[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 of 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] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides a material discharging mechanism for a sand drying machine.

[0026] In this embodiment, refer to Figure 1-4 The sand dryer discharging mechanism includes:

[0027] A buffer box 1, wherein a sand inlet 2 is provided at one end of the buffer box, a sand outlet 3 is provided at the other end, and a bottom wall of the buffer box is a sand guiding slope 4 inclined from the sand inlet to the sand outlet;

[0028] The lifting mechanism includes a lifting shell 5, a driven shaft 6 arranged in the lifting shell, a driving shaft 7 arranged in the lifting shell, a conveying crawler 8 arranged on the driven shaft and the driving shaft, a driving device 9 drivingly connected to the driving shaft, and a sand bucket 10 fixed on the conveying crawler at equal intervals. A feed port 11 is provided on one side of the lifting shell, and a discharge port 12 is provided on the other side. A discharge guide cylinder 13 is connected to the discharge port, and the feed port is connected to the sand discharge port through a material pipe 14.

[0029] The discharge mechanism of the sand dryer of the present application realizes the continuous and stable conveying of the dried sand by setting a buffer box and a lifting mechanism. The inclined sand guide slope of the buffer box can effectively guide the sand to flow to the sand outlet, and at the same time play a buffering role, ensuring the continuous and stable non-powered output of the sand, avoiding the problems of sand blockage and leakage. The lifting mechanism can lift the sand to a certain height, and finally the discharge guide tube flows out, so as to facilitate loading and other operations. This discharge mechanism has a simple structure and is easy to maintain, which can improve work efficiency, reduce energy consumption, and ensure safe operation.

[0030] Specifically, “H”-shaped support plates 15 are provided on both sides of the buffer box, and the support plates are connected to support brackets 17 via connecting columns 16 .

[0031] The "H"-shaped support plates and support brackets installed on both sides of the buffer box enhance the stability and load-bearing capacity of the entire discharging mechanism, and improve the service life and operational safety of the equipment.

[0032] Specifically, the sand inlet is connected to a buffer tube 18, which is an "N"-shaped structure. A guiding inclined bottom surface 19 is provided in the buffer tube for guiding the sand fed at the inlet end of the buffer tube to the outlet end of the buffer tube.

[0033] The "N" type buffer pipe and the guiding inclined bottom surface design connected to the sand inlet can effectively slow down the speed of sand entering the buffer box and reduce the impact of sand on the buffer box, thereby reducing the crushing of sand and the generation of dust. This design improves the sand conveying efficiency, reduces maintenance costs and improves the working environment.

[0034] Specifically, the inclination angle of the guiding inclined bottom surface is 25°-35°.

[0035] The inclination angle of the guiding inclined bottom surface is set to 25°-35°, which can ensure that the sand can be effectively decelerated when flowing in the buffer tube, and will not cause blockage due to excessive angle. This design optimizes the flow performance of the sand and ensures the efficient operation of the discharging mechanism.

[0036] Specifically, the inclination angle of the sand guiding slope is 30°-50°.

[0037] The inclination angle of the sand guide slope on the bottom wall of the buffer box is set to 30°-50°, which can make the sand slide out of the buffer box at an appropriate speed, avoiding sand accumulation and blockage, and ensuring that the sand can smoothly enter the lifting mechanism for the next step of lifting and transportation. This design improves the overall working efficiency and reliability of the discharging mechanism.

[0038] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
