Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a self-propelled straw harvesting and granulating machine. Background Technology

[0002] In rural areas, a large amount of crop straw is left in the fields during the autumn harvest season. To avoid affecting the planting of crops the following spring, people usually burn the straw as the most direct way to dispose of it. However, this method wastes resources and pollutes the environment. At present, direct burning of straw has been restricted, and straw recycling and reuse are encouraged.

[0003] Currently, my country produces a massive amount of straw annually; corn stalks alone can generate over 5 tons per hectare. Despite the large quantity, the utilization rate is extremely low. A significant portion is disposed of through open burning, causing substantial environmental pollution. Existing straw collection equipment mainly consists of round balers, which, along with the bales they produce, have the following drawbacks:

[0004] 1. The waste was not completely collected, and a considerable amount remained. Workers needed to clean it a second time before burning it directly.

[0005] 2. After collection, round bags need to be picked up one by one by large equipment, loaded onto trucks, and transported to large sites for storage. Due to the large volume and low density of round bags, the investment costs for transportation and site are increased.

[0006] 3. Round bags are bulky and require a very large space. They are particularly difficult to protect from rain in summer. Once they get wet in the rain, they are basically unusable, resulting in huge losses. They are also inconvenient to store.

[0007] Besides storage, existing straw processing equipment mainly includes complete sets of equipment for making feed and complete sets of equipment for making biomass pellets. Both types of equipment are characterized by large investment, high equipment power, and large production sites. At the same time, the production process requires crushing and dust removal, and is basically carried out in the open air without dust removal equipment, resulting in a lot of dust and pollutants, which pollutes the environment.

[0008] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a self-propelled straw harvesting and granulation machine. Summary of the Invention

[0009] The purpose of this invention is to provide a self-propelled straw harvesting and pelletizing machine with a novel structure, a high degree of integration of the processes of picking up, crushing, dust removal, and storage of leftover straw in the field, and the ability to improve the working environment and ultimately produce biomass pellets.

[0142] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0143] See Figures 1 to 13 As shown;

[0144] This embodiment provides a self-propelled straw harvesting and granulating machine, which includes:

[0145] Frame 1, frame 1 has a running gear;

[0146] The cab 101 is located at the front of the frame 1;

[0153] The blow-suction straw picking mechanism 2 includes:

[0154] Pickup machine housing 201;

[0155] The fan main shaft 203 is located inside the pickup machine housing 201 and is rotatably connected to the pickup machine housing 201 via bearings;

[0156] The transmission shaft assembly 202 is integrated into the rear side of the pickup housing 201; and

[0157] Hammer picking mechanism 204 located at the bottom of the front side of the straw picker;

[0158] The transmission shaft assembly 202 is connected to the hammer blade picking mechanism 204 via the transmission belt 20204 to drive the hammer blade picking mechanism 204 to move.

[0159] The transmission shaft assembly 202 is connected to the fan main shaft 203 to drive the fan main shaft 203 to rotate;

[0160] The fan main shaft 203 integrates the fan blades 20301 and the crushing blades 20302;

[0161] The upper end of the picking machine housing 201 has a picking mechanism outlet 20105, and the lower end of the picking machine housing 201 has a picking mechanism air outlet 20106. The straw enters the straw picking machine through the hammer picking mechanism 204, and is crushed by the crushing blade 20302 by air conveying and then discharged through the picking mechanism outlet 20105.

[0162] The aforementioned pickup housing 201 includes:

[0163] Fan blade housing 20101 and channel 20102;

[0164] The wind turbine blade 20301 is located inside the wind turbine casing 20101;

[0165] The channel section 20102 is connected to the fan blade housing section 20101, and the upper end of the channel section 20102 is the material outlet 20105 of the picking mechanism, and the lower end of the channel section 20102 is the air outlet 20106 of the picking mechanism.

[0166] The pickup housing 201 also includes a crushing blade housing 20103, with the crushing blade 2030 located inside the crushing blade housing 20103, and the blower main shaft 203 and the crushing blade housing 20103 being rotatably connected by bearings;

[0167] The front end of the crusher housing 20103 has a hammer mechanism housing 20104, and the hammer picking mechanism 204 is located inside the hammer mechanism housing 20104;

[0168] Hammer pick-up mechanism 204 includes:

[0169] Gearbox 20401;

[0170] Two pickup shafts 20403 are arranged at intervals. Multiple sets of hammer blades 20404 are arranged at intervals along the axial direction of the pickup shafts 20403. Each set of hammer blades 20404 includes two hammer blades 20404 distributed at 180° along the circumference of the pickup shafts 20403. The arrangement directions of the hammer blades 20404 on the two pickup shafts 20403 are perpendicular to each other.

[0171] One end of the pickup shaft 20403 is connected to the gearbox 20401 for transmission, and the other end of the pickup shaft 20403 is rotatably connected to the hammer mechanism housing 20104 through a bearing;

[0172] The two picking shafts 20403 rotate in opposite directions, and the space between the adjacent hammers 20404 of the two picking shafts 20403 is the straw picking space.

[0173] This embodiment discloses a novel straw picking machine, which includes a picking machine housing 201, a fan main shaft 203, a transmission shaft assembly 202, and a hammer blade picking mechanism 204. In order to realize long-distance material transportation, the fan main shaft 203 is integrated inside. The fan main shaft 203 rotates under the drive of the transmission shaft assembly 202, thereby driving the fan blades 20301 and the crushing blades 20302 on it to rotate. In addition, the residual air generated by the rotation of the fan blades 20301 can be discharged through the air outlet 20106 of the picking mechanism to blow up the straw on the ground, thereby improving the picking effect of the hammer blade picking mechanism 204.

[0174] This section details the structure of the hammer-collecting mechanism 204, which includes two collecting shafts 20403. Each collecting shaft 20403 has multiple hammers 20404 fixed to it via pins. The hammers 20404 are arranged symmetrically at 180° on the same collecting shaft 20403, with multiple sets of hammers 20404 spaced apart along the axial direction of the collecting shaft 20403. Furthermore, the two collecting shafts 20403 are adjusted to rotate in opposite directions via a gearbox 20401. This creates a negative pressure zone through the reverse rotation of the hammers 20404, thereby drawing the straw into the collector. Additionally, the hammers 20404 in this embodiment also have a crushing function, performing an initial crushing operation on the straw.

[0175] Preferably, the conduction shaft assembly 202 in this embodiment includes:

[0176] Conducting shaft 20201;

[0177] The first transmission wheel 20202 is integrated into one end of the transmission shaft 20201; and

[0178] Angle 20203 is integrated at the other end of the transmission shaft 20201;

[0179] The gearbox 20401 has a second drive wheel 20402, and the first drive wheel 20202 and the second drive wheel 20402 are driven by a drive belt 20204.

[0180] The transmission shaft 20201 is connected to the fan main shaft 203 via the angle bracket 20203 to drive the fan main shaft 203 to rotate.

[0181] The power source for the transmission shaft assembly 202 comes from an external source. When the external power mechanism drives the transmission shaft 20201 to rotate, one end of the transmission shaft 20201 drives the second transmission wheel 20402 of the gearbox 20401 to rotate via the first transmission wheel 20202 and the transmission belt 20204, thereby driving the gears inside the gearbox 20401 to rotate. The other end of the transmission shaft 20201 adjusts the transmission direction via the angle device 20203 to drive the fan main shaft 203 to rotate.

[0182] The straw picker also features ground wheels integrated into the bottom (20107).

[0183] The first transmission wheel 20202 and the second transmission wheel 20402 are externally mounted with a protective shell 205 for the transmission wheels.

[0184] During operation, the height of the picker can be adjusted to observe the stubble height. The height of the ground wheel 20107 can be adjusted to ensure that the stubble height is around 80mm.

[0185] The blow-suction straw collector of this embodiment integrates a hammer picking mechanism 204 at the bottom, which internally integrates a fan blade 20301 and a crushing blade 20302. The hammer picking mechanism 204 and the fan main shaft 203 are driven to rotate simultaneously through the transmission shaft assembly 202. The hammer blades 20404 pick up the straw, and after it is crushed by the hammer picking mechanism 204 and the crushing blades 20302, it is discharged from the picking mechanism outlet 20105 by air conveying. The air outlet 20106 blows the straw up, and the hammer blades 20404, which rotate in the opposite direction, form a negative pressure zone at this point. The negative pressure draws the blown straw into the collector, improving the straw picking effect and meeting the straw processing requirements without secondary operations.

The pneumatic conveying can realize long-distance material transportation. The picking shafts rotating in opposite directions can form a vortex airflow. The blower generates a negative pressure zone to suck in the straw, making the picking cleaner and more thorough.

Dust is removed by a downstream dust removal mechanism 3 before the material is conveyed to a crushing mechanism 4 for further crushing. After crushing, the material is distributed by a material distribution mechanism 5 and then transported by a pellet elevator 6 to a pellet storage tank 7. This device has a high degree of integration, produces high-density, small-volume pellets, reduces transportation costs and storage space, and allows for long-term storage.
