Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and in particular to a grain feeding mechanism for a grain dryer. Background Technology
[0002] Grain dryers are often used to dry grains before storage to prevent them from spoiling due to excessive moisture during storage. Existing grain dryers usually have a grain-dispersing layer above the discharge port to change the direction of the grain falling from the drying layer, thereby dispersing the dried grain and preventing it from accumulating at the discharge port during the feeding process. This would prevent moisture from re-entering the dried grain and causing it to stick together and affect the drying effect.
[0003] Existing grain-distributing mechanisms in grain-distributing layers, such as the grain-separating component described in CN207922817U "A Grain-Distributing Layer for a Grain Dryer," include a shell and a grain-distributing mechanism disposed within the shell. It also includes one or more grain-separating components disposed within the shell. Each grain-separating component is a strip-shaped structure with an inverted V-shaped cross-section, formed by connecting a left and right baffle. Both the left and right baffles have multiple ventilation holes. Because the grain-separating component is a triangular structure with its apex pointing upwards, its sharp upper part can break up the grain as it falls, effectively dispersing it. Furthermore, the ventilation holes on the left and right baffles allow hot air from the dryer to pass upwards through the ventilation holes and act on the grain falling on the left and right baffles, thus drying and dispersing the grain and preventing grain clumping on the left and right baffles. However, in actual use, when a large amount of grain enters the grain feeding layer from the drying layer, due to the limited gap between the grain separating component and the grain feeding roller in the grain feeding mechanism, even if the grain is fed through the rotation of the grain feeding roller, the grain will still accumulate in the grain feeding layer, causing blockage and affecting the drying effect of the grain. Moreover, when the grain feeding roller malfunctions and cannot feed the grain, after the blockage occurs in the grain feeding layer, the grain can only be fed through the gap between the grain separating component and the grain feeding roller, which cannot achieve rapid feeding and maintenance. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a grain feeding mechanism for a grain dryer, which is mainly used to disperse the grain after it has been dried by the drying layer, so as to achieve the purpose of dispersing the grain during normal feeding and quickly discharging the grain when there is blockage.
[0005] This utility model discloses a grain feeding mechanism for a grain dryer, comprising a grain feeding assembly and a grain separating component arranged along the length of the grain feeding layer. The grain feeding assembly includes a guide and a feeding roller. The guide includes a guide plate with an inverted V-shaped cross-section, comprising a left guide plate and a right guide plate. The lower ends of the left and right guide plates are provided with horizontal plates extending outward in a horizontal direction. Above each horizontal plate is a feeding roller rotatably connected to the grain feeding layer. The left and right guide plates are evenly provided with discharge holes. Below each discharge hole is a baffle assembly for controlling the opening and closing of the discharge hole. At least two sets of grain feeding assemblies are evenly arranged in the grain feeding layer. The grain separating component is located above the space between two adjacent feeding rollers.
[0006] Furthermore, the material blocking assembly includes an operating rod that penetrates the grain feeding layer and moves along the length of the grain feeding layer, and a material blocking block that corresponds to each of the material discharge holes is fixed on the operating rod.
[0007] As a preferred embodiment, the end of the operating lever located outside the grain feeding layer is provided with a limiting member to restrict the movement of the operating lever, and the end of the operating lever opposite to the limiting member is provided with an operating handle.
[0008] Furthermore, the material blocking assembly includes an operating rod and a material blocking plate. The material blocking plate is arranged one-to-one with the material discharge hole and is hinged to the material guide plate. The operating rod is arranged below the material blocking plate and abuts against the material blocking plate to block the material discharge hole. The operating rod penetrates the grain feeding layer and is movably arranged in the grain feeding layer along the length direction of the grain feeding layer.
[0009] Furthermore, the material blocking assembly includes a rotating rod, a material blocking plate, and an operating rod. The rotating rod is located below the material discharge hole and is rotatably connected to the grain feeding layer. The material blocking plate is located on the rotating rod and corresponds to each material discharge hole. The operating rod is located on the side of the material blocking plate away from the rotating rod and is movably connected to the grain feeding layer to drive the material blocking plate to rotate and block the material discharge hole. The end of the operating rod located on the outside of the grain feeding layer is also provided with a locking element for fixing the operating rod.
[0010] Furthermore, the feeder also includes a side guide plate with one end connected to the inner wall of the grain feeding layer and the other end inclined toward the feed guide plate. The side guide plate is arranged along the length of the grain feeding layer and is parallel to the feed guide plate in the grain feeding layer. The lower end of the side guide plate is provided with a horizontal plate extending outward, and the horizontal plate is provided with a grain feeding roller that is rotatably connected to the grain feeding layer. The side guide plate is evenly provided with discharge holes, and a baffle assembly for controlling the opening and closing of the discharge holes is provided below the discharge holes.
[0011] As a preferred embodiment, the grain-dispensing roller is provided with grain-dispensing plates arranged along the length of the grain-dispensing roller, and at least three grain-dispensing plates are evenly distributed on the grain-dispensing roller, with a grain-dispensing groove formed between two adjacent grain-dispensing plates and the grain-dispensing roller.
[0012] As a preferred embodiment, the grain-distributing roller is further provided with grain-distributing ring plates, which are spaced apart on the grain-distributing roller along its length.
[0013] The beneficial effects of this utility model are as follows: by opening a discharge hole on the guide plate and setting a baffle assembly below the discharge hole, the grain on the guide can be controlled to be discharged; when a large batch of grain is discharged to the grain dispensing layer, the baffle assembly is controlled to open the discharge hole to increase the grain discharge speed and prevent the grain from being blocked between the guide and the grain dispensing component; when the grain dispensing roller malfunctions and cannot discharge normally, the discharge hole can also be opened by controlling the baffle assembly to achieve emergency discharge, ensuring the normal discharge of the dried grain, preventing it from being blocked in the grain dispensing layer and being re-cooked by moisture, and ensuring the grain drying effect.

Detailed Implementation
[0020] The present invention will be further described below.
[0021] This utility model provides a grain dispensing mechanism for a grain dryer, mainly used for dispersing grain after it has been dried by the drying layer. It includes a grain dispensing component 2 and a grain separating component 3 arranged along the length of the grain dispensing layer 1. The grain dispensing component 2 includes a feed guide 21 and a grain dispensing roller 22. The feed guide 21 includes a guide plate 211 with an inverted V-shaped cross-section. The guide plate 211 includes a left guide plate 212 and a right guide plate 213. The left guide plate 212 and the right guide plate 213... The lower end is provided with a horizontal plate 215 extending outward in the horizontal direction. Above each horizontal plate 215 is a grain-dispensing roller 22 that is rotatably connected to the grain-dispensing layer 1. The left guide plate 212 and the right guide plate 213 are evenly provided with discharge holes 216. Below each discharge hole 216 is a baffle assembly 23 for controlling the opening and closing of the discharge hole 216. At least two sets of grain-dispensing assemblies 2 are evenly arranged in the grain-dispensing layer 1. The grain-separating component 3 is located above the two adjacent grain-dispensing rollers 22.
[0022] like Figures 1-3 As shown, the grain feeding mechanism of the grain dryer includes a grain feeding assembly 2 and a grain separating component 3 arranged along the length of the grain feeding layer 1. The grain separating component 3 can adopt the structure of the grain separating component 3 described in CN207922817U "A Grain Feeding Layer 1 for a Grain Dryer". The grain separating component 3 is used to initially disperse the grain after it has been dried by the drying layer of the grain dryer. The grain feeding assembly 2 includes a feeder 21 and a grain feeding roller 22. The feeder 21 includes a feeder plate 211 with an inverted V-shaped cross-section. The inverted V-shaped feeder plate 211 allows the grain dispersed from the grain separating component 3 to be dispersed a second time, preventing the grain from sticking together. The feeder plate 211 includes a left feeder plate 212 and a right feeder plate 213. The lower ends of the left feeder plate 212 and the right feeder plate 213 are provided with a horizontal plate 215 extending outward in the horizontal direction. Above the horizontal plate 215 is a... The design of the grain-dispensing roller 22 and the horizontal plate 215 creates a temporary storage area for the grain at the end of the feeder 21, increasing the contact time with the grain-dispensing roller 22 and improving the grain-dispensing efficiency. The left feeder plate 212 and right feeder plate 213 have evenly distributed discharge holes 216 along the length of the feeder plate 211. A baffle assembly 23 is installed below the discharge holes 216 to control the grain distribution from the feeder 21. When a large batch of grain is discharged to the grain-dispensing layer 1, the baffle assembly 23 opens the discharge holes 216 to increase the grain discharge speed and prevent grain from clogging between the feeder 21 and the grain-dispensing component 3. When the grain-dispensing roller 22 malfunctions and cannot discharge normally, the baffle assembly 23 can also be used to open the discharge holes 216 for emergency discharge, ensuring normal grain discharge after drying and preventing it from being blocked in the grain-dispensing layer 1 and being re-cooked by moisture, thus ensuring the grain drying effect.
[0023] As one specific embodiment, such as Figure 2As shown, the material blocking assembly includes an operating rod 231 that penetrates the grain feeding layer 1 and moves along the length of the grain feeding layer 1. A material blocking block 232, corresponding to a discharge hole 216, is fixed on the operating rod 231. The operator moves the operating rod 231 along the length of the grain feeding layer 1, thereby moving the material blocking blocks 232 on the operating rod 231, causing the material blocking blocks 232 to be misaligned with the discharge holes 216, thus opening the discharge holes 216 and allowing the grain accumulated on the guide plate 211 to fall from the discharge holes 216, preventing blockage. When it is not necessary to open the discharge holes 216... At 6 o'clock, simply move the operating lever 231 to make the baffle block 232 coincide with the discharge hole 216, thus blocking the discharge hole 216. This ensures that the grain on the guide plate 211 can only fall off via the grain-dispensing roller 22. Simultaneously, the degree of overlap between the baffle block 232 and the discharge hole 216 can be controlled to adjust the opening degree of the discharge hole 216, thereby controlling the speed at which the grain is released from the discharge hole 216. As a preferred method, to facilitate the operator's movement of the operating lever 231 and prevent excessive movement that could cause it to fall, such as... Figure 3 As shown, the operating lever 231 is provided with a limiting member 236 at one end outside the grain feeding layer 1 to restrict the movement of the operating lever 231, and an operating handle 237 is provided at the other end of the operating lever 231 away from the limiting member 236. The operating handle 237 is added to facilitate operation by the operator. The limiting member 236 is located at the end of the operating lever 231 away from the operating handle 237 to limit the range of movement of the operating handle 237 and prevent the operating lever 231 from slipping in the grain feeding layer 1. The limiting member 236 can be a nut or a stop with a diameter larger than the through hole opened in the grain feeding layer 1 for the operating lever 231 to pass through.
[0024] As another specific embodiment, such as Figure 4As shown, the material blocking assembly includes an operating rod 231 and a baffle plate 233. The baffle plate 233 is arranged one-to-one with the discharge hole 216 and is hinged to the guide plate 211. The operating rod 231 is located below the baffle plate 233 and abuts against the baffle plate 233 to block the discharge hole 216. The operating rod 231 penetrates the grain feeding layer 1 and is movably disposed within the grain feeding layer 1 along its length. Below the discharge hole 216 A baffle plate 233 is hinged to the guide plate 211, namely the left guide plate 212 and the right guide plate 213, so that the baffle plate 233 is rotatably connected to the left guide plate 212 and the right guide plate 213 to block the discharge hole 216. The operating rod 231 is movably disposed inside the grain feeding layer 1 and located below the baffle plate 233 to abut against the baffle plate 233, so that the baffle plate 233 blocks the discharge hole 216. When it is necessary to block the discharge hole 216, the operating rod 231 is inserted into the grain feeding layer 1 and abuts against the baffle plate 233; when it is necessary to open the discharge hole 216 to discharge material, the operating rod 231 is pulled away from the grain feeding layer 1, and the baffle plate 233 automatically rotates to a position away from the discharge hole 216 due to gravity, so as to open the discharge hole 216 to discharge material; however, this baffle assembly 23 cannot control the opening degree of the discharge hole 216, i.e. the discharge speed.
[0025] As another specific embodiment, such as Figure 5As shown, the material blocking assembly includes a rotating rod 235, a baffle plate 233, and an operating rod 231. The rotating rod 235 is located below the discharge hole 216 and is rotatably connected to the grain feeding layer 1. The baffle plate 233 is located on the rotating rod 235 and corresponds to the discharge hole 216 one by one. The operating rod 231 is located on the side of the baffle plate 233 away from the rotating rod 235 and is movably connected to the grain feeding layer 1 to drive the baffle plate 233 to rotate and block the discharge hole 216. The end of the operating rod 231 located on the outside of the grain feeding layer 1 is also provided with a locking element 238 for fixing the operating rod 231. The baffle plate 233 is rotatably connected to the grain feeding layer 1 through the rotating rod 235. The operating rod 231 drives the baffle plate 233 to rotate around the rotating rod 235 as an axis to block the discharge hole 216. In its natural state, the baffle plate 233 automatically rotates away from the discharge hole 216 under the action of gravity. The grain feeding speed is controlled by opening the feeding hole 216 for feeding. When the feeding hole 216 needs to be blocked, the operator slides the operating rod 231, causing the operating rod 231 to move along the arc-shaped groove 239 of the grain feeding layer 1. This drives the baffle plate 233 to rotate around the rotating rod 235, rotating the baffle plate 233 to a position that fits against the feeding hole 216, thus blocking the feeding hole 216. The position of the operating rod 231 is then fixed by the locking part 238 set on the operating rod 231 to prevent the operating rod 231 from shifting due to equipment vibration, i.e., the baffle plate 233 from shifting. The rotation angle of the baffle plate 233, i.e., the angle between the baffle plate 233 and the feeding hole 216, is controlled by controlling the sliding angle of the operating rod 231, thereby controlling the feeding speed of the grain. The locking part 238 can be a nut, a buckle, or a clamp to fix the operating rod 231.
[0026] To avoid dead zones in the grain feeding layer 1, which could cause the grain to fall into the discharge port without being properly dispersed, such as... Figure 1As shown, the feeder 21 further includes a side guide plate 214 with one end connected to the inner wall of the grain feeding layer 1 and the other end inclined toward the feed guide plate 211. The side guide plate 214 is arranged along the length of the grain feeding layer 1 and parallel to the feed guide plate 211 within the grain feeding layer 1. The lower end of the side guide plate 214 is provided with a horizontally extending outward plate 215, and the horizontal plate 215 is provided with a grain feeding roller 22 rotatably connected to the grain feeding layer 1. The side guide plate 214 is provided with uniformly spaced discharge holes 216, and below the discharge holes 216 is a control for discharging. The baffle assembly 23 for opening and closing the feed hole 216; by adding a side guide plate 214 that is connected to the inner wall of the grain feeding layer 1, and the side guide plate 214 is inclinedly arranged in the grain feeding layer 1, the grain sliding down the inner wall of the grain feeding layer 1 can be dispersed by the side guide plate 214, and then dispersed by the grain feeding roller 22 arranged on the horizontal plate 215 at the lower end of the side guide plate 214; furthermore, the side guide plate 214 is also provided with a feed hole 216 and a baffle assembly 23 to control the grain feeding at the side guide plate 214, and control the feeding speed according to different quantities of grain.
[0027] Furthermore, to enable the grain-distributing roller 22 to better disperse the grain and prevent sticking, such as... Figure 1 , Figure 2 As shown, the grain-distributing roller 22 is provided with grain-distributing plates 221 arranged along the length of the grain-distributing roller 22. At least three grain-distributing plates 221 are evenly distributed on the grain-distributing roller 22, and grain-distributing grooves 222 are formed between two adjacent grain-distributing plates 221 and the grain-distributing roller 22. By arranging grain-distributing plates 221 on the grain-distributing roller 22, grain-distributing grooves 222 are formed between adjacent grain-distributing plates 221. Each grain-distributing groove 222 can hold a certain amount of grain, and the rotation of the grain-distributing roller 22 generates directional thrust to ensure that the grain is conveyed along a predetermined path, greatly reducing the disorderly slippage of grain grains on the roller surface. Moreover, the holding capacity of the grain-distributing grooves 222 can prevent grain flow overload or interruption, ensuring the grain feeding speed. The consistent degree and amount of material feeding improve overall processing efficiency. As a preferred method, the grain-distributing roller 22 is also provided with a grain-distributing ring plate 223, which is spaced along the length of the grain-distributing roller 22. By adding the grain-distributing ring plate 223, the grain-distributing roller 22 can cut into the clump of grain during operation and disperse it into a loose state, further ensuring the degree of grain dispersion. In addition, the addition of the grain-distributing ring plate 223 along the length of the grain-distributing roller 22 is equivalent to adding a ring-shaped reinforcing rib to the surface of the roller body, improving the bending stiffness of the grain-distributing roller 22, making it suitable for processing high-humidity or high-viscosity grains, and effectively preventing the roller body from deforming due to uneven force.
