DETAILED DESCRIPTION

[0038] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0039] like Figures 1 to 4 As shown, a hoist comprises a bracket 1, on which a transmission bar 5 is provided. The bracket 1 of the utility model comprises an inclined side, and the transmission bar 5 is provided with an inclined lifting section 2 corresponding to the inclined side. A lifting hopper 10 is connected to the inclined lifting section 2, and the inclined lifting section 2 can drive the lifting hopper 10 to transfer from the bottom of the bracket 1 to the top of the bracket 1.

[0040] The utility model has a turning section 3 at the top of the inclined lifting section 2, and the lifting hopper 10 can turn over on the turning section 3, thereby completing the transfer of materials at a certain height.

[0041] Specifically, the bracket 1 at the end of the flip section 3 is provided with a lower live material channel 4 inclined downward. After the lifting hopper 10 is flipped, the material in the lifting hopper 10 can be transferred to the lower live material channel 4. The bottom of the lower live material channel 4 of the utility model is hinged to the bracket 1, and an elastic support element 44 is hinged between the bottom of the lower live material channel 4 and the bracket 1. The elastic support element 44 is preferably configured as a hydraulic rod or an elastic plate or a spring shock absorber. After the material is put into the lower live material channel 4, it impacts the lower live material channel 4. Therefore, the lower live material channel 4 can vibrate repeatedly through the hydraulic rod or the elastic plate, so that the falling material can fall to different positions, avoiding collection at the same position, and can improve the screening efficiency and the conveying speed.

[0042] The lower active material channel 4 of the utility model comprises an upper screening channel 41 on the upper layer and a lower screening channel 42 on the lower layer. The upper screening channel 41 is preferably set as a screen or a plurality of cylindrical rollers with a certain spacing. After the material transferred to the lower active material channel 4 is screened by the upper screening channel 41, a part of the material is transferred through the upper screening channel 41, and the other part of the material is transferred through the lower screening channel 42.

[0043] A lower output port 43 is provided at the bottom of the lower screening channel 42 in the conveying direction. The output direction of the lower output port 43 is inconsistent with the output direction of the upper screening channel 41 to avoid re-mixing of the screened materials.

[0044] The above structure uses the inclined lifting section 2 and the turning section 3 to lift the material through the lifting hopper 10, and then turns it over and drops it onto the lower live material channel 4. The lower live material channel 4 with a double-layer screening channel structure can effectively separate the material and impurities such as foam, and can be used in automatic production lines with a certain degree of automatic feeding and screening materials, which greatly reduces the intensity of manual labor and realizes fully automatic production.

[0045] The bottom of the bracket 1 of the utility model is provided with a driving wheel 7 and a lower driven wheel 8, and the top of the bracket 1 is provided with an upper driven wheel 9. The driving wheel 7, the lower driven wheel 8 and the upper driven wheel 9 are sequentially connected through a transmission bar 5, so as to form a relatively stable triangle. Specifically, the transmission bar 5 between the lower driven wheel 8 and the upper driven wheel 9 is set as an inclined lifting section 2, and the transmission bar 5 above the upper driven wheel 9 is set as a flip section 3.

[0046] It also includes a tensioning wheel 12, which is located on the bracket 1 between the driving wheel 7 and the lower driven wheel 8, and the height of the tensioning wheel 12 is adjustable.

[0047] Specifically, a support seat 13 is provided at the bottom of the bracket 1, and a height-adjustable connecting rod 14 is provided on both sides of the support seat 13. The ends of the connecting rod 14 are fixedly connected with bearings 15. The center of the tensioning wheel 12 is connected with a rotating shaft, and the two ends of the rotating shaft are respectively connected to the bearings 15 at the ends of the two connecting rods 14. The tensioning degree of the transmission bar 5 can be adjusted by adjusting the lifting and lowering of the connecting rod 14.

[0048] The utility model provides two groups of transmission bars 5, which are respectively arranged on both sides of the bracket 1, so that the lifting load is increased and the lifting is smoother; similarly, the driving wheel 7, the lower driven wheel 8, the upper driven wheel 9 and the tensioning wheel 12 are also provided in two groups; a reduction motor 6 is provided on the bracket 1 between the two groups of transmission bars 5, and the two ends of the reduction motor 6 are respectively connected to the driving wheels 7 on both sides of the bracket 1 through transmission shafts. Since the above-mentioned reduction motor 6 is located at the bottom of the bracket 1 and at the center of the bracket 1, the overall stability of the entire hoist is improved. In addition, since the driving wheel 7 and the lower driven wheel 8 are also located at the bottom of the bracket 1, the center of gravity of the entire hoist is further lowered, thereby further improving the stability of the hoist.

[0049] The transmission bar 5 is configured as a chain or a synchronous belt; the corresponding driving wheel 7, the lower driven wheel 8, the upper driven wheel 9 and the tensioning wheel 12 are configured as sprocket wheels or synchronous belt wheels.

[0050] The utility model has a lifting hopper 10 that is rotatably connected to one side of the transmission bar 5, and the two ends of the rotating shaft 11 are connected to the transmission bars 5 on both sides of the bracket 1. The rotating shaft 11 drives the lifting hopper 10 to rise under the action of the transmission bar 5. When the lifting hopper 10 reaches the specified position, it turns over to pour out the materials.

[0051] Protective covers are preferably provided on the brackets 1 at the positions of the inclined lifting section 2 and the flipping section 3 on both sides of the lifting hopper 10 to prevent accidental falling of materials during transportation, thereby improving the safety factor and reducing safety hazards.

[0052] The specific working process of this utility model:

[0053] The initial position of the lifting hopper 10 is located at the bottom of the inclined lifting section 2. The lifting hopper 10 is filled with materials, the reduction motor 6 is started, and the transmission bar 5 rotates to drive the lifting hopper 10 to rise. After rising to a certain height, the lifting hopper 10 is turned over a certain angle to pour out the materials. The lifting hopper 10 can be turned over multiple times according to the actual usage conditions.

[0054] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
