Description

Technical Field

[0001] The utility model relates to the technical field of grain weighing equipment, in particular to a convenient grain purchasing weighing device. Background Art

[0002] Grain refers to the various plant seeds used in cooking, and can also be broadly referred to as "cereals." Grain crops are rich in nutrients, primarily protein, vitamins, dietary fiber, fat, and starch. After harvest, grain needs to be sold to grain stations, where it is measured using weighing equipment.

[0003] The application number in the existing public technology is: CN202221923427.5 A precise weighing device for grain purchasing, which can expand the volume of the weighing frame by installing screws and barrels, and is simple to operate and avoids cumbersomeness. By expanding the opening of the component, the weighing frame can be easily slid to the surface of the weighing plate, avoiding the effect of manual movement. The four movable rollers at the bottom of the weighing frame slide into the inside of the mounting groove, thereby avoiding the movement and shaking of the weighing frame, and avoiding affecting the accuracy of grain weighing.

[0004] However, the above patent still has certain disadvantages when used: although it can perform relatively accurate weighing operations, it still uses manual handling and lifting to handle multiple grain bags when stacking them at one time. At this time, the personnel need to overcome gravity to do work, which not only increases the labor intensity of the personnel, but also greatly increases the fatigue of the personnel. Moreover, when weighing grain, a large number of grain bags are often involved, so the grain bags need to be stacked and unloaded frequently. As a result, the arms and waist will become tired when carrying the grain bags up and down for a long time, which will cause the grain bags to fall out of the hands, resulting in damage to the grain bags or even injury to the operator. The safety of weighing is not very good, and the overall use effect is not ideal.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0028] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the present utility model, a convenient grain purchasing weighing device is provided.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, the portable grain purchasing weighing device according to the embodiment of the present invention includes a weighing base 1 and a weighing device 2. A bearing seat 12 is symmetrically welded at the middle position of the bottom end of the two side surfaces of the weighing base 1, and a fixed plate 4 is welded at the top position of the bearing seat 12. A screw rod 5 is installed inside the fixed plate 4. One end of the screw rod 5 passes through one side of the fixed plate 4 and is connected to the motor 6. A connecting arm 3 is sleeved on the outer periphery of the screw rod 5. An expansion arm 13 is welded at the bottom position of one side surface of the connecting arm 3, and a bearing plate 15 is welded between the bottoms of the expansion arms 13. A guide plate 16 is welded at one end of the bearing plate 15. Several groups of rollers 17 are rotatably connected to the surface of the guide plate 16 and the surface of the bearing plate 15. Several groups of mounting grooves 14 are symmetrically opened around the top of the bearing plate 15, and an electric hydraulic rod 18 is installed inside the mounting groove 14.

[0031] In one embodiment, a weighing device 2 is installed on the top of the weighing base 1. The weighing device 2 is a basic component of the weighing device, so it will not be described in detail.

[0032] In one embodiment, a center plate 10 is installed in the middle position of the surface of one end of the weighing base 1, and several groups of connecting plates 8 are symmetrically welded on both sides of the center plate 10. A fence 7 is welded at one end of the connecting plate 8, and the bottom of the fence 7 is connected to the surface of the weighing base 1. The fence 7 is provided to prevent the grain bag from falling off from the side.

[0033] In one embodiment, an electronic display screen 9 is installed at the top of the center plate 10. The electronic display screen 9 is a common structure, and is mainly used to display the weighing value for easy processing by personnel.

[0034] In one embodiment, several groups of lockable movable wheels 11 are symmetrically installed around the bottom of the weighing base 1. The lockable movable wheels 11 are a common movable wheel structure, so they will not be described in detail. They are mainly for the convenience of moving the device and improving the ease of use. At the same time, they can be locked after moving to the designated position to prevent movement during weighing and ensure stability in use.

[0035] In one embodiment, a counterweight is installed on the side of the weighing base 1 away from the supporting plate 15. The counterweight is provided to ensure that the center of gravity of the device will not shift when the supporting plate 15 lifts the grain bag, thereby avoiding the device from tipping over and improving the stability of the device.

[0036] In one embodiment, a battery and a controller are provided inside the weighing base 1. The battery and the controller are common basic structures, so they will not be described in detail.

[0037] In one embodiment, the size of the supporting plate 15 is larger than that of the weighing base 1. The size of the supporting plate 15 is set to ensure that it can smoothly move the grain bag to the weighing base 1, thereby avoiding the grain bag being unable to be fully placed due to being too small.

[0038] Working principle: During actual use, personnel can place the grain bag loaded with grain on the weighing device 2 for weighing, and the weighed weight can be displayed on the electronic display screen 9 for personnel to know, and the lockable movable wheels 11 at the bottom can facilitate personnel to move the entire device, thereby improving the portability and flexibility of the device. When there are many grain bags involved, personnel can drive the screw rod 5 through the operation of the motor 6, and then move the supporting plate 15 to the ground position through the screw rod 5. Then, personnel can move the grain bag to the surface position of the supporting plate 15 by rotating the roller 17 on the surface, and then the electric hydraulic rod 18 can be used to block the four sides of the grain bag to prevent the grain bag from moving and falling during lifting, thereby preventing the fall from injuring personnel. The safety of weighing is improved, and then the supporting plate 15 can be lifted to the specified height by reversing the motor 6, and then the grain bag can be moved again by resetting the electric hydraulic rod 18, and then the personnel can easily push the grain bag so that the grain bag can be stacked on another grain bag, thereby realizing the operation of synchronous weighing of multiple grain bags. Relatively speaking, when the grain bag is unloaded later, it is only necessary to push the grain bag onto the supporting plate 15 to move it easily. During the entire process of loading and unloading the grain bag, there is no need for personnel to perform large-scale lifting operations on the grain bag, which effectively avoids the probability of arm fatigue and waist strain of personnel, can reduce the intensity of weighing operation, and is convenient for better use. The overall device has the advantages of labor-saving weighing, convenient loading and unloading, and high weighing safety.
