Description

Technical Field

[0001] This utility model relates to the field of pesticide processing technology, specifically to a double-bladed mixer for pesticide processing. Background Technology

[0002] In the development of modern agriculture, pesticides, as key agricultural inputs for ensuring crop yields and controlling pests and diseases, are facing increasing demands for refined and efficient production and processing. The dual-blade mixer, with its structural advantage of simultaneous mixing via twin blades, can achieve rapid shearing and convection mixing of multiple components such as solid active ingredients, inert carriers, and functional adjuvants in pesticide production. The mixing uniformity can reach over 95%, and the equipment's processing capacity is suitable for the batch production needs of small and medium-sized pesticide processing plants. Therefore, it has become a core mixing device in the current production process of solid formulation pesticides such as powders and wettable powders.

[0003] In the current technology, the double-blade mixer used for pesticide processing is affected by both the structural characteristics of the double-blade mixer itself and the physical properties of the materials. When the blades rotate at high speed, local negative pressure and airflow disturbance will be formed inside the mixing chamber. When the material enters from the feed inlet, the airflow will carry some light materials to splash to the outside of the feed inlet. The splashed material will adhere to the equipment shell, operating table and ground around the feed inlet, which not only increases the workload of workshop cleaning, but also affects the quality stability of pesticide products. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a double-blade mixer for pesticide processing, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a double-blade mixer for pesticide processing; it includes a housing, a motor fixedly connected to the left side of the housing, two sets of blades fixedly connected to the output end of the motor, the blades rotating inside the housing, a feed inlet fixedly connected to the top of the housing, and a shielding component provided between the feed inlet and the housing; The shielding assembly includes a bearing fixedly connected to the housing, a connecting rod fixedly connected to the inner ring of the bearing, a shielding plate fixedly connected to the bottom of the connecting rod, the top of the shielding plate fitting against the inner wall of the housing, a ratchet fixedly connected to the top of the connecting rod, and two sets of movable chambers fixedly connected to the housing at the front and rear ends of the connecting rod. A rotating rod is rotatably connected inside the movable chamber, and a pawl is fixedly connected to the top of the rotating rod, the pawl engaging with the ratchet.

[0006] Furthermore, a torsion spring is wound around the surface of the rotating rod in the movable compartment, and the torsion spring is located at the middle position on the rotating rod.

[0007] Furthermore, the outer wall of the pawl is provided with several sets of grooves, and the several sets of grooves are designed to be equally spaced along the arc of the outer wall of the pawl.

[0008] Furthermore, several sets of grips are fixedly connected at equal intervals on the outer wall of the connecting rod above the housing, and all grips are cylindrical in design.

[0009] Furthermore, a protective assembly is provided on the top of the ratchet. The protective assembly includes a slide cylinder coaxially fixedly connected to the top of the ratchet. A spring is fixedly connected inside the slide cylinder. A slide rod is fixedly connected to the other end of the spring. The slide rod is slidably connected to the slide cylinder. A sealing cover is fixedly connected to the left side of the slide rod.

[0010] Furthermore, the sealing cap is designed to be transparent, and a sealing ring is fixedly connected to the inner wall of the sealing cap at the contact point with the feed inlet.

[0011] Furthermore, the slide rod is cylindrical in design, and the slide cylinder has a countersunk hole that matches the slide rod.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model uses a ratchet to drive a connecting rod to rotate within a bearing. The ratchet, through a pawl, drives a rotating rod to rotate within a movable chamber. The rotating rod acts on a torsion spring, causing the torsion spring to twist. Simultaneously, the pawl rotates out of the tooth groove in the ratchet until the ratchet rotates again. Under the restoring force of the torsion spring, the pawl engages in the next tooth groove of the ratchet, firmly locking the ratchet to prevent it from rotating in the opposite direction. This cycle repeats until the connecting rod drives a baffle plate to block the feed inlet, thus preventing material from splashing out of the housing. This ensures the stability of pesticide product quality, reduces quality risks, reduces workshop cleaning workload, and minimizes material waste.

[0013] 2. This utility model uses the rotation of a ratchet to synchronously drive the slide cylinder and the sealing cover to rotate, so that the sealing cover rotates to the top of the feed inlet. Then, the restoring force of the spring drives the slide rod to return to its original position and slide within the slide cylinder, so that the sealing cover and the top of the feed inlet are tightly fitted together. This achieves the purpose of protecting the feed inlet and prevents dust or foreign objects from entering the housing through the feed inlet when the housing is idle, thus preventing the housing from being contaminated and affecting the subsequent mixing of pesticides.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figures 1 to 5This first embodiment of the present invention discloses a double-blade mixer for pesticide processing, comprising a housing 1, a motor 2 fixedly connected to the left side of the housing 1, two sets of blades 3 fixedly connected to the output end of the motor 2, the blades 3 rotating inside the housing 1, a feed inlet 4 fixedly connected to the top of the housing 1, a shielding assembly 5 provided between the feed inlet 4 and the housing 1, the shielding assembly 5 including a bearing 51 fixedly connected to the housing 1, a connecting rod 52 fixedly connected to the inner ring of the bearing 51, a shielding plate 53 fixedly connected to the bottom of the connecting rod 52, the top of the shielding plate 53 fitting against the inner wall of the housing 1, and a ratchet 54 fixedly connected to the top of the connecting rod 52. Two sets of movable chambers 55 are fixedly connected to the housing 1 at the front and rear ends of the connecting rod 52. A rotating rod 56 is rotatably connected inside the movable chamber 55. A pawl 58 is fixedly connected to the top of the rotating rod 56. Several sets of grooves are opened through the outer wall of the pawl 58. The grooves are designed to be evenly spaced along the arc of the outer wall of the pawl 58, which can increase the friction between the operator's hand and the pawl 58, and reduce the occurrence of hand slippage when the operator manually rotates the pawl 58. The pawl 58 meshes with the ratchet 54. A torsion spring 57 is wound on the surface of the rotating rod 56 in the movable chamber 55. The torsion spring 57 is located in the middle position on the rotating rod 56.

[0020] It is worth noting that several sets of grips are fixedly connected at equal intervals on the outer wall of the connecting rod 52 above the housing 1, and the grips are all cylindrical in design, which makes it easy for the staff to rotate the connecting rod 52 and the ratchet 54, prevents the hand from slipping when rotating the connecting rod 52 or the ratchet 54, and makes it more time-saving and labor-saving for the staff to rotate the connecting rod 52 or the ratchet 54.

[0021] In use, the ratchet 54 drives the connecting rod 52 to rotate within the bearing 51, and the ratchet 54 drives the rotating rod 56 to rotate within the movable chamber 55 via the pawl 58. The rotating rod 56 acts on the torsion spring 57, causing the torsion spring 57 to twist. At the same time, the pawl 58 rotates out of the tooth groove in the ratchet 54 until the ratchet 54 rotates again. Under the restoring force of the torsion spring 57, the pawl 58 engages with the next tooth groove of the ratchet 54, firmly locking the ratchet 54 to prevent it from rotating in the opposite direction. This cycle repeats until the connecting rod 52 rotates itself and drives the baffle plate 53 to the bottom of the feed inlet 4, so that the baffle plate 53 blocks the feed inlet 4, preventing the material inside the housing 1 from splashing out through the feed inlet 4.

[0022] Example 2: Reference Figure 1 , Figures 3 to 5This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a protective component 6 is provided on the top of the ratchet 54. The protective component 6 includes a slide cylinder 61 coaxially fixedly connected to the top of the ratchet 54. A spring 62 is fixedly connected inside the slide cylinder 61, and a slide rod 63 is fixedly connected to the other end of the spring 62. The slide rod 63 is cylindrical. A countersunk hole adapted to the slide rod 63 is provided inside the slide cylinder 61, allowing the slide rod 63 to fully fit against the slide cylinder 61, thereby ensuring the slide rod 63 moves within the slide cylinder 61. To ensure stability during sliding, slide rod 63 is slidably connected to slide cylinder 61. A sealing cover 64 is fixedly connected to the left side of slide rod 63. The sealing cover 64 is transparent. A sealing ring is fixedly connected to the contact point between the inner wall of the sealing cover 64 and the feed inlet 4, which allows the staff to easily observe and understand the hygiene condition inside the feed inlet 4 through the sealing cover 64. At the same time, the sealing cover 64 is tightly fitted to the feed inlet 4 under the action of spring 62 and slide rod 63, thereby ensuring the sealing between the feed inlet 4 and the sealing cover 64.

[0023] In use, the ratchet 54 rotates simultaneously, driving the slide cylinder 61 and the sealing cover 64 to rotate, so that the sealing cover 64 rotates to the top of the feed inlet 4. Then, the restoring force of the spring 62 drives the slide rod 63 to return to its original position and slide within the slide cylinder 61, so that the sealing cover 64 is tightly fitted to the top of the feed inlet 4, thereby achieving the purpose of protecting the feed inlet 4.

[0024] The remaining structure is the same as that in Example 1.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
