Description

Technical Field

[0001] The utility model relates to the technical field of material lifting, in particular to a three-claw type ground cylinder material lifting machine. Background Art

[0002] Fermentation in a ground jar means burying the fermentation jar underground. This special ground jar fermentation process requires large investment, is sophisticated and complex, and is clean and hygienic. It has been continued in China for thousands of years. After the fermentation of the lees in the ground jar is completed, there is a process of taking the lees out of the jar buried underground.

[0003] After searching, the Chinese invention patent with application number CN202111281347.4 is an automatic floor cylinder material elevator developed and produced by our company before. It discloses a guide tube, a positioning mechanism is provided on the outside of the guide tube, and a toothed plate is provided on the outside of the guide tube. The toothed plate is connected to a mobile motor installed on the upper surface of the positioning mechanism through a gear meshing transmission, so that the guide tube can move up and down, and a rotating discharging mechanism is provided at the upper end of the guide tube. A lifting spiral rod is provided inside the guide tube, and a collecting cover is connected to the lower end of the guide tube. A spiral outer cover welded to the lifting spiral rod is provided on the inner side of the collecting cover, and a spiral tube outer gear is welded on the outer side of the upper end of the spiral outer cover, and a bottom plate inner gear is installed on the inner side of the collecting cover. The bottom plate inner gear is installed through the bottom plate inner gear installed The reduction idler wheel inside the collecting hood is meshed with the outer gear of the spiral tube for transmission connection. The bottom plate is welded to the lower end of the inner gear of the bottom plate, and a scraper is installed on the lower surface of the bottom plate through the scraper rotating shaft. The material is gathered by using the spike rake on the scraper. After gathering, the lifting spiral rod lifts the material to the rotating discharging mechanism. The scraper is in an arc shape, and the number of scrapers is four groups. In actual use, we found that under the same usage conditions, the arc length of each group of scrapers in the four groups of scrapers will be shorter. If the hoist is not located in the center of the ground cylinder, one or two local scrapers will not be able to touch the cylinder wall because the scraper is far away from the cylinder wall, resulting in a large flipping angle. When it rotates to a position close to the cylinder wall, it will get stuck, which can easily damage the scraper and greatly reduce the safety and stability of the hoist.

[0004] Secondly, the use of a lifting screw rod to lift the material causes excessive squeezing pressure on the material, which affects the shape of the material and makes the materials tighter. Using these materials will affect the quality of the subsequent wine. Summary of the invention

[0005] The purpose of the utility model is to provide a three-claw ground cylinder material elevator to solve the problems of the four sets of scrapers in the above-mentioned background technology being easily damaged and the lifting spiral rod structure having too great an impact on the original shape of the material, resulting in reduced wine quality.

[0014] (1) By setting three groups of scrapers, the arc length of each group of scrapers becomes longer than that of four groups of scrapers.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] See also Figure 1-5The utility model provides an embodiment: a three-claw ground cylinder material hoist, including a support column 1, with reinforcing ribs 16 welded on both sides of the support column 1, the reinforcing ribs 16 are fixedly connected to the annular support plate 2 by bolts, a slewing bearing 3 is fixedly arranged at the bottom of the annular support plate 2, a motor 4 connected to the slewing bearing 3 is arranged on one side of the top of the annular support plate 2, a gear is arranged at the output end of the motor 4, the gear is meshed with the inner gear ring of the slewing bearing 3, and the inner gear ring is driven to rotate, and a scraper fixing ring 5 is fixedly connected to the bottom of the slewing bearing 3, That is, the inner gear ring drives the scraper fixing ring 5 to rotate, and the bottom of the scraper fixing ring 5 is rotatably connected with three groups of scrapers 6, which in turn drives the three groups of scrapers 6 to rotate. Under the premise that two groups of scrapers cannot complete the task of collecting materials, three groups of scrapers 6 are used in the same specification and size, and the arc length of each group of scrapers 6 is longer. In this way, it can be avoided that the scraper is damaged due to the shorter arc length of each group of scrapers in the four groups of scrapers, resulting in excessive flipping angle. In addition, compared with the four groups of scrapers, the three groups of scrapers have one less set of rotating connection devices in terms of manufacturing cost, which has the advantages of reducing cost and improving manufacturing efficiency.

[0026] A plurality of material collecting tube assemblies 7 are fixedly connected to the bottom of each group of scrapers 6, and each material collecting tube assembly 7 includes a support rod 71, the top of the support rod 71 is threadedly connected to the scraper 6, a spring 72 is welded to the outside of the support rod 71, the length of the spring 72 is greater than the length of the support rod 71, and a silicone tube 73 is sleeved on the outside of the spring 72. During the material collection operation in the ground cylinder, the space at the bottom of the ground cylinder is small, and the scraper 6 can no longer enter. The material collecting tube assembly 7 can rely on the characteristics of the softer spring 72 and the silicone tube 73 that are easy to deform to collect the material at the bottom of the ground cylinder; secondly, during the material collection process, the material collecting tube assembly 7 contacts the material earlier than the scraper 6, and loosens the material in advance, making it easier for the scraper to collect the material.

[0027] A driving motor 8 is provided at the inner bottom of the support column 1, and driving sprockets 9 are respectively provided on both sides below the support column 1. The driving sprocket 9 is transmission connected to the driving motor 8, wherein the output end of the driving motor 8 passes through the bottom of the support column 1 and is transmission connected to a right-angle commutator 15, and the output ends on both sides of the right-angle commutator 15 are fixedly connected to the driving sprocket 9. Through the commutation of the right-angle commutator 15, the force is transmitted to the driving sprockets 9 on both sides to drive the driving sprocket 9 to rotate.

[0028] A horizontal cross arm 10 is fixedly arranged on the top of the support column 1, and driven sprockets 11 are respectively arranged on both sides of the corners and ends of the horizontal cross arm 10, and an extended pin conveying chain 12 is transmission-connected between the driving sprocket 9 and the driven sprocket 11, and an idler wheel assembly 13 is arranged between the horizontal cross arm 10 and the support column 1, and the idler wheel assembly 13 is transmission-connected with the extended pin conveying chain 12, wherein the idler wheel assembly 13 includes a first idler wheel 131 which is respectively arranged below both sides of the horizontal cross arm 10 and coplanar with the driven sprocket 11, and a second idler wheel 132 which is coplanar with the driven sprocket 11. A first mounting frame 132 is provided between an idler wheel 131 and the horizontal cross arm 10, one end of the first mounting frame 132 is fixedly connected to the horizontal cross arm 10, and the other end is rotatably connected to the first idler wheel 131, a second idler wheel 133 is provided on the side of the support column 1 close to the first idler wheel 131, and a second mounting frame 134 is provided between the second idler wheel 133 and the support column 1. By providing two idler wheels, the transition of the extended pin conveying chain 12 at the corner of the horizontal cross arm 10 and the support column 1 is smoother.

[0029] Multiple buckets 14 are rotatably connected between the extended pin conveying chains 12 at equal intervals. Two rows of mounting rings 141 compatible with the extended pin conveying chain 12 are distributed up and down on one side of each bucket 14 close to the extended pin conveying chain 12, and the long pins of the extended pin conveying chain 12 are rotatably connected to the mounting rings 12.

[0030] Furthermore, one end of the scraper blade 6 is rotationally connected to the scraper blade fixing ring 5 via a rotating shaft, a torsion spring is provided between the rotating shaft and the scraper blade 6, and the other end of the scraper blade 6 is rotationally connected to a guide wheel 61. When the scraper blade 6 encounters material during its rotation, the material generates a thrust on the scraper blade 6 to move the scraper blade toward the cylinder wall, causing the scraper blade 6 to slowly open. When it touches the cylinder wall, in order to prevent damage to the cylinder wall, the guide wheel 61 will rotate along the cylinder wall to avoid damage caused by direct contact of the scraper blade 6 with the cylinder wall.

[0031] Furthermore, a screw rod 17 is provided on one side of the top of the annular support plate 2, and a screw lift 18 is provided on the outer side of the screw rod 17. The entire elevator is transported by an external moving tool. The screw lift 18 is connected to the external moving tool. After moving into position, the screw lift is used to control the rising and lowering operations of the material elevator.

[0032] When the embodiment of the present application is in use: first, use an external moving tool to move the ground cylinder material elevator to the ground cylinder. The moving tool can be a small crane or a carrier. After reaching the top of the ground cylinder and aligning it with the center of the ground cylinder, start the screw lift 18 to make the screw 17 descend and drive the entire elevator to start descending. During the descent, start the motor 4, which drives the gear ring in the slewing bearing 3 to rotate, and the gear ring drives the scraper fixing ring 5 at the bottom to rotate, thereby realizing the rotation of the scraper. When it does not contact the material, the scraper 6 is kept in a gathered state by the setting of the internal torsion spring of the scraper 6. When it starts to contact the material The silicone tube 73 in the collecting pipe assembly 7 first contacts the material, loosens the material and gathers it to the middle. When the scraper 6 contacts the material, the material generates a reaction force on the scraper, causing the scraper 6 to flip toward the cylinder wall. During the rotation and outward flipping of the scraper 6, the material is gathered to the middle of the cylinder. When the scraper 6 flips to contact the cylinder wall, that is, the guide wheel 61 contacts the cylinder wall, the scraper 6 stops flipping outward and only rotates around the center of the cylinder. When the diameter of the ground changes during the downward process, the guide wheel 61 will give the scraper a certain thrust, causing the scraper 6 to gather at a certain angle.

[0033] After the materials are gathered in the middle, the driving motor 8 is started to drive the driving sprocket 9 to rotate, and the extended pin conveying chain 12 meshing on the outside of the driving sprocket 9 starts to move. The movement direction is from the driving sprocket 9 to the driven sprocket 11 located at the corner of the horizontal cross arm 10, and then to the driven sprocket 11 at the end of the horizontal cross arm 10, and finally returns to the driving sprocket 8 through the idler wheel assembly 13. The bucket 14 connected to the internal rotation of the extended pin conveying chains 12 on both sides scoops the material from the bottom of the support column 1, and after transporting it to the driven gear 11 at the end of the horizontal cross arm 10, it is lifted and dumped, thereby achieving the purpose of transporting the material from the ground cylinder to above the ground for subsequent processing.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
