[0023] Embodiment: A rice loading and lifting device comprises a base 1, a gate-shaped bracket 2 vertically fixed on the base 1, a pair of lifting seats 3 lifted and lowered on the gate-shaped bracket 2, a lifting mechanism 4 that drives the two lifting seats 3 to lift and lower synchronously, a pair of rotating rods 5 respectively rotatably connected to the two lifting seats 3, a lifting platform 6 with the two rotating rods 5 fixed on both sides, a square rice loading bucket 7 placed on the lifting platform 6, a locking mechanism 8 for positioning and fixing the rice loading bucket 7 on the lifting platform 6, a pair of guide plates 9 vertically fixed on the base 1 and located on both sides of the lifting platform 6, a sliding rod 10 fixed on both sides of the lifting platform 6, and a groove 11 opened on one side of the guide plate 9 for the sliding rod 10 to slide. The guide plate 9 is located parallel to one side of the gate-shaped bracket 2, and the heads of the guide plate 9 and the groove 11 are bent, and the bending direction is away from the gate-shaped bracket 2. The sliding rod 10 and the rotating rod 5 are parallel to each other, and when the lifting platform 6 is at the bottom of the gate-shaped bracket 2, the sliding rod 10 is located above the rotating rod 5.

[0024] Furthermore, the lifting mechanism 4 includes a rotating shaft 1 41 rotatably mounted on one side of the gate-shaped bracket 2, a pair of sprockets 1 42 fixedly mounted on the rotating shaft 1 41, a pair of sprockets 2 43 rotatably mounted on the gate-shaped bracket 2, two chains 44 respectively mounted on the two pairs of sprockets 1 42 and sprockets 2 43, and a worm gear reduction motor 45 for driving the rotation of the first sprocket 43. The two lifting platforms 3 are respectively fixed on the same side of the two chains 44 in the same direction of movement. The sprockets 1 42 and sprockets 2 43 are respectively located near the upper and lower ends of the gate-shaped bracket 2. The worm gear reduction motor 45 is fixed to the gate-shaped bracket 2, and its output end is rotatably connected to the first sprocket 2 43. By adopting the above-mentioned lifting mechanism 4, not only can the two lifting platforms 3 be driven to rise and fall synchronously, but the worm gear reduction motor 45 also has a stable power output, a large output torque, and a self-locking function, thereby effectively ensuring the lifting safety of the lifting platform 6 and the rice loading bucket 7.

[0025] Furthermore, the lifting platform 6 includes a horizontal platform 61 and a U-shaped guardrail 62 vertically fixed to the platform 61. The three outer side surfaces of the U-shaped guardrail 62 are flush with the three adjacent side surfaces of the platform 61, and the opening direction of the U-shaped guardrail 62 is opposite to the bending direction of the head of the guide plate 9. Two pairs of sliding rods 10 and the rotating rod 5 are respectively fixed to the two opposite outer sides of the U-shaped guardrail 62. The three inner side surfaces of the U-shaped guardrail 62 are in contact with the three adjacent side surfaces of the rice loading bucket 7. By adopting the above-mentioned lifting platform 6 structure, it is convenient for workers to quickly remove or put the rice loading bucket 7.

[0026] Furthermore, the locking mechanism 8 includes a pair of positioning plates 81 fixed on an outer side of the rice feeding barrel 7, a pair of positioning holes 82 opened on the side wall of the U-shaped fence 62 and for the two positioning plates 81 to penetrate, a rotating shaft 83 rotatably set on the outer side of the U-shaped fence 62, a rotating component 84 for controlling the rotation of the rotating shaft 83, a pair of screws 85 respectively fixedly connected to the two ends of the rotating shaft 83, a pair of square sleeves 86 fixed on the outer side of the U-shaped fence 62 and respectively surrounding the two screws 85, a pair of square slides 87 respectively slidably inserted into the two square sleeves 86, a threaded hole 88 opened at one end of the square slide 87 and threadedly connected to the screw 85, and a locking hole 89 opened on the positioning plate 81 and for the other end of the square slide 87 to be inserted. The positioning hole 82 is located on the middle side wall of the U-shaped fence 62, and the rotating shaft 83, the screw 85, the square sleeve 86 and the square slide 87 are horizontally located between the two positioning holes 82.

[0027] Furthermore, the rotating assembly 84 includes a bevel gear 1 841 fixedly mounted on the rotating shaft 2 83, a rotating shaft 3 842 rotatably mounted on the outer side of the U-shaped fence 62 and perpendicular to the rotating shaft 2 83, a bevel gear 2 843 fixedly connected to one end of the rotating shaft 3 842 and meshing with the bevel gear 1 841, and a hand crank 844 fixedly connected to the other end of the rotating shaft 3 842. By using this rotating assembly 84, it is convenient for the operator to manually control the rotation of the rotating shaft 2 83, and then cooperate with other components of the locking mechanism 8 to quickly achieve the locking effect of the rice feeding bucket 7.

[0028] Furthermore, a U-shaped support plate 63 is fixedly mounted on the outer side of the U-shaped fence 62. The second rotating shaft 83 and the first bevel gear 841 are located inside the U-shaped support plate 63, and the two ends of the second rotating shaft 83 rotate through the two opposite side walls of the U-shaped support plate 63. The second bevel gear 843 and the hand crank 844 are located inside and outside the U-shaped support plate 63, respectively. The third rotating shaft 842 rotates through the middle side wall of the U-shaped support plate 63, and the two ends are fixedly connected to the second bevel gear 843 and the hand crank 844, respectively. Two square sleeves 86 are respectively fixed to the two outer sides of the U-shaped support plate 63. The use of the above-mentioned U-shaped support plate 63 not only provides support for the rotation of the second rotating shaft 83 and the second rotating shaft 83 and provides a fixed position for the square sleeves 86, but also prevents manual rotation and cranking from contacting the movable bevel gear 1 841 and the second bevel gear 843, which could cause pinching injuries.

[0029] Furthermore, the gate-shaped bracket 2 and the guide plate 9 are fixedly connected to a plurality of horizontal connecting plates 21 on opposite sides thereof. A second sprocket 43 is rotatably connected to the side of a connecting plate 21 facing the lifting platform 6. A worm gear reduction motor 45 is fixed to the side of a connecting plate 21 facing away from the lifting platform 6, and the output end rotates through the connecting plate 21 and is fixedly connected to the second sprocket 43 on the other side thereof. The use of the above-mentioned connecting plates 21 not only further improves the structural stability of the gate-shaped bracket 2 and the guide plate 9, but also provides rotational support for the second sprocket 43 and a fixed mounting position for the worm gear reduction motor 45.

[0030] Furthermore, four flexibly rolling universal casters 71 are installed at the bottom of the rice loading bucket 7, and a handrail 72 is fixedly provided on one side of the rice loading bucket 7 close to the opening of the U-shaped railing 62, which can further facilitate the staff to take the rice loading bucket 7 out of the lifting platform 6.

[0031] Furthermore, a slope 1a is fixedly provided at one end of the base 1 for the universal caster 71 at the bottom of the rice loading bucket 7 to roll into the top of the platform 61, which can cooperate with the universal caster 71 to safely remove the rice loading bucket 7.

[0032] Furthermore, a pair of diagonal braces 1b are fixedly connected between the side of the door-shaped bracket 2 facing away from the guide plate 9 and the base 1, and a pair of diagonal braces 1c are fixedly connected between the side of the guide plate 9 facing away from the door-shaped bracket 2 and the base 1, which can further enhance the structural strength of the door-shaped bracket 2 and the guide plate 9, thereby ensuring the service life of the equipment.

[0033] The working principle of this embodiment is as follows:

[0034] When it is necessary to lift the rice, first put the rice into the rice loading bucket 7. After it is full, manually push it above the platform 61 and ensure that the positioning plate 81 on one side of the rice loading bucket 7 passes through the positioning hole 82 of the U-shaped fence 62; then, manually turn the hand crank 844 to rotate the rotating shaft 3 842 and the bevel gear 2 843. Since the bevel gear 2 843 and the bevel gear 1 841 are engaged with each other, and the bevel gear 1 841 is fixed on the rotating shaft 2 83, the bevel gear 2 843 rotates. The wheel 1 841 will drive the rotating shaft 2 83 and the screw 85 to rotate. Since the threaded rods are respectively threadedly connected to the threaded holes 88 of the two square sliding posts 87, and the square sliding posts 87 are slidably inserted into the square sleeve 86 around the screw 85, when the screw 85 rotates, the square sliding post 87 will slide relative to the square sleeve 86, and the end extending out of the square sleeve 86 will be inserted into the locking hole 89 on the positioning plate 81, thereby positioning and fixing the rice feeding bucket 7 above the platform 61 and in the middle of the U-shaped fence 62.

[0035] Then, the worm gear reduction motor 45 is started to drive the sprocket 2 43 to rotate, so that the sprocket 2 43 drives the chain 44 to move, and the chain 44 drives the sprocket 1 42 to rotate. Since the two sprockets 1 42 are fixed on the same rotating shaft 1 41, the two chains 44 will synchronously drive the two lifting seats 3 to move upward; then, the lifting seat 3 will drive the U-shaped fence 62 and the platform 61 to move upward through the rotating rod 5, and the sliding columns on both sides of the U-shaped fence 62 will move along the guide rail under the lifting of the U-shaped fence 62. The groove 11 of the guide plate 9 slides; finally, when the slide slides to the bent part of the head of the guide plate 9, since the rotating rod 5 is still rising with the lifting seat 3, and the slide gradually changes from vertical movement to horizontal movement, the U-shaped fence 62 will automatically flip to the direction of the bending direction of the head of the guide plate 9 under the movement of the slide and the rotating rod 5, and until the rotating rod 5 is lifted to the top of the slide, the rice loading bucket 7 in the middle of the U-shaped fence 62 will be in a tilting posture, and the rice inside it will be poured into the feed port of the processing equipment from a high place.
