powder disinfection spreading machine that can be used for silkworm breeding includes a frame 1, on which two parallel hanging rails 2 are provided, on which four hanging wheel mechanisms 3 are installed, and below which four hanging wheel mechanisms 3 are connected hanging plates 4, on which powder spreading mechanisms 6 are provided, and at the bottom of which powder blocking mechanisms 7 are provided; the frame 1 is also provided with a rope traction mechanism 5 that drives the hanging plates 4 to move. Figure 1 、 2 3. The frame 1 includes six vertical beams and four horizontal support plates. The six vertical beams and the four horizontal support plates are welded and fixed to form the frame 1. The four horizontal support plates are respectively provided with a powder spreading mechanism and a silkworm breeding container. By increasing the number of vertical beams and extending the length of the four horizontal support plates, the needs of silkworm breeding in actual production can be met.

[0045] The rope traction mechanism 5 includes a tensioning pulley 53, a reversing pulley 54, a traction pulley 57, a traction motor 56, a wire lock 51, two positioning pulleys 52, and a wire rope 55 connecting the positioning pulley 52, tensioning pulley 53, reversing pulley 54, and traction pulley 57. One end of the wire lock 51 is fixedly connected to the wire rope 55, and the other end is fixedly connected to the hanging plate 4. The traction pulley 57 is fixed to the output shaft of the traction motor 56. The positioning pulley 52, reversing pulley 54, and traction pulley 57 are located on the same straight line. The positioning pulley 52, tensioning pulley 53, reversing pulley 54, and traction pulley 57 are fixed to the frame 1 via a T-shaped shaft. The positioning pulley 52, tensioning pulley 53, reversing pulley 54, and traction pulley 57 are all provided with an annular groove that cooperates with the wire rope 55. The cross-section of the annular groove is semicircular. The traction motor 56 rotates, driving the wire rope 55 to move via the traction wheel 57, thereby driving the wire lock 51 to move via the wire rope 55, and the wire lock 51 drives the hanging plate 4 to move, thereby enabling the rope traction mechanism 5 to drive the hanging plate 4 and the powder spreading mechanism 6 to move, thereby performing the powder spreading disinfection operation. The tensioning wheel 53 is used to tension the wire rope 55. Two positioning wheels 52, a reversing wheel 54, and a traction wheel 57 transmit and guide the closed wire rope 55. A tensioning wheel mounting rod is also provided on the frame 1. The tensioning wheel mounting rod is provided with a strip hole for mounting a T-shaped shaft. An I-shaped slider is provided in the strip hole. The tensioning wheel mounting rod is provided with a fastening screw for locking the I-shaped slider, thereby conveniently fixing the position of the T-shaped shaft and the tensioning wheel 53, further tensioning the wire rope 55.

[0046] like Figure 15 As shown, the upper end of the wire lock buckle 51 is set in a U-shaped clamping mouth. Both ends of the U-shaped clamping mouth are provided with through holes. The U-shaped clamping mouth clamps and fixes the wire rope 55 through the bolt member 58. The U-shaped clamping mouth cooperates with the bolt member 58 to quickly clamp and tighten the wire rope 55, clamping firmly and having a simple structure. The clamping side of the U-shaped clamping mouth is also provided with an arc-shaped groove that cooperates with the wire rope 55. The contact area between the arc-shaped groove and the bolt member 58 is large, so the U-shaped clamping mouth can better clamp and fix the wire rope 55, making the clamping and fixation more stable. The lower end of the wire lock buckle 51 is welded and fixed to the hanging plate 4. The upper end of the wire lock buckle 51 is clamped and fixed to the wire rope 55, thereby facilitating the control of the movement of the wire rope 55 and driving the movement of the hanging plate 4 and the powder spreading mechanism 6.

[0047] like Figure 4 、 5 As shown in Figure 6, the hanging wheel mechanism 3 includes a mounting block 32, a hanging plate bolt 33 and a movable wheel 31. The movable wheel 31 is mounted on both sides of the mounting block 32. The mounting block 32 is provided with a vertical through hole for mounting the hanging plate bolt 33. The hanging plate bolt 33 is mounted in the vertical through hole. The bottom of the hanging plate bolt 33 is fixedly connected to the hanging plate 4 through a nut. The hanging plate 4 is provided with a mounting hole that matches the hanging plate bolt 33. The mounting block 32 facilitates the installation and fixation of the movable wheel 31 and the fixing of the hanging plate bolt 33. The cross section of the hanging rail 2 is an inverted concave shape, and the bottom of the hanging rail 2 is provided with a strip-shaped opening for mounting the hanging wheel mechanism 3, as shown in Figure 6. Figure 6 The four movable wheels 31 are located in the guide grooves on both sides of the hanging rail 2. The movable wheels 31 cooperate with the hanging rail 2 to make the hanging plate 4 move more smoothly.

[0048] like Figure 7 、 8As shown in Figures 9 and 10, the powder spreading mechanism 6 includes a powder box 61, which is in the shape of a Reuiluo triangle. A plurality of upper powder spreading holes 68 are provided at the bottom of the powder box 61. A powder box bracket 62 is provided on the powder box 61. The powder box bracket 62 is in the shape of a herringbone, and the herringbone end of the powder box bracket 62 is fixed to the inner corner of the powder box 61. A rotating shaft 63 is fixed to the powder box bracket 62. A limiting portion 64 is provided on the rotating shaft 63. The limiting portion 64 is connected to a connecting portion 65. The connecting portion 65 is connected to a transmission shaft 66, and the transmission shaft 66 is connected to a powder spreading motor 67. The cross-section of the rotating shaft 63 is in the shape of a Reuiluo triangle. The limiting portion 64 is a circular protrusion. The circular protrusion can be used to mount the powder box 61 on the hanging plate 4. The hanging plate 4 is provided with a shaft hole 41 that mates with the shaft 63. The shaft hole 41 is a square hole that mates with the shaft 63, and the diameter of the stopper 64 is greater than the diagonal length of the shaft hole 41. When the shaft 63 rotates within the shaft hole 41, it generates a certain amount of vibration. The powder-spreading motor 67 has three functions: 1. It drives the powder-spreading box 61 to rotate; 2. It utilizes the vibration generated by the rotation of the shaft 63 within the shaft hole 41 to vibrate and spread powder; and 3. It utilizes the centrifugal force of the powder-spreading box 61 in conjunction with the powder-blocking mechanism 7 to switch between powder-blocking and powder-spreading operations.

[0049] The powder blocking mechanism 7 includes a powder blocking plate 71 and a plurality of return springs 73. The powder blocking plate 71 is provided with a lower powder sprinkling hole 72 that matches the upper powder sprinkling hole 68. The powder blocking plate 71 and the powder sprinkling box 61 are provided with spring mounting posts 74 for mounting the return springs 73. The powder blocking plate 71 and the powder sprinkling box 61 are connected by the plurality of return springs 73. In normal state, the powder blocking mechanism 7 is in contact with the bottom of the powder sprinkling box 61 under the action of the return springs 73. At this time, the upper powder sprinkling hole 68 and the lower powder sprinkling hole 72 are staggered, as shown in FIG. Figure 11 and 12 When the powder-spreading motor 67 drives the powder-spreading box 61 to rotate through the transmission flexible shaft 66, under the action of centrifugal force, the powder-blocking plate 71 rotates relative to the powder-spreading box 61, and the return spring 73 is stretched. At this time, the lower powder-spreading hole 72 on the powder-spreading plate 71 rotates a certain angle and communicates with the upper powder-spreading hole 68 on the powder-spreading box 61. The disinfectant powder in the powder-spreading box 61 is sprinkled from the upper powder-spreading hole 68 and the lower powder-spreading hole 72. Since the rotating shaft 63 and the powder-spreading box 61 are both in the shape of a Leroy triangle, the powder-spreading box 61 sprinkles a square powder-spreading disinfection area. By cooperating with the powder-spreading box 61 to drive the hanging plate 4 to move, the powder-spreading disinfection operation in the moving rectangular area is achieved. Figure 13 ;like Figure 14 , the square disinfection area sprinkled by the powder box 61.

[0050] A hemispherical protrusion is provided at the geometric center of the upper end surface of the powder shield 71, and a hemispherical groove is provided at the bottom of the powder box 61 to cooperate with the hemispherical protrusion. The powder shield 71 can rotate in the hemispherical groove via the hemispherical protrusion. The powder shield 71 and the powder box 61 can also be rotatably connected by a rotating shaft. In this way, the powder shield 71 is fixed to the bottom of the powder box 61 via the rotating shaft, and the powder shield 71 can rotate relative to the powder box 61 via the rotating shaft.

[0051] like Figure 11 、 12 As shown in Figures 13 and 14, the powder box 61 and the rotating shaft 63 are both in the shape of a Reuleaux triangle, and the rotating shaft hole 41 is a square hole. When the rotating shaft 63 rotates in the rotating shaft hole 41, it will generate some vibration. The movement characteristics of the Reuleaux triangle are similar to the hole-opening mechanism of opening a square hole. The number of the lower powder holes 72 and the upper powder holes 68 is the same, and the lower powder holes 72 and the upper powder holes 68 are staggered at a certain angle, preferably in the range of 2°-15°. When the reset spring 73 is in normal state, the reset spring 73 makes the powder baffle 71 fit with the powder box 61, and the upper powder holes 68 are staggered with the lower powder holes 72. When the reset spring 73 is stretched to the maximum stroke, the powder baffle 71 rotates relative to the powder box 61, and the upper powder holes 68 are connected to the lower powder holes 72.
