Description

Technical Field

[0001] The invention relates to the technical field of grain sucking machines, and in particular to a vehicle-mounted grain sucking machine. Background Art

[0002] In the fields of agriculture and logistics, grain handling and transportation has always been an important link. Although traditional grain suckers have improved the efficiency of grain handling to a certain extent, their fixedness and inconvenience in movement limit their scope of application. In order to overcome this problem, vehicle-mounted grain suckers came into being. Vehicle-mounted grain suckers load the main body of the grain sucker through a conveyor vehicle, which not only realizes the convenient movement of the equipment, but also facilitates the movement of the loaded materials, greatly improving the flexibility and efficiency of grain handling.

[0003] However, the existing vehicle-mounted grain suckers still have certain problems and challenges in technology and application, among which the most prominent are the limitations of the two methods of pneumatic grain sucking and spiral blade grain sucking.

[0004] Pneumatic grain suction performs well in preventing dust. It uses the negative pressure principle to suck grain into the equipment, effectively reducing dust pollution during grain handling. However, the pneumatic force of pneumatic grain suction is limited. Especially after the grain suction pipe is inserted deep into the pile, the air cannot smoothly enter the suction pipe, resulting in a greatly reduced grain suction effect. It may even cause the pipe to be blocked due to the inability to feed grain. In severe cases, this situation may also cause damage to the fan and affect the normal operation of the equipment. Especially in vehicle-mounted grain suction machines, since the fan is usually driven by the vehicle's engine and has relatively low power, the problem of being unable to feed grain due to the grain suction pipe being inserted deep into the pile is more prominent.

[0005] In contrast, the spiral blade suction method transports materials through the rotation of the spiral blade. This method does not affect normal work after being inserted deep into the pile of materials, and can continuously and stably transport grain. However, the spiral blade suction method is prone to generate dust when conveying materials, which not only affects the cleanliness of the working environment, but also may threaten the health of operators.

[0006] In view of the above problems, the design and application of vehicle-mounted grain suction machines need to be continuously improved and innovated. On the one hand, it is necessary to optimize the pneumatic grain suction and the design of the grain suction pipe to ensure that the grain suction effect can be maintained after being inserted deep into the pile and to prevent the fan from being damaged due to the inability of air to enter. On the other hand, it is necessary to improve the dust prevention measures of the spiral blade grain suction to reduce the generation of dust.

[0007] Therefore, a vehicle-mounted grain suction machine is needed to overcome the occurrence of the above problems. Summary of the invention

[0008] In order to solve the above problems, an embodiment of the present invention provides a vehicle-mounted grain suction machine, which achieves the purpose of solving the problems raised in the background technology.

[0009] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: a vehicle-mounted grain suction machine, comprising a vehicle body and a silo arranged on the vehicle body, wherein the silo is provided with a feeding device for conveying materials; The feeding device comprises a negative pressure feeding component arranged on the silo and a spiral feeding component arranged on the silo; The negative pressure material conveying assembly includes a feed pipe connected to the silo, a negative pressure fan installed on the vehicle body, and a connecting pipe installed at the air inlet of the negative pressure fan and connected to the silo; The spiral feeding assembly includes a feed pipe 2 arranged inside the feed pipe 1, a connecting shaft rotatably arranged on the silo, a spiral blade fixedly connected to the outside of the connecting shaft and rotatably arranged inside the feed pipe 2, a feeding part fixedly connected to one end of the feed pipe 2, and a feeding part fixedly connected to the other end of the feed pipe 2; A distance is provided between the inner wall of the first feeding pipe and the outer wall of the second feeding pipe.

[0010] As a further improvement of the above technical solution: The spiral feeding assembly also includes a temporary storage bin fixedly connected to the interior of the silo, a baffle hingedly arranged at the bottom opening of the temporary storage bin, and a spring support rod hingedly arranged between the bottom of the baffle and the inner wall of the silo; The unloading portion is located inside the temporary storage bin, and one end of the second feeding pipe is connected and arranged on the temporary storage bin.

[0011] The vehicle body is provided with a driving source for driving the negative pressure fan to operate and the connecting shaft to rotate; a transmission assembly is provided between the driving source and the negative pressure fan and between the driving source and the connecting shaft.

[0012] The transmission assembly includes a pulley 1 fixedly connected to the output end of the driving source, a pulley 2 fixedly connected to the input end of the negative pressure fan, a pulley 3 fixedly connected to the connecting shaft, a belt 1 arranged between the pulley 1 and the pulley 2, and a belt 2 arranged between the pulley 1 and the pulley 3.

[0013] A tensioning assembly for tensioning belt one and / or belt two is arranged on the side of the silo.

[0014] The tensioning assembly includes an adjusting bin arranged on the side of the silo, a guide groove opened inside the adjusting bin, a positioning hole one arranged inside the guide groove, a positioning hole two arranged inside the guide groove, a positioning hole three arranged inside the guide groove, a positioning hole four arranged inside the guide groove, a connecting rod slidably arranged inside the guide groove, and a tensioning wheel rotatably arranged outside the connecting rod.

[0015] Two tension wheels are provided, one of which is connected to belt one, and the other is connected to belt two.

[0016] The sides of the first positioning hole, the second positioning hole, the third positioning hole and the fourth positioning hole are all provided with card slots, and the ends of the connecting rods are fixedly connected with card blocks used in conjunction with the card slots.

[0017] The vehicle body is provided with a dust removal mechanism connected to the connecting pipe.

[0018] A connecting piece for connecting the first feeding pipe and the second feeding pipe is arranged inside the spacing, and the length direction of the connecting piece is parallel to the axial direction of the first feeding pipe.

[0019] The beneficial effects of the embodiments of the present invention are: In actual use, since the feeding part is protruding from the end of the feed pipe 1, when in use, the feeding part is inserted into the interior of the material pile, at this time, the feed pipe 1 is difficult to enter the deep of the material pile, which can prevent the problem that the feed pipe 1 cannot absorb grain; even if the feed pipe 1 is still inserted into the deep of the material pile after the feeding part is inserted into the interior of the material pile, the spiral blades continue to convey the material, so that the insertion position of the feeding part is depressed, which can make the height of the material pile at one place of the feed pipe continue to decrease. When the material pile at one place of the feed pipe is reduced to a certain height, the feed pipe 1 can still absorb the material normally, preventing the negative pressure fan from being damaged after the feed pipe 1 does not take in air for a long time; that is, in the present application, by combining the two methods of spiral feeding and pneumatic feeding, the problem of spiral feeding easily generating dust is solved, and the problem of pneumatic feeding easily clogging is solved; In actual use, the material transported by the feed pipe 2 first enters the interior of the temporary storage bin. As the material inside the temporary storage bin gradually increases, its weight overcomes the elastic force provided by the spring support rod, causing the baffle to open, allowing the material inside the temporary storage bin to flow out, that is, allowing the material to enter the interior of the bin, that is, the intermittent opening of the temporary storage bin is achieved through the spring support rod and the baffle; through the intermittent opening of the temporary storage bin, first of all, it can prevent air from continuously entering the interior of the bin through the feed pipe 2, causing the negative pressure inside the feed pipe 1 to decrease, affecting the suction operation of the feed pipe 1; at the same time, through the intermittent opening of the temporary storage bin, when the mouth of the feed pipe 1 is After the blockage occurs, the pressure inside the silo can be balanced by intermittently opening the temporary storage bin to prevent the negative pressure fan from being damaged due to long-term poor air intake. In addition, the intermittent opening of the temporary storage bin can intermittently generate negative pressure inside the feed pipe 2, which is convenient for quickly sucking the dust inside the feed pipe 2 into the silo to prevent the dust inside the feed pipe 2 from floating out. Finally, the intermittent opening of the temporary storage bin generates a pressure difference between the interior of the temporary storage bin and the interior of the silo. When the temporary storage bin is opened, the pressure difference can prompt the material inside the temporary storage bin to quickly enter the interior of the silo, which is convenient for the rapid discharge of the material after the temporary storage bin is opened. In actual use, the tensioning component can be used to tension the belt one and / or the belt two, so that the tensioning component can be used to select three feeding operation modes: operating the negative pressure feeding component alone, operating the spiral feeding component alone, and operating the negative pressure feeding component and the spiral feeding component at the same time; the user can select according to the actual situation, which is convenient for actual use; When switching the three feeding operation modes of operating the negative pressure feeding component alone, operating the spiral feeding component alone, and operating both the negative pressure feeding component and the spiral feeding component at the same time through the tensioning component, since the feed pipe one and the feed pipe two are arranged in one body, the user only needs to take the feed pipe one to use, that is, taking the feed pipe one to use can correspond to the three feeding operation modes, thereby preventing taking errors.

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] See also Figures 1 to 8 The embodiment of the present invention discloses a vehicle-mounted grain sucking machine, comprising a vehicle body 1, a silo 2 arranged on the vehicle body 1, and a feeding device 3 for conveying materials is arranged on the silo 2; The feeding device 3 includes a negative pressure feeding component 4 arranged on the silo 2 and a spiral feeding component 5 arranged on the silo 2; In actual use, the negative pressure feeding component 4 and the spiral feeding component 5 are used to transport the material to the interior of the silo 2; The negative pressure material conveying assembly 4 includes a feed pipe 41 connected to the silo 2, a negative pressure fan 42 installed on the vehicle body 1, and a connecting pipe 43 installed at the air inlet of the negative pressure fan 42 and connected to the silo 2; After the negative pressure fan 42 is running, negative pressure is generated inside the connecting pipe 43, that is, negative pressure is generated inside the silo 2, so that the feed pipe 1 41 can suck the material into the silo 2; The spiral feeding assembly 5 includes a feed pipe 2 51 arranged inside the feed pipe 1 41, a connecting shaft 52 rotatably arranged on the silo 2, a spiral blade 53 fixedly connected to the outside of the connecting shaft 52 and rotatably arranged inside the feed pipe 2 51, a lowering portion 54 fixedly connected to one end of the feed pipe 2 51, and a feeding portion 58 fixedly connected to the other end of the feed pipe 2 51; the connecting shaft 52 rotates to drive the spiral blade 53 to rotate, and after the feeding portion 58 is inserted into the material pile, the material can be transported along the feed pipe 2 51 by the rotation of the spiral blade 53, and the material falls into the interior of the silo 2 when it moves to the lowering portion 54; the feeding portion 58 is protruding from the end of the feed pipe 1 41; a rotating shaft is arranged inside the feeding portion 58, and one end of the spiral blade 53 is fixedly connected to the rotating shaft; the feed pipe 1 41 and the feed pipe 2 51 are both hoses; In actual use, the feeding part 58 is inserted into the interior of the material pile, and the material can be transported by the rotation of the spiral blades 53. When dust is generated in the material, the dust can be sucked in time through the feeding pipe 41 to prevent the dust from further spreading and causing pollution; in actual use, since the feeding part 58 is protruding from the end of the feeding pipe 41, the feeding part 58 is inserted into the interior of the material pile during use. At this time, it is difficult for the feeding pipe 41 to enter the depth of the material pile, which can prevent the problem that the feeding pipe 41 cannot absorb grain; even after the feeding part 58 is inserted into the interior of the material pile, the feeding pipe 41 is still inserted into the depth of the material pile, because the spiral blades 53 continue to transport the material, the insertion position of the feeding part 58 is depressed, which can make the height of the material pile at the feeding pipe 41 continue to decrease. When the material pile at the feeding pipe 41 is reduced to a certain height, the feeding pipe 41 can still absorb the material normally, preventing the negative pressure fan 42 from being damaged after the feeding pipe 41 does not take in air for a long time; That is, in the present application, by combining the two modes of spiral feeding and pneumatic feeding, the problem of spiral feeding being prone to dust generation is solved, and the problem of pneumatic feeding being prone to blockage is solved; A gap 6 is provided between the inner wall of the first feed pipe 41 and the outer wall of the second feed pipe 51; By setting the interval 6, the material and air can pass through the inside of the feed pipe 1 41 normally, preventing the feed pipe 1 41 and the feed pipe 2 51 from being attached to each other and affecting the transportation of the material.

[0024] As a further illustration of this application: The screw feeding assembly 5 also includes a temporary storage bin 55 fixedly connected to the interior of the silo 2, a baffle 56 hingedly arranged at the bottom opening of the temporary storage bin 55, and a spring support rod 57 hingedly arranged between the bottom of the baffle 56 and the inner wall of the silo 2; The material discharge portion 54 is located inside the temporary storage bin 55, and one end of the feed pipe 51 is connected to the temporary storage bin 55; In actual use, the material transported by the feed pipe 2 51 first enters the interior of the temporary storage bin 55. As the material inside the temporary storage bin 55 gradually increases, its weight overcomes the elastic force provided by the spring support rod 57, so that the baffle 56 is opened, and the material inside the temporary storage bin 55 can flow out, that is, the material enters the interior of the silo 2, that is, the intermittent opening of the temporary storage bin 55 is achieved by the spring support rod 57 and the baffle 56; By intermittently opening the temporary storage bin 55, firstly, it is possible to prevent air from continuously entering the interior of the silo 2 through the feed pipe 2 51, thereby reducing the negative pressure inside the feed pipe 1 41 and affecting the suction operation of the feed pipe 1 41; At the same time, by intermittently opening the temporary storage bin 55, when the pipe opening of the feed pipe 41 is blocked, the pressure inside the silo 2 can be balanced by intermittently opening the temporary storage bin 55 to prevent the negative pressure fan 42 from being damaged due to long-term poor air intake; In addition, by intermittently opening the temporary storage bin 55, negative pressure can be intermittently generated inside the second feed pipe 51, so that the dust inside the second feed pipe 51 can be quickly sucked into the interior of the silo 2, preventing the dust inside the second feed pipe 51 from floating out; Finally, by intermittently opening the temporary storage bin 55, a pressure difference is generated between the interior of the temporary storage bin 55 and the interior of the silo 2. When the temporary storage bin 55 is opened, the pressure difference can cause the material inside the temporary storage bin 55 to quickly enter the interior of the silo 2, thereby facilitating the rapid discharge of the material after the temporary storage bin 55 is opened.

[0025] As a further illustration of this application: The vehicle body 1 is provided with a driving source 8 for driving the negative pressure fan 42 to operate and the connecting shaft 52 to rotate; a transmission assembly 9 is provided between the driving source 8 and the negative pressure fan 42 and between the driving source 8 and the connecting shaft 52; In actual use, the driving source 8 drives the negative pressure fan 42 to operate and drives the connecting shaft 52 to rotate through the transmission assembly 9; The driving source 8 may be an engine of the vehicle body 1 itself, an engine that can be mounted on the vehicle, or the like.

[0026] As a further illustration of this application: The transmission assembly 9 includes a pulley 1 91 fixedly connected to the output end of the driving source 8, a pulley 2 92 fixedly connected to the input end of the negative pressure fan 42, a pulley 3 93 fixedly connected to the connecting shaft 52, a belt 1 94 arranged between the pulley 1 91 and the pulley 2 92, and a belt 2 95 arranged between the pulley 1 91 and the pulley 3 93; After the driving source 8 is started, it drives the pulley 1 91 to rotate, thereby driving the pulley 2 92 to rotate through the belt 1 94, and driving the pulley 3 93 to rotate through the belt 2 95.

[0027] As a further illustration of this application: A tensioning assembly 7 for tensioning belt 1 94 and / or belt 2 95 is provided on the side of the silo 2; In actual use, the tensioning component 7 can be used to tension the belt 1 94 and / or the belt 2 95, so that the tensioning component 7 can be used to select three feeding operation modes: operating the negative pressure feeding component 4 alone, operating the spiral feeding component 5 alone, and operating the negative pressure feeding component 4 and the spiral feeding component 5 at the same time; the user can choose according to the actual situation, which is convenient for actual use; Specifically: When the tensioning assembly 7 tensions the belt 1 94 alone, the pulley 1 91 can drive the pulley 2 92 to rotate through the belt 1 94, while the pulley 1 91 cannot drive the pulley 3 93 to rotate through the loose belt 2 95, thereby driving the negative pressure fan 42 to operate, that is, operating the negative pressure feeding assembly 4 alone to perform feeding operation; When the tensioning assembly 7 tensions the belt 2 95 alone, the pulley 1 91 can drive the pulley 3 93 to rotate through the belt 2 95, and the pulley 1 91 cannot drive the pulley 2 92 to rotate through the loose belt 1 94, so the connecting shaft 52 can be driven to rotate, that is, the spiral feeding assembly 5 is operated alone to perform feeding operation; When the tensioning assembly 7 tensions the belt 1 94 and the belt 2 95 at the same time, the pulley 1 91 drives the pulley 2 92 to rotate through the belt 1 94, and drives the pulley 3 93 to rotate through the belt 2 95, so that the negative pressure fan 42 can be driven to operate while driving the connecting shaft 52 to rotate, so that the negative pressure feeding assembly 4 and the spiral feeding assembly 5 can be operated at the same time to perform feeding operations.

[0028] As a further illustration of this application: When switching the three feeding operation modes of operating the negative pressure feeding component 4 alone, operating the spiral feeding component 5 alone, and operating both the negative pressure feeding component 4 and the spiral feeding component 5 simultaneously through the tensioning component 7, since the feed pipe 1 41 and the feed pipe 2 51 are integrally arranged, the user only needs to take the feed pipe 1 41 for use, that is, taking the feed pipe 1 41 for use can correspond to the three feeding operation modes, thereby preventing taking errors.

[0029] As a further illustration of this application: The tensioning assembly 7 includes an adjusting bin 71 arranged at the side of the silo 2, a guide groove 72 opened inside the adjusting bin 71, a positioning hole 1 73 arranged inside the guide groove 72, a positioning hole 2 74 arranged inside the guide groove 72, a positioning hole 3 75 arranged inside the guide groove 72, a positioning hole 4 76 arranged inside the guide groove 72, a connecting rod 77 slidably arranged inside the guide groove 72, and a tensioning wheel 78 rotatably arranged outside the connecting rod 77; The connecting rod 77 can slide inside the guide groove 72, and the belt 1 94 and / or the belt 2 95 can be tensioned by the tensioning wheel 78 by inserting and fixing the connecting rod 77 into different positioning holes; Specifically: When the connecting rod 77 is inserted into the interior of the positioning hole 1 73, the tensioning wheel 78 tensions the belt 1 94, while the tensioning wheel 78 cannot tension the belt 2 95; that is, at this time, the pulley 1 91 can drive the pulley 2 92 to rotate through the belt 1 94, that is, the negative pressure feeding assembly 4 is operated alone to perform the feeding operation; When the connecting rod 77 is inserted into the second positioning hole 74, the tensioning wheel 78 tensions the second belt 95, while the tensioning wheel 78 cannot tension the first belt 94; that is, the first pulley 91 can drive the third pulley 93 to rotate through the second belt 95, that is, the spiral feeding assembly 5 is operated alone to perform feeding operation; When the connecting rod 77 is inserted into the interior of the positioning hole 3 75, the tensioning wheel 78 tensions the belt 1 94 and the belt 2 95 at the same time, that is, the pulley 1 91 can drive the pulley 2 92 to rotate through the belt 1 94, and can drive the pulley 3 93 to rotate through the belt 2 95, that is, the negative pressure feeding component 4 and the spiral feeding component 5 are operated at the same time to perform feeding operation; When the connecting rod 77 is inserted into the interior of the positioning hole four 76, the tensioning wheel 78 cannot tension the belt one 94 and the belt two 95, that is, the belt one 94 and the belt two 95 are both in a relaxed state. At this time, the driving source 8 can be inspected and repaired, the belt one 94 can be replaced and maintained, and the belt one 94 can be replaced and maintained.

[0030] As a further illustration of this application: Two tension wheels 78 are provided, one of which is connected to belt 1 94 and the other is connected to belt 2 95; In actual use, when the tensioning wheel 78 tensions belt 1 94 and belt 2 95 at the same time, that is, at this time, pulley 1 91 can drive pulley 2 92 to rotate through belt 1 94, and can drive pulley 3 93 to rotate through belt 2 95; although belt 1 94 and belt 2 95 drive the tensioning wheel 78 to rotate in the same direction, due to the different running resistances of the negative pressure fan 42 and the connecting shaft 52, there is a speed difference between belt 1 94 and belt 2 95. When a single tensioning wheel 78 is used to tension belt 1 94 and belt 2 95 at the same time, it is easy to cause a speed difference between the belt and the tensioning wheel 78, which aggravates the wear of the belt; therefore, two independent tensioning wheels 78 are used in the present application to tension belt 1 94 and belt 2 95 respectively to avoid aggravated wear due to the speed difference.

[0031] As a further illustration of this application: The sides of the first positioning hole 73, the second positioning hole 74, the third positioning hole 75 and the fourth positioning hole 76 are all provided with a card slot 79, and the end of the connecting rod 77 is fixedly connected with a card block 710 used in conjunction with the card slot 79; In actual use, after the connecting rod 77 is inserted into the interior of the positioning hole, the connecting rod 77 is rotated so that the clamping block 710 is clamped into the interior of the clamping slot 79 to complete the fixation.

[0032] As a further illustration of this application: The vehicle body 1 is provided with a dust removal mechanism 11 connected to the connecting pipe 43 to prevent sundries such as materials and dust from entering the negative pressure fan 42 .

[0033] As a further illustration of this application: A connecting piece 10 for connecting feed pipe 1 41 and feed pipe 2 51 is provided inside the spacing 6, and the length direction of the connecting piece 10 is parallel to the axial direction of feed pipe 1 41; the spacing 6 between feed pipe 1 41 and feed pipe 2 51 is maintained by the connecting piece 10; in actual use, using a connecting piece 10 with a smaller thickness can reduce the influence of the connecting piece 10 on the air circulation inside feed pipe 1 41.
