DETAILED DESCRIPTION

[0023] In order to better understand the utility model, the content of the utility model will be further clarified below by combining with the embodiments, but the protection content of the utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0024] As Figure 1 , 2As shown in Figure 3, a corn cob cooking device includes a cooking tank 101 with an open top. The bottom of the cooking tank 101 is provided with a support leg 102 and a discharge pipe 103. A control valve 104 is installed on the discharge pipe 103. A top cover 105 is detachably installed on the top of the cooking tank 101. An electric heating device is installed inside the bottom wall of the cooking tank 101. A feeding hopper 106 is installed on the top cover 105. A U-shaped fixing frame 107 is vertically installed on the top cover 105. A telescopic push rod 108 with an output shaft passing through the top of the fixing frame 107 is vertically installed on the fixing frame 107. A fixing plate 109 is installed at the lower end of the output shaft of the telescopic push rod 108. A drive motor 110 is installed at the bottom of the fixing plate 109. A drive motor 110 with an output shaft passing through the bottom of the drive motor 110 is installed at the lower end of the output shaft of the drive motor 110. The top cover 105 has a stirring shaft 111. Stirring blades 112 are mounted on the side of the stirring shaft 111. An L-shaped scraper 113, adapted to the inner wall of the cooking tank 101, is slidably mounted on one side of the stirring blades 112. The length of the horizontal portion of the scraper 113 is greater than the sum of the radius of the cooking tank 101 and the thickness of the vertical portion of the scraper 113. An adjusting screw 114 is horizontally mounted on the upper end of the stirring shaft 111. The vertical portion of the scraper 113 is rotatably connected to the adjusting screw 114. A connecting sleeve 115 is mounted on the scraper 113 and slidably connected to the stirring blades 112. A limiting bolt 116 is also mounted on the connecting sleeve 115, which abuts against the outer wall of the stirring blades 112 to fix the connection between the connecting sleeve 115 and the stirring blades 112. The top of the horizontal portion of the scraper 113 abuts against the bottom of the stirring shaft 111. This effectively prevents deformation of the horizontal portion of the scraper 113, allowing the horizontal portion of the scraper 113 to continuously and effectively scrape and clean the material adhering to the bottom inner wall of the cooking tank 101. The output shaft of the drive motor 110 is connected to the stirring shaft 111 via a coupling 121.

[0025] like Figure 3 As shown, the outer end of the adjusting screw 114 is also provided with a handle 117, and the vertical part of the scraper 113 is provided with a bearing 118. The outer ring of the bearing 118 is connected to the vertical part of the scraper 113, and the inner ring of the bearing 118 is fixedly connected to the adjusting screw 114.

[0026] like Figure 3 As shown, the limiting bolt 116 is a hand-tightening bolt. A temperature controller 119 electrically connected to the electric heating device is also installed on the outer wall of the cooking tank 101, and a temperature sensor electrically connected to the temperature controller 119 is installed on the side wall of the cooking tank 101.

[0027] like Figure 1 , 4 As shown, the top cover 105 is snapped and fixed to the cooking tank 101. The top cover 105 is also provided with connecting bolts 120 for screwing and fixing the cooking tank 101. The cooking tank 101 is provided with threaded connection holes that are compatible with hand-tightening bolts.

[0028] Workers can add a certain amount of corn cob scraps and dilute sulfuric acid into the cooking tank 101 through the feed hopper 106. The acid content of the corn cobs after mixing with the acid is 2%. Then, the electric heating device can be started to cook the mixture of corn cobs and acid. The required heating temperature is set by the temperature controller 119. The temperature controller 119 monitors the temperature inside the tank through the temperature sensor and controls the start and stop of the electric heating device to maintain the set temperature range. At the same time, the drive motor 110 is started, so that the stirring shaft 111 and stirring blades 112 can stir the mixture of corn cobs and acid. The scraper 113 can scrape and clean the corn cobs adhering to the bottom and side inner wall of the cooking tank 101 to avoid affecting the cooking effect. The telescopic push rod 108 can drive the stirring shaft 111, stirring blades 112 and scraper 113 to move vertically, thereby fully stirring the mixture of corn cobs and acid inside the cooking tank 101, and further improving the cooking effect.

[0029] After complete cooking, the control valve 104 can be opened to discharge the cooked corn cob material through the discharge pipe 103.

[0030] After a period of time, when the scraper 113 wears out, the telescopic push rod 108 can drive the stirring shaft 111, stirring blades 112 and scraper 113 to move vertically downward, thereby compensating for the vertical wear of the scraper 113, so that the bottom of the scraper 113 can continuously and effectively scrape and clean the material adhering to the inner wall of the bottom of the mixing tank.

[0031] First, loosen the connecting bolts 120 to release the fixation between the top cover 105 and the cooking tank 101. Then, move the top cover 105, stirring shaft 111, stirring blade 112, and scraper 113 upwards together. Next, loosen the limiting bolts 116 to release the fixation between the limiting bolts 116 and the connecting sleeve 115 and the stirring blade 112. Then, adjust the adjusting screw 114 by turning the handle 117, and adjust the scraper 113 laterally with the cooperation of the bearing 118. Finally, retighten the screw. Tightening the limiting bolt 116 compensates for the wear on the side of the scraper 113, allowing the side of the scraper 113 to continue effectively scraping and cleaning the material adhering to the inner wall of the mixing tank side. The connecting sleeve 115 enables the scraper 113 to slide and connect with the stirring blade 112. The limiting bolt 116 limits and fixes the connection between the connecting sleeve 115 and the stirring blade 112, thereby preventing the scraper 113 from undergoing lateral deformation relative to the stirring blade 112 and affecting the scraping effect.

[0032] According to another embodiment of the present invention, such as Figure 4 , 5As shown, the side end of the fixed frame 107 is also provided with a guide groove 201, and the side end of the fixed plate 109 is also provided with a guide slider 202 that is slidably connected to the guide groove 201. The slot of the guide groove 201 and the cross-section of the guide slider 202 are both T-shaped. During and after the vertical adjustment of the telescopic push rod 108 driving the fixed plate 109 and the drive motor 110, the vertical sliding cooperation of the guide groove 201 and the guide slider 202 can keep the fixed plate 109 and the drive motor 110 stable, and can prevent the telescopic push rod 108 from deforming and being damaged due to non-vertical displacement.

[0033] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a handle 203 is also provided on the top cover 105. Workers can easily move the top cover 105 using the handle 203, and easily achieve or disengage the top cover 105 from the cooking tank 101.

[0034] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a transparent observation window 204 is also provided on the side of the cooking tank 101. Workers can conveniently observe the inside of the cooking tank 101 through the transparent observation window 204 without opening the top cover 105.

[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
