DETAILED DESCRIPTION

[0026] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1-7 As shown, the present invention provides a technical solution: a rice dumpling cooking machine that is convenient for discharging, comprising a heating base 1, bottom angles 7 are fixedly installed at the four corners of the bottom of the heating base 1, and a heating coil 8 is embedded and installed at the bottom of the heating base 1. By providing the heating coil 8, an appropriate amount of clean water is injected into the cooking box 2, and after the mesh box 5 containing raw rice dumplings is fixed inside the cooking box 2, the heating coil 8 is controlled to be energized to start heating the cooking box 2, so that the clean water inside the cooking box 2 is quickly heated to cook the raw rice dumplings inside the mesh box 5;

[0028] A cooking box 2 is fixedly installed on the top of the heating base 1, and a drainage groove 201 is provided at the central position of the bottom of the cooking box 2. A drainage valve 202 is provided at the central position of the bottom of one side of the cooking box 2, and the drainage valve 202 is connected with the drainage groove 201. Due to the drainage groove 201 and the drainage valve 202, the liquid inside the cooking box 2 needs to be replaced after cooking. The drainage valve 202 is opened to concentrate the liquid inside the cooking box 2 inside the drainage groove 201. The liquid flows through the drainage groove 201 to the drainage valve 202, thereby discharging the liquid from the inside of the cooking box 2.

[0029] Two groups of fixing blocks 203 are fixedly installed at both ends of the top of both sides of the cooking box 2, and a rotating stud 204 is rotatably installed between the two groups of fixing blocks 203, and a fixing nut 205 is provided on the surface of the rotating stud 204. A top frame 3 is provided on the top of the cooking box 2, and a connecting card plate 301 is fixedly installed at both ends of both sides of the top frame 3, and a connecting card slot 302 is provided on one side of the connecting card plate 301, and the connecting card slot 302 corresponds to the position of the rotating stud 204. By providing the rotating stud 204 and the connecting card plate 301, after the top frame 3 is placed on the top of the cooking box 2 accordingly, so that the position of the connecting card plate 301 corresponds to the position of the rotating stud 204, the rotating stud 204 is controlled to rotate, so that the rotating stud 204 is clamped into the corresponding connecting card slot 302, and the fixing nut 205 is tightened to be close to the top of the connecting card plate 301, so that the rotating stud 204 is clamped and fixed inside the connecting card slot 302, so that the top frame 3 can be clamped and fixed on the top of the cooking box 2;

[0030] A mounting plate 303 is fixedly installed at the central position inside the top frame 3, and breathable cover plates 304 are symmetrically mounted on both sides of the mounting plate 303, and a clamping groove 305 is provided at the central position of the breathable cover plate 304 away from the mounting plate 303. Because of the breathable cover plate 304, after the top frame 3 is fixed to the top of the cooking box 2 and the breathable cover plate 304 is clamped and fixed to the top of the top frame 3, the heating coil 8 is started to heat the cooking box 2, and the steam generated by the heating is discharged from the air holes of the breathable cover plate 304, so as to prevent steam from accumulating inside the cooking box 2 when the cooking box 2 is continuously heated, resulting in an increase in the internal air pressure of the cooking box 2, causing the cooking box 2 to rupture or explode.

[0031] A rectangular groove 306 is respectively provided at the central position of the top of both sides of the top frame 3, and a limit plate 307 is slidably installed inside the two ends of the rectangular groove 306. A clamping rod 308 is fixedly installed on one side of the limit plate 307. A clamping spring 309 is provided on the surface of the clamping rod 308. Two groups of clamping rods 308 extend through the top frame 3 to the outside of the top frame 3 and are fixedly installed with a connecting plate 310. A connecting block 311 is fixedly installed at the central position of the surface of the connecting plate 310, and the connecting block 311 and the clamping spring 309 are fixedly installed on the surface of the clamping rod 308. The position of the card slot 305 corresponds to that of the card slot 305. A clamping spring 309 is provided. Under the rebound action of the clamping spring 309, the limit plate 307 is pressed against the inside of the top frame 3 away from the connecting plate 310, so that the clamping rod 308 can drive the connecting plate 310 to be close to the surface of the top frame 3, ensuring that the connecting block 311 can be inserted into the corresponding clamping card slot 305, and the breathable cover plate 304 is pressed and fixed on the top of the top frame 3, so as to prevent the breathable cover plate 304 from being lifted up and opened due to the increase in the internal air pressure of the cooking box 2.

[0032] Hooks 4 are fixedly installed at the four corners of the top frame 3. Due to the hooks 4, the crane is controlled to be suspended on the top of the top frame 3. The crane is connected to the four sets of hooks 4 by ropes, and the crane is controlled to shrink and move, so as to lift the top frame 3 away from the cooking box 2.

[0033] The bottom of the top frame 3 is located inside the cooking box 2 and is fixedly installed with a mesh box 5. A mounting block 501 is fixedly installed at the central position of the bottom of both sides of the mesh box 5. Mounting grooves 502 are symmetrically arranged inside the two ends of the mounting block 501. A second limiting plate 503 is slidably installed at one end of the mounting groove 502, and a moving rod 504 is fixedly installed on one side of the second limiting plate 503. A lever 505 and a fixed clamping column 506 are fixedly installed at one end of the moving rod 504 away from the second limiting plate 503, and there is a space between the lever 505 and the fixed clamping column 506. It passes through the mounting groove 502 at a right angle and extends to the outside of the mounting block 501. A fixing spring 507 is provided on the surface of the moving rod 504 located inside the mounting groove 502. By providing the fixing spring 507, the limiting plate 503 is pushed toward one end inside the mounting groove 502 under the rebound action of the fixing spring 507, so that the fixing clamping column 506 can be clamped into the fixing clamping groove 603 for movement, thereby clamping and fixing the fixing clamping plate 602 to the bottom of the mounting block 501, ensuring that the blanking plate 601 is closed at the bottom of the mesh box 5 and will not open at will.

[0034] The mounting plate 2 6 is fixedly installed at the central position of the bottom of the mesh box 5. The bottoms of both sides of the mounting plate 2 6 are symmetrically rotatably installed with blanking plates 601, and the central position of the blanking plate 601 away from the mounting plate 2 6 is fixedly installed with a fixed clamping plate 602, and the fixed clamping plate 602 is symmetrically provided with fixed card grooves 603 on both sides, and the fixed card grooves 603 correspond to the positions of the fixed clamping columns 506. Because the fixed card grooves 603 are provided, after the fixed clamping columns 506 pass through the fixed card grooves 603, the shifting rod 505 is released, and the fixed clamping columns 506 slide inside the fixed card grooves 603 under the rebound action of the fixed springs 507, so that the blanking plate 601 is clamped and fixed to the bottom of the mesh box 5.

[0035] A method for using a rice dumpling cooking machine that is convenient for discharging materials, the method comprising the following steps:

[0036] The two groups of levers 505 on one side of the mesh box 5 are pushed to approach each other, driving the moving rod 504 to move inside the installation slot 502, controlling the two groups of fixed clamping columns 506 to approach each other, causing the fixed spring 507 to be compressed and deformed inside the installation slot 502, rotating the blanking plate 601 to be close to the bottom of the mesh box 5, and after the fixed clamping column 506 passes through the fixed clamping slot 603, releasing the lever 505, and under the rebound effect of the fixed spring 507, the two ends of the limit plate 2 503 box mounting block 501 are lifted up, driving the fixed clamping column 506 to move toward both ends inside the fixed clamping slot 603, thereby clamping and fixing the blanking plate 601 to the bottom of the mesh box 5, and repeating the steps to clamp and fix the blanking plate 601 on the other side to the bottom of the mesh box 5;

[0037] Control the overhead crane to suspend the top frame 3 on the top of the cooking box 2, so that the mesh box 5 falls into the cooking box 2, until the top frame 3 is tightly attached to the top of the cooking box 2, the rotating stud 204 corresponds to the connecting card plate 301, loosen the fixing nut 205 on the surface of the rotating stud 204 to rotate the rotating stud 204 and insert it into the corresponding connecting card slot 302, tighten the fixing nut 205 on the surface of the rotating stud 204 to make it tightly attached to the top of the connecting card plate 301, repeat the steps to clamp and fix four groups of rotating studs 204 in the corresponding connecting card slots 302, so that the top frame 3 is clamped and fixed to the top of the cooking box 2;

[0038] Tighten and close the drain valve 202, open the breathable cover 304 and put an appropriate amount of raw rice dumplings into the mesh box 5, and at the same time inject an appropriate amount of clean water into the cooking box 2 until the clean water covers the raw rice dumplings, flip the breathable cover 304 to cover the top of the top frame 3, pull the connecting plate 310 to make the connecting block 311 away from the top frame 3, so that the breathable cover 304 horizontally covers the top of the top frame 3, ensure that the clamping groove 305 corresponds to the connecting block 311, and loosen the connecting plate. Under the rebound action of the compression spring 309, 310 presses the connecting plate 310 toward the top frame 3, so that the connecting block 311 is inserted into the corresponding compression slot 305, and the breathable cover plate 304 is clamped and fixed on the top of the top frame 3. The heating coil 8 is controlled to be energized to heat the cooking box 2, and the raw rice dumplings inside the mesh box 5 are cooked. At the same time, the steam generated by the heating inside the cooking box 2 is discharged from the air holes of the breathable cover plate 304, thereby balancing the air pressure inside and outside the cooking box 2.

A method for using a rice dumpling cooking machine that is convenient for discharging materials, according to any one of claims 1 to 6, characterized in that: The method of use comprises the following steps: The two groups of levers (505) on one side of the mesh box (5) are pushed to approach each other, driving the moving rod (504) to move inside the mounting groove (502), controlling the two groups of fixed clamping columns (506) to approach each other, causing the fixed spring (507) to be compressed and deformed inside the mounting groove (502), rotating the blanking plate (601) to be close to the bottom of the mesh box (5), and after the fixed clamping column (506) passes through the fixed clamping groove (603), releasing the lever (505) to lift up the two ends of the limit plate second (503) box mounting block (501) under the rebound action of the fixed spring (507), driving the fixed clamping column (506) to move toward both ends inside the fixed clamping groove (603), thereby clamping and fixing the blanking plate (601) to the bottom of the mesh box (5), and repeating the steps to clamp and fix the blanking plate (601) on the other side to the bottom of the mesh box (5); Control the overhead crane to suspend the top frame (3) on the top of the cooking box (2) so that the mesh box (5) falls into the cooking box (2) until the top frame (3) is tightly attached to the top of the cooking box (2), the rotating stud (204) is aligned with the connecting card plate (301), the fixing nut (205) on the surface of the rotating stud (204) is loosened to rotate the rotating stud (204) into the corresponding connecting card slot (302), and then the fixing nut (205) on the surface of the rotating stud (204) is tightened to fit tightly against the top of the connecting card plate (301), and the steps are repeated to clamp and fix four groups of rotating studs (204) in the corresponding connecting card slots (302), thereby clamping and fixing the top frame (3) on the top of the cooking box (2); Tighten and close the drain valve (202), open the breathable cover plate (304), put an appropriate amount of raw rice dumplings into the mesh box (5), and at the same time inject an appropriate amount of clean water into the cooking box (2) until the clean water covers the raw rice dumplings, flip the breathable cover plate (304) to cover the top of the top frame (3), pull the connecting plate (310) to make the connecting block (311) away from the top frame (3), so that the breathable cover plate (304) horizontally covers the top of the top frame (3), ensure that the pressing groove (305) corresponds to the connecting block (311), and loosen the connecting plate (310). Under the rebound effect of the compression spring (309), the connecting plate (310) is pressed toward the top frame (3), so that the connecting block (311) is inserted into the corresponding compression slot (305), and the breathable cover plate (304) is clamped and fixed on the top of the top frame (3). The heating coil (8) is controlled to be energized to heat the cooking box (2), so that the raw rice dumplings in the mesh box (5) are cooked. At the same time, the steam generated by the heating inside the cooking box (2) is discharged from the air holes of the breathable cover plate (304), thereby balancing the air pressure inside and outside the cooking box (2).
