Description

Technical Field

[0001] The utility model relates to the technical field of stone removing machines, and particularly relates to a stone removing machine. Background Art

[0002] Before grains are processed, impurities such as stones in the grains need to be removed. The removal of stones is achieved by a stone removing machine. When the stone removing machine processes grains, the grains are poured into a hopper. The grains fall on the top of an inclined sieve plate. The sieve plate is driven to vibrate by a vibrator. Due to the different densities and specific gravities of the grains, the stones will move upward along the inclined sieve plate, and the grains will move downward along the sieve plate, realizing the separation of the grains and the stones.

[0003] When the mixture of grains and stones falls from the hopper onto the sieve plate, the grain mixture is piled up together. The grain mixture is spread out by the vibration force of the vibrator at the bottom of the sieve plate, but it takes a certain amount of time for the grain mixture to spread out, and the stone removing efficiency is low. Therefore, the present application provides a stone removing machine to meet the demand. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a stone removing machine to solve the problem of low stone removing efficiency when the grains in the stone removing machine are piled up.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A stone removing machine includes a stone removing machine body and a sieve plate. Grain discharge ports and stone discharge ports are respectively opened on two opposite sides of the stone removing machine body. The sieve plate is inclined and installed in the stone removing machine body and penetrates through the grain discharge ports and the stone discharge ports. A vibrator is installed at the bottom of the sieve plate. A hopper is fixed to the inner wall of the stone removing machine body. It further includes:

[0007] A material distribution mechanism. The material distribution mechanism includes a connecting pipe communicated with the discharge port of the hopper. The discharge port of the connecting pipe is communicated with a housing. The housing and the connecting pipe are located in the stone removing machine body. An inner cavity is opened inside the housing. A through groove communicated with the inner cavity is opened on the surface of the housing. A diversion block is fixed to one side of the inner wall of the housing close to the through groove. Two symmetrically arranged diversion curved surfaces are arranged at the bottom of the diversion block. A diversion inclined surface is arranged at the top of each of the two diversion curved surfaces.

[0008] Preferably, the bottom of the housing is arranged as an inclined surface, and the inclined angle of the bottom inclined surface of the housing is the same as that of the sieve plate.

[0009] Preferably, the distance between the bottom of the housing and the top of the sieve plate is greater than the diameter of the grains.

[0010] Preferably, the side of the diversion curved surface away from the diversion inclined surface is located in the through groove.

[0011] Preferably, a pre-screening component is arranged inside the outer shell. The pre-screening component includes several sieve bars fixed inside the outer shell. A through opening communicating with the inner cavity is formed on the side surface of the outer shell, and the through opening is used for discharging impurities screened out by the sieve bars.

[0012] Preferably, the sieve bars are inclined, and the inclination direction of the sieve bars is opposite to the inclination direction of the sieve plate.

[0013] Preferably, the distance between two adjacent sieve bars is greater than the diameter of the grains.

[0014] Preferably, a slope is arranged on the side of the through opening close to the sieve bars.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above solution, by arranging the material distribution mechanism, after the grain mixture falls inside the outer shell, it is distributed through the diversion slope of the diversion block, and then the grains slide onto the top of the sieve plate through the diversion curved surface, so that the grains are directly dispersed on the top of the sieve plate, saving the time for spreading the grain mixture and improving the stone removal efficiency.

[0017] By arranging the pre-screening component, after the grain mixture passes through the sieve bars, larger stones are screened out first and slide down from the through opening, and the position where the stones fall is the upward movement direction of the stones on the top of the sieve plate. They move upward together with the stones on the top of the sieve plate, avoiding the re-mixing of larger stones with the grains and further improving the stone removal efficiency.

[0030] Such as Figures 1 - 5As shown in the figure, an embodiment of the present utility model provides a stone removing machine, which includes a stone removing machine body 1 and a sieve plate 3. Grain discharge ports and stone discharge ports are respectively arranged on two opposite sides of the stone removing machine body 1. The sieve plate 3 is inclined and installed in the stone removing machine body 1 and penetrates through the grain discharge port and the stone discharge port. A vibrator is installed at the bottom of the sieve plate 3. A hopper 2 is fixed on the inner wall of the stone removing machine body 1. The stone discharge port is located on the left side of the stone removing machine body 1, and the grain discharge port is located on the right side of the stone removing machine body 1. It further includes:

[0031] A material distribution mechanism 4, which includes a connecting pipe 41 connected to the discharge port of the hopper 2. The discharge port of the connecting pipe 41 is communicated with a housing 42. The housing 42 and the connecting pipe 41 are located in the stone removing machine body 1. An inner cavity is opened inside the housing 42. A through groove 44 communicated with the inner cavity is opened on the surface of the housing 42. A diversion block 43 is fixed on the inner wall of the housing 42 near the through groove 44. Two symmetrically arranged diversion curved surfaces 432 are arranged at the bottom of the diversion block 43. A diversion inclined surface 431 is arranged at the top of each of the two diversion curved surfaces 432. The diversion inclined surface 431 is used for diverting the grain mixture, and the diversion curved surface 432 is used for guiding the grain mixture, so that the grain mixture can smoothly slide to the top of the sieve plate 3, avoiding the accumulation of the grain mixture in the housing 42.

[0032] As Figure 2 shown, in this embodiment, the bottom of the housing 42 is arranged as an inclined surface, and the inclination angle of the bottom inclined surface of the housing 42 is the same as that of the sieve plate 3. At this time, after the inclination angles of the bottom of the housing 42 and the sieve plate 3 are the same, the grain mixture is evenly discharged from the through groove 44, further improving the overall stone removal rate.

[0033] As Figure 2 shown, in this embodiment, the distance between the bottom of the housing 42 and the top of the sieve plate 3 is greater than the diameter of the grain to prevent the grain from getting stuck between the bottom of the housing 42 and the sieve plate 3. Moreover, during the vibration of the sieve plate 3, the sieve plate 3 will not contact the bottom of the housing 42, avoiding accidental damage to the sieve plate 3 due to collision.

[0034] As Figure 4 shown, in this embodiment, the side of the diversion curved surface 432 away from the diversion inclined surface 431 is located in the through groove 44. After the grain contacts the diversion curved surface 432, it slides along the direction of the diversion curved surface 432, and the grain is smoothly discharged from the through groove 44.

[0035] As Figures 4 - 5 shown, in this embodiment, a pre-screening assembly 5 is arranged in the housing 42. The pre-screening assembly 5 includes a plurality of sieve bars 51 fixed in the housing 42. A through port 52 communicated with the inner cavity is opened on the side of the housing 42. The through port 52 is used for discharging the impurities screened out by the sieve bars 51. The larger stones in the grain are pre-screened out by the sieve bars 51, avoiding subsequent screening, making it more convenient to use. Moreover, the opening direction of the through port 52 is the direction in which the stones on the sieve plate 3 move upward.

[0036] like Figure 2 As shown, in this embodiment, the screen bars 51 are inclined, and the inclination direction of the screen bars 51 is opposite to the inclination direction of the screen plate 3. When the screen plate 3 is vibrating, the stones move to the high position of the screen plate 3, and the grains move downward along the screen plate 3. The low point position of the screen bars 51 corresponds to the tilted position of the screen plate 3.

[0037] like Figure 2 As shown, in this embodiment, the distance between two adjacent screen bars 51 is larger than the diameter of the grain. Only when the distance is larger than the diameter of the grain, the grain can be discharged from the screen bars 51, while the larger stones move downward along the screen bars 51.

[0038] like Figure 4 As shown, in this embodiment, a slope is provided on the side of the through opening 52 close to the screen bar 51 to prevent stones from accumulating at the position of the through opening 52 and ensure the overall stable operation.

[0039] Working principle: start the vibrator at the bottom of the sieve plate 3, drive the sieve plate 3 to vibrate through the vibrator, pour the grain mixture into the hopper 2, and the grain mixture will fall from the connecting pipe 41 into the outer shell 42 due to its own gravity, and in the process of descending in the outer shell 42, the grain mixture will first pass through the sieve bar 51, and after passing through the sieve bar 51, the larger stones in the grain mixture will be screened out by the sieve bar 51 first, and then the larger stones will roll down along the sieve bar 51, and finally fall on the top of the sieve plate 3 at the moving opening 52, and at the same time, the grain mixture continues to fall downward, and when the grain mixture passes through the diversion block 43, the grain mixture will be diverted by the diversion slope 431, and the grain mixture will be diverted. The mixture will be divided into two parts, flowing from the diversion surface 432 to the position of the through groove 44, and finally falling evenly on the top of the sieve plate 3 from the position of the through groove 44. After the grain mixture falls evenly on the sieve plate 3, the grain mixture does not pile up together, reducing the time for spreading the grain mixture. The grain mixture directly enters the screening stage. At this time, due to the difference in specific gravity and density between the grains and stones, and the vibration of the sieve plate 3, the stones in the grain mixture move upward along the inclined direction of the sieve plate 3 and are discharged from the stone discharge port. At this time, the stones will contact the larger stones falling from the through port 52, and the grains move downward along the sieve plate 3 and are discharged from the grain discharge port, and finally the grains are collected.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
