Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery technology, and in particular, to a baler compression device with pressure measurement function. Furthermore, this application also relates to a baler including the aforementioned baler compression device with pressure measurement function. Background Technology
[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.
[0003] In the field of agricultural machinery, my country is rich in agricultural biomass resources such as straw and forage, which are of great significance to the development of animal husbandry. However, due to the low density of straw and forage, the large storage space required, and their uneven geographical distribution, the collection and transportation of these materials face significant difficulties. Therefore, the use of balers can compress loose straw and forage into bales of a certain size and shape, reducing their volume and improving their quality. This effectively solves the problems of collection and transportation, thereby achieving the goal of industrial utilization of straw and forage resources. Simultaneously, it effectively addresses the problem of severe weight loss in cattle and sheep due to winter forage shortages, thus promoting the development of animal husbandry and yielding significant economic and social benefits.
[0004] For example, Chinese Patent Publication No. CN219741280U discloses a baler compression device guiding system and a baler, which can ensure the movement direction of the compression device through the baler compression device guiding system, which helps to reduce the frictional power consumption of the compression device.
[0005] In existing baling machines, bale density adjustment primarily relies on hydraulic cylinders positioned on the left and right sides of the baling chamber. These cylinders push the chamber walls inward, creating friction between the material and the walls. The density is then controlled by adjusting the pressure of the hydraulic cylinders. However, this method cannot achieve real-time monitoring of compression force, thus failing to obtain the appropriate compression force required for the ideal bale density.
[0006] It is evident that the performance of the compression device, as a crucial component of the baler, directly impacts the quality of the bales. However, existing compression devices cannot measure piston pressure in real time, hindering precise adjustment of bale compression density and making it difficult to effectively meet bale quality requirements and improve operational efficiency. Utility Model Content
[0007] In view of at least one of the above technical problems, this application provides a baler compression device with pressure measurement function, which can monitor the compression force of the compression piston in real time through the connecting rod measuring component, and can reasonably match the working compression force according to the different densities required by different types of forage, thereby controlling the compression power loss of the baler.
[0008] This application also provides a baler that includes the above-mentioned baler compression device with pressure measurement function.
[0009] According to one aspect of this application, a baler compression device with pressure measurement function is provided, including a compression piston, a crank, and a connecting rod mechanism. The crank is connected to and driven by a baler drive mechanism to perform reciprocating motion. The connecting rod mechanism connects the crank to the compression piston. Under the drive of the baler drive mechanism, the crank drives the compression piston to reciprocate through the connecting rod mechanism to compress the material into bales. The connecting rod mechanism includes a connecting rod measurement component, which includes a connecting rod and a pressure sensor. The two ends of the connecting rod are respectively connected to the compression piston and the crank. The pressure sensor is located at one end of the connecting rod and is connected to the compression piston or the crank. The pressure sensor is used to monitor the pressure on the connecting rod.
[0010] In some embodiments of this application, the connecting rod measuring assembly further includes two connectors, which are respectively connected to the two ends of the connecting rod. The connectors at both ends of the connecting rod are respectively connected to the compression piston and the crank. At least one connector has a limiting hole for limiting the pressure sensor.
[0011] In some embodiments of this application, reinforcing ribs are provided between the sidewall of the connecting rod and the connecting member.
[0012] In some embodiments of this application, a limit ring is provided on the side of the connector away from the connecting rod. The limit ring is used to limit the preset mounting platform on the compression piston or crank.
[0013] In some embodiments of this application, the connecting rod measuring assembly further includes a conductive element. A central through hole is provided in the connecting rod, and the conductive element is disposed in the central through hole of the connecting rod. The first end of the conductive element is connected to the end of the connecting rod away from the pressure sensor, and the pressure sensor is installed at the second end of the conductive element.
[0014] In some embodiments of this application, the second end of the conductive member is provided with a mounting groove for accommodating a pressure sensor, and an elastic clamping member is provided in the mounting groove for clamping and limiting the pressure sensor.
[0015] In some embodiments of this application, the resilient clamping member includes at least one of a spring latch, a resilient arc plate, and a resilient boss.
[0016] In some embodiments of this application, a limiting guide is provided on the inner wall of the central through hole of the connecting rod, which is used to support and limit the transmission component.

A limiting groove is formed on the side of the limiting plate near the conductive member, and the limiting groove is used to support and limit the conductive member.
[0018] According to another aspect of this application, a baler is also provided, which includes the aforementioned baler compression device with pressure measurement function.
[0019] This application has the following beneficial effects:
[0020] This application's baler compression device with pressure measurement function connects the compression piston and crank via a linkage mechanism. The crank is connected to the baler's drive mechanism to drive the crank's movement, which in turn drives the compression piston to reciprocate through the linkage mechanism, continuously compressing the material into bales. The linkage measurement component of the linkage mechanism can monitor the pressure on the linkage mechanism in real time, i.e., monitor the compression force of the compression piston, facilitating precise adjustment of the desired bale density. The connecting rod of the linkage measurement component connects the compression piston and crank, and one end of the connecting rod is equipped with a pressure sensor. By connecting the pressure sensor to the compression piston or crank, the pressure on the connecting rod can be detected, allowing real-time monitoring of the compression force of the compression piston. This enables the appropriate matching of working compression force according to the different densities required for different types of forage, thereby controlling the baler's compression power loss and precisely controlling the bale density to meet various processing needs.
[0021] The baler of this application also possesses the aforementioned beneficial effects. It further includes a mechanism that transforms the intermediate connecting rod of the baler's compression device into a measuring mechanism capable of measuring the compressive force during the operation of the compression piston. This mechanism transmits the torque generated by the crank rotation in the compression device to the compression piston and simultaneously measures the compressive force during piston operation. The connecting rod measuring assembly has a simple overall structure, is easy to manufacture, and offers good assembly adjustability. By measuring the pressure of the baler's compression piston during operation, the working compression force can be rationally matched according to the different densities required for different types of forage, thereby controlling the baler's compression power loss.

[0027] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.
[0028] Figure 1 This is a schematic diagram of the overall structure of a preferred embodiment of this application; Figure 2 This is a schematic diagram of the linkage measurement assembly according to a preferred embodiment of this application.
[0029] A baler compression device with pressure measurement function includes a compression piston 1, a crank 2, and a connecting rod mechanism 3. The crank 2 is connected to the baler drive mechanism and driven to reciprocate. The connecting rod mechanism 3 connects the crank 2 to the compression piston 1. The crank 2 is used to drive the compression piston 1 to reciprocate under the drive of the baler drive mechanism through the connecting rod mechanism 3 to compress the material into bales. The connecting rod mechanism 3 includes a connecting rod measuring component 31, which includes a connecting rod 312 and a pressure sensor 314. The two ends of the connecting rod 312 are respectively connected to the compression piston 1 and the crank 2. The pressure sensor 314 is located at one end of the connecting rod 312 and is connected to the compression piston 1 or the crank 2. The pressure sensor 314 is used to monitor the pressure on the connecting rod 312.
[0030] Here, "connecting rod 312" refers to the structure that connects the compression piston 1 to the crank 2. In some embodiments, the connecting rod 312 is a rod-shaped structure with a central through hole, and the pressure sensor 314 can be bolted to the inner wall of the central through hole. The compression piston 1 is provided with a first adapter 11, the first end of which is hinged to the body of the compression piston 1, and the second end of which is connected to the connecting rod 312. The crank 2 is provided with a rotatable second adapter 21, which is connected to the connecting rod 312.
[0031] This application connects the compression piston 1 and the crank 2 via a linkage mechanism 3. The crank 2 is connected to the drive mechanism of the baler, thereby driving the crank 2 to move. This, in turn, drives the compression piston 1 to reciprocate through the linkage mechanism 3, continuously compressing the material into bales. The linkage measuring component 31 of the linkage mechanism 3 can monitor the pressure on the linkage mechanism 3 in real time, i.e., monitor the compression force of the compression piston 1, facilitating precise adjustment of the desired bale density. The connecting rod 312 of the linkage measuring component 31 connects the compression piston 1 and the crank 2. One end of the connecting rod 312 is equipped with a pressure sensor 314. Connected to the compression piston 1 or the crank 2, the pressure sensor 314 detects the pressure on the connecting rod 312, enabling real-time monitoring of the compression force of the compression piston 1. This allows for the appropriate matching of the working compression force according to the different densities required for different types of forage, thereby controlling the baler's compression power loss and precisely controlling the bale density to meet various processing needs.
[0032] Preferably, please refer to Figure 2 As shown, the connecting rod measuring assembly 31 also includes a connector 311. There are two connectors 311, which are respectively connected to the two ends of the connecting rod 312. The connectors 311 at both ends of the connecting rod 312 are respectively connected to the compression piston 1 and the crank 2. At least one connector 311 has a limit hole, which is used to limit the pressure sensor 314.
[0033] It is understandable that by setting connectors 311 at both ends of the connecting rod 312, it serves to connect to the compression piston 1 and the crank 2 respectively. At the same time, the connector 311 at one end can also limit the pressure sensor 314, which helps to improve the measurement accuracy of the pressure sensor 314.
[0034] Optionally, the connector 1 adopts a rectangular or circular plate structure. The plate structure connector 1 has screw holes and is connected to the connecting rod 312 by bolts, which facilitates the disassembly and assembly of the connecting rod measuring assembly 31, especially the disassembly, assembly, and maintenance of the pressure sensor 314.
[0035] Preferably, please refer to Figure 2 As shown, a reinforcing rib is provided between the side wall of the connecting rod 312 and the connecting member 311.
[0036] It is understandable that by setting reinforcing ribs between the side wall of the connecting rod 312 and the connecting member 311, the connection stability between the connecting rod 312 and the connecting member 311 can be enhanced, thereby reducing the loss in the process of the connecting rod 312 transmitting the force of the crank 2, which is beneficial to ensuring the measurement accuracy of the pressure sensor 314.
[0037] Preferably, a limit ring is provided on the side of the connector 311 away from the connecting rod 312. The limit ring is used to limit the preset mounting platform on the compression piston 1 or crank 2.
[0038] It is understandable that the connecting rod 312 is connected to the compression piston 1 or the crank 2 respectively through the connecting piece 311. By setting a limiting ring on the connecting piece 311 to limit the preset installation platform on the compression piston 1 or the crank 2, the connecting piece 311 can be quickly and accurately located for installation, and the limiting effect of the connecting piece 311 can be strengthened, which is conducive to improving the installation efficiency and stability of the connecting piece 311.
[0039] In some embodiments, a first adapter 11 is provided on the compression piston 1, the first end of the first adapter 11 is hinged to the body of the compression piston 1, and the second end of the first adapter 11 is connected to the connector 311. A rotatable second adapter 21 is provided on the crank 2, and the second adapter 21 is connected to the connector 311. Both the first adapter 11 and the second adapter 21 are rod-shaped or block-shaped structures, and both the first adapter 11 and the second adapter 21 are pre-set with an installation platform that can cooperate with the limiting retaining ring.
[0040] Preferably, please refer to Figure 2 As shown, the connecting rod measuring assembly 31 also includes a conductor 313. A central through hole is provided in the connecting rod 312. The conductor 313 is located in the central through hole of the connecting rod 312. The first end of the conductor 313 is connected to the end of the connecting rod 312 away from the pressure sensor 314. The pressure sensor 314 is installed at the second end of the conductor 313.
[0041] It is understood that the connecting rod 312 provides installation space for the transmission element 313. The first end of the transmission element 313 can be connected to the inner wall of the central through hole through the connecting rod. In some embodiments, the connecting rod 312 is provided with connecting elements 311 at both ends, and the first end of the transmission element 313 can be connected to the connecting element 311. The second end of the transmission element 313 provides installation space for the pressure sensor 314, which can stably install and limit the pressure sensor 314.
[0042] It should be noted that the shape of the mounting groove on the conductive component 313, as a connection port, needs to be matched with the structure of the pressure sensor 314 to ensure stable positioning of the pressure sensor 314.
[0043] In some embodiments, the first end of the transmission member 313 is connected to the compression piston 1 or the crank 2, and the second end of the transmission member 313 has a mounting groove for mounting and limiting the pressure sensor 314. The relative force generated by the compression piston 1 when compressing and molding the material is transmitted and fed back to the transmission member 313, and the pressure value is monitored by the pressure sensor 314 on the transmission member 313. The pressure value of the compression piston 1 can also be monitored in real time.
[0044] Preferably, the second end of the conductive member 313 is provided with a mounting groove for accommodating the pressure sensor 314, and an elastic clamping member is provided in the mounting groove for clamping and limiting the pressure sensor 314.
[0045] It is understandable that the mounting groove of the transmission component 313 serves to limit the installation of the pressure sensor 314. By setting an elastic clamping element in the mounting groove, the clamping and limiting effect on the pressure sensor 314 can be strengthened, ensuring the installation stability of the pressure sensor 314, reducing the phenomenon that the pressure sensor 314 is prone to displacement, and helping to further improve the measurement accuracy of the pressure sensor 314.
[0046] Optionally, the resilient clamping element includes at least one of a spring latch, a resilient curved plate, and a resilient boss.
[0047] Understandably, the spring latch, elastic curved plate, and elastic boss all possess a certain degree of elasticity or deformation capability, enabling them to compress the pressure sensor 314 and clamp it in place. Specifically, the annular array of elastic clamping elements arranged on the sidewall of the mounting groove stably limits the pressure sensor 314 to the center of the mounting groove, thus achieving a centering effect and ensuring that the force lines of the measuring force are as straight as possible, thereby guaranteeing the measurement accuracy of the pressure sensor 314.
[0048] Preferably, a limiting guide is provided on the inner wall of the central through hole of the connecting rod 312, which is used to support and limit the transmission member 313.
[0049] It is understandable that by using the limiting guide to support and limit the transmission component 313, the transmission component 313 and the connecting rod 312 are set coaxially, ensuring that the transmission component 313 is not prone to positional displacement, thereby ensuring the stability of the position of the pressure sensor 314 at one end of the transmission component 313 and ensuring the accuracy of pressure measurement.
[0050] In this preferred embodiment, the limiting guide includes a limiting plate, which is arranged in a ring array on the inner wall of the central through hole. A limiting groove is formed on the side of the limiting plate near the conductor 313, and the limiting groove is used to support and limit the conductor 313.
[0051] It is understandable that by arranging the limiting plates in a ring array, the transmission component 313 can be supported and limited in all directions, so as to stably limit the transmission component 313 at the center line of the central through hole of the connecting rod 312, avoid the transmission component 313 from being prone to positional displacement, and thus ensure the accurate measurement of the pressure sensor 314.
[0052] Optionally, the transmission component 313 adopts a cylindrical rod structure, which can be stably set at the centerline position of the central through hole of the connecting rod 312 in conjunction with the limiting groove of the limiting plate.
[0053] According to another aspect of this application, a baler is also provided, which includes the aforementioned baler compression device with pressure measurement function.
[0054] The baler of this application also has the aforementioned beneficial effects. It further includes converting the intermediate connecting rod of the baler's compression device into a measuring mechanism that can measure the compressive force of the compression piston 1 during operation. On the one hand, it can transmit the torque power generated by the rotation of the crank 2 in the compression device to the compression piston 1; on the other hand, it can measure the compressive force of the compression piston 1 during operation. The connecting rod measuring assembly 31 has a simple overall structure, is easy to manufacture, and has good assembly adjustability. By measuring the pressure of the baler's compression piston 1 during operation, the working compression force can be reasonably matched according to the different densities required for different types of forage, thereby controlling the baler's compression power loss.
[0055] In this application, crank 2 receives power from the baler's drive mechanism, compression piston 1 compresses loose material into shape, and the connecting rod mechanism 3 connects crank 2 and compression piston 1. During the baler's operation, the compression piston 1 continuously presses and shapes the loose material into regular bales with a certain density. The working pressure of the compression piston 1 affects the density of the bales. Therefore, to detect the working pressure of the compression piston 1 in real time, this application aims to provide a technical solution for a pressure measuring device for the compression piston 1 of a baler. Through the connecting rod measuring component 31, the working compression force of the compression piston 1 is obtained, thereby accurately adjusting the desired ideal bale density and reasonably matching the working compression force to control the baler's compression power loss.
