[0002] In many industrial sectors such as ore processing and building material production, sand making is a crucial step, directly impacting the quality of subsequent products. Traditional sand making equipment has revealed numerous problems in practical applications. Taking a common sand making machine as an example, during the crushing process, ore easily splashes everywhere, posing a serious threat to the safety of operators, wasting ore, and creating a dirty and messy production environment. Furthermore, the crushing structure of traditional sand making machines is not optimal; the contact between the crushing rollers and the ore is insufficient, resulting in low crushing efficiency and making it difficult to meet the demands of large-scale production.

[0003] Furthermore, bearings, as critical components, directly affect the stability and lifespan of the equipment during operation. However, traditional sand making machines lack effective bearing temperature monitoring methods, making it impossible for operators to promptly understand the bearing's operating temperature. If a bearing malfunctions due to overheating, it often leads to equipment downtime for repairs, impacting production progress and increasing production costs. Therefore, developing a new type of roller press sand making machine is of significant practical importance. Utility Model Content

The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0025] Example 1: A roller crushing mill includes a double-toothed roller crusher 1, with a crushing zone protective cover 2 hinged to the right side of the top end face of the double-toothed roller crusher 1. A motor support base 102 is fixedly connected to the right side of the top surface of the base 101 of the double-toothed roller crusher 1. The bottoms of two motors 103 and one reducer 104 are bolted to the top surface of the motor support base 102. The output shafts of the motors 103 are connected to the power input shaft of the reducer 104 via couplings. A crushing trough 105 is fixed to the left side of the upper surface of the base 101. Two through holes for toothed rollers 106 to pass through are opened on both its left and right side walls. The two toothed rollers 106 are rotatably disposed within the inner cavity of the crushing trough 105, and the sections located outside the crushing trough 105 are respectively adapted to two bearings 107 installed on the left and right end faces of the crushing trough 105. The power input end of the toothed rollers 106 is connected to the power output shaft of the reducer 104. A heat-conducting copper plate 108 is fixedly connected to the outer surface of the bearing 107. A contact temperature sensor 109 is fixedly connected to the end face of the heat-conducting copper plate 108 away from the bearing 107. The temperature data transmission terminals of the contact temperature sensor 109 are connected to the control box via wires, and the working temperature data of the bearing 107 is displayed on the display panel on the control box. Two hinges 202 are fixedly connected to the right side of the transparent cover 201 of the crushing zone protective cover 2. The other end of the hinge 202 is fixedly connected to the top of the right side wall of the crushing trough 105. Several arc-shaped steel bars 204 are fixedly connected to the top side wall of the inner cavity of the transparent cover 201. A steel plate 203 is fixed to the lower end face of the arc-shaped steel bars 204. The arc-shaped steel bars 204 provide downward pressure elasticity for the steel plate 203, so that the steel plate 203 squeezes the ore into contact with the crushing zone between the toothed roller 106. During operation, the motor 103 is started, and the geared roller 106 is driven to rotate through the reducer 104, so that the ore is put into the crushing trough 105. The crushing zone protective cover 2 prevents the ore from splashing. At the same time, the contact temperature sensor 109 monitors the temperature of the bearing 107 in real time and displays it on the control box.

[0026] Example 2: A roller crusher includes a double-toothed roller crusher 1 and a crushing zone protective cover 2 hinged to the right side of its top end face. In the double-toothed roller crusher 1, a motor support base 102 is provided on the right side of the upper surface of the base 101. Two motors 103 and a reducer 104 are fixed on the motor support base 102. The output shaft of the motor 103 is connected to the power input shaft of the reducer 104 via a coupling. The crushing trough 105 is installed on the left side of the upper surface of the base 101. Two bearings 107 are installed on each of its left and right end faces. Two toothed rollers 106 pass through the through holes in the side wall of the crushing trough 105 and are adapted to the bearings 107. The power input end of the toothed rollers 106 is connected to the power output shaft of the reducer 104. A heat-conducting copper plate 108 is fixed on the outside of the bearings 107. A contact temperature sensor 109 is fixed on the other side of the heat-conducting copper plate 108. Its temperature data transmission end is connected to the control box to display the operating temperature of the bearings 107. The transparent cover 201 of the crushing zone protective cover 2 is connected to the top of the right side wall of the crushing trough 105 via two hinges 202 on the right side. Several arc-shaped steel bars 204 are located on the top side wall of the inner cavity of the transparent cover 201. A steel plate 203 is fixed to the lower end of each arc-shaped steel bar 204. The arc-shaped steel bars 204 provide downward pressure on the steel plate 203, causing the steel plate 203 to compress the ore and bring it into contact with the crushing zone of the toothed roller 106. When processing ore of different hardness, the speed of the motor 103 is adjusted, and the speed of the toothed roller 106 is changed via the reducer 104. The crushing zone protective cover 2 ensures operational safety, and the contact temperature sensor 109 continuously monitors the temperature of the bearing 107.

[0027] Example 3: A roller crusher includes a double-toothed roller crusher 1 and a crushing zone protective cover 2 hinged to the right side of its top end face. The double-toothed roller crusher 1 has a motor support base 102 on the top right side of its base 101. Two motors 103 and a reducer 104 are fixed on the motor support base 102. The output shaft of the motors 103 is connected to the power input shaft of the reducer 104 via a coupling. The crushing trough 105 is located on the left side of the upper surface of the base 101. Through holes are opened on its left and right side walls. Two toothed rollers 106 pass through the through holes and are adapted to two bearings 107 on both side end faces. The power input end of the toothed rollers 106 is connected to the power output shaft of the reducer 104. A heat-conducting copper plate 108 is fixed to the outside of the bearings 107. A contact temperature sensor 109 is fixed to the other side of the heat-conducting copper plate 108. The contact temperature sensor 109 transmits the bearing temperature data to the control box for display. The right side of the transparent cover 201 of the crushing zone protective cover 2 is connected to the top of the right side wall of the crushing trough 105 via two hinges 202. Several arc-shaped steel bars 204 are fixed to the top side wall of the inner cavity of the transparent cover 201. A steel plate 203 is fixed to the lower end face of the arc-shaped steel bars 204. The arc-shaped steel bars 204 provide downward pressure to make the steel plate 203 squeeze the ore into contact with the crushing zone of the toothed roller 106. After the equipment has been running for a long time, the contact temperature sensor 109 can detect abnormal temperature of the bearing 107 in time. The crushing zone protective cover 2 prevents ore from splashing and injuring people during the crushing process, ensuring stable operation of the equipment and personnel safety.

[0028] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: Two motors 103 fixed on the motor support 102 are started. The output shaft of the motor 103 transmits power to the power input shaft of the reducer 104 through a coupling. After the reducer 104 converts and adjusts the power, it drives two toothed rollers 106, which are rotatably installed in the inner cavity of the crushing trough 105, to rotate through its power output shaft. The crushing trough 105 is fixed on the left side of the upper surface of the base 101. The two toothed rollers 106 pass through through holes opened on the left and right side walls of the crushing trough 105 for the toothed rollers 106 to pass through. The sections located outside the crushing trough 105 are respectively adapted to two bearings 107 installed on the left and right end faces of the crushing trough 105. The bearings 107 provide support for the rotation of the toothed rollers 106 and reduce friction. When the ore is fed into the crushing trough 105, the crushing zone protective cover 2, which is hinged to the right side of the top end face of the double toothed roller crusher 1, comes into play. The right side of the transparent cover 201 of the crushing zone protective cover 2 is fixedly connected to the top of the right side wall of the crushing trough 105 through two hinges 202, which can prevent the ore from splashing out and injuring people during the crushing process. Several arc-shaped steel bars 204 fixedly connected to the top side wall of the inner cavity of the transparent cover 201 provide downward pressure elasticity for the steel plate 203 fixed to the lower end face of the arc-shaped steel bars 204, so that the steel plate 203 squeezes the ore, allowing the ore to better contact the crushing zone between the toothed rollers 106, thereby improving the crushing effect. During equipment operation, a contact temperature sensor 109 installed on the heat-conducting copper plate 108 on the outer surface of the bearing 107 monitors the operating temperature of the bearing 107 in real time. The temperature data transmission end of the contact temperature sensor 109 is connected to the control box via a wire and transmits the temperature data to the control box. The operating temperature data of the bearing 107 is displayed on the display panel on the control box. Operators can understand the operating status of the bearing 107 based on the displayed temperature data so as to deal with any problems that may occur in a timely manner.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
