Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a blowing and feeding mechanism for a bean harvester. Background Technology

[0002] In agricultural production, mature beans grow on bean stalks, and the beans are covered with a shell. The beans are squeezed out of the pods. Using a harvester to harvest beans greatly improves work efficiency.

[0003] Utility model patent application number CN202321549414.0 discloses a soybean harvester, including a chassis assembly, a driving component mounted on the lower end of the chassis assembly, a harvesting device located on the outside of the chassis assembly, a driver's cab located on the upper front side of the chassis assembly, a collecting device located at the upper end of the chassis assembly, a threshing device located above the collecting device, and the harvesting device and the threshing device connected. A vibrating screen is installed inside the collecting device, and a speed regulating device is located on one side of the threshing device. The grains and impurities screened by the vibrating screen fall evenly into the cleaning chamber, and a fan blows the impurities out of the grain chamber, resulting in a low impurity rate. The grains fall into the grain collection box in the grain chamber and are transported by a grain auger to the grain lifting auger. The grain lifting auger transports the grains with low impurity content to the grain bin, while the grains with high impurity content enter the grain collection box in the impurity chamber and are transported by an impurity auger to the impurity lifting auger. The impurity lifting auger transports the grains with high impurity content back to the cleaning chamber for cleaning. However, during the grain transport process by the grain auger and the grain lifting auger, the rapidly rotating auger can cause some grains to break, affecting the quality of the grains. In addition, some impurities that affect the quality of the grains still remain in the grains with low impurity content. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a bean harvester blowing and feeding mechanism with reasonable structure and good cleaning effect, which can avoid damage to some of the grains caused by the rotating auger, and can further clean the impurities in the grains.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A bean harvester blowing and feeding mechanism includes a chassis assembly, on which a cleaning chamber and a grain bin are fixedly connected. The cleaning chamber has a grain chamber, and a belt feeding device is installed at the position of the grain chamber in the cleaning chamber. A conveyor box assembly is installed on one side of the cleaning chamber. One end of the belt feeding device extends into the interior of the conveyor box assembly. An air supply device is installed at one end of the conveyor box assembly, and the other end of the conveyor box assembly is connected to the grain bin through a conveying pipe.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The conveyor box assembly includes a conveyor box, which is fixedly connected to the chassis assembly. A partition is fixedly connected inside the conveyor box, which divides the inner cavity of the conveyor box into a material conveying chamber and an air supply chamber. The partition is inclined.

[0009] Further optimization: The conveyor box has a feed inlet on the side near the cleaning chamber, and the end of the belt feeding device away from the cleaning chamber passes through the feed inlet and extends into the conveying chamber.

[0010] Further optimization: An air outlet is provided at one end of the conveyor box near the air supply device, and the air outlet is set in accordance with the air supply device. A discharge pipe is fixedly connected to one end of the conveyor box near the air supply device. The conveying pipe and the discharge pipe are fixedly connected. Both the air outlet and the discharge pipe are connected to the air supply chamber.

[0011] Further optimization: A cleaning device is installed between the conveying pipe and the grain silo, and the cleaning device is located near the top of the grain silo.

[0012] Further optimization: The impurity removal device includes an impurity removal box, which is fixedly connected to the chassis assembly. A baffle mesh is fixedly connected inside the impurity removal box, which divides the inner cavity of the impurity removal box into an impurity removal chamber and a debris chamber.

[0013] Further optimization: One end of the impurity removal box is fixedly connected to the feed pipe, which is connected to the impurity removal chamber, and the other end of the feed pipe is connected to the conveying pipe.

[0014] Further optimization: A discharge hopper is fixed to the side of the impurity removal box near the grain silo. The discharge hopper is connected to the impurity removal chamber, and the end of the discharge hopper away from the impurity removal box extends into the grain silo.

[0015] Further optimization: The lower part of the impurity removal chamber is provided with a first material guide frame and a second material guide frame. The first material guide frame and the second material guide frame are respectively located on both sides of the discharge hopper and are fixedly connected to the impurity removal box. A baffle is provided between the material blocking net and the second material guide frame.

[0016] Further optimization: A discharge port is provided at the end of the impurity removal box away from the feed pipe, and the discharge port is connected to the impurity chamber.

[0017] This invention replaces the grain auger with a belt conveyor to transport grains to the conveyor box assembly. Air from the air supply device then transports the grains from the conveyor box assembly to the grain silo via a conveying pipe. This replaces the traditional grain lifting auger, preventing damage to some grains caused by auger rotation and improving grain quality. Grains with low impurity content are blown into the impurity removal box through the conveying pipe. Small impurities pass through the baffle mesh into the impurity chamber and are discharged from the impurity outlet. The grains, blocked by the baffle mesh, fall back into the impurity removal chamber and collect at the discharge hopper before entering the grain silo. A secondary impurity removal process further improves the impurity removal effect, ensuring the quality of the grains entering the grain silo.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] like Figure 1-6 As shown, a bean harvester blowing and feeding mechanism includes a chassis assembly, on which a cleaning chamber and a grain bin are fixedly connected. The cleaning chamber is provided with a grain chamber and a waste chamber.

[0027] A belt feeding device 1 is installed in the grain chamber of the cleaning chamber, and a conveyor box assembly 2 is installed on one side of the cleaning chamber. One end of the belt feeding device 1 extends into the interior of the conveyor box assembly 2. Both the belt feeding device 1 and the conveyor box assembly 2 are fixedly connected to the chassis assembly.

[0028] This design uses a belt feeder 1 to transport grains instead of a grain auger, avoiding damage to some grains caused by the rotation of the auger and improving the quality of the grains.

[0029] A protective cover is provided between the cleaning chamber and the conveyor box assembly 2 to ensure that the belt feeding device 1 transports the grains in the cleaning chamber to the conveyor box assembly 2.

[0030] The belt feeding device 1 includes two support plates 101 arranged in parallel at a certain distance. The two support plates 101 are fixedly connected by a plurality of first connecting plates 105. A drive roller 102 and a driven roller 103 rotate between the two support plates 101. A belt 104 is connected between the drive roller 102 and the driven roller 103. The drive roller 102 is connected to the power unit of the harvester.

[0031] A support plate 106 for supporting the belt 104 is fixed above a plurality of first connecting plates 105, thereby improving the conveying capacity of the belt 104.

[0032] One end of the conveyor box assembly 2 is equipped with an air supply device 3, and the other end of the conveyor box assembly 2 is connected to the grain silo through a material conveying pipe 4.

[0033] With this design, the air blown out by the air supply device 3 transports the grains in the conveying box assembly 2 to the grain bin through the conveying pipe 4, replacing the grain lifting auger to transport the grains. This avoids the damage to some grains caused by the rotation of the auger and further improves the quality of the grains.

[0034] The conveyor box assembly 2 includes a conveyor box 201, which is fixedly connected to the chassis assembly. A partition 202 is fixedly connected inside the conveyor box 201, which divides the inner cavity of the conveyor box 201 into a material conveying chamber 203 and an air supply chamber 204. The partition 202 is inclined to facilitate the grains in the material conveying chamber 203 to slide into the air supply chamber 204.

[0035] The conveyor box 201 has a feed inlet 2011 on the side near the cleaning chamber, and the belt feeder 1, the end away from the cleaning chamber, passes through the feed inlet 2011 and extends into the conveying chamber 203.

[0036] An air outlet 2012 is provided at one end of the conveying box 201 near the air supply device 3. The air outlet 2012 is correspondingly provided with the air supply device 3. A discharge pipe 205 is fixedly connected to one end of the conveying box 201 near the air supply device 3. The conveying pipe 4 is fixedly connected to the discharge pipe 205. Both the air outlet 2012 and the discharge pipe 205 are connected to the air supply chamber 204.

[0037] With this design, the grains enter the conveying chamber 203 from the feed inlet 2011. The grains in the conveying chamber 203 slide down the partition 202 into the air supply chamber 204. The air blown out by the air supply device 3 enters the air supply chamber 204 from the air supply port 2012, and then blows the grains to the discharge pipe 205. The grains are then blown into the grain bin along the conveying pipe 4. The partition 202 guides the air blown into the conveying box 201, preventing the air from blowing into the conveying chamber 203 and affecting the grains on the belt conveyor 1 falling into the conveying box 201.

[0038] The air supply device 3 includes a hair dryer.

[0039] The feed pipe 4 is a flexible hose, preferably made of rubber steel wire.

[0040] A cleaning device 5 is installed between the conveying pipe 4 and the grain silo, and the cleaning device 5 is located near the top of the grain silo.

[0041] This design allows for the initial impurity removal of grains in the cleaning chamber, followed by a second impurity removal process using the impurity removal device 5 for grains with low impurity content. This further improves the impurity removal effect and ensures the quality of grains entering the grain warehouse.

[0042] The impurity removal device 5 includes an impurity removal box 501, which is fixedly connected to the chassis assembly. Inside the impurity removal box 501, a baffle net 503 is fixedly connected by multiple second connecting plates 502. The baffle net 503 divides the inner cavity of the impurity removal box 501 into an impurity removal cavity 504 and a debris cavity 505.

[0043] With this design, some impurities are still mixed in with the grains blown into the impurity removal box 501 from the conveying pipe 4. Some small impurities pass through the baffle net 503 and enter the impurity chamber 505, and then are discharged from the impurity removal box 501. The grains are blocked by the baffle net 503 and remain in the impurity removal chamber 504, and then enter the grain bin, thus realizing secondary impurity removal of the grains. Since the size of beans such as peas, soybeans, and mung beans is different, baffle nets 503 with different mesh sizes can be installed according to the size of the beans, thereby achieving a better impurity removal effect.

[0044] One end of the impurity removal box 501 is fixedly connected to the feed pipe 508, which is connected to the impurity removal chamber 504. The other end of the feed pipe 508 is connected to the conveying pipe 4, so that the grains in the conveying pipe 4 can easily enter the impurity removal chamber 504.

[0045] A discharge hopper 509 is fixedly connected to the side of the impurity removal box 501 near the grain silo. The discharge hopper 509 is connected to the impurity removal chamber 504. The end of the discharge hopper 509 away from the impurity removal box 501 extends into the grain silo, so that the grains in the impurity removal chamber 504 can easily enter the grain silo.

[0046] The lower part of the impurity removal chamber 504 is provided with a first material guide 506 and a second material guide 507. The first material guide 506 and the second material guide 507 are respectively located on both sides of the discharge hopper 509 and are fixedly connected to the impurity removal box 501.

[0047] The top plates of the first feeder 506 and the second feeder 507 are both inclined, which facilitates the collection of grains into the discharge hopper 509 for discharge.

[0048] A baffle 510 is provided between the material blocking net 503 and the second material feeding frame 507. The baffle 510 is fixedly connected to the material blocking net 503. The baffle 510 effectively blocks the grains, causing them to fall back to the discharge hopper 509 for discharge.

[0049] Rubber sheets are preferred for baffle 510.

[0050] The end of the impurity removal box 501 away from the feed pipe 508 is provided with a discharge port 5011, which is connected to the impurity chamber 505, so as to facilitate the discharge of impurities from the impurity removal box 501.

[0051] With this design, grains with low impurity content are blown into the impurity removal box 501 from the conveying pipe 4. Small impurities pass through the baffle net 503 and enter the impurity chamber 505, and are discharged from the impurity discharge port 5011. The grains are blocked by the baffle net 503 and fall back into the impurity removal chamber 504, and are collected at the discharge hopper 509 and enter the grain bin.

[0052] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
