Description

Technical Field

[0001] The utility model relates to the technical field of floor scales, in particular to a sinking weighing floor scale. Background Art

[0002] A floor scale is a large scale set on the ground, usually used to weigh the tonnage of a truck's cargo. It is also called a truck scale. It is the main weighing equipment used by factories, mines, businesses, etc. to measure bulk goods. Before the 1980s, common floor scales were generally mechanical floor scales with a purely mechanical structure using the principle of leverage, also known as mechanical floor scales. In the mid-1980s, with the increasing maturity of high-precision weighing sensor technology, more and more floor scale brands entered the Chinese market.

[0003] After searching, a sinking scale is disclosed in the announcement number: CN218496243U, which relates to the technical field of scales. The sinking scale includes a scale body, a mounting assembly and a ring beam. The scale body is fixedly mounted inside the mounting assembly, the force-bearing surface of the scale body faces upward, the mounting assembly is fixedly mounted inside the foundation pit, the ring beam is located between the mounting assembly and the foundation pit, and the scale body, the outer wall of the foundation pit, and the mounting assembly are all located on the same horizontal plane. Through the above structure, when the heavy object starts to be weighed, the staff places the heavy object on the force-bearing surface of the scale body. The horizontal force on the scale body at this time is zero, avoiding the horizontal impact of the heavy object on the scale. At the same time, when the heavy object starts to move, the friction between the heavy object and the scale body is transmitted to the ring beam, thereby avoiding the phenomenon that the scale body becomes loose after being used for too long. The weighing scale in the application is inconvenient to be taken out from the ground, which makes it inconvenient to dismantle it, which will delay the subsequent project progress and cause its handling efficiency to be low.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-2 The utility model provides an embodiment: a sinking weighing scale, comprising a protective shell 1, both sides of the outer wall of the protective shell 1 are fixedly connected with a double-headed motor 6, the output ends of the double-headed motor 6 are fixedly connected with a driving wheel 7, the protective shell 1 is internally rotatably connected with a rectangular array of driven wheels 9, a belt 8 is arranged between the driven wheel 9 and the driving wheel 7, the driven wheel 9 is internally threadedly connected with a screw rod 2, the screw rod 2 is slidably connected to the inside of the protective shell 1, the bottom of the screw rod 2 is fixedly connected with a base 10, the protective shell 1 is internally fixedly connected with a bracket 13, and the top of the bracket 13 is fixedly connected with a scale body 4;

[0025] Specifically, the double-headed motor 6 drives the driving wheel 7 to rotate, and the driving wheel 7 is connected to the belt 8, thereby transmitting the rotational force to the driven wheel 9, so that the driven wheel 9 rotates to control the descent of the screw rod 2. When the driven wheel 9 rotates, the screw rod 2 descends accordingly. At this time, the base 10 at the bottom of the screw rod 2 provides stable support for the weighing scale, thereby taking the weighing scale out of the ground.

[0026] Reference Figure 1-2 The outer wall of the protective shell 1 is provided with an auxiliary component, which includes a deceleration rod 3 and a protruding rod 5. One side of the outer wall of the protruding rod 5 is fixedly connected to the outer wall of the protective shell 1, and the bottom of the deceleration rod 3 is fixedly connected to the top of the protective shell 1;

[0027] Specifically, a protruding rod 5 is provided on the outer wall of the protective shell 1, so when the protective shell 1 is fixed underground, it can prevent the protective shell 1 from sliding and causing inaccurate measurement data. Deceleration rods 3 are provided on both sides of the top of the protective shell 1, so that the vehicle will be appropriately decelerated when entering the weighing scale, thereby avoiding damage to the weighing scale body 4.

[0028] Reference Figure 3-5 A rectangular array of drainage grooves 11 are provided on the inner wall of the protective shell 1, and drainage plates 12 are fixedly connected on both sides of the bottom wall inside the protective shell 1. The drainage plates 12 are arranged at the bottom of the drainage grooves 11. A rectangular array of dredging grooves 14 are provided inside the protective shell 1, and the dredging grooves 14 are arranged between the drainage plates 12 on both sides. A rectangular array of filter screens 15 are provided inside the protective shell 1, and the filter screens 15 are slidably connected inside the dredging grooves 14. A rectangular array of slide grooves 20 are provided inside the protective shell 1, and card slots 17 are provided on both sides of the outer wall of the filter screen 15. Handles 16 are fixedly connected on both sides of the outer wall of the filter screen 15. A rectangular array of card balls 18 are provided inside the protective shell 1, and the card balls 18 are slidably connected inside the slide grooves 20. The card balls 18 are slidably connected inside the card slots 17. A spring 19 is fixedly connected to one side of the outer wall of the card ball 18, and one end of the spring 19 is fixedly connected to the inner wall of the slide groove 20;

[0029] Specifically, when rainy weather comes, rainwater flowing into the weighing scale will flow to the bottom of the protective shell 1 through the drainage groove 11. At the bottom of the protective shell 1, we set a drainage plate 12. The function of the drainage plate 12 is to guide the rainwater to the central position, so as to facilitate the discharge of rainwater. In order to ensure the smooth discharge of rainwater, a dredging groove 14 is designed at the central position. A filter 15 is set on the inner side of the dredging groove 14. The function of the filter 15 is to filter large particles of impurities in the rainwater to avoid the accumulation of impurities and cause the dredging groove 14 to be blocked. In addition, the installation and cleaning of the filter 15 are also very convenient. We have designed a handle 16. The user can use a pulling force to make the card ball 18 overcome the force of the spring 19, and pull the filter 15 out of the dredging groove 14 for cleaning. When the filter 15 is installed, the card ball 18 will slide out of the slide groove 20 under the action of the spring 19, and then be stuck in the card slot 17. In this way, the card slot 17 can fix the filter 15 to ensure that it will not shift during work.

[0030] Working principle: When the weighing scale is taken out from the ground, the double-headed motor 6 can be used to drive the driving wheel 7 to rotate, and the driving wheel 7 will drive the driven wheel 9 to rotate through the belt 8, and at the same time, the rotation of the driven wheel 9 will cause the screw rod 2 to drop, so that the screw rod 2 will support the ground through the base 10 at the bottom, so as to lift the weighing scale out of the ground. When it rains, the rainwater flowing into the weighing scale will flow into the bottom of the protective shell 1 through the drainage groove 11, and gather to the center under the action of the drainage plate 12, so that the rainwater can be dredged. The dredging groove 14 is provided with a filter 15, which can filter large particles of impurities in the rainwater, thereby preventing the accumulation of impurities and causing blockage of the dredging groove 14. At the same time, the filter 15 can be pulled out from the dredging groove 14 through the handle 16, and the card ball 18 can be retracted into the chute 20 by pulling force to overcome the force of the spring 19, so that the filter 15 can be taken out for cleaning. When the filter 15 is installed, the card ball 18 will slide out of the chute 20 under the action of the spring 19, and then be stuck in the card slot 17, so that the card slot 17 can be fixed.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
