Description

Technical Field

[0001] The utility model belongs to the technical field of sorting machine devices, and particularly relates to a material crushing prevention feeding transmission device. Background Art

[0002] During the process of sorting, cleaning and other operations of materials, a feed conveying device is often required to transfer the materials to the corresponding equipment. The materials in the existing feed conveying mechanism usually fall onto the conveying mechanism through the feed port, and then the materials are transported to the sorting and other processing equipment through the conveying mechanism. The existing feed conveying device includes a conveying mechanism and a hopper located above the conveying mechanism. The hopper falls onto the conveying mechanism under the action of its own gravity. For materials that are easily broken, such as red dates and walnut kernels, the existing feed conveying process may cause damage to the surface of the materials, which affects the normal transportation and screening of materials to a certain extent. Utility Model Content

[0003] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a material anti-crushing feeding and conveying device to solve the problems mentioned in the background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A material crushing prevention feeding and transmission device comprises a conveying mechanism and a material guide trough installed on a frame, wherein the material guide trough is obliquely installed above the feeding end of the conveying mechanism, the top of the material guide trough is a material inlet, and the bottom of the material guide trough is a material outlet. The material inlet is horizontally away from the conveying mechanism relative to the material outlet, and the material guide trough is gradually inclined downward from the material inlet to the outlet. The difference between the prior art and the prior art is that:

[0006] It also includes a material blocking piece, the upper end of which is installed on the material guide trough, the lower end of which hangs down naturally and the tip extends into the material guide trough, and the material contacts the material blocking piece during the process of passing through the material guide trough, so that a discharge channel is formed between the material blocking piece and the bottom of the material guide trough, and the part of the material blocking piece that contacts the material can be deformed.

[0007] During the feeding and conveying process, the material enters the guide trough from the feeding port. After entering the guide trough, the material touches the material blocking member and causes the end of the material blocking member to move upward, thereby forming a discharge channel between the material blocking member and the bottom of the material guide trough. In this process, the material is blocked, and the relative speed of the material relative to the conveying mechanism in the vertical direction is reduced to avoid the surface of the material from being crushed. At the same time, the material is pressed downward by the end of the material blocking member to achieve dispersion of the material. The material falls from the discharge port to the conveying mechanism, and the conveying mechanism transmits the material horizontally.

[0008] Preferably, the upper end of the material blocking member has a portion located outside the material guiding trough, thereby increasing the displacement of the material blocking member relative to the material guiding trough, and further increasing the anti-crushing effect of the material blocking member on the material.

[0009] Preferably, the guide trough is provided with a limit plate, which is located above the material stopper and opposite to the middle of the material stopper. When the material stopper is naturally hanging without being subjected to force, a moving gap is formed between the material stopper and the limit plate. When the material stopper is subjected to a large upward force, the material stopper collides with the limit plate to limit the position of the material stopper. The limit plate is used to limit the displacement of the material stopper relative to the guide trough, to avoid material accumulation so that the end of the material stopper is located above the guide trough and the material is separated from the guide trough.

[0010] Preferably, an upper opening is formed above the limiting plate and the material guide trough, and the material blocking piece passes through the opening above and hangs down into the material guide trough. The length of the opening is greater than the thickness of the material blocking piece, and the length of the limiting plate is not less than one-fourth of the length of the material piece. On the premise of achieving the material dispersing and anti-crushing effects of the material blocking piece, the limiting effect of the limiting plate on the material blocking piece is guaranteed.

[0011] Preferably, a lower opening is formed below the limiting plate and the material guiding trough to facilitate observation of the transmission of the material in the material guiding trough.

[0012] Preferably, the material stopper may be made of elastic material such as rubber.

[0013] Preferably, the material blocking member is provided with a disconnected seam along the length direction, which extends to the end, and the lower end of the material blocking member is divided into unconnected material blocking strips by the disconnected seam, thereby reducing the downward pressure on the material while ensuring that the material is loose, thereby further avoiding damage to the material during the feeding and transmission process.

[0014] Preferably, the material retaining bar has a portion located outside the material guiding trough, thereby increasing the deformation or displacement of the material retaining bar according to the amount or size of the material.

[0015] Preferably, side baffles for limiting the material are provided on both sides of the conveying mechanism, and the side baffles and the conveying mechanism form a horizontal transmission channel. Buffer pads are attached to the inner side of the side baffles, which can be made of sponge or other elastic materials, thereby preventing the material from colliding with the side baffles and being damaged.

[0016] Preferably, an anti-sticking layer is provided on the inner side of the buffer pad, and the anti-sticking layer may be an anti-sticking cloth, thereby preventing the material from sticking to the side baffle.

[0017] Preferably, the distance from the discharge port of the material guide trough to the conveying mechanism in the vertical direction can be adjusted. Specifically, it is convenient to adjust the distance from the end of the material guide trough to the conveying mechanism in the vertical direction according to different materials, so as to avoid damage caused by collision between the material and the conveying mechanism.

[0018] Preferably, a separating through hole is also provided on the material blocking member, the outer diameter of the separating through hole is larger than the width of the fracture crack, and the separating through hole is located on the fracture joint. There can be multiple groups of separating through holes on a fracture joint, and the separating through holes separate the material blocking strip into at least two material blocking portions, and the width of the connecting portion between two adjacent material blocking portions is smaller than the width of the material blocking portions, thereby further preventing the breakage of the material and increasing the dispersion effect on the material.

[0019] The utility model proposes a material crushing prevention feeding and transmission device, which blocks the material by setting a material blocking member, reduces the relative speed of the material relative to the conveying mechanism in the vertical direction, avoids the surface crushing of the material, and presses the material downward by the end of the material blocking member to achieve material dispersion.

[0020] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figures 1 to 4The material anti-crushing feeding and transmission device shown in the figure includes a conveying mechanism 1 and a material guide trough 2 installed on a frame 5. The conveying mechanism 1 is a belt transmission mechanism. The material guide trough 2 is installed obliquely above the feeding end of the conveying mechanism 1. The top of the material guide trough 2 is the feeding port, and the bottom of the material guide trough 2 is the discharging port. The feeding port is horizontally far away from the conveying mechanism 1 relative to the discharging port. The material guide trough 2 is gradually inclined downward from the feeding port to the outlet, and also includes a material blocking member 3. The upper end of the material blocking member 3 is installed on the material guide trough 2, and the lower end of the material blocking member 3 naturally hangs down and the end extends into the material guide trough 2. When the material passes through the material guide trough 2, it contacts the material blocking member 3 and forms a discharging channel between the material blocking member 3 and the bottom of the material guide trough 2. The part of the material blocking member 3 that contacts the material can be deformed, and the material blocking member 3 is made of rubber material.

[0029] During the feeding and conveying process, the material enters the guide trough 2 from the feeding port. After entering the guide trough 2, the material touches the blocking member 3 and causes the end of the blocking member 3 to move upward, thereby forming a discharge channel with the bottom of the blocking member 3 and the bottom of the guide trough 2. In this process, the material is blocked, and the relative speed of the material relative to the conveying mechanism 1 in the vertical direction is reduced to avoid the surface of the material from being broken. At the same time, the material is pressed downward by the end of the blocking member 3 to achieve dispersion of the material. The material falls from the discharge port to the conveying mechanism 1, and the conveying mechanism 1 transmits the material horizontally.

[0030] Preferably, the upper end of the material blocking member 3 has a portion located outside the material guide trough 2. Specifically, the material inlet of the material guide trough 2 is provided with a material feed frame, and the upper end of the material blocking member 3 is detachably mounted on the outside of the upper side of the material feed frame by means of a pressure plate and fixing parts such as screws or bolts. During installation, the upper end of the material blocking member 3 is placed outside the material feed frame and pressed by a pressure plate, and then the material blocking member 3 is fixed to the material guide trough 2 by screws. Since the upper part of the material blocking member 3 is located outside the material guide trough 2, the displacement of the material blocking member 3 relative to the material guide trough 2 is increased, thereby further increasing the anti-crushing effect of the material blocking member 3 on the material.

[0031] Preferably, the guide trough 2 is provided with a limit plate 20, which can be fixed on the guide trough 2 by welding or other means, and the limit plate 20 is located above the material stopper 3 and opposite to the middle of the material stopper 3. When the material stopper 3 is naturally hanging without being subjected to force, a moving interval is formed between the material stopper 3 and the limit plate 20. When the material stopper 3 is subjected to a large upward force, the material stopper 3 collides with the limit plate 20 to limit the position of the material stopper 3. The limit plate 20 is used to limit the displacement of the material stopper 3 relative to the guide trough 2, to avoid material accumulation so that the end of the material stopper 3 is located above the guide trough 2 and the material is separated from the guide trough 2.

[0032] Preferably, an upper opening 21 is formed above the limiting plate 20 and the material guide trough 2, and the material blocking member 3 passes through the opening above and hangs down into the material guide trough 2. The length of the opening is greater than the thickness of the material blocking member 3, and the length of the limiting plate 20 is not less than one-fourth of the length of the material. On the premise of achieving the material dispersion and anti-crushing effects of the material blocking member 3, the limiting effect of the limiting plate 20 on the material blocking member 3 is guaranteed.

[0033] Preferably, the limiting plate 20 and the lower portion of the material guiding chute 2 form a lower opening 22 for conveniently observing the transmission of the material in the material guiding chute 2 .

[0034] like Figure 4 As shown, preferably, the material blocking member 3 is provided with a disconnecting seam 30 along the length direction, and the disconnecting seam 30 extends to the end. The lower end of the material blocking member 3 is divided into unconnected material blocking strips 31 by the disconnecting seam 30, which reduces the downward pressure applied to the material while ensuring that the material is loose by the material blocking member 3, thereby further avoiding damage to the material during the feeding and transmission process.

[0035] like Figure 4 As shown, preferably, the material blocking strip 31 has a portion located outside the material guiding trough 2, thereby increasing the deformation or displacement of the material blocking strip 31 according to the amount or size of the material.

[0036] Preferably, side baffles 4 for limiting the material are provided on both sides of the conveying mechanism 1. The side baffles 4 and the conveying mechanism 1 form a horizontal transmission channel. A buffer pad is attached to the inner side of the side baffle 4. The buffer pad can be made of sponge or other elastic materials, thereby preventing the material from colliding with the side baffle 4 and being damaged.

[0037] Preferably, an anti-sticking layer 6 is provided on the inner side of the buffer pad, and the anti-sticking layer 6 may be an anti-sticking cloth, thereby preventing the material from adhering to the side baffle 4 .

[0038] Preferably, the distance from the discharge port of the material guide trough 2 to the conveying mechanism 1 in the vertical direction can be adjusted. Specifically, it is convenient to adjust the distance from the end of the material guide trough 2 to the conveying mechanism 1 in the vertical direction according to different materials, so as to avoid damage caused by collision between the material and the conveying mechanism 1.

[0039] Specifically, a waist-shaped sliding hole is opened on the frame 5, and the material guide trough 2 is fixed on the waist-shaped hole of the frame 5 by a locking bolt. The length of the waist-shaped hole is greater than the outer diameter of the locking bolt. By adjusting the position of the locking bolt relative to the frame 5, the distance from the discharge port of the material guide trough 2 to the conveying mechanism 1 in the vertical direction can be adjusted.

[0040] like Figure 5In some embodiments shown in the figure, preferably, a separating through hole 32 is further opened on the material blocking member 3, the outer diameter of the separating through hole 32 is larger than the width of the fracture crack, and the separating through hole 32 is located on the fracture seam 30, and a fracture seam 30 can have multiple groups of separating through holes 32, and the separating through holes 32 separate the material blocking strip 31 into at least two material blocking portions, and the width of the connecting portion between two adjacent material blocking portions is smaller than the width of the material blocking portions, thereby further preventing the breakage of the material and increasing the dispersion effect on the material.
