DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] To solve the technical problem of material loss caused by the sliding of grain from both sides of the belt, the present utility model provides a belt conveyor that can prevent material loss.

[0024] It should be noted that the belt conveyor described in the present utility model is used for but not limited to grain transmission, etc. For the convenience of description, in the present utility model, only a belt conveyor applied to a grain transmission device is taken as an example for illustration, and the principle of a belt conveyor applied to other types of devices is essentially the same as that applied to a grain transmission device, and will not be elaborated one by one here.

[0025] Please refer to Figure 1 - Figure 3 where Figure 1 is a schematic structural diagram of a belt conveyor in an embodiment of the present utility model. A belt conveyor includes a fixed frame 100, a conveyor belt 200, a protective cover 300, a slow-release strip 400, and a driving member 500; the two ends of the fixed frame 100 are respectively provided with a feeding end 110 and a discharging end 120; the conveyor belt 200 is installed on the fixed frame 100; the protective cover 300 is detachably connected to the fixed frame 100 and is located above the conveyor belt 200; the slow-release strip 400 is installed on the conveyor belt 200, and a groove 410 is opened at the slow-release strip 400 near the feeding end 110; the driving member 500 is arranged on one side of the fixed frame 100 and is used to drive the conveyor belt 200 to rotate.

[0026] In this embodiment, by providing the protective cover 300 on the fixed frame 100, it can effectively prevent the grain from sliding off both sides of the conveyor belt 200; further, by providing the slow-release strip 400 on the conveyor belt 200 and opening the groove 410 near the feeding end 110, part of the grain can fall into the groove 410 during grain feeding, effectively blocking the dispersion of the grain and enhancing the effect of gathering the grain within the unit surface area, thereby avoiding the problem of incoming material loss.

[0027] In one of the embodiments, please refer to Figure 2 , the slow-release strip 400 is in an arc shape, and the convex side faces away from the conveyor belt 200.

[0028] In this embodiment, the slow-release strip 400 being in an arc shape and the convex side facing away from the conveyor belt 200 can make part of the grain temporarily stay on one side of the slow-release strip 400, avoiding the large-scale and disorderly dispersion of the grain.

[0029] In one of the embodiments, please refer to Figure 2 , the inner bottom surface of the groove 410 is an arc surface.

[0030] In this embodiment, the inner bottom surface of the groove 410 being an arc surface can make part of the grain enter the groove 410, avoiding the rapid dispersion caused by excessive accumulation of the grain during feeding, resulting in serious classification and sliding off both sides.

[0031] In one embodiment, please refer to Figure 1 , the slow-release strips 400 are arranged in groups, and each group is evenly distributed along the transmission direction of the conveyor belt 200, and different groups are evenly distributed along the width direction of the conveyor belt 200.

[0032] In this embodiment, the distribution of the slow-release strips 400 helps to avoid the rapid dispersion of grains and enhance the gathering effect of grains in a local area. The gathering here specifically refers to that a large amount of grains will stay on one side of the adjacent slow-release strips 400, avoiding excessive accumulation. This part of the grains will be discharged through the discharging end 120 along with the transmission of the conveyor belt 200.

[0033] In one embodiment, please refer to Figure 1 , positioning holes 210 are correspondingly formed in the conveyor belt 200, and the bottom ends of the slow-release strips 400 extend into the positioning holes 210 and are clamped with the positioning holes 210.

[0034] In this embodiment, the positioning holes 210 and the bottom ends of the slow-release strips 400 are in transitional fit, and not all of the positioning holes 210 need to use the slow-release strips 400, and they can be filled with plugs correspondingly.

[0035] In one embodiment, please refer to Figure 1 , the length dimension of the protective cover 300 is at least one-half of the length dimension of the conveyor belt 200.

[0036] In this embodiment, the length dimension of the protective cover 300 can be designed according to the feeding amount of grains per unit time and the smoothness of the grains during transportation on the conveyor belt 200. It should be noted that, for heat dissipation and observation considerations, the length dimension of the protective cover 300 can only be less than the length dimension of the conveyor belt 200.

[0037] In one embodiment, please refer to Figure 1 , Figure 3 , the bottom end of the protective cover 300 is magnetically connected to both sides of the top end of the fixing frame 100.

[0038] In this embodiment, the magnetic connection between the bottom end of the protective cover 300 and both sides of the top end of the fixing frame 100 facilitates the operator to disassemble and assemble the protective cover 300 and subsequent maintenance.

[0039] In one embodiment, please refer to Figure 3 , a dust-absorbing flannelette 600 is pasted on the concave side of the protective cover 300.

[0040] In this embodiment, the dust-absorbing flannelette 600 pasted on the concave side of the protective cover 300 can adsorb the dust rising during the grain transportation process and improve the air environment around the equipment. The dust-absorbing flannelette 600 can be taken out and cleaned regularly.

[0041] In one embodiment, please refer to Figure 1 , press wheels 700 are arranged on two opposite inner sides of the fixing frame 100, and the press wheels 700 are used to abut against the conveyor belt 200.

[0042] In this embodiment, the press wheels 700 mainly play a role in guiding and flattening the conveyor belt 200, so as not to affect the normal transmission of the conveyor belt 200.

[0043] In one embodiment, please refer to Figure 1 , the driving member 500 is set as an asynchronous motor 510.

[0044] In this embodiment, setting the driving member 500 as an asynchronous motor 510 can make the driving member 500 easy to maintain and can meet the requirement of the low-speed rotation of the conveyor belt 200.

[0045] In order to better understand the present utility model, the technical solutions of the present utility model will be described in detail below in conjunction with Figures 1 to 3 :

[0046] First, start the driving member 500 to make the conveyor belt 200 rotate; then, pour grains through the feeding end 110. Some grains will stay on one side of the slow-release strip 400, and some grains will enter the groove 410, so that the grains will not pile up too high and cause a situation of rapid dispersion; in addition, since a protective cover 300 is provided on the conveyor belt 200, even if a small amount of grains slide to both sides of the conveyor belt 200, they will not slide out, thus effectively avoiding the loss of grains.

[0047] The above specific embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
