Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a self-propelled field straw pelletizer. Background Technology

[0002] The traditional method of treating straw in the field is to burn it directly. However, this method produces a large amount of harmful smoke and dust, polluting the environment and affecting human respiratory health. Therefore, with the need for green agricultural production, the traditional burning method is no longer used for treating straw in the field.

[0003] Currently, most field straw is processed using self-propelled pelletizers, the structure of which is shown in the attached figure. Figure 1 As shown, it mainly consists of a work vehicle 100, a blow-suction feeding hopper 101, a feeding duct 102, a cyclone separator 103, a granulation hopper 104, and a collection hopper 105. The work vehicle operates in the field, sucking straw into the blow-suction feeding hopper and feeding it through the feeding duct into the cyclone separator by air power. The cyclone separator discharges the air from the top, while the straw enters the granulation hopper downwards for cutting and granulation. Finally, the straw pellets are collected through the collection hopper.

[0004] The aforementioned pellet mill can conveniently recycle and process field straw. However, during the current use of this pellet mill, it has been found that significant dust is generated on both sides of the blow-suction feeding hopper during the wind-powered feeding process. The pellet mill itself does not have a corresponding dust suppression structure. In view of this, we propose a self-propelled field straw pellet mill, which improves upon the structure and shortcomings of the existing pellet mill. Utility Model Content

[0005] The purpose of this invention is to provide a self-propelled field straw pelletizer to solve the problems existing in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] The self-propelled field straw pelletizer includes a work vehicle, which integrates a blow-suction feeding hopper, a feeding air duct, a cyclone separator, a pelletizing hopper, and a collection hopper. A first dust suppression mechanism is installed on both sides of the work vehicle. The first dust suppression mechanism includes: a first water tank, fixedly installed on the side of the work vehicle; a water pump, fixedly installed to the first water tank, with its inlet pipe extending to the bottom of the first water tank; a transverse water pipe, fixedly installed to the side of the work vehicle, with its distal end extending towards the blow-suction feeding hopper, and the output end of the water pump connected to the transverse water pipe; and multiple atomizing nozzles, each of which is equidistantly installed and fixed to the transverse water pipe via a connector.

[0008] As a limitation of the present utility model, the cyclone separator includes a cylinder, an exhaust duct and a discharge port. The feeding duct is connected to the cylinder along the tangential direction on the upper side of the cylinder. The exhaust duct is located at the top of the cylinder. The discharge port is located at the lower end of the cylinder and is connected to the granulation hopper. The top of the working vehicle is also provided with a second dust suppression mechanism that matches the exhaust duct.

[0009] As a limitation of the present utility model, the second dust suppression mechanism includes a second water tank, an air inlet pipe, and an air outlet pipe; the second water tank is fixedly installed on the top of the work vehicle; the air inlet pipe is vertically arranged on the top of the second water tank, the lower end of the air inlet pipe extends to the bottom of the second water tank, and the upper end of the air inlet pipe is connected to the exhaust duct; the air outlet pipe is connected to the top of the second water tank.

[0010] As a limitation of the present invention, both the first water tank and the second water tank are provided with water inlets.

[0011] As a limitation of the present invention, a drain outlet is also provided on the lower side of the second water tank.

[0012] As a limitation of the present invention, both the first water tank and the second water tank are fixed to the work vehicle by multiple clamps.

[0013] As a limitation of the present invention, the horizontal water pipe is installed and fixed to the work vehicle through multiple mounting brackets.

[0014] As a limitation of the present invention, the first water tank and the second water tank are made of transparent material or have transparent observation windows.

[0015] This utility model has the following beneficial effects:

[0016] ① During the operation of the work vehicle, the water pump of the first dust suppression mechanism is turned on, thereby pumping the water in the first water tank into the horizontal water pipe, and spraying fine water mist through the atomizing nozzles connected to each joint, thereby effectively suppressing the dust on both sides of the blowing and suction feeding hopper.

[0017] ② When the cyclone separator is venting, the air will enter the second water tank through the air inlet pipe. Since the air inlet pipe extends to the bottom of the second water tank, the water in the second water tank will submerge the lower side of the air inlet pipe. With this setting, the air discharged from the exhaust duct will enter the water, and the impurities and dust in the air will be retained in the second water tank, achieving the water washing effect of the exhaust air and removing the impurities and dust in the air. Finally, the air that has been washed and cleaned can be discharged through the air outlet pipe, achieving the effect of removing impurities from the exhaust air. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example:

[0028] like Figure 1The existing self-propelled field straw pelletizer shown includes a work vehicle 100, which integrates a blow-suction feeding hopper 101, a feeding duct 102, a cyclone separator 103, a pelletizing hopper 104, and a collection hopper 105. In this utility model, the work vehicle 100 is existing equipment. As those skilled in the art can understand, when the work vehicle 100 performs field straw recycling and pelletizing operations, it collects field straw through the blow-suction feeding hopper 101 and feeds the straw into the cyclone separator 103 through the feeding duct 102 by wind power. The cyclone separator 103 can separate air and material. The air is discharged from the top, while the straw enters the pelletizing hopper 104 from the bottom for cutting and pelletizing. Finally, the straw pellets are recycled through the collection hopper 105.

[0029] This embodiment addresses the issue of excessive dust generation on both sides of the blow-suction feed hopper 101 during operation of the work vehicle 100. Specifically, it improves upon this by installing a first dust suppression mechanism 110 on both sides of the work vehicle 100 to reduce dust on both sides of the blow-suction feed hopper 101. The structure of the first dust suppression mechanism 110 is as follows:

[0030] The work vehicle 100 is equipped with a first dust suppression mechanism 110 on both sides, and the first dust suppression mechanism 110 includes:

[0031] The first water tank 111 is fixedly installed on the side of the work vehicle 100;

[0032] A water pump 112 is installed and fixed to the first water tank 111, and the inlet pipe of the water pump 112 extends to the bottom of the first water tank 111.

[0033] A horizontal water pipe 113 is installed and fixed to the side of the work vehicle 100. The far end of the horizontal water pipe 113 extends toward the blow-suction feed hopper 101. The output end of the water pump 112 is connected to the horizontal water pipe 113.

[0034] Atomizing nozzle 114, there are multiple atomizing nozzles 114, and each atomizing nozzle 114 is installed and fixed at equal distances to the horizontal water pipe 113 through a connector 115.

[0035] During the operation of the work vehicle 100, the water pump 112 of the first dust suppression mechanism 110 is turned on, thereby pumping the water in the first water tank 111 into the horizontal water pipe 113, and spraying fine water mist through the atomizing nozzles 114 connected to each joint 115, thereby effectively suppressing the dust on both sides of the blowing and suction feeding hopper 101.

[0036] Regarding the structural description of the cyclone separator 103 in this embodiment, the cyclone separator 103 is an existing device, mainly used for separating air and material, such as... Figure 1 , Figure 2 as well as Figure 4 As shown, the cyclone separator 103 includes a cylinder 1031, an exhaust duct 1032, and a discharge port 1033. The feeding duct 102 is connected to the cylinder 1031 along the tangential direction on the upper side of the cylinder 1031. The exhaust duct 1032 is located at the top of the cylinder 1031, and the discharge port 1033 is located at the lower end of the cylinder 1031 and is connected to the granulation hopper 104. When the straw is fed into the cylinder 1031 by the pneumatic feeding, it is then processed by the cyclone separator 103, causing the straw to enter the granulation hopper 104 from the discharge port 1033 at the lower end of the cylinder 1031, while the air is discharged from the exhaust duct 1032 at the upper end of the cylinder 1031.

[0037] This embodiment also addresses the issue that the air discharged from the exhaust duct 1032 of the work vehicle 100 contains dust and impurities during operation. Specifically, a second dust suppression mechanism 120 is installed on the top of the work vehicle 100 to remove dust from the air discharged from the exhaust duct 1032. The structure of the second dust suppression mechanism 120 is as follows:

[0038] The top of the work vehicle 100 is also equipped with a second dust suppression mechanism 120 that matches the exhaust duct 1032. The second dust suppression mechanism 120 includes a second water tank 121, an air inlet pipe 122, and an air outlet pipe 123.

[0039] The second water tank 121 is installed and fixed to the top of the work vehicle 100;

[0040] The air inlet pipe 122 is vertically arranged at the top of the second water tank 121, the lower end of the air inlet pipe 122 extends to the bottom of the second water tank 121, and the upper end of the air inlet pipe 122 is connected to the exhaust duct 1032.

[0041] The air outlet pipe 123 is connected to the top of the second water tank 121.

[0042] When the exhaust duct 1032 exhausts air, the air will enter the second water tank 121 through the air inlet pipe 122. Since the air inlet pipe 122 extends to the bottom of the second water tank 121, the water in the second water tank 121 will submerge the lower side of the air inlet pipe 122. With this setting, the air discharged from the exhaust duct 1032 will enter the water, and the impurities and dust in the air will be retained in the second water tank 121, achieving the water washing effect of the exhaust air and removing the impurities and dust in the air. Finally, the air that has been washed and cleaned can be discharged through the air outlet pipe 123, achieving the impurity removal effect of the exhaust air from the exhaust duct 1032.

[0043] As a structural description of the above embodiments, such as Figures 3 to 5As shown, both the first water tank 111 and the second water tank 121 are provided with a water inlet 130, and the second water tank 121 is also provided with a drain outlet 131 on its lower side. The purpose of this arrangement is to facilitate the addition of water to the first water tank 111 and the second water tank 121 through the water inlet 130. It is understood that the water inlet 130 is provided with a removable cover. At the same time, people can discharge the wastewater containing impurities from the second water tank 121 through the drain outlet 131. It is understood that the drain outlet 131 is also provided with a removable cover.

[0044] As another structural description of the above embodiments, such as Figure 3 and Figure 4 As shown, both the first water tank 111 and the second water tank 121 are fixed to the work vehicle 100 via multiple clamps 140, and the transverse water pipe 113 is fixed to the work vehicle 100 via multiple mounting brackets 141. The clamps 140 are commonly used fixing structures that can effectively install the first water tank 111 and the second water tank 121. The mounting brackets 141 can be designed to fit the spatial position of the transverse water pipe 113, effectively installing and fixing the transverse water pipe 113.

[0045] As another structural feature of the above embodiment (not shown in the figures), the first water tank 111 and the second water tank 121 are made of transparent material or have transparent observation windows. This arrangement allows people to easily observe the water levels in the first water tank 111 and the second water tank 121, as well as the impurities in the second water tank 121, thus facilitating the addition of water and the discharge of wastewater as needed.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
